Both \TL{} and the \TK{} are cooperative efforts by the \TeX{} +user groups. This document mainly describes \TL{} itself. + +\TL{} includes executables for \TeX{}, \LaTeXe{}, \ConTeXt, +\MF, \MP, \BibTeX{} and many other programs; an extensive collection +of macros, fonts and documentation; and support for typesetting in +many different scripts from around the world. + +For a brief summary of the major changes in this edition of \TL{}, +see the end of the document, section~\ref{sec:history} +(\p.\pageref{sec:history}). + + +\htmlanchor{platforms} +\subsection{Operating system support} +\label{sec:os-support} + +\TL{} contains binaries for many Unix-based platforms, including +\GNU/Linux, \MacOSX, and Cygwin. The included sources can be compiled +on platforms for which we do not provide binaries. + +As to Windows: Windows~7 and later are supported. Windows Vista +may still mostly work, but \TL{} will no longer even install on Windows +XP or earlier. There are no special +64-bit executables for Windows, but the 32-bit executables should +run on 64-bit systems. + +See section~\ref{sec:tl-coll-dists} for alternate solutions +for Windows and \MacOSX. + +\subsection{Basic installation of \protect\TL{}} +\label{sec:basic} + +You can install \TL{} either from \DVD{} or over the Internet +(\url{http://tug.org/texlive/acquire.html}). The net installer itself is +small, and downloads everything requested from the Internet. + +The \DVD{} installer lets you install to a local disk. You cannot run +\TL{} directly from the \TK{} \DVD{} (or its \code{.iso} image), but you +can prepare a runnable installation on, e.g., a \USB{} stick (see +section~\ref{sec:portable-tl}). Installation is described in later +sections (\p.\pageref{sec:install}), but here is a quick start: + +\begin{itemize*} + +\item The installation script is named \filename{install-tl}. It + can operate in a ``gui mode'' given the option \code{-gui} + (default for Windows and \MacOSX), a text mode given + \code{-gui=text} (default for everything else). On Unix + platforms, the former Perl/Tk and wizard modes are still available + if Perl/Tk is installed; see section~\ref{sec:wininst} for + Windows. + +\item One of the installed items is the `\TL\ Manager' program, + named \prog{tlmgr}. Like the installer, it can be used in both \GUI{} + mode and in text mode. You can use it to install and uninstall + packages and do various configuration tasks. + +\end{itemize*} + + +\htmlanchor{security} +\subsection{Security considerations} +\label{sec:security} + +To the best of our knowledge, the core \TeX\ programs themselves are +(and always have been) extremely robust. However, the contributed +programs in \TeX\ Live may not reach the same level, despite everyone's +best efforts. As always, you should be careful when running programs on +untrusted input; to improve safety, use a new subdirectory or chroot. + +This need for care is especially urgent on Windows, since in general +Windows finds programs in the current directory before anything else, +regardless of the search path. This opens up a wide variety of possible +attacks. We have closed many holes, but undoubtedly some remain, +especially with third-party programs. Thus, we recommend checking for +suspicious files in the current directory, especially executables +(binaries or scripts). Ordinarily they should not be present, and +definitely should not normally be created by merely processing a document. + +Finally, \TeX\ (and its companion programs) are able to write files when +processing documents, a feature that can also be abused in a wide +variety of ways. Again, processing unknown documents in a new +subdirectory is the safest bet. + + +\subsection{Getting help} +\label{sec:help} + +The \TeX{} community is active and friendly, and most serious questions +end up getting answered. However, the support is informal, done by +volunteers and casual users, so it's especially important that you do +your homework before asking. (If you prefer guaranteed commercial +support, you can forgo \TL{} completely and purchase a vendor's system; +\url{http://tug.org/interest.html#vendors} has a list.) + +Here is a list of resources, approximately in the order we recommend +using them: + +\begin{description} +\item [Getting started] If you are new to \TeX, the web page +\url{http://tug.org/begin.html} gives a brief introduction to the system. + +\item [\TeX{} FAQ] The \TeX{} FAQ is a huge compendium + of answers to all sorts of questions, from the most basic to the + most arcane. It is included on \TL{} in + \OnCD{texmf-dist/doc/generic/FAQ-en/}, and is available + on the Internet through \url{http://www.tex.ac.uk/faq}. Please + check here first. + +\item [\TeX{} Catalogue] If you are looking for a particular package, +font, program, etc., the \TeX{} Catalogue is the place to look. It is a +huge collection of all \TeX{}-related items. See +\url{http://ctan.org/pkg/catalogue/}. + +\item [\TeX{} Web Resources] The web page +\url{http://tug.org/interest.html} has many \TeX{}-related links, in +particular for numerous books, manuals, and articles on all aspects of +the system. + +\item [support archives] Principal support forums for \TeX\ include +the \LaTeX{} community site at \url{http://latex-community.org/}, the +q\&a site \url{http://tex.stackexchange.com}, the Usenet newsgroup +\url{news:comp.text.tex}, and the mailing list \email{texhax@tug.org}. +Their archives have years of past questions and answers for your +searching pleasure, via, for the latter two, +\url{http://groups.google.com/group/comp.text.tex/topics} and +\url{http://tug.org/mail-archives/texhax}. And a general web search, +for example on \url{http://google.com}, never hurts. + +\item [asking questions] If you cannot find an answer, you can post to +\url{http://latex-community.org/} and +\url{http://tex.stackexchange.com/} through their web interfaces, to +\dirname{comp.text.tex} through Google or your newsreader, or to +\email{texhax@tug.org} through email. But before you post anywhere, +please read this FAQ entry, to maximize your chances of getting a useful +answer: +\url{http://www.tex.ac.uk/cgi-bin/texfaq2html?label=askquestion}. + +\item [\TL{} support] If you want to report a bug or have +suggestions or comments on the \TL{} distribution, installation, or +documentation, the mailing list is \email{tex-live@tug.org}. However, +if your question is about how to use a particular program included in +\TL{}, please write to that program's maintainer or +mailing list. Often running a program with the \code{-{}-help} option +will provide a bug reporting address. + +\end{description} + +The other side of the coin is helping others who have questions. All +the above resources are open to anyone, so feel free to join, start +reading, and help out where you can. + + +% don't use \TL so the \uppercase in the headline works. Also so +% tex4ht ends up with the right TeX. Likewise the \protect's. +\section{Overview of \protect\TeX\protect\ Live} +\label{sec:overview-tl} + +This section describes the contents of \TL{} and the \TK{} of which it +is a part. + +\subsection{The \protect\TeX\protect\ Collection: \protect\TL, + pro\protect\TeX{}t, Mac\protect\TeX} +\label{sec:tl-coll-dists} + +The \TK{} \DVD{} comprises the following: + +\begin{description} + +\item [\TL] A complete \TeX{} system to be installed to disk. Home +page: \url{http://tug.org/texlive/}. + +\item [Mac\TeX] for \MacOSX\ (currently named macOS by Apple, but we +continue to use the older name in this document), this adds a native +\MacOSX\ installer and other Mac applications to \TL{}. Home page: +\url{http://tug.org/mactex/}. + +\item [pro\TeX{}t] An enhancement of the \MIKTEX\ distribution for Windows, +\ProTeXt\ adds a few extra tools to \MIKTEX, and simplifies +installation. It is entirely independent of \TL{}, and has its own +installation instructions. Home page: +\url{http://tug.org/protext/}. + +\item [CTAN] A snapshot of the \CTAN{} repository (\url{http://www.ctan.org/}). + +\end{description} + +\CTAN{} and \pkgname{protext} do not follow the same copying conditions +as \TL{}, so be careful when redistributing or modifying. + + +\subsection{Top level \protect\TL{} directories} +\label{sec:tld} + +Here is a brief listing and description of the top level directories in a +\TL{} installation. + +\begin{ttdescription} +\item[bin] The \TeX{} system programs, arranged by platform. +% +\item[readme-*.dir] Quick overview and useful links for \TL{}, +in various languages, in both \HTML{} and plain text. +% +\item[source] The source to all included programs, including the main + \Webc{}-based \TeX{} distributions. +% +\item[texmf-dist] The principal tree; see \dirname{TEXMFDIST} below. +% +\item[tlpkg] Scripts, programs and data for managing the + installation, and special support for Windows. +\end{ttdescription} + +In addition to the directories above, the installation scripts and +\filename{README} files (in various languages) are at the top level of +the distribution. + +For documentation, the comprehensive links in the top-level file +\OnCD{doc.html} may be helpful. The documentation for nearly everything +(packages, formats, fonts, program manuals, man pages, Info files) is in +\dirname{texmf-dist/doc}. You can use the \cmdname{texdoc} program to +find documentation wherever it is located. + +This \TL\ documentation itself is in \dirname{texmf-dist/doc/texlive}, +available in several languages: + +\begin{itemize*} +\item{Czech/Slovak:} \OnCD{texmf-dist/doc/texlive/texlive-cz} +\item{German:} \OnCD{texmf-dist/doc/texlive/texlive-de} +\item{English:} \OnCD{texmf-dist/doc/texlive/texlive-en} +\item{French:} \OnCD{texmf-dist/doc/texlive/texlive-fr} +\item{Italian:} \OnCD{texmf-dist/doc/texlive/texlive-it} +\item{Polish:} \OnCD{texmf-dist/doc/texlive/texlive-pl} +\item{Russian:} \OnCD{texmf-dist/doc/texlive/texlive-ru} +\item{Serbian:} \OnCD{texmf-dist/doc/texlive/texlive-sr} +\item{Simplified Chinese:} \OnCD{texmf-dist/doc/texlive/texlive-zh-cn} +\end{itemize*} + +\subsection{Overview of the predefined texmf trees} +\label{sec:texmftrees} + +This section lists the predefined variables specifying the texmf trees +used by the system, and their intended purpose, and the default layout +of \TL{}. The command \texttt{tlmgr~conf} shows the values of these +variables, so that you can easily find out how they map to particular +directories in your installation. + +All of the trees, including the personal ones, should follow the \TeX\ +Directory Structure (\TDS, \url{http://tug.org/tds}), with all its +myriad subdirectories, or files may not be found. Section +\ref{sec:local-personal-macros} (\p.\pageref{sec:local-personal-macros}) +describes this in more detail. The order here is the reverse order in +which the trees are searched, that is, later trees in the list override +earlier ones. + +\begin{ttdescription} +\item [TEXMFDIST] The tree which holds nearly all of the files in the original + distribution---configuration files, scripts, packages, fonts, etc. + (The main exception are the per-platform executables, which are stored + in a sibling directory \code{bin/}.) +\item [TEXMFSYSVAR] The (site-wide) tree used by \verb+texconfig-sys+, + \verb+updmap-sys+ and \verb+fmtutil-sys+, and also by \verb+tlmgr+, to + store (cached) runtime data such as format files and generated map files. +\item [TEXMFSYSCONFIG] The (site-wide) tree used by the utilities + \verb+texconfig-sys+, \verb+updmap-sys+, and \verb+fmtutil-sys+ to + store modified configuration data. +\item [TEXMFLOCAL] The tree which administrators can use for system-wide + installation of additional or updated macros, fonts, etc. +\item [TEXMFHOME] The tree which users can use for their own individual + installations of additional or updated macros, fonts, etc. + The expansion of this variable dynamically adjusts for each user to + their own individual directory. +\item [TEXMFVAR] The (personal) tree used by \verb+texconfig+, + \verb+updmap+ and \verb+fmtutil+ to store (cached) runtime data such + as format files and generated map files. +\item [TEXMFCONFIG] The (personal) tree used by the utilities + \verb+texconfig+, \verb+updmap+, and \verb+fmtutil+ to store modified + configuration data. +\item [TEXMFCACHE] The tree(s) used by \ConTeXt\ MkIV and Lua\LaTeX\ + to store (cached) runtime data; defaults to \code{TEXMFSYSVAR}, + or (if that's not writable), \code{TEXMFVAR}. +\end{ttdescription} + +\noindent +The default layout is: +\begin{description} + \item[system-wide root] can span multiple \TL{} releases + (\texttt{/usr/local/texlive} by default on Unix): + \begin{ttdescription} + \item[2018] A previous release. + \item[2019] The current release. + \begin{ttdescription} + \item [bin] ~ + \begin{ttdescription} + \item [i386-linux] \GNU/Linux binaries (32-bit) + \item [...] + \item [x86\_64-darwin] \MacOSX\ binaries + \item [x86\_64-linux] \GNU/Linux binaries (64-bit) + \item [win32] Windows binaries + \end{ttdescription} + \item [texmf-dist\ \ ] \envname{TEXMFDIST} and \envname{TEXMFMAIN} + \item [texmf-var \ \ ] \envname{TEXMFSYSVAR}, \envname{TEXMFCACHE} + \item [texmf-config] \envname{TEXMFSYSCONFIG} + \end{ttdescription} + \item [texmf-local] \envname{TEXMFLOCAL}, intended to be + retained from release to release. + \end{ttdescription} + \item[user's home directory] (\texttt{\$HOME} or + \texttt{\%USERPROFILE\%}) + \begin{ttdescription} + \item[.texlive2018] Privately generated and configuration data + for a previous release. + \item[.texlive2019] Privately generated and configuration data + for the current release. + \begin{ttdescription} + \item [texmf-var\ \ \ ] \envname{TEXMFVAR}, \envname{TEXMFCACHE} + \item [texmf-config] \envname{TEXMFCONFIG} + \end{ttdescription} + \item[texmf] \envname{TEXMFHOME} Personal macros, etc. + \end{ttdescription} +\end{description} + + +\subsection{Extensions to \protect\TeX} +\label{sec:tex-extensions} + +Knuth's original \TeX{} itself is frozen, apart from rare bug fixes. It +is present in \TL\ as the program \prog{tex}, and will remain so +for the foreseeable future. \TL{} also contains several extended versions of +\TeX\ (also known as \TeX\ engines): + +\begin{description} + +\item [\eTeX] adds a set of new primitives +\label{text:etex} (related to macro expansion, character scanning, +classes of marks, additional debugging features, and more) and the +\TeXXeT{} extensions for bidirectional typesetting. In default mode, +\eTeX{} is 100\% compatible with ordinary \TeX. See +\OnCD{texmf-dist/doc/etex/base/etex_man.pdf}. + +\item [pdf\TeX] builds on the \eTeX\ extensions, adding support for +writing PDF output as well as \dvi{}, and many non-output-related +extensions. This is the program invoked for most formats, e.g., +\prog{etex}, \prog{latex}, \prog{pdflatex}. Its web site is +\url{http://www.pdftex.org/}. See +\OnCD{texmf-dist/doc/pdftex/manual/pdftex-a.pdf} for the manual, and +\OnCD{texmf-dist/doc/pdftex/manual/samplepdf/samplepdf.tex} for example +usage of some of its features. + +\item [Lua\TeX] is the designated successor of pdf\TeX, +and is mostly (but not entirely) backward-compatible. It is also +intended to be a functional superset of Aleph (see below), though +perfect compatibility is not intended. The incorporated Lua +interpreter (\url{http://www.lua.org/}) enables elegant solutions for +many thorny \TeX{} problems. When called as \filename{texlua}, it +functions as a standalone Lua interpreter, and is used as such +within \TL. Its web site is \url{http://www.luatex.org/}, and the +reference manual is \OnCD{texmf-dist/doc/luatex/base/luatex.pdf}. + +\item [\XeTeX] adds support for Unicode input and OpenType- and system +fonts, implemented using standard third-party libraries. See +\url{http://tug.org/xetex}. + +\item [\OMEGA\ (Omega)] is based on Unicode (16-bit characters), thus +supports working with almost all the world's scripts simultaneously. It +also supports so-called `\OMEGA{} Translation Processes' (OTPs), +for performing complex transformations on arbitrary input. Omega is no +longer included in \TL{} as a separate program; only Aleph is provided: + +\item [Aleph] combines the \OMEGA\ and \eTeX\ extensions. +See \OnCD{texmf-dist/doc/aleph/base}. + +\end{description} + + +\subsection{Other notable programs in \protect\TL} + +Here are a few other commonly-used programs included in \TL{}: + +\begin{cmddescription} + +\item [bibtex, biber] bibliography support. + +\item [makeindex, xindy] index support. + +\item [dvips] convert \dvi{} to \PS{}. + +\item [xdvi] \dvi{} previewer for the X Window System. + +\item [dviconcat, dviselect] cut and paste pages +from \dvi{} files. + +\item [dvipdfmx] convert \dvi{} to PDF, an alternative approach +to pdf\TeX\ (mentioned above). + +\item [psselect, psnup, \ldots] \PS{} utilities. + +\item [pdfjam, pdfjoin, \ldots] PDF utilities. + +\item [context, mtxrun] Con\TeX{}t and PDF processor. + +\item [htlatex, \ldots] \cmdname{tex4ht}: \AllTeX{} to HTML (and +XML and more) converter. + +\end{cmddescription} + + +\htmlanchor{installation} +\section{Installation} +\label{sec:install} + +\subsection{Starting the installer} +\label{sec:inst-start} + +To begin, get the \TK{} \DVD{} or download the \TL{} net installer. See +\url{http://tug.org/texlive/acquire.html} for more information and other +methods of getting the software. + +\begin{description} +\item [Net installer, .zip or .tar.gz:] Download from \CTAN, under +\dirname{systems/texlive/tlnet}; the url +\url{http://mirror.ctan.org/systems/texlive/tlnet} should redirect to a +nearby, up-to-date, mirror. You can retrieve either +\filename{install-tl.zip} which can be used under Unix and Windows, or +the considerably smaller \filename{install-unx.tar.gz} for Unix +only. After unpacking, \filename{install-tl} and +\filename{install-tl-windows.bat} will be in the \dirname{install-tl} +subdirectory. + +\item[Net installer, Windows .exe:] Download from \CTAN{} as above, +and double-click. This starts up a first-stage installer and unpacker; +see figure~\ref{fig:nsis}. It gives two choices: ``Install'' +and``Unpack only''. + +\item [\TeX{} Collection \DVD:] go to the \DVD's \dirname{texlive} +subdirectory. Under Windows, the installer normally starts automatically +when you insert the \DVD. You can get the \DVD\ by becoming a member of +a \TeX\ user group (highly recommended, +\url{http://tug.org/usergroups.html}), or purchasing it separately +(\url{http://tug.org/store}), or burning your own from the \ISO\ image. +You can also mount the \ISO\ directly on most systems. After installing +from \DVD\ or \ISO, if you want to get continuing updates from the +Internet, please see \ref{sec:dvd-install-net-updates}. + +\end{description} + +\begin{figure}[tb] +\tlpng{nsis_installer}{.6\linewidth} +\caption{First stage of Windows \code{.exe} installer}\label{fig:nsis} +\end{figure} + +The same installer program is run, whatever the source. The most +visible difference between the two is that with the net installer, what +you end up with is the packages that are currently available. This is +in contrast to the \DVD\ and \ISO\ images, which are not updated between +the major public releases. + +If you need to download through proxies, use a \filename{~/.wgetrc} file +or environment variables with the proxy settings for Wget +(\url{http://www.gnu.org/software/wget/manual/html_node/Proxies.html}), +or the equivalent for whatever download program you are using. This does +not matter if you are installing from the \DVD\ or \ISO\ image. + +The following sections explain installer start-up in more detail. + +\subsubsection{Unix} + +Below, \texttt{>} denotes the shell prompt; user input is +\Ucom{\texttt{bold}}. +The script \filename{install-tl} is a Perl script. The simplest way +to start it on a Unix-compatible system is as follows: +\begin{alltt} +> \Ucom{perl /path/to/installer/install-tl} +\end{alltt} +(Or you can invoke \Ucom{/path/to/installer/install-tl} if it stayed +executable, or \texttt{cd} to the directory first, etc.; we won't repeat +all the variations.) You may have to enlarge your terminal window so +that it shows the full text installer screen +(figure~\ref{fig:text-main}). + +To install in \GUI\ mode (figure~\ref{fig:advanced-lnx}), you'll need to +have Tcl/Tk installed. Given that, you can run: +\begin{alltt} +> \Ucom{perl install-tl -gui} +\end{alltt} + +The old \code{wizard} and \code{perltk}/\code{expert} options are still +available. These require the \dirname{Perl::Tk} module compiled with XFT +support, which is generally no problem with \GNU/Linux, but often is +with other systems. For a complete listing of the various options: +\begin{alltt} +> \Ucom{perl install-tl -help} +\end{alltt} + +\textbf{About Unix permissions:} Your \code{umask} at the time +of installation will be respected by the \TL{} installer. Therefore, if +you want your installation to be usable by users other than you, make +sure your setting is sufficiently permissive, for instance, \code{umask +002}. For more information about \code{umask}, consult your system +documentation. + +\textbf{Special considerations for Cygwin:} Unlike other +Unix-compatible systems, Cygwin does not by default include all of the +prerequisite programs needed by the \TL{} installer. See +section~\ref{sec:cygwin}. + + +\subsubsection{\MacOSX} +\label{sec:macosx} + +As mentioned in section~\ref{sec:tl-coll-dists}, a separate distribution +is prepared for \MacOSX, named Mac\TeX\ (\url{http://tug.org/mactex}). +We recommend using the native Mac\TeX\ installer instead of the \TL\ +installer on \MacOSX, because the native installer makes a few +Mac-specific adjustments, in particular to allow easily switching +between the various \TeX\ distributions for \MacOSX\ (Mac\TeX, Fink, +MacPorts, \ldots) using the so-called \TeX{}Dist data structure. + +Mac\TeX\ is firmly based on \TL, and the main \TeX\ trees and binaries +are precisely the same. It adds a few extra folders with Mac-specific +documentation and applications. + + +\subsubsection{Windows}\label{sec:wininst} + +If you are using the unpacked downloaded zip file, or the \DVD\ +installer failed to start automatically, double-click +\filename{install-tl-windows.bat}. + +You can also start the installer from the command-prompt. Below, +\texttt{>} denotes the prompt; user input is \Ucom{\texttt{bold}}. If +you are in the installer directory, run just: +\begin{alltt} +> \Ucom{install-tl-windows} +\end{alltt} + +Or you can invoke it with an absolute location, such as: +\begin{alltt} +> \Ucom{D:\bs{}texlive\bs{}install-tl-windows} +\end{alltt} +for the \TK\ \DVD, supposing that \dirname{D:} is the optical +drive. Figure~\ref{fig:basic-w32} displays the initial basic screen +of the \GUI\ installer, which is the default for Windows. + +To install in text mode, use: +\begin{alltt} +> \Ucom{install-tl-windows -no-gui} +\end{alltt} + +For a complete listing of the various options: +\begin{alltt} +> \Ucom{install-tl-windows -help} +\end{alltt} + +\begin{figure}[tb] +\begin{boxedverbatim} +Installing TeX Live 2019 from: ... +Platform: x86_64-linux => 'GNU/Linux on x86_64' +Distribution: inst (compressed) +Directory for temporary files: /tmp +... + Detected platform: GNU/Linux on Intel x86_64 + + binary platforms: 1 out of 16 + + set installation scheme: scheme-full + + customizing installation collections + 40 collections out of 41, disk space required: 5829 MB + + directories: + TEXDIR (the main TeX directory): + /usr/local/texlive/2019 + ... + + options: + [ ] use letter size instead of A4 by default + ... + + set up for portable installation + +Actions: + start installation to hard disk +

The following additional packages are +recommended: +\begin{itemize*} +\item \filename{fontconfig} [needed by \XeTeX\ and Lua\TeX] +\item \filename{ghostscript} [needed by various utilities] +\item \filename{libXaw7} [needed by \code{xdvi}] +\item \filename{ncurses} [provides the \code{clear} command used by the installer] +\end{itemize*} + + +\subsubsection{The text installer} + +Figure~\ref{fig:text-main} displays the main text mode screen under +Unix. The text installer is the default on Unix. + +This is only a command-line installer; there is no cursor support at +all. For instance, you cannot tab around checkboxes or input fields. +You just type something (case-sensitive) at the prompt and press the +Enter key, and then the entire terminal screen will be rewritten, with +adjusted content. + +The text installer interface is this primitive in order to make it run +on as many platforms as possible, even with a minimal Perl. + +\subsubsection{The graphical installer} +\label{sec:graphical-inst} + +The default graphical installer starts out simple, with just a +few options; see figure~\ref{fig:basic-w32}. It can be started with +\begin{alltt} +> \Ucom{install-tl -gui} +\end{alltt} +The Advanced button gives access to most of the options of the text +installer; see figure~\ref{fig:advanced-lnx}. + +\subsubsection{The legacy installers} + +The \texttt{perltk}/\texttt{expert} and \texttt{wizard} modes are +still available for systems with have Perl/Tk installed. These can +be specified with \texttt{-gui=perltk} and \texttt{-gui=wizard} +arguments respectively. + +\subsection{Running the installer} +\label{sec:runinstall} + +The installer is intended to be mostly self-explanatory, but following are a +few notes about the various options and submenus. + +\subsubsection{Binary systems menu (Unix only)} +\label{sec:binary} + +\begin{figure}[tb] +\begin{boxedverbatim} +Available platforms: +=============================================================================== + a [ ] Cygwin on Intel x86 (i386-cygwin) + b [ ] Cygwin on x86_64 (x86_64-cygwin) + c [ ] MacOSX current (10.12-) on x86_64 (x86_64-darwin) + d [ ] MacOSX legacy (10.6-) on x86_64 (x86_64-darwinlegacy) + e [ ] FreeBSD on x86_64 (amd64-freebsd) + f [ ] FreeBSD on Intel x86 (i386-freebsd) + g [ ] GNU/Linux on ARM64 (aarch64-linux) + h [ ] GNU/Linux on ARMhf (armhf-linux) + i [ ] GNU/Linux on Intel x86 (i386-linux) + j [X] GNU/Linux on x86_64 (x86_64-linux) + k [ ] GNU/Linux on x86_64 with musl (x86_64-linuxmusl) + l [ ] NetBSD on x86_64 (amd64-netbsd) + m [ ] NetBSD on Intel x86 (i386-netbsd) + o [ ] Solaris on Intel x86 (i386-solaris) + p [ ] Solaris on x86_64 (x86_64-solaris) + s [ ] Windows (win32) +\end{boxedverbatim} +\vskip-\baselineskip +\caption{Binaries menu}\label{fig:bin-text} +\end{figure} + +Figure~\ref{fig:bin-text} displays the text mode binaries menu. By +default, only the binaries for your current platform will be installed. +From this menu, you can select installation of binaries for other +platforms as well. This can be useful if you are sharing a \TeX\ +tree across a network of heterogeneous machines, or for a dual-boot +system. + +\subsubsection{Selecting what is to be installed} +\label{sec:components} + +\begin{figure}[tbh] +\begin{boxedverbatim} +Select scheme: +=============================================================================== + a [X] full scheme (everything) + b [ ] medium scheme (small + more packages and languages) + c [ ] small scheme (basic + xetex, metapost, a few languages) + d [ ] basic scheme (plain and latex) + e [ ] minimal scheme (plain only) + f [ ] ConTeXt scheme + g [ ] GUST TeX Live scheme + h [ ] infrastructure-only scheme (no TeX at all) + i [ ] teTeX scheme (more than medium, but nowhere near full) + j [ ] custom selection of collections +\end{boxedverbatim} +\vskip-\baselineskip +\caption{Scheme menu}\label{fig:scheme-text} +\end{figure} + +Figure~\ref{fig:scheme-text} displays the \TL\ scheme menu; from here, +you choose a ``scheme'', which is an overall set of package collections. +The default \optname{full} scheme installs everything available. This is +recommended, but you can also choose the \optname{basic} scheme for +just plain and \LaTeX, \optname{small} for a few more programs +(equivalent to the so-called Basic\TeX\ installation of Mac\TeX), +\optname{minimal} for testing purposes, and \optname{medium} or +\optname{teTeX} to get something in between. There are also various +specialized and country-specific schemes. + +\begin{figure}[tb] +\centering \tlpng{stdcoll}{.7\linewidth} +\caption{Collections menu}\label{fig:collections-gui} +\end{figure} + +You can refine your scheme selection with the `collections' menu +(figure~\ref{fig:collections-gui}, shown in \GUI\ mode for a change). + +Collections are one level more detailed than schemes\Dash in essence, a +scheme consists of several collections, a collection consists of one or +more packages, and a package (the lowest level grouping in \TL) contains +the actual \TeX\ macro files, font files, and so on. + +If you want more control than the collection menus provide, you can use +the \TeX\ Live Manager (\prog{tlmgr}) program after installation (see +section~\ref{sec:tlmgr}); using that, you can control the installation +at the package level. + +\subsubsection{Directories} +\label{sec:directories} + +The default layout is described in section~\ref{sec:texmftrees}, +\p.\pageref{sec:texmftrees}. The default installation directory is +\dirname{/usr/local/texlive/2019} on Unix and +|%SystemDrive%\texlive\2019| on Windows. This arrangement enables +having many parallel \TL\ installations, such as one for each release +(typically by year, as here), and you can switch between them merely by +altering your search path. + +That installation directory can be overridden by setting the so-called +\dirname{TEXDIR} in the installer. The \GUI\ screen for this and other +options is shown in figure~\ref{fig:advanced-lnx}. The most common reasons +to change it are either lacking enough disk space in that partition (the +full \TL\ needs several gigabytes), or lacking write permission for the +default location (you don't have to be root or administrator to install +\TL, but you do need write access to the target directory). + +The installation directories can also be changed by setting a variety of +environment variables before running the installer (most likely, +\envname{TEXLIVE\_INSTALL\_PREFIX} or +\envname{TEXLIVE\_INSTALL\_TEXDIR}); see the documentation from +|install-tl --help| (available online at +\url{http://tug.org/texlive/doc/install-tl.html}) for the full list and +more details. + +A reasonable alternative destination is a directory under your home, +especially if you will be the sole user. Use `|~|' to indicate this, as +in `|~/texlive/2019|'. + +We recommend including the year in the name, to enable keeping different +releases of \TL{} side by side. (You may wish to also maintain a +version-independent name, such as \dirname{/usr/local/texlive-cur}, via a +symbolic link, which you can then repoint after testing the new release.) + +Changing \dirname{TEXDIR} in the installer will also change +\dirname{TEXMFLOCAL}, \dirname{TEXMFSYSVAR} and +\dirname{TEXMFSYSCONFIG}. + +\dirname{TEXMFHOME} is the recommended location for personal macro files +or packages. The default value is |~/texmf| (|~/Library/texmf| on +Macs). In contrast to \dirname{TEXDIR}, here a |~| is preserved in the +newly-written configuration files, since it usefully refers to the home +directory of the user running \TeX. It expands to \dirname{$HOME} on +Unix and \verb|%USERPROFILE%| on Windows. Special redundant note: +\envname{TEXMFHOME}, like all trees, must be organized according to the +\TDS, or files may not be found. + +\dirname{TEXMFVAR} is the location for storing most cached runtime data +specific to each user. \dirname{TEXMFCACHE} is the variable name used +for that purpose by Lua\LaTeX and \ConTeXt\ MkIV (see +section~\ref{sec:context-mkiv}, \p.\pageref{sec:context-mkiv}); its +default value is \dirname{TEXMFSYSVAR}, or (if that's not writable), +\dirname{TEXMFVAR}. + + +\subsubsection{Options} +\label{sec:options} + +\begin{figure}[tbh] +\begin{boxedverbatim} +Options customization: +=============================================================================== +

use letter size instead of A4 by default: [ ] + execution of restricted list of programs: [X] + create all format files: [X] + install font/macro doc tree: [X] + install font/macro source tree: [X] + create symlinks in standard directories: [ ] + binaries to: + manpages to: + info to: + after install, set CTAN as source for package updates: [X] +\end{boxedverbatim} +\vskip-\baselineskip +\caption{Options menu (Unix)}\label{fig:options-text} +\end{figure} + +Figure~\ref{fig:options-text} shows the text mode options menu. +More info on each: + +\begin{description} +\item[use letter size instead of A4 by default:] The default paper + size selection. Of course, individual documents can and should + specify a specific paper size, if desired. + +\item[execution of restricted list of programs:] As of \TL\ 2010, + execution of a few external programs is allowed by default. The (very + short) list of allowed programs is given in the \filename{texmf.cnf}. + See the 2010 news (section~\ref{sec:2010news}) for more details. + +\item[create format files:] Although unnecessary format files + take time to generate and disk space to store, it is still recommended + to leave this option checked: if you don't, then format files will be + generated in people's private \dirname{TEXMFVAR} tree as they are + needed. In that location, they will not be updated automatically if + (say) binaries or hyphenation patterns are updated in the + installation, and thus you could end up with incompatible format files. + +\item[install font/macro \ldots\ tree:] Download/install the + documentation and source files included in most packages. Unchecking + is not recommended. + +\item[create symlinks in standard directories:] + This option (Unix only) bypasses the need to change environment + variables. Without this option, \TL{} directories usually have to be + added to \envname{PATH}, \envname{MANPATH} and \envname{INFOPATH}. You + will need write permissions to the target directories. This option is + intended for accessing the \TeX\ system through directories that are + already known to users, such as \dirname{/usr/local/bin}, which don't + already contain any \TeX\ files. Do not overwrite existing files on + your system with this option, e.g., by specifying system directories. + The safest and recommended approach is to leave the option unchecked. + +\item[after installation \ldots\ \CTAN:] When installing from \DVD, this + option is enabled by default, since usually one wants to take any + subsequent package updates from the \CTAN\ area that is updated + throughout the year. The only likely reason to disable it is if you + install only a subset from the \DVD\ and plan to augment the + installation later. In any case, the package repository for the + installer, and for updates after installation, can be set + independently as needed; see section~\ref{sec:location} and + section~\ref{sec:dvd-install-net-updates}. +\end{description} +Windows-specific options, as displayed in the advanced Perl/Tk +interface: +\begin{description} +\item[adjust PATH setting in registry] This ensures that all + programs will see the \TL{} binary directory on their search path. + +\item[add menu shortcuts] If set, there will be a \TL{} submenu of + the Start menu. There is a third option `Launcher entry' besides + `TeX Live menu' and `No shortcuts'. This option is described in + section \ref{sec:sharedinstall}. + +\item[change file associations] The options are `Only new' (create + file associations, but do not overwrite existing ones), `All' and + `None'. + +\item[install \TeX{}works front end] +\end{description} +When all the settings are to your liking, you can type `I' in the +text interface, or press the `Install TeX Live' button in the +Perl/Tk \GUI, to start the installation process. When it is done, +skip to section~\ref{sec:postinstall} to read what else needs to be +done, if anything. + +\subsection{Command-line install-tl options} +\label{sec:cmdline} + +Type +\begin{alltt} +> \Ucom{install-tl -help} +\end{alltt} +for a listing of command-line options. Either |-| or |--| can be used +to introduce option names. These are the most common ones: + +\begin{ttdescription} +\item[-gui] Use the \GUI{} installer if possible. This requires + Tcl/Tk version 8.5 or higher. This is the case on \MacOSX\ and is + distributed with \TL{} on Windows. The legacy options + \texttt{-gui=perltk} and \texttt{-gui=wizard} are still available + and require the Perl/Tk module + (\url{http://tug.org/texlive/distro.html#perltk}) compiled with + XFT support; if Tcl/Tk and Perl/Tk are not available, installation + continues in text mode. + +\item[-no-gui] Force using the text mode installer. + +\item[-lang {\sl LL}] Specify the installer interface + language as a standard (usually two-letter) code. The installer tries + to automatically determine the right language but if it fails, or if + the right language is not available, then it uses English as a + fallback. Run \verb|install-tl --help| to get the list of available + languages. + +\item[-portable] Install for portable use on, e.g., a \USB{} stick. + Also selectable from within the text installer with the \code{V} + command, and from the \GUI{} installer. See + section~\ref{sec:portable-tl}. + +\item[-profile {\sl file}] Load the installation profile \var{file} and + do the installation with no user interaction. The installer always + writes a file \filename{texlive.profile} to the \dirname{tlpkg} + subdirectory of your installation. That file can be given as the + argument to redo the exact same installation on a different system, + for example. Alternatively, you can use a custom profile, most easily + created by starting from a generated one and changing values, or an + empty file, which will take all the defaults. + +\item [-repository {\sl url-or-directory}] Specify package + repository from which to install; see following. + +\htmlanchor{opt-in-place} +\item[-in-place] (Documented only for completeness: Do not use this + unless you know what you are doing.) If you already have an rsync, svn, + or other copy of \TL{} (see + \url{http://tug.org/texlive/acquire-mirror.html}) then this option + will use what you've got, as-is, and do only the necessary + post-install. Be warned that the file \filename{tlpkg/texlive.tlpdb} + may be overwritten; saving it is your responsibility. Also, package + removal has to be done manually. This option cannot be toggled via the + installer interface. +\end{ttdescription} + + +\subsubsection{The \optname{-repository} option} +\label{sec:location} + +The default network package repository is a \CTAN{} mirror chosen +automatically via \url{http://mirror.ctan.org}. + +If you want to override that, the location value can be a url starting +with \texttt{ftp:}, \texttt{http:}, or \texttt{file:/}, or a plain +directory path. (When giving an \texttt{http:}\ or \texttt{ftp:}\ +location, trailing `\texttt{/}' characters and/or a trailing +`\texttt{/tlpkg}' component are ignored.) + +For example, you could choose a particular \CTAN\ mirror with something +like: \url{http://ctan.example.org/tex-archive/systems/texlive/tlnet/}, +substituting a real hostname and its particular top-level \CTAN\ path +for |ctan.example.org/tex-archive|. The list of \CTAN\ mirrors is +maintained at \url{http://ctan.org/mirrors}. + +If the given argument is local (either a path or a \texttt{file:/} url), +compressed files in an \dirname{archive} subdirectory of the repository +path are used (even if uncompressed files are available as well). + + +\subsection{Post-install actions} +\label{sec:postinstall} + +Some post-installation may be required. + +\subsubsection{Environment variables for Unix} +\label{sec:env} + +If you elected to create symlinks in standard directories (described in +section~\ref{sec:options}), then there is no need to edit environment +variables. Otherwise, on Unix systems, the directory of the binaries +for your platform must be added to the search path. (On Windows, the +installer takes care of this.) + +Each supported platform has its own subdirectory under +\dirname{TEXDIR/bin}. See figure~\ref{fig:bin-text} for the list of +subdirectories and corresponding platforms. + +Optionally, you can also add the documentation man and Info directories +to their respective search paths, if you want the system tools to find +them. The man pages might be found automatically after the addition to +\envname{PATH}. + +For Bourne-compatible shells such as \prog{bash}, and using Intel x86 +GNU/Linux and a default directory setup as an example, the file to edit +might be \filename{$HOME/.profile} (or another file sourced by +\filename{.profile}, and the lines to add would look like this: + +\begin{sverbatim} +PATH=/usr/local/texlive/2019/bin/x86_64-linux:$PATH; export PATH +MANPATH=/usr/local/texlive/2019/texmf-dist/doc/man:$MANPATH; export MANPATH +INFOPATH=/usr/local/texlive/2019/texmf-dist/doc/info:$INFOPATH; export INFOPATH +\end{sverbatim} + +For csh or tcsh, the file to edit is typically \filename{$HOME/.cshrc}, and +the lines to add might look like: + +\begin{sverbatim} +setenv PATH /usr/local/texlive/2019/bin/x86_64-linux:$PATH +setenv MANPATH /usr/local/texlive/2019/texmf-dist/doc/man:$MANPATH +setenv INFOPATH /usr/local/texlive/2019/texmf-dist/doc/info:$INFOPATH +\end{sverbatim} + +If you already have settings somewhere in your ``dot'' files, naturally +the \TL\ directories should be merged in as appropriate. + + +\subsubsection{Environment variables: Global configuration} +\label{sec:envglobal} + +If you want to make these changes globally, or for a user newly added to +the system, then you are on your own; there is just too much variation +between systems in how and where these things are configured. + +Our two hints are: 1)~you may want to check for a file +\filename{/etc/manpath.config} and, if present, add lines such as + +\begin{sverbatim} +MANPATH_MAP /usr/local/texlive/2019/bin/x86_64-linux \ + /usr/local/texlive/2019/texmf-dist/doc/man +\end{sverbatim} + +And 2)~check for a file \filename{/etc/environment} which may define the +search path and other default environment variables. + +In each (Unix) binary directory, we also create a symbolic link named +\code{man} to the directory \dirname{texmf-dist/doc/man}. Some \code{man} +programs, such as the standard \MacOSX\ \code{man}, will automatically +find that, obviating the need for any man page setup. + + +\subsubsection{Internet updates after \DVD\ installation} +\label{sec:dvd-install-net-updates} + +If you installed \TL\ from \DVD\ and then wish to get updates from the +Internet, you need to run this command---\emph{after} you've updated +your search path (as described in the previous section): + +\begin{alltt} +> \Ucom{tlmgr option repository http://mirror.ctan.org/systems/texlive/tlnet} +\end{alltt} + +This tells \cmdname{tlmgr} to use a nearby \CTAN\ mirror for future updates. +This is done by default when installing from \DVD, via the option +described in section~\ref{sec:options}. + +If there are problems with the automatic mirror selection, you can +specify a particular \CTAN\ mirror from the list at +\url{http://ctan.org/mirrors}. Use the exact path to the +\dirname{tlnet} subdir on that mirror, as shown above. + + +\htmlanchor{xetexfontconfig} % keep historical anchor working +\htmlanchor{sysfontconfig} +\subsubsection{System font configuration for \protect\XeTeX\protect\ and Lua\protect\TeX} +\label{sec:font-conf-sys} + +\XeTeX\ and Lua\TeX\ can use any font installed on the system, not just +those in the \TeX\ trees. They do these via related but not identical +methods. + +On Windows, fonts shipped with \TL\ are automatically made available to +\XeTeX\ by font name. On \MacOSX, supporting font name lookups requires +additional steps; please see the Mac\TeX\ web pages +(\url{http://tug.org/mactex}). For other Unix systems, the procedure to +be able to find the fonts shipped with \TL\ via font name follows. + +To facilitate this, when the \pkgname{xetex} package is installed +(either at initial installation or later), the necessary configuration +file is created in +\filename{TEXMFSYSVAR/fonts/conf/texlive-fontconfig.conf}. + +To set up the \TL{} fonts for system-wide use (assuming you have +suitable privileges), proceed as follows: +\begin{enumerate*} +\item Copy the \filename{texlive-fontconfig.conf} file to +\dirname{/etc/fonts/conf.d/09-texlive.conf}. +\item Run \Ucom{fc-cache -fsv}. +\end{enumerate*} + +If you do not have sufficient privileges to carry out the steps above, +or if you want to make the \TL{} fonts available to only one user, +you can do the following: +\begin{enumerate*} +\item Copy the \filename{texlive-fontconfig.conf} file to + \filename{~/.fonts.conf}, where \filename{~} is your home directory. +\item Run \Ucom{fc-cache -fv}. +\end{enumerate*} + +You can run \code{fc-list} to see the names of the system fonts. The +incantation \code{fc-list : family style file spacing} (all arguments +are literal strings) shows some generally interesting information. + + +\subsubsection{\protect\ConTeXt{} Mark IV} +\label{sec:context-mkiv} + +Both the `old' \ConTeXt{} (Mark II) and the `new' \ConTeXt{} +(Mark IV) should run out of the box after \TL{} installation, +and should need no special attention as long as you stick to +using \verb+tlmgr+ for updates. + +However, because \ConTeXt{} MkIV does not use the kpathsea +library, some setup will be required whenever you install new +files manually (without using \verb+tlmgr+). After each such +installation, each MkIV user must run: +\begin{sverbatim} +context --generate +\end{sverbatim} +to refresh the \ConTeXt{} disk cache data. +The resulting files are stored under \code{TEXMFCACHE}, +whose default value in \TL\ is \verb+TEXMFSYSVAR;TEXMFVAR+. + +\ConTeXt\ MkIV will read from +all paths mentioned in \verb+TEXMFCACHE+, and write to the first +path that is writable. While reading, the last found match will +take precedence in the case of duplicated cache data. + +For more information, see +\url{http://wiki.contextgarden.net/Running_Mark_IV}. + + +\subsubsection{Integrating local and personal macros} +\label{sec:local-personal-macros} + +This is already mentioned implicitly in section~\ref{sec:texmftrees}: +\dirname{TEXMFLOCAL} (by default, +\dirname{/usr/local/texlive/texmf-local} or +\verb|%SystemDrive%\texlive\texmf-local| on Windows) +is intended for system-wide local fonts and macros; and +\dirname{TEXMFHOME} (by default, \dirname{$HOME/texmf} or +\verb|%USERPROFILE%\texmf|), is for personal fonts and macros. These +directories are intended to stick around from release to release, and +have their content seen automatically by a new \TL{} release. +Therefore, it is best to refrain from changing the definition of +\dirname{TEXMFLOCAL} to be too far away from the main \TL{} directory, +or you will need to manually change future releases. + +For both trees, files should be placed in their proper \TeX\ Directory +Structure (\TDS) subdirectories; see \url{http://tug.org/tds} or consult +\filename{texmf-dist/web2c/texmf.cnf}. For instance, a \LaTeX{} class file or +package should be placed in \dirname{TEXMFLOCAL/tex/latex} or +\dirname{TEXMFHOME/tex/latex}, or a subdirectory thereof. + +\dirname{TEXMFLOCAL} requires an up-to-date filename database, or files +will not be found. You can update it with the command +\cmdname{mktexlsr} or use the `Reinit file database' button on the +configuration tab of the \TeX\ Live Manager \GUI. + +By default, each of these variables is defined to be a single directory, +as shown. This is not a hard-and-fast requirement. If you need to +easily switch back and forth between different versions of large +packages, for example, you can maintain multiple trees for your own +purposes. This is done by setting \dirname{TEXMFHOME} to the +list of directories, within braces, separated by commas: + +\begin{verbatim} + TEXMFHOME = {/my/dir1,/mydir2,/a/third/dir} +\end{verbatim} + +Section~\ref{sec:brace-expansion} describes brace expansion further. + + +\subsubsection{Integrating third-party fonts} + +This is unfortunately a messy topic. Forget about it unless you want to +delve into many details of the \TeX{} installation. Many fonts are +included in \TL\ already, so take a look if you don't already know +that what you want isn't there. + +A possible alternative is to use \XeTeX\ or Lua\TeX\ (see +section~\ref{sec:tex-extensions}), which let you use operating system +fonts without any installation in \TeX. + +If you do need to do this, see +\url{http://tug.org/fonts/fontinstall.html} for our best effort at +describing the procedure. + + +\subsection{Testing the installation} +\label{sec:test-install} + +After installing \TL{}, you naturally want to test it out, so you can +start creating beautiful documents and\slash or fonts. + +One thing you may immediately be looking for is a front-end with which +to edit files. \TL{} installs \TeX{}works +(\url{http://tug.org/texworks}) on Windows (only), and Mac\TeX\ installs +TeXShop (\url{http://pages.uoregon.edu/koch/texshop}. On other Unix +systems, it's left up to you to choose an editor. There are many +choices available, some of which are listed in the next section; see +also \url{http://tug.org/interest.html#editors}. Any plain text editor +will work; something \TeX-specific is not required. + +The rest of this section gives some basic procedures for testing that +the new system is functional. We give Unix commands here; under +\MacOSX{} and Windows, you're more likely to run the tests through a +graphical interface, but the principles are the same. + +\begin{enumerate} + +\item Make sure that you can run the \cmdname{tex} program in the first +place: +\begin{alltt} +> \Ucom{tex -{}-version} +TeX 3.14159265 (TeX Live ...) +Copyright ... D.E. Knuth. +... +\end{alltt} +If this comes back with `command not found' instead of version and +copyright information, or with an older version, most likely you don't +have the correct \dirname{bin} subdirectory in your \envname{PATH}. See +the environment-setting information on \p.\pageref{sec:env}. + +\item Process a basic \LaTeX{} file: +\begin{alltt} +> \Ucom{latex sample2e.tex} +This is pdfTeX 3.14... +... +Output written on sample2e.dvi (3 pages, 7484 bytes). +Transcript written on sample2e.log. +\end{alltt} +If this fails to find \filename{sample2e.tex} or other files, most +likely you have interference from old environment variables or +configuration files; we recommend unsetting all \TeX-related environment +variables for a start. (For a deep analysis, you can ask \TeX{} to +report on exactly what it is searching for, and finding; see ``Debugging +actions'' on page~\pageref{sec:debugging}.) + +\item Preview the result online: +\begin{alltt} +> \Ucom{xdvi sample2e.dvi} # Unix +> \Ucom{dviout sample2e.dvi} # Windows +\end{alltt} +You should see a new window with a nice document explaining some of the +basics of \LaTeX{}. (Well worth reading, by the way, if you're new to +\TeX.) You do have to be running under X for \cmdname{xdvi} to work; if +you're not, or your \envname{DISPLAY} environment variable is set +incorrectly, you'll get an error \samp{Can't open display}. + +\item Create a \PS{} file for printing or display: +\begin{alltt} +> \Ucom{dvips sample2e.dvi -o sample2e.ps} +\end{alltt} + +\item Create a PDF file instead of \dvi{}; this processes the +\filename{.tex} file and writes PDF directly: +\begin{alltt} +> \Ucom{pdflatex sample2e.tex} +\end{alltt} + +\item Preview the PDF file: +\begin{alltt} +> \Ucom{gv sample2e.pdf} +\textrm{or:} +> \Ucom{xpdf sample2e.pdf} +\end{alltt} +Neither \cmdname{gv} nor \cmdname{xpdf} are included in \TL{}, so +you must install them separately.

Here we +turn to some specialized cases. + +\htmlanchor{tlsharedinstall} +\subsection{Shared-user (or cross-machine) installations} +\label{sec:sharedinstall} + +\TL{} has been designed to be shared between different systems on a +network. With a standard directory layout, no hard paths are +configured: the locations for files needed by \TL{} programs are +found relative to the programs. You can see this in the principal +configuration file +\filename{$TEXMFDIST/web2c/texmf.cnf}, which contains lines such as +\begin{sverbatim} +TEXMFROOT = $SELFAUTOPARENT +... +TEXMFDIST = $TEXMFROOT/texmf-dist +... +TEXMFLOCAL = $SELFAUTOGRANDPARENT/texmf-local +\end{sverbatim} +This means that adding the directory for \TL{} executables for their +platform to their search path is sufficient to get a working setup. + +By the same token, you can also install \TL{} locally and then move +the entire hierarchy afterwards to a network location. + +For Windows, \TL{} includes a launcher \filename{tlaunch}. Its main +window contains menu entries and buttons for various \TeX-related +programs and documentation, customizable via an \code{ini} file. On +first use, it replicates the usual Windows-specific post-install, +\emph{i.e.}, search path modification and file associations, but only +for the current user. Therefore, workstations with access to \TL{} on +the local network only need a menu shortcut for the launcher. See the +\code{tlaunch} manual (\code{texdoc tlaunch}, or +\url{https://ctan.org/pkg/tlaunch}). + + +\htmlanchor{tlportable} +\subsection{Portable (\USB{}) installations} +\label{sec:portable-tl} + +The \code{-portable} installer option (or \code{V} command in the text +installer or corresponding \GUI{} option) creates a completely +self-contained \TL{} installation under a common root and forgoes system +integration. You can create such an installation directly on a \USB{} +stick, or copy it to a \USB{} stick afterwards. + +To run \TeX\ using this portable installation, you need to add the +appropriate binary directory to the search path during your terminal +session, as usual. + +On Windows, you can double-click \filename{tl-tray-menu} at the root +of the installation and create a temporary `tray menu' offering a +choice of a few common tasks, as shown in this screenshot: + +\medskip +\tlpng{tray-menu}{4cm} +\smallskip + +\noindent The `More\ldots' entry explains how you can customize this menu. + + +%\htmlanchor{tlisoinstall} +%\subsection{\ISO\ (or \DVD) installations} +%\label{sec:isoinstall} +% +%If you don't need to update or otherwise modify your installation often, +%and\slash or have several systems on which to use \TL{}, it may be +%convenient to create an \ISO\ of your \TL{} installation, because: +% +%\begin{itemize} +%\item Copying an \ISO\ between different computers is much +% faster than copying a normal installation. +%\item If you are dual-booting between different operating systems +% and want them to share a \TL{} installation, an \ISO +% installation is not tied to the idiosyncrasies and limitations of +% other mutually supported filesystems (FAT32, NTFS, +% HFS+). +%\item Virtual machines can simply mount such an \ISO. +%\end{itemize} +% +%Of course you can also burn an \ISO\ to \DVD, if that is useful for you. +% +%Desktop \GNU/Linux/Unix systems, including \MacOSX, are able to +%mount an \ISO. Windows 8 is the first(!) Windows version which can +%do this. Apart from that, nothing changes compared to a normal hard +%disk installation, see section \ref{sec:env}. +% +%When preparing such an \ISO\ installation, it is best to omit the +%subdirectory for the release year, and have +%\filename{texmf-local} at the same level as the other trees +%(\filename{texmf-dist}, \filename{texmf-var}, etc.). You can do this with +%the normal directory options in the installer. +% +%For a physical (rather than virtual) Windows system, you can burn +%the \ISO\ to DVD. However, it may be worth your while to +%investigate free \ISO-mounting options such as WinCDEmu at +%\url{http://wincdemu.sysprogs.org/}. +% +%For Windows system integration, you can include the \filename{w32client} +%scripts described in section~\ref{sec:sharedinstall} and at +%\url{http://tug.org/texlive/w32client.html}, which work just as well for +%an \ISO\ as for a network installation. +% +%On \MacOSX, TeXShop will be able to use the DVD +%installation if a symlink \filename{/usr/texbin} points to the +%appropriate binary directory, e.g., +%\begin{verbatim} +%sudo ln -s /Volumes/MyTeXLive/bin/universal-darwin /usr/texbin +%\end{verbatim} +% +%Historical note: \TL{} 2010 was the first \TL{} edition which was no +%longer distributed `live'. However, it always required some acrobatics +%to run from \DVD\ or \ISO; in particular, there was no way around +%setting at least one extra environment variable. If you create your +%\ISO\ from an existing installation then there is no need for this. + + +\htmlanchor{tlmgr} +\section{\cmdname{tlmgr}: Managing your installation} +\label{sec:tlmgr} + +\begin{figure}[tb] +\tlpng{tlshell-macos}{\linewidth} +\caption{\prog{tlshell} \GUI, showing the Actions menu (\MacOSX)} +\label{fig:tlshell} +\end{figure} + +\begin{figure}[tb] +\tlpng{tlcockpit-packages}{.8\linewidth} +\caption{\prog{tlcockpit} \GUI{} for \prog{tlmgr}} +\label{fig:tlcockpit} +\end{figure} + +\begin{figure}[tb] +\tlpng{tlmgr-gui}{\linewidth} +\caption{Legacy \prog{tlmgr} \GUI\ mode: main window, after `Load'} +\label{fig:tlmgr-gui} +\end{figure} + +\TL{} includes a program named \prog{tlmgr} for managing \TL{} after the +initial installation. Its capabilities include: + +\begin{itemize*} +\item installing, updating, backing up, restoring, and uninstalling + individual packages, optionally taking dependencies into account; +\item searching for and listing packages and their descriptions; +\item listing, adding, and removing platforms; +\item changing installation options such as paper size and source + location (see section~\ref{sec:location}). +\end{itemize*} + +\prog{tlmgr}'s functionality completely subsumes the \prog{texconfig} +program. We still distribute and maintain \prog{texconfig} for the sake +of anyone used to its interface, but we recommend using \prog{tlmgr} +nowadays. + +\subsection{Current \GUI{} interfaces for \cmdname{tlmgr}} + +\TL{} contains several \GUI s for +\prog{tlmgr}. Figure~\ref{fig:tlshell} shows \cmdname{tlshell}, +which is written in Tcl/Tk and works out of the box under Windows +and \MacOSX. Figure~\ref{fig:tlcockpit} shows \prog{tlcockpit}, +which requires Java version~8 or higher and JavaFX. Both are +separate packages. + +\prog{tlmgr} itself can also be run in \GUI{} mode +(figure~\ref{fig:tlmgr-gui}) with +\begin{alltt} +> \Ucom{tlmgr -gui} +\end{alltt} +This \GUI\ extension requires Perl/Tk, which module is no longer +included in \TL's Perl distribution for Windows. + +\subsection{Sample \cmdname{tlmgr} command-line invocations} + +After the initial installation, you can update your system to the latest +versions available with: +\begin{alltt} +> \Ucom{tlmgr update -all} +\end{alltt} +If this makes you nervous, first try +\begin{alltt} +> \Ucom{tlmgr update -all -dry-run} +\end{alltt} +or (less verbose): +\begin{alltt} +> \Ucom{tlmgr update -list} +\end{alltt} + +This more complex example adds a collection, for the engine \XeTeX, from +a local directory: + +\begin{alltt} +> \Ucom{tlmgr -repository /local/mirror/tlnet install collection-xetex} +\end{alltt} +It generates the following output (abridged): +\begin{fverbatim} +install: collection-xetex +install: arabxetex +... +install: xetex +install: xetexconfig +install: xetex.i386-linux +running post install action for xetex +install: xetex-def +... +running mktexlsr +mktexlsr: Updating /usr/local/texlive/2019/texmf-dist/ls-R... +... +running fmtutil-sys --missing +... +Transcript written on xelatex.log. +fmtutil: /usr/local/texlive/2019/texmf-var/web2c/xetex/xelatex.fmt installed. +\end{fverbatim} + +As you can see, \prog{tlmgr} installs dependencies, and takes care of any +necessary post-install actions, including updating the filename database +and (re)generating formats. In the above, we generated new formats for +\XeTeX. + +To describe a package (or collection or scheme): +\begin{alltt} +> \Ucom{tlmgr show collection-latexextra} +\end{alltt} +which produces output like this: +\begin{fverbatim} +package: collection-latexextra +category: Collection +shortdesc: LaTeX supplementary packages +longdesc: A very large collection of add-on packages for LaTeX. +installed: Yes +revision: 46963 +sizes: 657941k +\end{fverbatim} + +Last and most important, for full documentation see +\url{http://tug.org/texlive/tlmgr.html}, or: +\begin{alltt} +> \Ucom{tlmgr -help} +\end{alltt} + + +\section{Notes on Windows} +\label{sec:windows} + +\subsection{Windows-specific features} +\label{sec:winfeatures} + +Under Windows, the installer does some extra things: +\begin{description} +\item[Menus and shortcuts.] A new `\TL{}' submenu of the + Start menu is installed, which contains entries for some \GUI{} + programs (\prog{tlmgr}, \prog{texdoctk}, the PS\_View (\prog{psv}) + PostScript previewer) and some documentation. +\item[File associations.] If enabled, \prog{TeXworks}, \prog{Dviout} + and \prog{PS\_view} become either the default program for + their respective filetypes, or get an entry in the `Open with' + right-click menus of those filetypes. +\item[Bitmap to eps converter.] Various bitmapped formats get an + entry \cmdname{bitmap2eps} in their `Open with' right-click + menu. Bitmap2eps is a simple script which lets \cmdname{sam2p} or + \cmdname{bmeps} do the real work. +\item[Automatic path adjustment.] No manual configuration steps are required. +\item[Uninstaller.] The installer creates an entry under `Add/Remove + Programs' for \TL. The uninstall tab of the \TeX\ Live Manager \GUI\ + refers to this. For a single-user install, the installer also + creates an uninstall entry under the Start menu. +\item[Write-protect.] For an admin install, the \TL\ directories are + write-protected, at least if \TL\ is installed on a normal + NTFS-formatted non-removable disk. +\end{description} + +Also, have a look at \filename{tlaunch}, described in +section~\ref{sec:sharedinstall}, for a different approach. + +\subsection{Additional software included on Windows} + +To be complete, a \TL{} installation needs support packages that are not +commonly found on a Windows machine. \TL{} provides the missing pieces. +These programs are all installed as part of \TL{} only on Windows. + +\begin{description} +\item[Perl and Ghostscript.] Because of the importance of Perl and + Ghostscript, \TL{} includes `hidden' copies of these + programs. \TL{} programs that need them know where to find them, + but they don't betray their presence through environment variables + or registry settings. They aren't full-scale installations, and + shouldn't interfere with any system installations of Perl or + Ghostscript. + +\item[PS\_View.] Also installed is PS\_View, a \PS{} and PDF + viewer; see figure~\ref{fig:psview}. + +\begin{figure}[tb] +\centering \tlpng{psview}{.6\linewidth} +\caption{PS\_View: very high magnifications available!}\label{fig:psview} +\end{figure} + +\item[dviout.] Also installed is \prog{dviout}, a DVI viewer. + At first, when you preview files with \cmdname{dviout}, it will create + fonts, because screen fonts were not installed. After a while, you + will have created most of the fonts you use, and you will rarely see + the font-creation window. More information can be found in the + (highly recommended) on-line help. + +\item[\TeX{}works.] \TeX{}works is a \TeX-oriented editor with + an integrated PDF viewer. + +\item[Command-line tools.] A number of Windows ports of common Unix + command-line programs are installed along with the usual \TL{} + binaries. These include \cmdname{gzip}, \cmdname{zip}, + \cmdname{unzip}, and the utilities from the \cmdname{poppler} suite + (\cmdname{pdfinfo}, \cmdname{pdffonts}, \ldots); no standalone PDF + viewer for Windows is included. One option for that is the Sumatra + PDF viewer, available from \url{https://sumatrapdfreader.org/}. + +\item[fc-list, fc-cache, \ldots] The tools from the fontconfig library allow + \XeTeX{} to handle system fonts on Windows. You can use + \prog{fc-list} to determine the font names to pass to \XeTeX's + extended \cs{font} command. If necessary, run \prog{fc-cache} + first to update font information. + +\end{description} + + +\subsection{User Profile is Home} +\label{sec:winhome} + +The Windows counterpart of a Unix home directory is the +\verb|%USERPROFILE%| directory. Under Windows Vista and later it is +\verb|C:\Users\|. In the +\filename{texmf.cnf} file, and \KPS{} in general, \verb|~| will +expand appropriately on both Windows and Unix. + + +\subsection{The Windows registry} +\label{sec:registry} + +Windows stores nearly all configuration data in its registry. The +registry contains a set of hierarchically organized keys, with several +root keys. The most important ones for installation programs are +\path{HKEY_CURRENT_USER} and \path{HKEY_LOCAL_MACHINE}, \path{HKCU} and +\path{HKLM} in short. The \path{HKCU} part of the registry is in the +user's home directory (see section~\ref{sec:winhome}). \path{HKLM} is +normally in a subdirectory of the Windows directory. + +In some cases, system information could be obtained from environment +variables but for other information, for example the location of +shortcuts, it is necessary to consult the registry. Setting environment +variables permanently also requires registry access. + + +\subsection{Windows permissions} +\label{sec:winpermissions} + +In later versions of Windows, a distinction is made between regular +users and administrators, where only the latter have free access to the +entire operating system. We have made an effort to make \TL{} +installable without administrative privileges. + +If the installer is started with administrative permissions, there is an +option to install for all users. If this option is chosen, shortcuts +are created for all users, and the system search path is +modified. Otherwise, shortcuts and menu entries are created for the +current user, and the user search path is modified. + +Regardless of administrator status, the default root of \TL{} proposed +by the installer is always under \verb|%SystemDrive%|. The installer +always tests whether the root is writable for the current user. + +A problem may arise if the user is not an administrator and \TeX{} +already exists in the search path. Since the effective search path +consists of the system search path followed by the user search path, the +new \TL{} would never get precedence. As a safeguard, the installer +creates a shortcut to the command-prompt in which the new \TL{} binary +directory is prepended to the local search path. The new \TL{} will be +always usable from within such a command-prompt. The shortcut for +\TeX{}works, if installed, also prepends \TL{} to the search path, so it +should also be immune to this path problem. + +You should be aware that even if you are logged in as administrator, you +need to explicitly ask for administrator privileges. In fact, there is +not much point in logging in as administrator. Instead, right-clicking +on the program or shortcut that you want to run usually gives you a +choice `Run as administrator'. + + +\subsection{Increasing maximum memory on Windows and Cygwin} +\label{sec:cygwin-maxmem} + +Windows and Cygwin (see section~\ref{sec:cygwin} for Cygwin installation +specifics) users may find that they run out of memory when running some +of the programs shipped with \TL. For example, \prog{asy} might run out +of memory if you try to allocate an array of 25,000,000 reals, and +Lua\TeX\ might run out of memory if you try to process a document with a +lot of big fonts. + +For Cygwin, you can increase the amount of available memory by following +the instructions in the Cygwin User's Guide +(\url{http://www.cygwin.com/cygwin-ug-net/setup-maxmem.html}). + +For Windows, you have to create a file, say \code{moremem.reg}, with +these four lines: + +\begin{sverbatim} +Windows Registry Editor Version 5.00 + +[HKEY_LOCAL_MACHINE\Software\Cygwin] +"heap_chunk_in_mb"=dword:ffffff00 +\end{sverbatim} + +\noindent and then execute the command \code{regedit /s moremem.reg} as +administrator. (If you want to change memory only for the current user +instead of system-wide, use \code{HKEY\_CURRENT\_USER}.) + + +\section{A user's guide to Web2C} + +\Webc{} is an integrated collection of \TeX-related programs: \TeX{} +itself, \MF{}, \MP, \BibTeX{}, etc. It is the heart of \TL{}. The home +page for \Webc{}, with the current manual and more, is +\url{http://tug.org/web2c}. + +A bit of history: The original implementation was by Tomas Rokicki who, +in 1987, developed a first \TeX{}-to-C system based on change files +under Unix, which were primarily the original work of Howard Trickey and +Pavel Curtis. Tim Morgan became the maintainer of the system, and +during this period the name changed to Web-to-C\@. In 1990, Karl Berry +took over the work, assisted by dozens of additional contributors, and +in 1997 he handed the baton to Olaf Weber, who returned it to Karl in +2006. + +The \Webc{} system runs on Unix, 32-bit Windows systems, \MacOSX{}, and +other operating systems. It uses Knuth's original sources for \TeX{} and +other basic programs written in the \web{} literate programming system +and translates them into C source code. The core \TeX{} programs +handled in this way are: + +\begin{cmddescription} +\item[bibtex] Maintaining bibliographies. +\item[dvicopy] Expands virtual font references in \dvi{} files. +\item[dvitomp] \dvi{} to MPX (MetaPost pictures). +\item[dvitype] \dvi{} to human-readable text. +\item[gftodvi] Generic font proofsheets. +\item[gftopk] Generic to packed fonts. +\item[gftype] GF to human-readable text. +\item[mf] Creating typeface families. +\item[mft] Prettyprinting \MF{} source. +\item[mpost] Creating technical diagrams. +\item[patgen] Creating hyphenation patterns. +\item[pktogf] Packed to generic fonts. +\item[pktype] PK to human-readable text. +\item[pltotf] Plain text property list to TFM. +\item[pooltype] Display \web{} pool files. +\item[tangle] \web{} to Pascal. +\item[tex] Typesetting. +\item[tftopl] TFM to plain text property list. +\item[vftovp] Virtual font to virtual property list. +\item[vptovf] Virtual property list to virtual font. +\item[weave] \web{} to \TeX. +\end{cmddescription} + +\noindent The precise functions and syntax of these programs are +described in the documentation of the individual packages and of \Webc{} +itself. However, knowing a few principles governing the whole family of +programs will help you take advantage of your \Webc{} installation. + +All programs honor these standard \GNU options: +\begin{ttdescription} +\item[-{}-help] print basic usage summary. +\item[-{}-verbose] print detailed progress report. +\item[-{}-version] print version information, then exit. +\end{ttdescription} + +For locating files the \Webc{} programs use the path searching library +\KPS{} (\url{http://tug.org/kpathsea}). This library uses a combination +of environment variables and configuration files to optimize searching +the (huge) collection of \TeX{} files. \Webc{} can look at many +directory trees simultaneously, which is useful in maintaining \TeX's +standard distribution and local and personal extensions in distinct +trees. To speed up file searches, the root of each tree has a file +\file{ls-R}, containing an entry showing the name and relative pathname +for all files under that root. + + +\subsection{Kpathsea path searching} +\label{sec:kpathsea} + +Let us first describe the generic path searching mechanism of the \KPS{} +library. + +We call a \emph{search path} a colon- or semicolon\hyph sepa\-rated list +of \emph{path elements}, which are basically directory names. A +search path can come from (a combination of) many sources. To look up +a file \samp{my-file} along a path \samp{.:/dir}, \KPS{} checks each +element of the path in turn: first \file{./my-file}, then +\file{/dir/my-file}, returning the first match (or possibly all +matches). + +In order to adapt optimally to all operating systems' conventions, on +non-Unix systems \KPS{} can use filename separators different from +colon (\samp{:}) and slash (\samp{/}). + +To check a particular path element \var{p}, \KPS{} first checks if a +prebuilt database (see ``Filename data\-base'' on +page~\pageref{sec:filename-database}) applies to \var{p}, i.e., if the +database is in a directory that is a prefix of \var{p}. If so, the path +specification is matched against the contents of the database. + +Although the simplest and most common path element is a directory +name, \KPS{} supports additional features in search paths: layered +default values, environment variable names, config file values, users' +home directories, and recursive subdirectory searching. Thus, we say +that \KPS{} \emph{expands} a path element, meaning it transforms all +the specifications into basic directory name or names. This is +described in the following sections in the same order as it takes +place. + +Note that if the filename being searched for is absolute or explicitly +relative, i.e., starts with \samp{/} or \samp{./} or \samp{../}, +\KPS{} simply checks if that file exists. + +\ifSingleColumn +\else +\begin{figure*} +\verbatiminput{examples/ex5.tex} +\setlength{\abovecaptionskip}{0pt} + \caption{An illustrative configuration file sample} + \label{fig:config-sample} +\end{figure*} +\fi + +\subsubsection{Path sources} +\label{sec:path-sources} + +A search path can come from many sources. In the order in which +\KPS{} uses them: + +\begin{enumerate} +\item + A user-set environment variable, for instance, \envname{TEXINPUTS}\@. + Environment variables with a period and a program name appended + override; e.g., if \samp{latex} is the name of the program being run, + then \envname{TEXINPUTS.latex} will override \envname{TEXINPUTS}. +\item + A program-specific configuration file, for exam\-ple, a line + \samp{S /a:/b} in \cmdname{dvips}'s \file{config.ps}. +\item A \KPS{} configuration file \file{texmf.cnf}, containing a line like + \samp{TEXINPUTS=/c:/d} (see below). +\item The compile-time default. +\end{enumerate} +\noindent You can see each of these values for a given search path by +using the debugging options (see ``Debugging actions'' on +page~\pageref{sec:debugging}). + +\subsubsection{Config files} + +\KPS{} reads \emph{runtime configuration files} named \file{texmf.cnf} +for search path and other definitions. The search path used to look +for these files is named \envname{TEXMFCNF}, but we do not recommend +setting this (or any) environment variable. + +Instead, normal installation results in a file +\file{.../2019/texmf.cnf}. If you must make changes to the defaults +(not normally necessary), this is the place to put them. The main +configuration file is in \file{.../2019/texmf-dist/web2c/texmf.cnf}. +You should not edit this latter file, as your changes will be lost when +the distributed version is updated. + +\emph{All} \file{texmf.cnf} files in the search path will be read and +definitions in earlier files override those in later files. For +example, with a search path of \verb|.:$TEXMF|, values from +\file{./texmf.cnf} override those from \verb|$TEXMF/texmf.cnf|. + +\begin{itemize*} +\item + Comments start with \code{\%} and continue to the end of the line. +\item + Blank lines are ignored. +\item + A \bs{} at the end of a line acts as a continuation character, + i.e., the next line is appended. Whitespace at the beginning of + continuation lines is not ignored. +\item + Each remaining line has the form: +\begin{alltt} + \var{variable}[.\var{progname}] [=] \var{value} +\end{alltt}% + where the \samp{=} and surrounding whitespace are optional. +\item + The \ttvar{variable} name may contain any character other + than whitespace, \samp{=}, or \samp{.}, but sticking to + \samp{A-Za-z\_} is safest. +\item + If \samp{.\var{progname}} is present, the definition only + applies if the program that is running is named + \texttt{\var{progname}} or \texttt{\var{progname}.exe}. This allows + different flavors of \TeX{} to have different search paths, for + example. +\item \var{value} may contain any characters except + \code{\%} and \samp{@}. The + \code{\$\var{var}.\var{prog}} feature is not available on the + right-hand side; instead, you must use an additional variable. A + \samp{;}\ in \var{value} is translated to \samp{:}\ if + running under Unix; this is useful to be able to have a single + \file{texmf.cnf} for Unix, MS-DOS and Windows systems. +\item + All definitions are read before anything is expanded, so + variables can be referenced before they are defined. +\end{itemize*} +A configuration file fragment illustrating most of these points is +\ifSingleColumn +shown below: + +\verbatiminput{examples/ex5.tex} +\else +shown in figure~\ref{fig:config-sample}. +\fi + +\subsubsection{Path expansion} +\label{sec:path-expansion} + + +\KPS{} recognizes certain special characters and constructions in +search paths, similar to those available in Unix shells. As a +general example, the complex path, +\verb+~$USER/{foo,bar}//baz+, expands to all subdirectories under +directories \file{foo} and \file{bar} in \texttt{\$USER}'s home +directory that contain a directory or file \file{baz}. These +expansions are explained in the sections below. +%$ +\subsubsection{Default expansion} +\label{sec:default-expansion} + +If the highest-priority search path (see ``Path sources'' on +page~\pageref{sec:path-sources}) contains an \emph{extra colon} (i.e., +leading, trailing, or doubled), \KPS{} inserts at that point the +next-highest-prio\-rity search path that is defined. If that inserted +path has an extra colon, the same happens with the next highest. For +example, given an environment variable setting + +\begin{alltt} +> \Ucom{setenv TEXINPUTS /home/karl:} +\end{alltt} +and a \code{TEXINPUTS} value from \file{texmf.cnf} of + +\begin{alltt} + .:\$TEXMF//tex +\end{alltt} +then the final value used for searching will be: + +\begin{alltt} + /home/karl:.:\$TEXMF//tex +\end{alltt} + +Since it would be useless to insert the default value in more than one +place, \KPS{} changes only one extra \samp{:}\ and leaves any others in +place. It checks first for a leading \samp{:}, then a trailing +\samp{:}, then a doubled \samp{:}. + +\subsubsection{Brace expansion} +\label{sec:brace-expansion} + +A useful feature is brace expansion, which means that, for instance, +\verb+v{a,b}w+ expands to \verb+vaw:vbw+. Nesting is allowed. +This is used to implement multiple \TeX{} hierarchies, by +assigning a brace list to \code{\$TEXMF}. +For example, in \file{texmf.cnf}, a definition like this +(simplified for this example) is made: +\begin{verbatim} + TEXMF = {$TEXMFVAR,$TEXMFHOME,!!$TEXMFLOCAL,!!$TEXMFDIST} +\end{verbatim} +We can then use this to define, for example, the \TeX\ input path: +\begin{verbatim} + TEXINPUTS = .;$TEXMF/tex// +\end{verbatim} +%$ +which means that, after looking in the current directory, the +\code{\$TEXMFVAR/tex}, \code{\$TEXMFHOME/tex}, \code{\$TEXMFLOCAL/tex} +and \code{\$TEXMFDIST/tex} trees \emph{only}) will be searched (the +last two using \file{ls-R} data base files). It is a convenient +way for running two parallel \TeX{} structures, one ``frozen'' (on a +\CD, for instance) and the other being continuously updated with new +versions as they become available. By using the \code{\$TEXMF} +variable in all definitions, one is sure to always search the +up-to-date tree first. + +\subsubsection{Subdirectory expansion} +\label{sec:subdirectory-expansion} + +Two or more consecutive slashes in a path element following a directory +\var{d} is replaced by all subdirectories of \var{d}: first those +subdirectories directly under \var{d}, then the subsubdirectories under +those, and so on. At each level, the order in which the directories are +searched is \emph{unspecified}. + +If you specify any filename components after the \samp{//}, only +subdirectories with matching components are included. For example, +\samp{/a//b} expands into directories \file{/a/1/b}, \file{/a/2/b}, +\file{/a/1/1/b}, and so on, but not \file{/a/b/c} or \file{/a/1}. + +Multiple \samp{//} constructs in a path are possible, but +\samp{//} at the beginning of a path is ignored. + +\subsubsection{List of special characters and their meaning: a summary} + +The following list summarizes the special characters in \KPS{} +configuration files. + +% need a wider space for the item labels here. +\newcommand{\CODE}[1]{\makebox[3em][l]{\code{#1}}} +\begin{ttdescription} +\item[\CODE{:}] Separator in path specification; at the beginning or + the end of a path it substitutes the default path expansion.\par +\item[\CODE{;}] Separator on non-Unix systems (acts like \code{:}). +\item[\CODE{\$}] Variable expansion. +\item[\CODE{\string~}] Represents the user's home directory. +\item[\CODE{\char`\{...\char`\}}] Brace expansion. +\item[\CODE{//}] Subdirectory expansion (can occur anywhere in + a path, except at its beginning). +\item[\CODE{\%}] Start of comment. +\item[\CODE{\bs}] Continuation character (allows multi-line entries). +\item[\CODE{!!}] Search \emph{only} database to locate file, \emph{do + not} search the disk. +\end{ttdescription} + + +\subsection{Filename databases} +\label{sec:filename-database} + +\KPS{} goes to some lengths to minimize disk accesses for searches. +Nevertheless, at installations with enough directories, searching each +possible directory for a given file can take an excessively long time +(this is especially true if many hundreds of font directories have to +be traversed.) Therefore, \KPS{} can use an externally-built plain text +``database'' file named \file{ls-R} that maps files to directories, +thus avoiding the need to exhaustively search the disk. + +A second database file \file{aliases} allows you to give additional +names to the files listed in \file{ls-R}. This can be helpful to +confirm to DOS 8.3 filename conventions in source files. + +\subsubsection{The filename database} +\label{sec:ls-R} + +As explained above, the name of the main filename database must be +\file{ls-R}. You can put one at the root of each \TeX{} hierarchy in +your installation that you wish to be searched (\code{\$TEXMF} by +default). \KPS{} looks for +\file{ls-R} files along the \code{TEXMFDBS} path. + +The recommended way to create and maintain \samp{ls-R} is to run the +\code{mktexlsr} script included with the distribution. It is invoked +by the various \samp{mktex}\dots\ scripts. In principle, this script +just runs the command +\begin{alltt} +cd \var{/your/texmf/root} && \path|\|ls -1LAR ./ >ls-R +\end{alltt} +presuming your system's \code{ls} produces the right output format +(\GNU \code{ls} is all right). To ensure that the database is +always up-to-date, it is easiest to rebuild it regularly via +\code{cron}, so that it is automatically updated when the installed +files change, such as after installing or updating a \LaTeX{} package. + +If a file is not found in the database, by default \KPS{} goes ahead +and searches the disk. If a particular path element begins with +\samp{!!}, however, \emph{only} the database will be searched for that +element, never the disk. + + +\subsubsection{kpsewhich: Standalone path searching} +\label{sec:invoking-kpsewhich} + +The \texttt{kpsewhich} program exercises path searching independent of any +particular application. This can be useful as a sort of \code{find} +program to locate files in \TeX{} hierarchies (this is used heavily in +the distributed \samp{mktex}\dots\ scripts). + +\begin{alltt} +> \Ucom{kpsewhich \var{option}\dots{} \var{filename}\dots{}} +\end{alltt} +The options specified in \ttvar{option} start with either \samp{-} +or \samp{-{}-}, and any unambiguous abbreviation is accepted. + +\KPS{} looks up each non-option argument on the command line as a +filename, and returns the first file found. There is no option to +return all the files with a particular name (you can run the Unix +\samp{find} utility for that). + +The most common options are described next. + +\begin{ttdescription} +\item[\texttt{-{}-dpi=\var{num}}]\mbox{} + Set the resolution to \ttvar{num}; this only affects \samp{gf} + and \samp{pk} lookups. \samp{-D} is a synonym, for compatibility + with \cmdname{dvips}. Default is 600. + +\item[\texttt{-{}-format=\var{name}}]\mbox{}\\ + Set the format for lookup to \ttvar{name}. By default, the + format is guessed from the filename. For formats which do not have + an associated unambiguous suffix, such as \MP{} support files and + \cmdname{dvips} configuration files, you have to specify the name as + known to \KPS{}, such as \texttt{tex} or \texttt{enc files}. Run + \texttt{kpsewhich -{}-help} for a list. + +\item[\texttt{-{}-mode=\var{string}}]\mbox{}\\ + Set the mode name to \ttvar{string}; this only affects \samp{gf} + and \samp{pk} lookups. No default: any mode will be found. +\item[\texttt{-{}-must-exist}]\mbox{}\\ + Do everything possible to find the files, notably including + searching the disk. By default, only the \file{ls-R} database is + checked, in the interest of efficiency. +\item[\texttt{-{}-path=\var{string}}]\mbox{}\\ + Search along the path \ttvar{string} (colon-separated as usual), + instead of guessing the search path from the filename. \samp{//} and + all the usual expansions are supported. The options \samp{-{}-path} + and \samp{-{}-format} are mutually exclusive. +\item[\texttt{-{}-progname=\var{name}}]\mbox{}\\ + Set the program name to \texttt{\var{name}}. + This can affect the search paths via the \texttt{.\var{progname}} + feature. + The default is \cmdname{kpsewhich}. +\item[\texttt{-{}-show-path=\var{name}}]\mbox{}\\ + shows the path used for file lookups of file type \texttt{\var{name}}. + Either a filename extension (\code{.pk}, \code{.vf}, etc.) or a + name can be used, just as with \samp{-{}-format} option. +\item[\texttt{-{}-debug=\var{num}}]\mbox{}\\ + sets the debugging options to \texttt{\var{num}}. +\end{ttdescription} + + +\subsubsection{Examples of use} +\label{sec:examples-of-use} + +Let us now have a look at \KPS{} in action. Here's a straightforward search: + +\begin{alltt} +> \Ucom{kpsewhich article.cls} + /usr/local/texmf-dist/tex/latex/base/article.cls +\end{alltt} +We are looking for the file \file{article.cls}. Since the \samp{.cls} +suffix is unambiguous we do not need to specify that we want to look for a +file of type \optname{tex} (\TeX{} source file directories). We find it in +the subdirectory \file{tex/latex/base} below the \samp{texmf-dist} \TL\ +directory. Similarly, all of the following are found without problems +thanks to their unambiguous suffix. +\begin{alltt} +> \Ucom{kpsewhich array.sty} + /usr/local/texmf-dist/tex/latex/tools/array.sty +> \Ucom{kpsewhich latin1.def} + /usr/local/texmf-dist/tex/latex/base/latin1.def +> \Ucom{kpsewhich size10.clo} + /usr/local/texmf-dist/tex/latex/base/size10.clo +> \Ucom{kpsewhich small2e.tex} + /usr/local/texmf-dist/tex/latex/base/small2e.tex +> \Ucom{kpsewhich tugboat.bib} + /usr/local/texmf-dist/bibtex/bib/beebe/tugboat.bib +\end{alltt} + +By the way, that last is a \BibTeX{} bibliography database for +\textsl{TUGboat} articles. + +\begin{alltt} +> \Ucom{kpsewhich cmr10.pk} +\end{alltt} +Font bitmap glyph files of type \file{.pk} are used by display +programs like \cmdname{dvips} and \cmdname{xdvi}. Nothing is returned in +this case since there are no pre-generated Computer Modern \samp{.pk} +files in \TL{}\Dash the Type~1 variants are used by default. +\begin{alltt} +> \Ucom{kpsewhich wsuipa10.pk} +\ifSingleColumn /usr/local/texmf-var/fonts/pk/ljfour/public/wsuipa/wsuipa10.600pk +\else /usr/local/texmf-var/fonts/pk/ljfour/public/ +... wsuipa/wsuipa10.600pk +\fi\end{alltt} +For these fonts (a phonetic alphabet from the University of Washington) +we had to generate \samp{.pk} files, and since the default \MF{} mode on +our installation is \texttt{ljfour} with a base resolution of 600\dpi{} +(dots per inch), this instantiation is returned. +\begin{alltt} +> \Ucom{kpsewhich -dpi=300 wsuipa10.pk} +\end{alltt} +In this case, when specifying that we are interested in a resolution +of 300\dpi{} (\texttt{-dpi=300}) we see that no such font is available on +the system. A program like \cmdname{dvips} or \cmdname{xdvi} would +go off and actually build the required \texttt{.pk} files +using the script \cmdname{mktexpk}. + +Next we turn our attention to \cmdname{dvips}'s header and configuration +files. We first look at one of the commonly used files, the general +prologue \file{tex.pro} for \TeX{} support, before turning our attention +to the generic configuration file (\file{config.ps}) and the \PS{} font +map \file{psfonts.map}\Dash as of 2004, map and encoding files have +their own search paths and new location in \dirname{texmf} trees. As +the \samp{.ps} suffix is ambiguous we have to specify explicitly which +type we are considering (\optname{dvips config}) for the file +\texttt{config.ps}. +\begin{alltt} +> \Ucom{kpsewhich tex.pro} + /usr/local/texmf/dvips/base/tex.pro +> \Ucom{kpsewhich --format="dvips config" config.ps} + /usr/local/texmf/dvips/config/config.ps +> \Ucom{kpsewhich psfonts.map} + /usr/local/texmf/fonts/map/dvips/updmap/psfonts.map +\end{alltt} + +We now take a closer look at the URW Times \PS{} support +files. The prefix for these in the standard font naming scheme is +\samp{utm}. The first file we look at is the configuration file, +which contains the name of the map file: +\begin{alltt} +> \Ucom{kpsewhich --format="dvips config" config.utm} + /usr/local/texmf-dist/dvips/psnfss/config.utm +\end{alltt} +The contents of that file is +\begin{alltt} + p +utm.map +\end{alltt} +which points to the file \file{utm.map}, which we want to +locate next. +\begin{alltt} +> \Ucom{kpsewhich utm.map} + /usr/local/texmf-dist/fonts/map/dvips/times/utm.map +\end{alltt} +This map file defines the file names of the Type~1 \PS{} fonts in +the URW collection. Its contents look like (we only show part of the +lines): +\begin{alltt} +utmb8r NimbusRomNo9L-Medi ... \Ucom{kpsewhich utmr8a.pfb} +\ifSingleColumn /usr/local/texmf-dist/fonts/type1/urw/times/utmr8a.pfb +\else /usr/local/texmf-dist/fonts/type1/ +... urw/utm/utmr8a.pfb +\fi\end{alltt} + +It should be evident from these examples how you can easily locate the +whereabouts of a given file. This is especially important if you suspect +that the wrong version of a file is picked up somehow, since +\cmdname{kpsewhich} will show you the first file encountered. + +\subsubsection{Debugging actions} +\label{sec:debugging} + +Sometimes it is necessary to investigate how a program resolves file +references. To make this practical, \KPS{} offers various levels of +debugging output: + +\begin{ttdescription} +\item[\texttt{\ 1}] \texttt{stat} calls (disk lookups). When running + with an up-to-date \file{ls-R} database this should almost give no + output. +\item[\texttt{\ 2}] References to hash tables (such as \file{ls-R} + databases, map files, configuration files). +\item[\texttt{\ 4}] File open and close operations. +\item[\texttt{\ 8}] General path information for file types + searched by \KPS. This is useful to find out where a particular + path for the file was defined. +\item[\texttt{16}] Directory list for each path element (only relevant + for searches on disk). +\item[\texttt{32}] File searches. +\item[\texttt{64}] Variable values. +\end{ttdescription} +A value of \texttt{-1} will set all the above options; in practice, +this is usually the most convenient. + +Similarly, with the \cmdname{dvips} program, by setting a combination of +debug switches, one can follow in detail where files are being picked up +from. Alternatively, when a file is not found, the debug trace shows in +which directories the program looks for the given file, so that one can +get an indication what the problem~is. + +Generally speaking, as most programs call the \KPS{} library +internally, one can select a debug option by using the +\envname{KPATHSEA\_DEBUG} environment variable, and setting it to (a +combination of) values as described in the above list. + +(Note for Windows users: it is not easy to redirect +all messages to a file in this system. For diagnostic purposes +you can temporarily \texttt{SET KPATHSEA\_DEBUG\_OUTPUT=err.log}). + +Let us consider, as an example, a small \LaTeX{} source file, +\file{hello-world.tex}, which contains the following input. +\begin{verbatim} + \documentclass{article} + \begin{document} + Hello World! + \end{document} +\end{verbatim} +This little file only uses the font \file{cmr10}, so let us look at +how \cmdname{dvips} prepares the \PS{} file (we want to use the Type~1 +version of the Computer Modern fonts, hence the option \texttt{-Pcms}). +\begin{alltt} +> \Ucom{dvips -d4100 hello-world -Pcms -o} +\end{alltt} +In this case we have combined \cmdname{dvips}'s debug class 4 (font +paths) with \KPS's path element expansion (see the \cmdname{dvips} +reference manual). +The output (slightly rearranged) appears in +Figure~\ref{fig:dvipsdbga}. +\begin{figure*}[tp] +\centering +\input{examples/ex6a.tex} +\caption{Finding configuration files}\label{fig:dvipsdbga} +\end{figure*} + +\cmdname{dvips} starts by locating its working files. First, +\file{texmf.cnf} is found, which gives the definitions of the search +paths for the other files, then the file database \file{ls-R} (to +optimize file searching) and the file \file{aliases}, which makes it +possible to declare several names (e.g., a short DOS-like 8.3 and +a more natural longer version) for the same file. Then \cmdname{dvips} +goes on to find the generic configuration file \file{config.ps} +before looking for the customization file \file{.dvipsrc} (which, in +this case is \emph{not found}). Finally, \cmdname{dvips} locates the +config file for the Computer Modern \PS{} fonts \file{config.cms} +(this was initiated with the \texttt{-Pcms} option on the \cmdname{dvips} +command). This file contains the list of the map files which +define the relation between the \TeX{}, \PS{} and file system +names of the fonts. +\begin{alltt} +> \Ucom{more /usr/local/texmf/dvips/cms/config.cms} + p +ams.map + p +cms.map + p +cmbkm.map + p +amsbkm.map +\end{alltt} +\cmdname{dvips} thus goes on to find all these files, plus the generic +map file \file{psfonts.map}, which is always loaded (it contains +declarations for commonly used \PS{} fonts; see the last part of +section~\ref{sec:examples-of-use} for more details about \PS{} map +file handling). + +At this point \cmdname{dvips} identifies itself to the user: +\begin{alltt} +This is dvips(k) 5.92b Copyright 2002 Radical Eye Software (www.radicaleye.com) +\end{alltt} +\ifSingleColumn +Then it goes on to look for the prolog file \file{texc.pro}: +\begin{alltt}\small +kdebug:start search(file=texc.pro, must\_exist=0, find\_all=0, + path=.:~/tex/dvips//:!!/usr/local/texmf/dvips//: + ~/tex/fonts/type1//:!!/usr/local/texmf/fonts/type1//). +kdebug:search(texc.pro) => /usr/local/texmf/dvips/base/texc.pro +\end{alltt} +\else +Then it goes on to look for the prolog file \file{texc.pro} (see +Figure~\ref{fig:dvipsdbgb}). +\fi + +After having found the file in question, \cmdname{dvips} outputs +the date and time, and informs us that it will generate the +file \file{hello-world.ps}, then that it needs the font file +\file{cmr10}, and that the latter is declared as ``resident'' (no +bitmaps needed): +\begin{alltt}\small +TeX output 1998.02.26:1204' -> hello-world.ps +Defining font () cmr10 at 10.0pt +Font cmr10 is resident. +\end{alltt} +Now the search is on for the file \file{cmr10.tfm}, which is found, +then a few more prolog files (not shown) are referenced, and finally +the Type~1 instance \file{cmr10.pfb} of the font is located and +included in the output file (see last line). +\begin{alltt}\small +kdebug:start search(file=cmr10.tfm, must\_exist=1, find\_all=0, + path=.:~/tex/fonts/tfm//:!!/usr/local/texmf/fonts/tfm//: + /var/tex/fonts/tfm//). +kdebug:search(cmr10.tfm) => /usr/local/texmf/fonts/tfm/public/cm/cmr10.tfm +kdebug:start search(file=texps.pro, must\_exist=0, find\_all=0, + ... + +kdebug:start search(file=cmr10.pfb, must\_exist=0, find\_all=0, + path=.:~/tex/dvips//:!!/usr/local/texmf/dvips//: + ~/tex/fonts/type1//:!!/usr/local/texmf/fonts/type1//). +kdebug:search(cmr10.pfb) => /usr/local/texmf/fonts/type1/public/cm/cmr10.pfb +[1] +\end{alltt} + +\subsection{Runtime options} + +Another useful feature of \Webc{} is its possibility to control a number +of memory parameters (in particular, array sizes) via the runtime file +\file{texmf.cnf} read by \KPS{}. The memory settings can be found in +Part~3 of that file in the \TL{} distribution. The more important +are: + +\begin{ttdescription} +\item[\texttt{main\_memory}] + Total words of memory available, for + \TeX{}, \MF{} and \MP. You must make a new format file for each + different setting. For instance, you could generate a ``huge'' + version of \TeX{}, and call the format file \texttt{hugetex.fmt}. + Using the standard way of specifying the program name used by \KPS{}, + the particular value of the \texttt{main\_memory} variable will then + be read from \file{texmf.cnf}. +\item[\texttt{extra\_mem\_bot}] + Extra space for ``large'' \TeX{} data structures: + boxes, glue, breakpoints, etc. Especially useful if you use + \PiCTeX{}. +\item[\texttt{font\_mem\_size}] + Number of words for font information available for \TeX. This + is more or less the total size of all TFM files read. +\item[\texttt{hash\_extra}] + Additional space for the hash table of control sequence names. + Only $\approx$10,000 control sequences can be stored in the main + hash table; if you have a large book with numerous cross-references, + this might not be enough. The default value of + \texttt{hash\_extra} is \texttt{50000}. +\end{ttdescription} + +\noindent Of course, this facility is no substitute for truly dynamic +arrays and memory allocation, but since these are extremely difficult to +implement in the present \TeX{} source, these runtime parameters provide +a practical compromise allowing some flexibility. + + +\begin{comment} +\section{Building on a new Unix platform} + +If you have a platform for which executables are not included, you will +need to compile \TeX{} and friends. This is not as hard as it +sounds. What you need is all in the directory \texttt{source} in the +distribution. + +\subsection{Prerequisites} + +You will need at least 100 megabytes of disk space to compile all of +\TeX{} and its support programs.

The \TL{} documentation web page +is \url{http://tug.org/texlive/doc.html}. + +Of course the most important acknowledgement must go to Donald Knuth, +first for inventing \TeX, and then for giving it to the world. + + +\section{Release history} +\label{sec:history} + +\subsection{Past} + +Discussion began in late 1993 when the Dutch \TeX{} Users Group was +starting work on its 4All\TeX{} \CD{} for MS-DOS users, and it +was hoped at that time to issue a single, rational, \CD{} for all +systems. This was too ambitious a target for the time, but it did spawn +not only the very successful 4All\TeX{} \CD{}, but also the TUG +Technical Council working group on a \emph{\TeX{} Directory Structure} +(\url{http://tug.org/tds}), which specified how to create consistent and +manageable collections of \TeX{} support files. A complete draft of the +\TDS{} was published in the December 1995 issue of \textsl{TUGboat}, and +it was clear from an early stage that one desirable product would be a +model structure on \CD{}. The distribution you now have is a very direct +result of the working group's deliberations. It was also clear that the +success of the 4All\TeX{} \CD{} showed that Unix users would benefit +from a similarly easy system, and this is the other main strand of +\TL. + +We first undertook to make a new Unix-based \TDS{} \CD{} in the autumn +of 1995, and quickly identified Thomas Esser's \teTeX{} as the ideal +setup, as it already had multi-platform support and was built with +portability across file systems in mind. Thomas agreed to help, and work +began seriously at the start of 1996. The first edition was released in +May 1996. At the start of 1997, Karl Berry completed a major new release +of Web2c, which included nearly all the features which Thomas Esser had +added in \teTeX, and we decided to base the 2nd edition of the \CD{} on +the standard \Webc, with the addition of \teTeX's \texttt{texconfig} +script. The 3rd edition of the \CD{} was based on a major revision of +\Webc, 7.2, by Olaf Weber; at the same time, a new revision of \teTeX +was being made, and \TL{} included almost all of its features. The +4th edition followed the same pattern, using a new version of \teTeX, +and a new release of \Webc{} (7.3). The system now included a complete +Windows setup, thanks to Fabrice Popineau. + +For the 5th edition (March 2000) many parts of the \CD{} were revised +and checked, updating hundreds of packages. Package details were stored +in XML files. But the major change for \TeX\ Live 5 was that all +non-free software was removed. Everything in \TL{} is now intended +to be compatible with the Debian Free Software Guidelines +(\url{http://www.debian.org/intro/free}); we have done our best to check +the license conditions of all packages, but we would very much +appreciate hearing of any mistakes. + +The 6th edition (July 2001) had much more material updated. The major +change was a new install concept: the user could select a more exact set +of needed collections. Language-related collections were completely +reorganized, so selecting any of them installs not only macros, fonts, +etc., but also prepares an appropriate \texttt{language.dat}. + +The 7th edition of 2002 had the notable addition of \MacOSX{} support, +and the usual myriad of updates to all sorts of packages and +programs. An important goal was integration of the source back with +\teTeX, to correct the drift apart in versions~5 and~6. + +\subsubsection{2003} + +In 2003, with the continuing flood of updates and additions, we found +that \TL{} had grown so large it could no longer be contained on a +single \CD, so we split it into three different distributions (see +section~\ref{sec:tl-coll-dists}, \p.\pageref{sec:tl-coll-dists}). In +addition: + +\begin{itemize*} +\item At the request of the \LaTeX{} team, we changed the standard + \cmdname{latex} and \cmdname{pdflatex} commands to now use \eTeX{} (see + \p.\pageref{text:etex}). +\item The new Latin Modern fonts were included (and are recommended). +\item Support for Alpha OSF was removed + (HPUX support was removed previously), since no one had (or + volunteered) hardware available on which to compile new binaries. +\item Windows setup was substantially changed; for the first time + an integrated environment based on XEmacs was introduced. +\item Important supplementary programs for Windows + (Perl, Ghost\-script, Image\-Magick, Ispell) are now installed + in the \TL{} installation directory. +\item Font map files used by \cmdname{dvips}, \cmdname{dvipdfm} + and \cmdname{pdftex} are now generated by the new program + \cmdname{updmap} and installed into \dirname{texmf/fonts/map}. +\item \TeX{}, \MF{}, and \MP{} now, by default, output most input + characters (32 and above) as themselves in output (e.g., + \verb|\write|) files, + log files, and the terminal, i.e., \emph{not} translated using the + \verb|^^| notation. In \TL{}~7, this translation was + dependent on the system locale settings; now, locale settings do + not influence the \TeX{} programs' behavior. If for some reason + you need the \verb|^^| output, rename the file + \verb|texmf/web2c/cp8bit.tcx|. (Future releases will have cleaner + ways to control this.) +\item This documentation was substantially revised. +\item Finally, since the edition numbers had grown unwieldy, + the version is now simply identified by the year: \TL{} 2003. +\end{itemize*} + + +\subsubsection{2004} + +2004 saw many changes: + +\begin{itemize} + +\item If you have locally-installed fonts which use their own +\filename{.map} or (much less likely) \filename{.enc} support files, you +may need to move those support files. + +\filename{.map} files are now searched for in subdirectories of +\dirname{fonts/map} only (in each \filename{texmf} tree), along the +\envname{TEXFONTMAPS} path. Similarly, \filename{.enc} files are now +searched for in subdirectories of \dirname{fonts/enc} only, along the +\envname{ENCFONTS} path. \cmdname{updmap} will attempt to warn about +problematic files. + +For methods of handling this and other information, please see +\url{http://tug.org/texlive/mapenc.html}. + +\item The \TK\ has been expanded with the addition of a \MIKTEX-based +installable \CD, for those who prefer that implementation to Web2C. +See section~\ref{sec:overview-tl} (\p.\pageref{sec:overview-tl}). + +\item Within \TL, the single large \dirname{texmf} tree of previous +releases has been replaced by three: \dirname{texmf}, +\dirname{texmf-dist}, and \dirname{texmf-doc}. See +section~\ref{sec:tld} (\p.\pageref{sec:tld}), and the \filename{README} +files for each. + +\item All \TeX-related input files are now collected in +the \dirname{tex} subdirectory of \dirname{texmf*} trees, rather than +having separate sibling directories \dirname{tex}, \dirname{etex}, +\dirname{pdftex}, \dirname{pdfetex}, etc. See +\CDref{texmf-dist/doc/generic/tds/tds.html\#Extensions} +{\texttt{texmf-dist/doc/generic/tds/tds.html\#Extensions}}. + +\item Helper scripts (not meant to be invoked by users) are now located +in a new \dirname{scripts} subdirectory of \dirname{texmf*} trees, and +can be searched for via \verb|kpsewhich -format=texmfscripts|. So if you have +programs which call such scripts, they'll need to be adjusted. See +\CDref{texmf-dist/doc/generic/tds/tds.html\#Scripts} +{\texttt{texmf-dist/doc/generic/tds/tds.html\#Scripts}}. + +\item Almost all formats leave most characters printable as +themselves via the ``translation file'' \filename{cp227.tcx}, instead of +translating them with the \verb|^^| notation. Specifically, characters +at positions 32--256, plus tab, vertical tab, and form feed are +considered printable and not translated. The exceptions are plain \TeX\ +(only 32--126 printable), \ConTeXt\ (0--255 printable), and the +\OMEGA-related formats. This default behavior is almost the same as in +\TL\,2003, but it's implemented more cleanly, with more possibilities +for customization. See \CDref{texmf-dist/doc/web2c/web2c.html\#TCX-files} +{\texttt{texmf-dist/doc/web2c/web2c.html\#TCX-files}}. +(By the way, with Unicode input, \TeX\ may output partial character +sequences when showing error contexts, since it is byte-oriented.) + +\item \textsf{pdfetex} is now the default engine for all formats +except (plain) \textsf{tex} itself. (Of course it generates DVI +when run as \textsf{latex}, etc.) This means, among other things, that +the microtypographic features of \textsf{pdftex} are available in +\LaTeX, \ConTeXt, etc., as well as the \eTeX\ features +(\OnCD{texmf-dist/doc/etex/base/}). + +It also means it's \emph{more important than ever} to use the +\pkgname{ifpdf} package (works with both plain and \LaTeX) or equivalent +code, because simply testing whether \cs{pdfoutput} or some other +primitive is defined is not a reliable way to determine if PDF +output is being generated. We made this backward compatible as best we +could this year, but next year, \cs{pdfoutput} may be defined even when +DVI is being written. + +\item pdf\TeX\ (\url{http://pdftex.org}) has many new features: + + \begin{itemize*} + + \item \cs{pdfmapfile} and \cs{pdfmapline} provide font map support + from within a document. + + \item Microtypographic font expansion can be used more easily.\\ + \url{http://www.ntg.nl/pipermail/ntg-pdftex/2004-May/000504.html} + + \item All parameters previously set through the special configuration + file \filename{pdftex.cfg} must now be set through primitives, + typically in \filename{pdftexconfig.tex}; \filename{pdftex.cfg} is no + longer supported. Any extant \filename{.fmt} files must be redumped + when \filename{pdftexconfig.tex} is changed. + + \item See the pdf\TeX\ manual for more: \OnCD{texmf-dist/doc/pdftex/manual/pdftex-a.pdf}. + + \end{itemize*} + +\item The \cs{input} primitive in \cmdname{tex} (and \cmdname{mf} and +\cmdname{mpost}) now accepts double quotes containing spaces and other +special characters. Typical examples: +\begin{verbatim} +\input "filename with spaces" % plain +\input{"filename with spaces"} % latex +\end{verbatim} +See the Web2C manual for more: \OnCD{texmf-dist/doc/web2c}. + +\item enc\TeX\ support is now included within Web2C and consequently all +\TeX\ programs, via the \optname{-enc} option\Dash \emph{only when +formats are built}. enc\TeX\ supports general re-encoding of input and +output, enabling full support of Unicode (in UTF-8). See +\OnCD{texmf-dist/doc/generic/enctex/} and +\url{http://www.olsak.net/enctex.html}. + +\item Aleph, a new engine combining \eTeX\ and \OMEGA, is available. +A little information is available in \OnCD{texmf-dist/doc/aleph/base} +and \url{http://www.tex.ac.uk/cgi-bin/texfaq2html?label=aleph}. The +\LaTeX-based format for Aleph is named \textsf{lamed}. + +\item The latest \LaTeX\ release has a new version of the +LPPL\Dash now officially a Debian-approved license. Assorted +other updates, see the \filename{ltnews} files in +\OnCD{texmf-dist/doc/latex/base}. + +\item \cmdname{dvipng}, a new program for converting DVI to +PNG image files, is included. See +\url{http://www.ctan.org/pkg/dvipng}. + +\item We reduced the \pkgname{cbgreek} package to a ``medium'' sized set +of fonts, with the assent and advice of the author (Claudio Beccari). +The excised fonts are the invisible, outline, and transparency ones, +which are relatively rarely used, and we needed the space. The full set +is of course available from CTAN +(\url{http://mirror.ctan.org/tex-archive/fonts/greek/cbfonts}). + +\item \cmdname{oxdvi} has been removed; just use \cmdname{xdvi}. + +\item The \cmdname{ini} and \cmdname{vir} commands (links) for +\cmdname{tex}, \cmdname{mf}, and \cmdname{mpost} are no longer created, +such as \cmdname{initex}. The \cmdname{ini} functionality has been +available through the command-line option \optname{-ini} for years now. + +\item \textsf{i386-openbsd} platform support was removed. Since the +\pkgname{tetex} package in the BSD Ports system is available, and +GNU/Linux and FreeBSD binaries were available, it seemed +volunteer time could be better spent elsewhere. + +\item On \textsf{sparc-solaris} (at least), you may have to set the +\envname{LD\_LIBRARY\_PATH} environment variable to run the +\pkgname{t1utils} programs. This is because they are compiled with C++, +and there is no standard location for the runtime libraries. (This is +not new in 2004, but wasn't previously documented.) Similarly, on +\textsf{mips-irix}, the MIPSpro 7.4 runtimes are required. + +\end{itemize} + +\subsubsection{2005} + +2005 saw the usual huge number of updates to packages and programs. +The infrastructure stayed relatively stable from 2004, but inevitably +there were some changes there as well: + +\begin{itemize} + +\item New scripts \cmdname{texconfig-sys}, \cmdname{updmap-sys}, and + \cmdname{fmtutil-sys} were introduced, which modify the + configuration in the system trees. The \cmdname{texconfig}, + \cmdname{updmap}, and \cmdname{fmtutil} scripts now modify + user-specific files, under \dirname{$HOME/.texlive2005}. + +\item Corresponding new variables \envname{TEXMFCONFIG} and + \envname{TEXMFSYSCONFIG} to specify the trees where configuration + files (user or system, respectively) are found. Thus, you may + need to move personal versions of \filename{fmtutil.cnf} and + \filename{updmap.cfg} to these places; another option is to + redefine \envname{TEXMFCONFIG} or \envname{TEXMFSYSCONFIG} in + \filename{texmf.cnf}. In any case the real location of these files + and the values of \envname{TEXMFCONFIG} and \envname{TEXMFSYSCONFIG} + must agree. + See section~\ref{sec:texmftrees}, \p.\pageref{sec:texmftrees}. + +\item Last year, we kept \verb|\pdfoutput| and other primitives undefined + for \dvi\ output, even though the \cmdname{pdfetex} program was + being used. This year, as promised, we undid that compatibility + measure. So if your document uses \verb|\ifx\pdfoutput\undefined| + to test if PDF is being output, it will need to be changed. You + can use the package \pkgname{ifpdf.sty} (which works under both + plain \TeX\ and \LaTeX) to do this, or steal its logic. + +\item Last year, we changed most formats to output (8-bit) characters as + themselves (see previous section). The new TCX file + \filename{empty.tcx} now provides an easier way to get the + original \verb|^^| notation if you so desire, as in: +\begin{verbatim} +latex --translate-file=empty.tcx yourfile.tex +\end{verbatim} + +\item The new program \cmdname{dvipdfmx} is included for translation of + DVI to PDF; this is an actively maintained update of + \cmdname{dvipdfm} (which is also still available for now, though + no longer recommended). + +\item The new programs \cmdname{pdfopen} and \cmdname{pdfclose} are included + to allow reloading of PDF files in the Adobe Acrobat Reader without + restarting the program. (Other PDF readers, notably \cmdname{xpdf}, + \cmdname{gv}, and \cmdname{gsview}, have never suffered from this + problem.) + +\item For consistency, the variables \envname{HOMETEXMF} and + \envname{VARTEXMF} have been renamed to \envname{TEXMFHOME} and + \envname{TEXMFSYSVAR}, respectively. There is also + \envname{TEXMFVAR}, which is by default user-specific. See the + first point above. + +\end{itemize} + + +\subsubsection{2006--2007} + +In 2006--2007, the major new addition to \TL{} was the \XeTeX{} program, +available as the \texttt{xetex} and \texttt{xelatex} programs; see +\url{http://scripts.sil.org/xetex}. + +MetaPost also received a notable update, with more planned for the +future (\url{http://tug.org/metapost/articles}), likewise pdf\TeX{} +(\url{http://tug.org/applications/pdftex}). + +The \TeX\ \filename{.fmt} (high-speed format) and the similar files for +MetaPost and \MF\ are now stored in subdirectories of \dirname{texmf/web2c}, +instead of in the directory itself (although the directory is still +searched, for the sake of existing \filename{.fmt}'s). The +subdirectories are named for the `engine' in use, such as \filename{tex} +or \filename{pdftex} or \filename{xetex}. This change should be +invisible in normal use. + +The (plain) \texttt{tex} program no longer reads \texttt{\%\&} first +lines to determine what format to run; it is the pure Knuthian \TeX. +(\LaTeX\ and everything else do still read \texttt{\%\&} lines). + +Of course the year also saw (the usual) hundreds of other updates to +packages and programs. As usual, please check CTAN +(\url{http://mirror.ctan.org}) for updates. + +Internally, the source tree is now stored in Subversion, with a standard +web interface for viewing the tree, as linked from our home page. +Although not visible in the final distribution, we expect this will +provide a stable development foundation for future years. + +Finally, in May 2006 Thomas Esser announced that he would no longer be +updating te\TeX{} (\url{http://tug.org/tetex}). As a result, there was +a surge of interest in \TL{}, especially among \GNU/Linux +distributors. (There is a new \texttt{tetex} installation scheme in +\TL{}, which provides an approximate equivalent.) We hope this will +eventually translate to improvements in the \TeX\ environment for +everyone. + +\subsubsection{2008} + +In 2008, the entire \TL{} infrastructure was redesigned and +reimplemented. Complete information about an installation is now stored +in a plain text file \filename{tlpkg/texlive.tlpdb}. + +Among other things, this finally makes possible upgrading a \TL{} +installation over the Internet after the initial installation, a feature +MiK\TeX\ has provided for many years. We expect to regularly update new +packages as they are released to \CTAN. + +The major new engine Lua\TeX\ (\url{http://luatex.org}) is included; +besides a new level of flexibility in typesetting, this provides an +excellent scripting language for use both inside and outside of \TeX\ +documents. + +Support among Windows and the Unix-based platforms is now much more +uniform. In particular, most Perl and Lua scripts are now available on +Windows, using the Perl internally distributed with \TL. + +The new \cmdname{tlmgr} script (section~\ref{sec:tlmgr}) is the +general interface for managing \TL{} after the initial installation. +It handles package updates and consequent regeneration of formats, map +files, and language files, optionally including local additions. + +With the advent of \cmdname{tlmgr}, the \cmdname{texconfig} actions to +edit the format and hyphenation configuration files are now disabled. + +The \cmdname{xindy} indexing program +(\url{http://xindy.sourceforge.net/}) is now included on most platforms. + +The \cmdname{kpsewhich} tool can now report all matches for a given file +(option \optname{--all}) and limit matches to a given subdirectory +(option \optname{--subdir}). + +The \cmdname{dvipdfmx} program now includes functionality to extract +bounding box information, via the command name \cmdname{extractbb}; this +was one of the last features provided by \cmdname{dvipdfm} not in +\cmdname{dvipdfmx}. + +The font aliases \filename{Times-Roman}, \filename{Helvetica}, and so on +have been removed. Different packages expected them to behave +differently (in particular, to have different encodings), and there was +no good way to resolve this. + +The \pkgname{platex} format has been removed, to resolve a name conflict +with a completely different Japanese \pkgname{platex}; the +\pkgname{polski} package is now the main Polish support. + +Internally, the \web\ string pool files are now compiled into the +binaries, to ease upgrades. + +Finally, the changes made by Donald Knuth in his `\TeX\ tuneup of 2008' +are included in this release. See +\url{http://tug.org/TUGboat/Articles/tb29-2/tb92knut.pdf}. + +\subsubsection{2009} + +In 2009, the default output format for Lua\AllTeX\ is now PDF, to take +advantage of Lua\TeX's OpenType support, et al. New executables named +\code{dviluatex} and \code{dvilualatex} run Lua\TeX\ with DVI output. +The Lua\TeX\ home page is \url{http://luatex.org}. + +The original Omega engine and Lambda format have been excised, after +discussions with the Omega authors. The updated Aleph and Lamed remain, +as do the Omega utilities. + +A new release of the AMS \TypeI\ fonts is included, including Computer +Modern: a few shape changes made over the years by Knuth in the Metafont +sources have been integrated, and the hinting has been updated. The +Euler fonts have been thoroughly reshaped by Hermann Zapf (see +\url{http://tug.org/TUGboat/Articles/tb29-2/tb92hagen-euler.pdf}). In +all cases, the metrics remain unchanged. The AMS fonts home page is +\url{http://www.ams.org/tex/amsfonts.html}. + +The new \GUI{} front end \TeX{}works is included for Windows, and also in +Mac\TeX. For other platforms, and more information, see the \TeX{}works +home page, \url{http://tug.org/texworks}. It is a cross-platform front +end inspired by the \MacOSX\ TeXShop editor, aiming at ease-of-use. + +The graphics program Asymptote is included for several platforms. This +implements a text-based graphics description language vaguely akin to +MetaPost, but with advanced 3D support and other features. Its home +page is \url{http://asymptote.sourceforge.net}. + +The separate \code{dvipdfm} program has been replaced by +\code{dvipdfmx}, which operates in a special compatibility mode under +that name. \code{dvipdfmx} includes CJK support and has +accumulated many other fixes over the years since the last +\code{dvipdfm} release. + +Executables for the \pkgname{cygwin} and \pkgname{i386-netbsd} platforms +are now included, while we were advised that OpenBSD users get +\TeX\ through their package systems, plus there were difficulties in +making binaries that have a chance of working on more than one version. + +A miscellany of smaller changes: we now use \pkgname{xz} compression, +the stable replacement for \pkgname{lzma} +(\url{http://tukaani.org/xz/}); a literal |$| is allowed in filenames +when it does not introduce a known variable name; the Kpathsea library +is now multi-threaded (made use of in MetaPost); the entire \TL{} build +is now based on Automake. + +Final note on the past: all releases of \TL{}, along with ancillary +material such as \CD\ labels, are available at +\url{ftp://tug.org/historic/systems/texlive}. + + +\subsubsection{2010} +\label{sec:2010news} % keep with 2010 + +In 2010, the default version for PDF output is now 1.5, enabling more +compression. This applies to all the \TeX\ engines when used to produce +PDF and to \code{dvipdfmx}. Loading the \pkgname{pdf14} \LaTeX\ package +changes back to PDF~1.4, or set |\pdfminorversion=4|. + +pdf\AllTeX\ now \emph{automatically} converts a requested Encapsulated +PostScript (EPS) file to PDF, via the \pkgname{epstopdf} package, when +and if the \LaTeX\ \code{graphics.cfg} configuration file is loaded, and +PDF is being output. The default options are intended to eliminate any +chance of hand-created PDF files being overwritten, but you can also +prevent \code{epstopdf} from being loaded at all by putting +|\newcommand{\DoNotLoadEpstopdf}{}| (or |\def...|) before the +\cs{documentclass} declaration. It is also not loaded if the +\pkgname{pst-pdf} package is used. For more details, see the +\pkgname{epstopdf} package documentation +(\url{http://ctan.org/pkg/epstopdf-pkg}). + +A related change is that execution of a very few external commands from +\TeX, via the \cs{write18} feature, is now enabled by default. These +commands are \code{repstopdf}, \code{makeindex}, \code{kpsewhich}, +\code{bibtex}, and \code{bibtex8}; the list is defined in +\code{texmf.cnf}. Environments which must disallow all such external +commands can deselect this option in the installer (see +section~\ref{sec:options}), or override the value after installation by +running |tlmgr conf texmf shell_escape 0|. + +Yet another related change is that \BibTeX\ and Makeindex now refuse to +write their output files to an arbitrary directory (like \TeX\ itself), +by default. This is so they can now be enabled for use by the +restricted \cs{write18}. To change this, the \envname{TEXMFOUTPUT} +environment variable can be set, or the |openout_any| setting changed. + +\XeTeX\ now supports margin kerning along the same lines as pdf\TeX. +(Font expansion is not presently supported.) + +By default, \prog{tlmgr} now saves one backup of each package updated +(\code{tlmgr option autobackup 1}), so broken package updates can be +easily reverted with \code{tlmgr restore}. If you do post-install +updates, and don't have the disk space for the backups, run \code{tlmgr +option autobackup 0}. + +New programs included: the p\TeX\ engine and related utilities for +typesetting Japanese; the \BibTeX{}U program for Unicode-enabled +\BibTeX; the \prog{chktex} utility +(\url{http://baruch.ev-en.org/proj/chktex}) for checking \AllTeX\ +documents; the \prog{dvisvgm} (\url{http://dvisvgm.sourceforge.net}) +DVI-to-SVG translator. + +Executables for these new platforms are now included: \code{amd64-freebsd}, +\code{amd64-kfreebsd}, \code{i386-freebsd}, \code{i386-kfreebsd}, +\code{x86\_64-darwin}, \code{x86\_64-solaris}. + +A change in \TL{} 2009 that we failed to note: numerous \TeX4ht-related +executables (\url{http://tug.org/tex4ht}) were removed from the binary +directories. The generic \code{mk4ht} program can be used to run any of +the various \code{tex4ht} combinations. + +Finally, the \TL{} release on the \TK\ \DVD\ can no longer be run live +(oddly enough). A single \DVD\ no longer has enough room. One +beneficial side effect is that installation from the physical \DVD\ is +much faster. + +\subsubsection{2011} + +The \MacOSX\ binaries (\code{universal-darwin} and +\code{x86\_64-darwin}) now work only on Leopard or later; Panther and +Tiger are no longer supported. + +The \code{biber} program for bibliography processing is included on +common platforms. Its development is closely coupled with the +\code{biblatex} package, which completely reimplements the +bibliographical facilities provided by LaTeX. + +The MetaPost (\code{mpost}) program no longer creates or uses +\code{.mem} files. The needed files, such as \code{plain.mp}, are +simply read on every run. This is related to supporting MetaPost as a +library, which is another significant though not user-visible change. + +The \code{updmap} implementation in Perl, previously used only on +Windows, has been revamped and is now used on all platforms. There +shouldn't be any user-visible changes as a result, except that it runs +much faster. + +The \cmdname{initex} and \cmdname{inimf} programs were restored (but no +other \cmdname{ini*} variants). + +\subsubsection{2012} + +\code{tlmgr} supports updates from multiple network repositories. The +section on multiple repositories in the \code{tlmgr help} output has +more. + +The parameter \cs{XeTeXdashbreakstate} is set to~1 by default, for both +\code{xetex} and \code{xelatex}. This allows line breaks after +em-dashes and en-dashes, which has always been the behavior of plain +\TeX, \LaTeX, Lua\TeX, etc. Existing \XeTeX\ documents which must +retain perfect line-break compatibility will need to set +\cs{XeTeXdashbreakstate} to~0 explicitly. + +The output files generated by \code{pdftex} and \code{dvips}, among +others, can now exceed 2 gigabytes. + +The 35 standard PostScript fonts are included in the output of +\code{dvips} by default, since so many different versions of them are +extant. + +In the restricted \cs{write18} execution mode, set by default, +\code{mpost} is now an allowed program. + +A \code{texmf.cnf} file is also found in \filename{../texmf-local}, +e.g., \filename{/usr/local/texlive/texmf-local/web2c/texmf.cnf}, if it +exists. + +The \code{updmap} script reads a per-tree \code{updmap.cfg} instead of +one global config. This change should be invisible, unless you edited +your updmap.cfg's directly. The \verb|updmap --help| output has more. + +Platforms: \pkgname{armel-linux} and \pkgname{mipsel-linux} added; +\pkgname{sparc-linux} and \pkgname{i386-netbsd} are no longer in the +main distribution. + +\subsubsection{2013} + +Distribution layout: the top-level \code{texmf/} directory has been +merged into \code{texmf-dist/}, for simplicity. Both the +\code{TEXMFMAIN} and \code{TEXMFDIST} Kpathsea variables now point to +\code{texmf-dist}. + +Many small language collections have been merged together, to simplify +installation. + +\MP: native support for PNG output and floating-point (IEEE double) has +been added. + +Lua\TeX: updated to Lua 5.2, and includes a new library +(\code{pdfscanner}) to process external PDF page content, among much +else (see its web pages). + +\XeTeX\ (also see its web pages for more): +\begin{itemize*} +\item The HarfBuzz library is now used for font layout instead of +ICU. (ICU is still used to support input encodings, bidirectionality, +and the optional Unicode line breaking.) +\item Graphite2 and HarfBuzz are used instead of SilGraphite for Graphite +layout. +\item On Macs, Core Text is used instead of the (deprecated) ATSUI. +\item Prefer TrueType/OpenType fonts to Type1 when the names are the same. +\item Fix occasional mismatch in font finding between \XeTeX\ and +\code{xdvipdfmx}. +\item Support OpenType math cut-ins. +\end{itemize*} + +\cmdname{xdvi}: now uses FreeType instead of \code{t1lib} for rendering. + +\pkgname{microtype.sty}: some support for \XeTeX\ (protrusion) and +Lua\TeX\ (protrusion, font expansion, tracking), among other +enhancements. + +\cmdname{tlmgr}: new \code{pinning} action to ease configuring multiple +repositories; that section in \verb|tlmgr --help| has more, online at +\url{http://tug.org/texlive/doc/tlmgr.html#MULTIPLE-REPOSITORIES}. + +Platforms: \pkgname{armhf-linux}, \pkgname{mips-irix}, +\pkgname{i386-netbsd}, and \pkgname{amd64-netbsd} added or revived; +\pkgname{powerpc-aix} removed. + +\subsubsection{2014} + +2014 saw another \TeX\ tune-up from Knuth; this affected all engines, +but the only visible change likely is the restoration of the +\code{preloaded format} string on the banner line. Per Knuth, this now +reflects the format that \emph{would} be loaded by default, rather than +an undumped format that is actually preloaded in the binary; it may be +overridden in various ways. + +pdf\TeX: new warning-suppression parameter +\cs{pdfsuppresswarningpagegroup}; new primitives for fake interword +spaces to help with PDF text reflowing: \cs{pdfinterwordspaceon}, +\cs{pdfinterwordspaceoff}, \cs{pdffakespace}. + +Lua\TeX: Notable changes and fixes were made to font loading and +hyphenation. The biggest addition is a new engine variant, +\code{luajittex} (\url{http://foundry.supelec.fr/projects/luajittex}) +and its siblings \code{texluajit} and \code{texluajitc}. This uses a +just-in-time Lua compiler (detailed \textsl{TUGboat} article at +\url{http://tug.org/TUGboat/tb34-1/tb106scarso.pdf}). \code{luajittex} +is still in development, is not available on all platforms, and is +considerably less stable than \code{luatex}. Neither we nor its +developers recommend using it except for the specific purpose of +experimenting with jit on Lua code. + +\XeTeX: The same image formats are now supported on all platforms +(including Mac); avoid Unicode compatibility decomposition fallback (but +not other variants); prefer OpenType to Graphite fonts, for +compatibility with previous \XeTeX\ versions. + +\MP: A new numbersystem \code{decimal} is supported, along with a +companion internal \code{numberprecision}; a new definition of +\code{drawdot} in \filename{plain.mp}, per Knuth; bug fixes in +SVG and PNG output, among others. + +The \cmdname{pstopdf} Con\TeX{}t utility will be removed as a standalone +command at some point after the release, due to conflicts with OS +utilities of the same name. It can still (and now) be invoked as +\code{mtxrun --script pstopdf}. + +\cmdname{psutils} has been substantially revised by a new maintainer. +As a result, several seldom-used utilities (\code{fix*}, \code{getafm}, +\code{psmerge}, \code{showchar}) are now only in the \dirname{scripts/} +directory rather than being user-level executables (this can be reversed +if it turns out to be problematic). A new script, \code{psjoin}, has +been added. + +The Mac\TeX\ redistribution of \TeX\ Live (section~\ref{sec:macosx}) no +longer includes the optional Mac-only packages for the Latin Modern and +\TeX\ Gyre fonts, since it is easy enough for individual users to make +them available to the system. The \cmdname{convert} program from +ImageMagick has also been excised, since \TeX4ht (specifically +\code{tex4ht.env}) now uses Ghostscript directly. + +The \pkgname{langcjk} collection for Chinese, Japanese, and Korean +support has been split into individual language collections for the sake +of more moderate sizes. + +Platforms: \pkgname{x86\_64-cygwin} added, \pkgname{mips-irix} removed; +Microsoft no longer supports Windows XP, so our programs may +start failing there at any time. + +\subsubsection{2015} + +\LaTeXe\ now incorporates, by default, changes previously included only +by explicitly loading the \pkgname{fixltx2e} package, which is now a +no-op. A new \pkgname{latexrelease} package and other mechanisms allow +for controlling what is done. The included \LaTeX\ News \#22 and +``\LaTeX\ changes'' documents have details. Incidentally, the +\pkgname{babel} and \pkgname{psnfss} packages, while core parts of +\LaTeX, are maintained separately and are not affected by these changes +(and should still work). + +Internally, \LaTeXe\ now includes Unicode-related engine configuration +(what characters are letters, naming of primitives, etc.) which was +previously part of \TeX\ Live. This change is intended to be invisible +to users; a few low-level internal control sequences have been renamed +or removed, but the behavior should be just the same. + +pdf\TeX: Support JPEG Exif as well as JFIF; do not +emit a warning if \cs{pdfinclusionerrorlevel} is negative; sync +with \prog{xpdf}~3.04. + +Lua\TeX: New library \pkgname{newtokenlib} for scanning tokens; bug +fixes in the \code{normal} random number generator and other places. + +\XeTeX: Image handling fixes; \prog{xdvipdfmx} binary looked for first +as a sibling to \prog{xetex}; internal \code{XDV} opcodes changed. + +MetaPost: New numbersystem \code{binary}; new Japanese-enabled +\prog{upmpost} and \prog{updvitomp} programs, analogous to +\prog{up*tex}. + +Mac\TeX: Updates to the included Ghostscript package for CJK +support. The \TeX\ Distribution Preference Pane now works in Yosemite +(\MacOSX~10.10). Resource-fork font suitcases (generally without an +extension) are no longer supported by \XeTeX; data-fork suitcases +(\code{.dfont}) remain supported. + +Infrastructure: The \prog{fmtutil} script has been reimplemented to read +\filename{fmtutil.cnf} on a per-tree basis, analogous to \prog{updmap}. +Web2C \prog{mktex*} scripts (including \prog{mktexlsr}, \prog{mktextfm}, +\prog{mktexpk}) now prefer programs in their own directory, instead of +always using the existing \envname{PATH}. + +Platforms: \pkgname{*-kfreebsd} removed, since \TeX\ Live is now easily +available through the system platform mechanisms. +Support for some additional platforms is available as custom binaries +(\url{http://tug.org/texlive/custom-bin.html}). In addition, some +platforms are now omitted from the \DVD\ (simply to save space), but can +be installed normally over the net. + +% +\subsubsection{2016} + +Lua\TeX: Sweeping changes to primitives, both renames and removals, +along with some node structure rearrangements. The changes are +summarized in an article by Hans Hagen, ``Lua\TeX\ 0.90 backend changes +for PDF and more'' +(\url{http://tug.org/TUGboat/tb37-1/tb115hagen-pdf.pdf}); for all the +details, see the Lua\TeX\ manual, +\OnCD{texmf-dist/doc/luatex/base/luatex.pdf}. + +Metafont: New highly experimental sibling programs MFlua and MFluajit, +integrating Lua with \MF, for trial testing purposes. + +MetaPost: Bug fixes and internal preparations for MetaPost 2.0. + +\code{SOURCE\_DATE\_EPOCH} support in all engines except Lua\TeX\ (which +will come in the next release) and original \code{tex} (intentionally +omitted): if the environment variable \code{SOURCE\_DATE\_EPOCH} is set, +its value is used for timestamps in the PDF output. If +\code{SOURCE\_DATE\_EPOCH\_TEX\_PRIMITIVES} is also set, the +\code{SOURCE\_DATE\_EPOCH} value is used to initialize the \TeX\ +primitives \cs{year}, \cs{month}, \cs{day}, \cs{time}. The pdf\TeX\ +manual has examples and details. + +pdf\TeX: new primitives \cs{pdfinfoomitdate}, \cs{pdftrailerid}, +\cs{pdfsuppressptexinfo}, to control values appearing in the output +which normally change with each run. These features are for PDF output +only, not DVI. + +Xe\TeX: New primitives \cs{XeTeXhyphenatablelength}, +\cs{XeTeXgenerateactualtext},\\ \cs{XeTeXinterwordspaceshaping}, +\cs{mdfivesum}; character class limit increased to 4096; DVI id byte +incremented. + +Other utilities: +\begin{itemize*} +\item \code{gregorio} is a new program, part of the \code{gregoriotex} +package for typesetting Gregorian chant scores; it is included in +\code{shell\_escape\_commands} by default. + +\item \code{upmendex} is an index creation program, mostly compatible +with \code{makeindex}, with support for Unicode sorting, among other +changes. + +\item \code{afm2tfm} now makes only accent-based height adjustments +upward; a new option \code{-a} omits all adjustments. + +\item \code{ps2pk} can handle extended PK/GF fonts. +\end{itemize*} + +Mac\TeX: The \TeX\ Distribution Preference Pane is gone; its +functionality is now in TeX Live Utility; bundled GUI applications +upgraded; new script \code{cjk-gs-integrate} to be run by users who wish +to incorporate various CJK fonts into Ghostscript. + +Infrastructure: System-level \code{tlmgr} configuration file supported; +verify package checksums; if GPG is available, verify signature of +network updates. These checks happen with both the installer and +\code{tlmgr}. (If GPG is not available, updates proceed as usual.) + +Platforms: \code{alpha-linux} and \code{mipsel-linux} removed. + +% +\subsubsection{2017} + +Lua\TeX: More callbacks, more typesetting control, more access to +internals; \code{ffi} library for dynamic code loading added on some +platforms. + +pdf\TeX: Environment variable |SOURCE_DATE_EPOCH_TEX_PRIMITIVES| from +last year renamed to |FORCE_SOURCE_DATE|, with no changes in +functionality; if the \cs{pdfpageattr} token list contains the string +\code{/MediaBox}, omit output of the default \code{/MediaBox}. + +Xe\TeX: Unicode/OpenType math now based on HarfBuzz's MATH table support; +some bug fixes. + +Dvips: Make the last papersize special win, for consistency with +\code{dvipdfmx} and package expectations; the \code{-L0} option (\code{L0} +config setting) restores the previous behavior of the first special +winning. + +ep\TeX, eup\TeX: New primitives \cs{pdfuniformdeviate}, +\cs{pdfnormaldeviate}, \cs{pdfrandomseed}, \cs{pdfsetrandomseed}, +\cs{pdfelapsedtime}, \cs{pdfresettimer}, from pdf\TeX. + +Mac\TeX: As of this year, only \MacOSX\ releases for which Apple still +releases security patches will be supported in Mac\TeX, under the +platform name |x86_64-darwin|; currently this means Yosemite, +El~Capitan, and Sierra (10.10 and newer). Binaries for older \MacOSX\ +versions are not included in Mac\TeX, but are still available in \TeX\ +Live (|x86_64-darwinlegacy|, \code{i386-darwin}, \code{powerpc-darwin}). + +Infrastructure: The \envname{TEXMFLOCAL} tree is now searched before +\envname{TEXMFSYSCONFIG} and \envname{TEXMFSYSVAR} (by default); the +hope is that this will better match expectations of local files +overriding system files. Also, \code{tlmgr} has a new mode \code{shell} +for interactive and scripted use, and a new action \code{conf auxtrees} +to easily add and remove extra trees. + +\code{updmap} and \code{fmtutil}: These scripts now give a warning when +invoked without explicitly specifying either so-called system mode +(\code{updmap-sys}, \code{fmtutil-sys}, or option \code{-sys}), or user +mode (\code{updmap-user}, \code{fmtutil-user}, or option \code{-user}). +The hope is that this will reduce the perennial problem of invoking user +mode by accident and thus losing future system updates. See +\url{http://tug.org/texlive/scripts-sys-user.html} for details. + +\code{install-tl}: Personal paths such as \envname{TEXMFHOME} are now +set to Mac\TeX\ values (|~/Library/...|)\ by default on Macs. New +option \code{-init-from-profile} to start an installation with the +values from a given profile; new command \code{P} to explicitly save a +profile; new profile variable names (but previous ones are still +accepted). + +Sync\TeX: the name of the temporary file now looks like +\code{foo.synctex(busy)}, instead of \code{foo.synctex.gz(busy)} +(no~\code{.gz}). Front ends and build systems that want to remove temp +files may need adjusting. + +Other utilities: \code{texosquery-jre8} is a new cross-platform program +for retrieving locale and other OS information from a \TeX\ document; it +is included in |shell_escape_commands| by default for restricted +shell execution. (Older JRE versions are supported by texosquery, but +cannot be enabled in restricted mode, as they are no longer supported by +Oracle, even for security issues.) + +Platforms: See Mac\TeX\ entry above; no other changes. + +% +\subsubsection{2018} + +Kpathsea: Case-insensitive filename matching now done by default in +non-system directories; set \code{texmf.cnf} or environment variable +\code{texmf\_casefold\_search} to~\code{0} to disable. +Full details in the Kpathsea manual (\url{http://tug.org/kpathsea}). + +ep\TeX, eup\TeX: New primitive \cs{epTeXversion}. + +Lua\TeX: Preparation for moving to Lua 5.3 in 2019: a binary +\code{luatex53} is available on most platforms, but must be renamed to +\code{luatex} to be effective. Or use the \ConTeXt\ Garden +(\url{http://wiki.contextgarden.net}) files; more information there. + +MetaPost: Fixes for wrong path directions, TFM and PNG output. + +pdf\TeX: Allow encoding vectors for bitmap fonts; current directory not +hashed into PDF ID; bug fixes for \cs{pdfprimitive} and related. + +Xe\TeX: Support \code{/Rotate} in PDF image inclusion; exit nonzero if +the output driver fails; various obscure UTF-8 and other primitive +fixes. + +Mac\TeX: See version support changes below. In addition, the files +installed in \code{/Applications/TeX/} by Mac\TeX\ have been reorganized for +greater clarity; now this location contains four GUI programs (BibDesk, +LaTeXiT, TeX Live Utility, and TeXShop) at the top level and folders +with additional utilities and documentation. + +\code{tlmgr}: new front-ends \code{tlshell} (Tcl/Tk) and +\code{tlcockpit} (Java); JSON output; \code{uninstall} now a synonym +for \code{remove}; new action/option \code{print-platform-info}. + +Platforms: +\begin{itemize*} +\item +Removed: \code{armel-linux}, \code{powerpc-linux}. + +\item \code{x86\_64-darwin} supports 10.10--10.13 +(Yosemite, El~Capitan, Sierra, and High~Sierra). + +\item \code{x86\_64-darwinlegacy} supports 10.6--10.10 (though +\code{x86\_64-darwin} is preferred for 10.10). All support for 10.5 +(Leopard) is gone, that is, both the \code{powerpc-darwin} and +\code{i386-darwin platforms} have been removed. + +\item Windows: XP is no longer supported. +\end{itemize*} + + +\htmlanchor{news} +\subsection{Present: 2019} +\label{sec:tlcurrent} + +Kpathsea: More consistent brace expansion and path splitting; new +variable \code{TEXMFDOTDIR} instead of hard-coded \code{.}\ in paths +allows for easily searching additional or sub-directories (see comments +in \code{texmf.cnf}). + +ep\TeX, eup\TeX: New primitives \cs{readpapersizespecial} and +\cs{expanded}. + +Lua\TeX: Lua 5.3 now used, with concomitant arithmetic and interface changes. +The homegrown library pplib is used to read pdf files, thus +eliminating the dependency on poppler (and the need for C++); +Lua interface changed accordingly. + +MetaPost: \code{r-mpost} command name recognized as an +alias for invocation with the \code{--restricted} option, and added to +the list of restricted commands available by default. +Minimum precision now 2 for decimal and binary mode. +Binary mode no longer available in MPlib but still available in +standalone MetaPost. + +pdf\TeX: New primitive \cs{expanded}; if new primitive parameter +\cs{pdfomitcharset} is set to 1, the \code{/CharSet} string +omitted from the PDF output, since it cannot feasibly be guaranteed +correct, as required by PDF/A-2 and PDF/A-3. + +Xe\TeX: New primitives \cs{expanded}, +\cs{creationdate}, +\cs{elapsedtime}, +\cs{filedump}, +\cs{filemoddate}, +\cs{filesize}, +\cs{resettimer}, +\cs{normaldeviate}, +\cs{uniformdeviate}, +\cs{randomseed}; extend \cs{Ucharcat} to produce active +characters. + +\code{tlmgr}: Support \code{curl} as a download program; + use \code{lz4} and gzip before \code{xz} for local backups, if available; + prefer system-provided binaries over binaries provided with \TL\ for + compressor and download programs, unless the environment variable + \code{TEXLIVE\_PREFER\_OWN} is set. + +\code{install-tl}: New option \code{-gui} (with no argument) is the +default on Windows and Macs, and invokes a new Tcl/TK GUI (see +sections~\ref{sec:basic} and~\ref{sec:graphical-inst}). + +Utilities: +\begin{itemize*} +\item \code{cwebbin} (\url{https://ctan.org/pkg/cwebbin}) is now the CWEB +implementation in \TeX\ Live, with support for more language dialects, +and including the \code{ctwill} program to make mini-indexes. + +\item \code{chkdvifont}: report font information from \dvi{} files, also +from tfm/ofm, vf, gf, pk. + +\item \code{dvispc}: make a DVI file page-independent with respect to specials. +\end{itemize*} + +Mac\TeX: \code{x86\_64-darwin} now supports 10.12 and higher (Sierra, +High Sierra, Mojave); \code{x86\_64-darwinlegacy} still supports 10.6 +and newer. The spell checker Excalibur is no longer included, since it +requires 32-bit support. + +Platforms: removed \code{sparc-solaris}. + + +\subsection{Future} + +\TL{} is not perfect, and never will be. We intend to continue to +release new versions, and would like to provide more documentation, more +programs, an ever-improved and better-checked tree of macros and fonts, +and anything else \TeX.

In 1990, Karl Berry took over the work, assisted by dozens of additional contributors, and in 1997 he handed the baton to Olaf Weber, who returned it to Karl in 2006. -

    In order to adapt optimally to all operating systems’ conventions, on non-Unix systems Kpathsea can use filename separators different from colon (‘:’) and slash (‘/’). -

    To check a particular path element

    To check a particular path element p, Kpathsea first checks if a prebuilt database (see “Filename database” on page 66) applies to p, i.e., if the database is in a directory that is a prefix of p. If so, the path specification is matched against the contents of the database. -

    Although the simplest and most common path element is a directory name, Kpathsea supports additional features in search paths: layered default values, environment variable names, config file values, users’ home directories, and recursive subdirectory searching. Thus, we say that Kpathsea expands a path element, meaning it transforms all the specifications into basic directory name or names. This is described in the following sections in the same order as it takes place. -

    Note that if the filename being searched for is absolute or explicitly relative, i.e., starts with ‘

Nevertheless, at installations with -enough directories, searching each possible directory for a given file can take an excessively long time (this is -especially true if many hundreds of font directories have to be traversed.) Therefore, Kpathsea can use an -externally-built plain text “database” file named ls-R that maps files to directories, thus avoiding the need to -exhaustively search the disk. -

    (In the distributed file, the second path element is also slightly more complicated than $TEXMF/tex//. But +that’s minor; here we want to discuss the $TEXMFDOTDIR feature.) +

    The reason to use the variable $TEXMFDOTDIR in the path definitions instead of simply ‘.’ is purely so that +it can be overridden. For example, a complex document may have many source files arranged in many +subdirectories. To handle that, you can set TEXMFDOTDIR to .// (for example, in the environment when you +build the document) and they will all get searched. (Warning: don’t use .// by default; it’s usually +highly undesirable, and potentially insecure, to search through all subdirectories for an arbitrary +document.) +

    SOURCE_DATE_EPOCH support in all engines except LuaTEX (which will come in the next release) and original \day, \time. The pdfTEX manual has examples and details. -

    pdfT

    pdfTEX: new primitives \pdfinfoomitdate, \pdftrailerid, \pdfsuppressptexinfo, to control values appearing in the output which normally change with each run. These features are for PDF output only, not DVI. -

    XeT

    MacT

    MacTEX: The TEX Distribution Preference Pane is gone; its functionality is now in TeX Live Utility; bundled GUI applications upgraded; new script cjk-gs-integrate to be run by users who wish to incorporate various CJK fonts into Ghostscript. -

    Infrastructure: System-level

    Infrastructure: System-level tlmgr configuration file supported; verify package checksums; if GPG is available, verify signature of network updates. These checks happen with both the installer and tlmgr. (If -GPG is not available, updates proceed as usual.) -

    Platforms: tlmgr. If GPG +is not available, updates proceed as usual. +

    Platforms: alpha-linux and mipsel-linux removed. -

    LuaTEX: More callbacks, more typesetting control, more access to internals; ffi library for dynamic code loading added on some platforms. -

    pdfT

    pdfTEX: Environment variable SOURCE_DATE_EPOCH_TEX_PRIMITIVES from last year renamed to \pdfpageattr token list contains the string /MediaBox, omit output of the default /MediaBox. -

    XeT

    epT

    epTEX, eupTEX: New primitives \pdfuniformdeviate, \pdfsetrandomseed, \pdfelapsedtime, \pdfresettimer, from pdfTEX. -

    MacT

    MacTEX: As of this year, only Mac OS X releases for which Apple still releases security patches will be supported in MacTEX, under the platform name i386-darwin, class="ec-lmtt-10">powerpc-darwin). -

    updmap and fmtutil: These scripts now give a warning when invoked without explicitly specifying either so-called system mode (fmtutil-user, or option -user). The hope is that this will reduce the perennial problem of invoking user mode by accident and thus losing future system updates. See http://tug.org/texlive/scripts-sys-user.html for +href="https://tug.org/texlive/scripts-sys-user.html" class="url" >https://tug.org/texlive/scripts-sys-user.html for details. -

    install-tl: Personal paths such as TEXMFHOME are now set to MacTEX values (-init-from-profile to start an installation with the v new command P to explicitly save a profile; new profile variable names (but previous ones are still accepted). -

    SyncT

    SyncTEX: the name of the temporary file now looks like foo.synctex(busy), instead of foo.synctex.gz(busy) (no .gz). Front ends and build systems that want to remove temp files may need +class="ec-lmtt-10">.gz). Front-ends and build systems that want to remove temp files may need adjusting. -

    Other utilities:

    Other utilities: texosquery-jre8 is a new cross-platform program for retrieving locale and other OS information from a TEX document; it is included in shell_escape_commands by default for restricted shell execution. (Older JRE versions are supported by texosquery, but cannot be enabled in restricted mode, as they are no longer supported by Oracle, even for security issues.) -

    Kpathsea: More consistent brace expansion and path splitting; new variable TEXMFDOTDIR instead of hard-coded . in paths allows for easily searching additional or sub-directories (see comments in texmf.cnf). -

    epT

    epTEX, eupTEX: New primitives \readpapersizespecial and \expanded. -

    LuaT

    LuaTEX: Lua 5.3 now used, with concomitant arithmetic and interface changes. The homegrown library pplib is used to read pdf files, thus eliminating the dependency on poppler (and the need for C++); Lua interface changed accordingly. -

    MetaPost:

    MetaPost: r-mpost command name recognized as an alias for invocation with the –restricted option, and added to the list of restricted commands available by default. Minimum precision now 2 for decimal and binary mode. Binary mode no longer available in MPlib but still available in standalone MetaPost. -

    pdfT

    pdfTEX: New primitive \expanded; if new primitive parameter \pdfomitcharset is set to 1, the /CharSet string omitted from the PDF output, since it cannot feasibly be guaranteed correct, as required by PDF/A-2 and PDF/A-3. -

    XeT

    XeTEX: New primitives \expanded, \creationdate, \uniformdeviate, \randomseed; extend \Ucharcat to produce active characters. -

    tlmgr: Support curl as a download program; use lz4 and gzip before T< class="E">EX Live for compressor and download programs, unless the environment variable TEXLIVE_PREFER_OWN is set. -

    install-tl: New option -gui (with no argument) is the default on Windows and Macs, and invokes a new Tcl/TK GUI (see sections 1.3 and 3.1.6). -

    9.2 Present: 2020

    +

    General: +

      +
    • The \input primitive in all TEX engines, including tex, now also accepts a group-delimited + filename argument, as a system-dependent extension. The usage with a standard + space/token-delimited filename is completely unchanged. The group-delimited argument was + previously implemented in LuaTEX; now it is available in all engines. ASCII double quote + characters (") are removed from the filename, but it is otherwise left unchanged after tokenization. + This does not currently affect LATEX’s \input command, as that is a macro redefinition of the + standard \input primitive. +
    • +
    • New option –cnf-line for kpsewhich, tex, mf, and all other engines, to support arbitrary + configuration settings on the command line. +
    • +
    • The addition of various primitives to various engines in this and previous years is intended + to result in a common set of functionality available across all engines (LATEX News #31, + https://latex-project.org/news). +
    + + +

    epTEX, eupTEX: New primitives \Uchar, \Ucharcat, \current(x)spacingmode, \ifincsname; revise +\fontchar?? and \iffontchar. For eupTEXonly: \currentcjktoken. +

    LuaTEX: Integration with HarfBuzz library, available as new engines luahbtex (used for lualatex) and +luajithbtex. New primitives: \eTeXgluestretch, \eTeXglueshrink, \eTeXglueorder. +

    pdfTEX: New primitive \pdfmajorversion; this merely changes the version number in the PDF output, +has no effect on PDF content. \pdfximage and similar now search for image files in the same way as +\openin. +

    pTEX: New primitives \ifjfont, \iftfont. Also in epTEX, upTEX, eupTEX. +

    XeTEX: New \filedump primitive, and fixes for \Umathchardef, \XeTeXinterchartoks, +\pdfsavepos. +

    Dvips: Output encodings for bitmap fonts, for better copy/paste capabilities +(https://tug.org/TUGboat/tb40-2/tb125rokicki-type3search.pdf). +

    MacTEX: MacTEX and x86_64-darwin now require 10.13 or higher (High Sierra, Mojave, and Catalina); +x86_64-darwinlegacy supports 10.6 and newer. MacTEX is notarized and command line programs have +hardened runtimes, as now required by Apple for install packages. BibDesk and TEX Live Utility are +not in MacTEX because they are not notarized, but a README file lists urls where they can be +obtained. +

    tlmgr and infrastructure: +

      +
    • Automatically retry (once) packages that fail to download. +
    • +
    • New option tlmgr check texmfdbs, to to check consistency of ls-R files and !! specifications + for each tree. +
    • +
    • Use versioned filenames for the package containers, as in tlnet/archive/pkgname.rNNN.tar.xz; + should be invisible to users, but a notable change in distribution. +
    • +
    • catalogue-date information no longer propagated from the TEX Catalogue, since it was often + unrelated to package updates.
    +

    9.3 Future

    TFuture +

    TEX Live is not perfect, and never will be. We intend to continue to release new versions, and would like to provide more documentation, more programs, an ever-improved and better-checked tree of macros and fonts, and anything else TEX. This work is all done by volunteers in their spare time, and so there is always more to do. Please see http://tug.org/texlive/contribute.html. -
