See the \href{https://www.gnu.org/licenses/gpl-3.0.html}{GNU General Public License} +for more details. + +\section{Motivation and Acknowledgments} + +The original idea was to extend the functionality of the \scriptname{pst2pdf}\cite{pst2pdf} +script to work with \env{tikzpicture} and other environments. The \pkgname{tikz}\cite{tikz} package +allows to \emph{externalize} the environments, but, the idea was to be able to extend this +to \emph{any type} of environment covering three central points: + +\begin{enumerate}[font=\small,noitemsep,leftmargin=*,nosep] + +\item Generate a separate image files for environments. + +\item Generate a standalone files with only the extracted environments. + +\item Generate a file replacing the environments by \ics{includegraphics}. +\end{enumerate} + +\thispagestyle{plain} + +\newpage + +\pagestyle{myheader} + +From the side of \hologo{TeX} there are some packages that cover several of these +points such as the \pkgname{preview}\cite{preview}, \pkgname{xcomment}\cite{xcomment}, \pkgname{extract}\cite{extract} +and \pkgname{cachepic}\cite{cachepic} packages among others, but none covered all points. + +In the network there are some solutions in \texttt{bash} that were able to +extract and convert environments, but in general they presented problems +when the document contained \emph{\enquote{verbatim style}} code or were only +available for \OSsystem{Linux}. + +Analysed the situation the best thing was to create a new \emph{\enquote{script}} that +was able to cover the three points and was multi platform, the union of all +these ideas is born \ltximg. + +This script would not be possible without the great work of Herbert Voß +author of \scriptname{pst2pdf}\footnote{\url{https://ctan.org/pkg/pst2pdf}} +and Heiko Oberdiek author of \scriptname{pdfcrop}\footnote{\url{https://ctan.org/pkg/pdfcrop}}. +Several parts of the code have been taken and adapted from both scripts. + +\section{Requirements for operation} +\label{sec:requirements} + +For the complete operation of \ltximg{} you need to have a modern % +\hologo{TeX} distribution such as \hologo{TeX} Live or \hologo{MiKTeX}, have +a version equal to or greater than \liningnums{5.28} of \prgname{perl}, a +version equal to or greater than \liningnums{9.24} of \prgname{ghostscript}, a +version equal to or greater than \liningnums{1.40} of \scriptname{pdfcrop} +and have a version equal to or greater than \liningnums{0.52} of % +\prgname{poppler-utils}. The distribution of \hologo{TeX} Live 2020 for \OSsystem{Windows} includes % +\ltximg{} and all requirements, \hologo{MiKTeX} users must install the +appropriate software for full operation. + +The script auto detects the \prgname{ghostscript}, but not \prgname{poppler-utils}. +You should keep this in mind if you are using the script directly and not +the version provided in your \hologo{TeX} distribution. + +The script has been tested on \OSsystem{Windows} (v10) and % +\OSsystem{Linux} (fedora 32) using \prgname{ghostscript} % +\liningnums{v9.52}, \prgname{poppler-utils} \liningnums{v0.84}, \prgname{perl} \liningnums{v5.30} +and the standard classes offers by \hologo{LaTeX}: \myclass{book}, +\myclass{report}, \myclass{article} and \myclass{letter}. The \pkgname{preview}\cite{preview} and +\pkgname{pst-pdf}\cite{pst-pdf} packages are required to process the \meta{input file} and if +an \meta{output file} is generated, the \pkgname{graphicx}\cite{graphicx} and \pkgname{grfext}\cite{grfext} +packages will be needed. + +\section{How it works} +\label{sec:howtowork} + +It is important to have a general idea of how the \emph{\enquote{extraction and conversion}} +process works and the requirements that must be fulfilled so +that everything works correctly, for this we must be clear about some +concepts related to how to work with the \meta[cf=optcolor]{input file}, the \meta{verbatim content} +and the \meta{steps process}. + +\section{The input file} +\label{sec:inputfile} + +The \meta[cf=optcolor]{input file} must comply with \emph{certain characteristics} in order to +be processed, the content at the beginning and at the end of the \meta{input +file} is treated in a special way, before \lstinline|\documentclass| and after +\lstinline|\end{document}| can go any type of content, internally the script will +\emph{\enquote{split}} the \meta[cf=optcolor]{input file} at this points. + +If the \meta[cf=optcolor]{input file} contains files using \ics{input}\marg[type=tt]{file} or +\ics{include}\marg[type=tt]{file} these will not be processed, from the side of +the \emph{script} they only represent lines within the file, if you want +them to be processed it is better to use the \scriptname{latexpand}\footnote{\url{https://www.ctan.org/pkg/latexpand}} +first and then process the file. + +Like \ics{input}\marg[type=tt]{file} or \ics{include}\marg[type=tt]{file}, blank lines, vertical spaces and tab +characters are treated literally, for the \emph{script} the \meta[cf=optcolor]{input file} +is just a set of characters, as if it was a simple text file. It is +advisable to format the source code \meta[cf=optcolor]{input file} using utilities such +as \prgname{chktex}\footnote{\url{https://www.ctan.org/pkg/chktex}} and +\scriptname{latexindent}\footnote{\url{https://www.ctan.org/pkg/latexindent}}, especially if you want to +extract the source code of the environments. + +Both \ics{thispagestyle}\marg[type=tt]{style} and \ics{pagestyle}\marg[type=tt]{style} +are treated in a special way by the script, if they do not appear in the +preamble then \ics{pagestyle}\marg[type=tt]{empty} will be added and if they are present +and \marg[type=tt]{style} is different from \marg[type=tt]{empty} this +will be replaced by \marg[type=tt]{empty}. + +This is necessary for the image creation process, it does not affect the \meta{output file}, but +it does affect the \emph{standalone} files. For the script the process of dividing the \meta{input file} into four +parts and then processing them: + +\begin{examplecode}[numbers=left,frame=single] +% Part One: Everything before \documentclass +\documentclass{article} +% Part two: Everything between \documentclass and \begin{document} +\begin{document} +% Part three: : Everything between \begin{document} and \end{document} +\end{document} +% Part Four: Everything after \end{document} +\end{examplecode} + +If for some reason you have an environment \LWenv{filecontens} before \lstinline|\documentclass| or +in the preamble of the \meta{input file} that contains a \emph{sub-document} or \emph{environment} +you want to extract, the script will ignore them. + +\newpage + +\section{Verbatim contents} +\label{sec:verbatim} + +One of the greatest capabilities of this script is to \emph{\enquote{skip}} +the complications that \meta{verbatim content} produces with the extraction +of environments using tools outside the \enquote{\hologo{TeX} world}\footnote{Only \hologo{TeX} can +understand \hologo{TeX}, all other languages and programs are just lines in a file.}. +In order to \emph{\enquote{skip}} the complications, the \meta{verbatim content} is classified into +three types: + +\begin{itemize}[nosep] + \item Verbatim in line. + \item Verbatim standard. + \item Verbatim write. +\end{itemize} + +\subsection{Verbatim in line} +\label{sec:verbatim:inline} + +The small pieces of code written using a \emph{\enquote{verbatim macro}} +are considered \meta{verbatim in line}, such as \lstinline+\verb|+\meta{code}\lstinline+|+ +or \lstinline+\verb*|+\meta{code}\lstinline+|+ or \lstinline+\macro+\marg[type=tt]{code} or +\lstinline+\macro+\oarg[type=tt]{opts}\marg[type=tt]{code}. + +Most \emph{\enquote{verbatim macro}} provide by packages \pkgname{minted}\cite{minted}, % +\pkgname{fancyvrb}\cite{fancyvrb} and \pkgname{listings}\cite{listings} have been tested and are fully +supported. They are automatically detected the \emph{verbatim macro} (including \texttt{\small\bfseries\textcolor{MediumOrchid}{*}} argument) generates by +\ics{newmint} and \ics{newmintinline} and the following list: + +\vspace*{-10pt} +\begin{multicols}{3} +\begin{itemize}[font=\sffamily\small,partopsep=5pt,parsep=5pt,nosep,leftmargin=*] +\small +\item \ics{mint} +\item \ics{spverb} +\item \ics{qverb} +\item \ics{fverb} +\item \ics{verb} +\item \ics{Verb} +\item \ics{lstinline} +\item \ics{pyginline} +\item \ics{pygment} +\item \ics{Scontents} +\item \ics{tcboxverb} +\item \ics{mintinline} +\end{itemize} +\end{multicols} + +Some packages define abbreviated versions for \emph{\enquote{verbatim macro}} as % +\ics{DefineShortVerb}, \ics{lstMakeShortInline} and % +\ics{MakeSpecialShortVerb}, will be detected automatically if are declared +explicitly in \meta[cf=optcolor]{input file}. + +The following consideration should be kept in mind for some packages that +use abbreviations for verbatim macros, such as \pkgname{shortvrb}\cite{doc} or % +\pkgname{doc}\cite{doc} for example in which there is no explicit \lstinline+\macro+ in the +document by means of which the abbreviated form can be detected, for +automatic detection need to find \ics{DefineShortVerb} explicitly to process +it correctly. The solution is quite simple, just add in \meta[cf=optcolor]{input file}: + +\begin{examplecode} +\UndefineShortVerb{\|} +\DefineShortVerb{\|} +\end{examplecode} + +depending on the package you are using. If your \emph{\enquote{verbatim macro}} is not +supported by default or can not detect, use the options described in \ref% +{sec:optline} and \ref{sec:optfile}. + +\subsection{Verbatim standard} +\label{sec:verbatim:std} + +These are the \emph{\enquote{classic}} environments for \emph{\enquote{writing code}} are considered % +\meta{verbatim standard}, such as \LVenv{verbatim} and \LVenv{lstlisting} +environments.

With all these considerations +in mind it is possible to extract and convert environments +from \emph{any file}. + +For example, by adding these lines at the beginning of the file: + +\begin{examplecode}[numbers=left] +% arara: lualatex: { options: [-recorder] } +% arara: lualatex: { options: [-recorder] } +%<*remove> +% ltximg: options: { arara, output = file-out, prefix = tkz} +% +\end{examplecode} + +and run: + +\begin{examplecmd} +[user@machine~:]§ ltximg test.tex +\end{examplecmd} + +Create a \sysdir{./images} directory (if it does not exist) with all extracted +environments converted to image format (\iext{pdf}) in individual files, +an output file \meta[ac=LightSlateGrey,cf=OrangeRed]{file-out.tex} with all exatracted environments +converted to \ics{includegraphics}, a single file \meta[ac=LightSlateGrey,cf=OrangeRed]{test-tkz-all.tex} +with only the extracted environments using \pkgname{preview} package and \prgname*{lualatex} \emph{\enquote{two times}} +for process \meta[ac=LightSlateGrey,cf=OrangeRed]{test.tex} and \meta[ac=LightSlateGrey,cf=OrangeRed]{file-out.tex}. + +Remember that the \meta[cf=optcolor]{input file} and \meta[cf=optcolor]{output file} +will be compiled using the same \enquote{rule}. One \emph{trick} to get around this situation is to use: + +\begin{examplecode}[numbers=left] +%<*remove> +% arara: lualatex: { options: [-recorder] } +% arara: lualatex: { options: [-recorder] } +% arara: halt +% ltximg: options: { arara, output = file-out, prefix = tkz} +% +% arara: xelatex: { options: [-recorder] } +% arara: xelatex: { options: [-recorder] } +\end{examplecode} + +The content betwen \lstinline|%<*remove> ... %| are remove from output file +before compiling. Thus, the output file \meta[ac=LightSlateGrey,cf=OrangeRed]{file-out.tex} will be +compiled using \prgname*{xelatex} \emph{\enquote{two times}}. + +As a final consideration, \ltximg{} passes options to the \pkgname{preview} package and +the \scriptname{pdfcrop} script according to the engine used. When using \cmdopt{arara} it +will \emph{\enquote{try}} to detect the used engine by means of a regular expression, if the +detection fails the default values will be used. + +This does not affect the process of creating \meta{standalone} files and can be prevented by using \cmdopt{noprew} +or \cmdopt{nocrop} at the cost of not having the images cropped. + +In this way we can \meta{compile} and \meta{convert} any document as long as the conditions +of the \meta[cf=optcolor]{input file} are met and the correct \enquote{rule} are used. + +\newpage + +\section{Example usign \texttt{latexmk}} + +If you are a user of \scriptname{latexmk}, another great utility that automates the compilation process, you must keep +in mind that this will run only in the \meta{output file}.

Generates a file with only extracted environments -and another with environments converted to \ics{includegraphics}. -\end{abstract} - -\tableofcontents -\setlength{\parskip}{3pt} - -\section{Motivation} - -The original idea was to extend the functionality of the \scriptname{pst2pdf} -script (only for \env{pspicture} and \env{postscript}) to work with % -\env{tikzpicture} and other environments. - -The \pkgname{tikz} package allows to externalize the environments, but, the -idea was to be able to extend this to any type of environment covering three -central points: - -\begin{enumerate}[font=\small , noitemsep,leftmargin=*] - -\item Generate separate files for environments and converted into images. - -\item Generate a file with only the extracted environments. - -\item Generate a file replacing the environments by \ics{includegraphics}. -\end{enumerate} - -From the side of \TeX{} there are some packages that cover several of these -points such as the \pkgname{preview}, \pkgname{xcomment}, \pkgname{external} -and \pkgname{cachepic} packages among others, but none covered all points. - -In the network there are some solutions in \texttt{bash} that were able to -extract and convert environments, but in general they presented problems -when the document contained \emph{verbatim style} code or were only -available for \OSsystem{Linux}. - -Analysed the situation the best thing was to create a new \emph{script} that -was able to cover the three points and was multi platform, the union of all -these ideas is born \ltximg. Finding the correct \emph{regular expressions} -and writing \emph{documentation} would be the great mission (which does not -end yet). - -\thispagestyle{plain} -\newpage -\pagestyle{myheader} -\section{Required Software}\label{sec:software} - -For the complete operation of \ltximg{} you need to have a modern % -\hologo{TeX} distribution such as \hologo{TeX}Live or \hologo{MiKTeX}, have -a version equal to or greater than \liningnums{5.28} of \prgname{perl}, a -version equal to or greater than \liningnums{9.24} of \prgname{ghostscript} -and have a version equal to or greater than \liningnums{0.52} of % -\prgname{poppler-utils}. - -The distribution of \hologo{TeX}Live 2019 for \OSsystem{Windows} includes % -\ltximg{} and all requirements, \hologo{MiKTeX} users must install the -appropriate software for full operation. - -The script has been tested on \OSsystem{Windows} (version 10) and % -\OSsystem{Linux} (fedora 30) in x64 architecture using \prgname{ghostscript} % -\liningnums{v9.26}, \prgname{poppler-utils} \liningnums{v0.52} to % -\liningnums{v0.73} and \prgname{perl} from \liningnums{v5.28} to % -\liningnums{v5.30}. - -\section{How it works} - -\label{sec:howtowork} - -It is important to have a general idea of how the \emph{extraction and -conversion} process works and the requirements that must be fulfilled so -that everything works correctly, for this we must be clear about some -concepts related to how to work with the \meta{verbatim content}, the % -\meta{input file}, the \meta{output file} and the \meta{steps process}. - -\subsection{The input file} - -\label{sec:inputfile} - -The \meta{input file} must comply with certain characteristics in order to -be processed, the content at the beginning and at the end of the \meta{input -file} is treated in a special way, before \lstinline|\documentclass| can only be -commented lines and after \lstinline|\end{document}| can go any type of content, -internally will split the \meta{input file} at this points. - -If the \meta{input file} contains files using \ics{input} or \ics{include} -these will not be processed, from the side of the \emph{script} they only -represent lines within the file, if you want them to be processed it is -better to use the \scriptname{latexpand} first and then process the file. - -Like \ics{input} or \ics{include}, blank lines, vertical spaces and tab -characters are treated literally, for the \emph{script} the \meta{input file} -is just a set of characters, as if it was a simple text file. It is -advisable to format the source code \meta{input file} using utilities such -as \prgname{chktex} and \scriptname{latexindent}, especially if you want to -extract the source code of the environments. - -An example of the \meta{input file}: - -\begin{examplecode}[numbers=left,frame=single] -% some commented lines at begin document -\documentclass{article} -\usepackage{tikz} -\begin{document} -Some text -\begin{tikzpicture} -Some code -\end{tikzpicture} -Always use \verb|\begin{tikzpicture}| -and \verb|\end{tikzpicture}| to open -and close environment -\begin{tikzpicture} -Some code -\end{tikzpicture} -Some text -\end{document} -% some lines after end document -\end{examplecode} - -\subsection{Verbatim contents}\label{sec:verbatim} - -One of the greatest capabilities of \ltximg{} script is to skip the complications -that \emph{verbatim style} content produces with the extraction of environments. -In order to skip the complications, the verbatim content is classified into -three types: - -\begin{itemize}[nosep] - \item Verbatim in line - \item Verbatim standard - \item Verbatim write -\end{itemize} - -Each of these classifications works differently within the creation and -extraction process using different regular expressions for it. - -\newpage - -\subsubsection{Verbatim in line} - -\label{sec:verbatim:inline} - -The small pieces of code written in the same line using a verbatim command -are considered \meta{verbatim in line}, such as \lstinline+\verb||+. -Most verbatim commands provide by packages \pkgname{minted}, % -\pkgname{fancyvrb} and \pkgname{listings} have been tested and are fully -supported. They are automatically detected the verbatim command generates by -\ics{newmint} and \ics{newmintinline} and the following command list: - -\begin{multicols}{3} -\begin{itemize}[font=\sffamily\small,partopsep=5pt,parsep=5pt,nosep,leftmargin=*] -\small -\item \ics{mint} -\item \ics{spverb} -\item \ics{qverb} -\item \ics{fverb} -\item \ics{verb} -\item \ics{Verb} -\item \ics{lstinline} -\item \ics{pyginline} -\item \ics{pygment} -\item \ics{Scontents} -\item \ics{tcboxverb} -\item \ics{mintinline} -\end{itemize} -\end{multicols} - -Some packages define abbreviated versions for verbatim commands as % -\ics{DefineShortVerb}, \ics{lstMakeShortInline} and % -\ics{MakeSpecialShortVerb}, will be detected automatically if are declared -explicitly in \meta{input file}. - -The following consideration should be kept in mind for some packages that -use abbreviations for verbatim commands, such as \pkgname{shortvrb} or % -\pkgname{doc} for example in which there is no explicit command in the -document by means of which the abbreviated form can be detected, for -automatic detection need to find \ics{DefineShortVerb} explicitly to process -it correctly. The solution is quite simple, just add in \meta{input file}: - -\begin{examplecode} -\UndefineShortVerb{\|} -\DefineShortVerb{\|} -\end{examplecode} - -depending on the package you are using. If your verbatim command is not -supported by default or can not detect, use the options described in \ref% -{sec:optline} and \ref{sec:optfile}. - -\subsubsection{Verbatim standard} - -\label{sec:verbatim:std} - -These are the classic environments for writing code are considered % -\meta{verbatim standard}, such as \env{verbatim} and \env{lstlisting} -environments.

The following list is considered as % -\meta{verbatim write} environments: - -\begin{multicols}{3} -\begin{itemize}[font=\sffamily\small, noitemsep,leftmargin=*] -\ttfamily\small -\item scontents -\item filecontents -\item tcboutputlisting -\item tcbexternal -\item tcbwritetmp -\item extcolorbox -\item extikzpicture -\item VerbatimOut -\item verbatimwrite -\item filecontentsdef -\item filecontentshere -\item filecontentsdefmacro -\end{itemize} -\end{multicols} - -They are automatically detected \meta{verbatim write} environments generates -by commands: - -\begin{multicols}{2} -\begin{itemize}[font=\sffamily\small, noitemsep,leftmargin=*] -\small -\item \ics{renewtcbexternalizetcolorbox} -\item \ics{renewtcbexternalizeenvironment} -\item \ics{newtcbexternalizeenvironment} -\item \ics{newtcbexternalizetcolorbox} -\end{itemize} -\end{multicols} - -If any of the \meta{verbatim write} environments is not supported by default -or can not detected, you can use the options described in \ref{sec:optline} -and \ref{sec:optfile}. - -\subsection{Steps process} - -\label{sec:steps:process} - -For creation of the image formats, extraction of code and creation of an -output file, \ltximg{} need a various steps. Let's assume that the % -\meta{input file} is \sysfile{test.tex}, \meta{output file} is % -\sysfile{test-out}, the working directory are \sysdir{workdir}, the -directory for images are \sysdir{workdir/images} and the user's temporary -directory is \sysdir{tmp} and we want to generate images in \iext{pdf} -format together with the source codes of the environments. - -\begin{description}[font=\sffamily\small,leftmargin=0em,style=nextline] -\item[Comment and ignore] -The first step is read and validated \oarg[type=rm,cf=gray,sbc=optcolor,ac=gray]{options} from the command -line and \sysfile{test.tex}, verifying that \sysfile{test.tex}, \sysfile{test-out} and the -directory \sysdir{images} are in \sysdir{workdir}, create the directory \sysdir{workdir/images} if it does -not exist and a temporary directory \sysdir{tmp/hG45uVklv9}. The entire file \sysfile{test.tex} is loaded -in memory and proceeds (in general terms) as follows: - -\begin{quotation} -Search the words \lstinline|\begin{| and \lstinline|\end{| in verbatim standard, verbatim write, verbatim in line and -commented lines, if it finds them, converts to \lstinline|\BEGIN{| and \lstinline|\END{|, then places all code to -extract inside the \lstinline|\begin{preview}| \ldots \lstinline|\end{preview}|. -\end{quotation} - -At this point all the code you want to extract is inside \lstinline|\begin{preview}| \ldots \lstinline|\end{preview}| -and the files \sysfile{test-fig-1.tex}, \sysfile{test-fig-2.tex}, \ldots{} are generated and saved in \sysdir{images}. - -\item[Create random file] -In the second step, with the file already loaded in memory, creating a temporary file with a -random number (1981 for example) and proceed in two ways according to the \oarg[type=rm,cf=gray,sbc=optcolor,ac=gray]{options} -passed to the script: - -\begin{enumerate} -\item If script is call \emph{whitout} \cmdopt[n]{noprew} options, adds the -following lines to the beginning of the \sysfile{test.tex} (in memory): - -\begin{examplecode} -\AtBeginDocument{% -\RequirePackage[active,tightpage]{preview} -\renewcommand\PreviewBbAdjust{-60pt -60pt 60pt 60pt}}% -% rest of input file -\end{examplecode} -And save in a temporary file \sysfile{test-fig-1981.tex} in \sysdir{workdir}. - -\item If script is call \emph{whit} \cmdopt[n]{noprew} options, all code to extract -its put inside the \env{preview} environment. The \lstinline|\begin{preview}|\ldots \lstinline|\end{preview}| -lines are only used as delimiters for extracting the content \emph{without} using the package \pkgname{preview}. - -Creating a temporary file \sysfile{test-fig-1981.tex} in \sysdir{workdir} -whit the same preamble of \sysfile{test.tex} but the body only contains code that you want to extract. -\end{enumerate} - -\item[Generate image formats] -In the third step the script run: -\begin{examplecmd} -[user@machine ~:]§`\small\meta[type=tt,cf=ForestGreen,ac=ForestGreen]{compiler}` -recorder -shell-escape `\small\sysfile{test-fig-1981.tex}` -\end{examplecmd} -generating the file \sysfile{test-fig-1981.pdf} whit all code extracted, move \sysfile{test-fig-1981.pdf} -to \sysdir{tmp/hG45uVklv9}, separate in individual files \sysfile{test-fig-1.pdf}, \sysfile{test-fig-2.pdf}, \ldots{} -and copy to \sysdir{workdir/images/}. The file \sysfile{test-fig-1981.tex} is moved to the \sysdir{workdir/images/} -and rename to \sysfile{test-fig-all.tex}. - -Note the options passed to \meta[type=tt,cf=ForestGreen,ac=ForestGreen]{compiler} does not include \prgopt*{output-directory} -(it is not supported) and always use \prgopt*{recorder} \prgopt*{shell-escape} you must keep this in mind if you use \prgname{arara}. - -\item[Create output file] -In the fourth step the script creates the output file \sysfile{test-out.tex} converting all extracted code to -\ics{includegraphics} and adding the following lines at end of preamble: - -\begin{examplecode}[numbers=left] -\usepackage{graphicx} -\graphicspath{{images/}} -\usepackage{grfext} -\PrependGraphicsExtensions*{.pdf} -\end{examplecode} - -If the packages \pkgname{graphicx} and \pkgname{grfext} are already loaded and the command \ics{graphicspath} -is found in the input file were detected automatically and only the changes will be added then proceed to run: -\begin{examplecmd} -[user@machine ~:]§`\small\meta[type=tt,cf=ForestGreen,ac=ForestGreen]{compiler}` -recorder -shell-escape `\small\sysfile{test-out.tex}` -\end{examplecmd} -generating the file \sysfile{test-out.pdf}. -\end{description} -Now the script read the files \sysfile{test-fig-1981.fls} and \sysfile{test-out.fls}, extract the information from the -temporary files generated in the process and then delete them together with the directory \sysdir{tmp/hG45uVklv9}. -An example for input and output file: - -\begin{minipage}[c]{0.5\textwidth} -\begin{examplecode}[numbers=left] -\documentclass{article} -\usepackage{tikz} -\begin{document} -Some text -\begin{tikzpicture} -Some code -\end{tikzpicture} -Always use \verb|\begin{tikzpicture}| -and \verb|\end{tikzpicture}| to open -and close environment -\begin{tikzpicture} -some code -\end{tikzpicture} -Some text -\end{document} -\end{examplecode} -\begin{flushleft} -\sysfile{test.tex} -\end{flushleft} -\end{minipage} -\begin{minipage}[c]{0.5\textwidth} -\begin{examplecode}[numbers=left] -\documentclass{article} -\usepackage{tikz} -\usepackage{graphicx} -\graphicspath{{images/}} -\usepackage{grfext} -\PrependGraphicsExtensions*{.pdf} -\begin{document} -Some text -\includegraphics[scale=1]{test-fig-1} -Always use \verb|\begin{tikzpicture}| -and \verb|\end{tikzpicture}| to open -and close environment -\includegraphics[scale=1]{test-fig-2} -Some text -\end{document} -\end{examplecode} -\begin{flushleft} -\sysfile{test-out.tex} -\end{flushleft} -\end{minipage} - -\section{Extract content} -\label{sec:extract} -The script provides two ways to extract content from \meta{input file}, using \meta[type=rm,cf=optcolor,ac=gray]{environments} -and \meta[type=rm,cf=optcolor,ac=gray]{docstrip tags}.
