% original texmf.cnf -- runtime path configuration file for kpathsea.
% Public domain.
% 
% If you modify this original file, YOUR CHANGES WILL BE LOST when it is
% updated.  Instead, put your changes -- and only your changes, not an
% entire copy! -- in ../../texmf.cnf.  That is, if this file is
% installed in /some/path/to/texlive/2021/texmf-dist/web2c/texmf.cnf,
% put your custom settings in /some/path/to/texlive/2021/texmf.cnf.
% (Below, we use YYYY in place of the specific year.)
% 
% What follows is a super-summary of what this .cnf file can
% contain. Please read the Kpathsea manual for more information.
%
% Each statement in this file boils down to:
%   <variable>[.<program>] [=] <value>
%
% Neither the <variable> nor the <value> may be empty.
% Any identifier (sticking to A-Za-z_ for names is safest) can be assigned.
% The `=' (and surrounding spaces) is optional.
% $foo (or ${foo}) in a value expands to the envvar or cnf value of foo.
% Lines can be continued with a \; no whitespace removal is done.
%
% Earlier entries (in the same or another file) override later ones, and
% an environment variable foo overrides any texmf.cnf definition of foo.
%
% All definitions are read before anything is expanded, so you can use
% variables before they are defined.
%
% If a variable assignment is qualified with `.PROGRAM', it is ignored
% unless the current executable (last filename component of argv[0]) is
% named PROGRAM.  This foo.PROGRAM construct is not recognized on the
% right-hand side. For environment variables, use FOO_PROGRAM.
%
% Which file formats use which paths for searches is described in the
% various programs' and the Kpathsea documentation (http://tug.org/kpathsea).
%
% // means to search subdirectories (recursively).
% A leading !! means to look only in the ls-R db, never on the disk.
% In this file, either ; or : can be used to separate path components.
% A leading/trailing/doubled path separator in the paths will be
%   expanded into the compile-time default. Probably not what you want.
%
% Brace notation is supported, for example: /usr/local/{mytex,othertex}
% expands to /usr/local/mytex:/usr/local/othertex.


%  Part 1: Search paths and directories.

% This is the parent directory of our several trees, i.e.,
% /usr/local/texlive/YYYY in the original TeX Live distribution.
%
% The path definitions here assume the directories are organized
% according to the TeX Directory Structure (http://tug.org/tds).
%
% Redistributors will probably want $SELFAUTODIR/share, i.e., /usr/share.
% Kpathsea sets (in kpathsea/progname.c):
% SELFAUTOLOC (directory of the binary=/usr/local/texlive/YYYY/bin/i386-linux),
% SELFAUTODIR (its parent = /usr/local/texlive/YYYY/bin), 
% SELFAUTOPARENT (its grandparent = /usr/local/texlive/YYYY), and
% SELFAUTOGRANDPARENT (its great-grandparent = /usr/local/texlive).
% Sorry for the off-by-one-generation names.
TEXMFROOT = $SELFAUTOPARENT

% The main tree of distributed packages and programs:
TEXMFDIST = $TEXMFROOT/texmf-dist

% We used to have a separate /texmf tree with some core programs and files.
% Keep the variable name.
TEXMFMAIN = $TEXMFDIST

% Local additions to the distribution trees.
TEXMFLOCAL = $SELFAUTOGRANDPARENT/texmf-local

% TEXMFSYSVAR, where *-sys store cached runtime data.
TEXMFSYSVAR = $TEXMFROOT/texmf-var

% TEXMFSYSCONFIG, where *-sys store configuration data.
TEXMFSYSCONFIG = $TEXMFROOT/texmf-config

% Per-user texmf tree(s) -- organized per the TDS, as usual.  To define
% more than one per-user tree, set this to a list of directories in
% braces, as described above.  (This used to be HOMETEXMF.)  ~ expands
% to %USERPROFILE% on Windows, $HOME otherwise.
TEXMFHOME = ~/texmf

% TEXMFVAR, where texconfig/updmap/fmtutil store cached runtime data.
TEXMFVAR = ~/.texlive2021/texmf-var

% TEXMFCONFIG, where texconfig/updmap/fmtutil store configuration data.
TEXMFCONFIG = ~/.texlive2021/texmf-config

% This is the value manipulated by tlmgr's auxtrees subcommand in the
% root texmf.cnf. Kpathsea warns about a literally empty string for a
% value, hence the empty braces.
TEXMFAUXTREES = {}

% List all the texmf trees. For an explanation of what they are, see the
% TeX Live manual.
%
% For texconfig to work properly, TEXMFCONFIG and TEXMFVAR should be named
% explicitly and before other trees.
% 
% TEXMFLOCAL precedes TEXMFDIST because locally-installed versions
% should take precedence over distribution files -- although it is
% generally a source of confusion to have different versions of a
% package installed, whatever the trees, so try to avoid it.
% 
% The odd-looking $TEXMFAUXTREES$TEXMF... construct is so that if no auxtree is
% ever defined (the 99% common case), no extra elements will be added to
% the search paths. tlmgr takes care to end any value with a trailing comma.
TEXMF = {$TEXMFAUXTREES$TEXMFCONFIG,$TEXMFVAR,$TEXMFHOME,!!$TEXMFLOCAL,!!$TEXMFSYSCONFIG,!!$TEXMFSYSVAR,!!$TEXMFDIST}

% Where to look for, and where mktexlsr creates, ls-R files. By default,
% this is all and only the !! elements of TEXMF, so that mktexlsr does not
% create ls-R files in the non-!! elements -- because if an ls-R is
% present, it will be used, and the disk will not (usually) be searched,
% regardless of !!.  Although in principle a directory listed here need
% not contain an ls-R file, in practice they all should.
TEXMFDBS = {!!$TEXMFLOCAL,!!$TEXMFSYSCONFIG,!!$TEXMFSYSVAR,!!$TEXMFDIST}

% The system trees.  These are the trees that are shared by all users.
% If a tree appears in this list, the mktex* scripts will use
% VARTEXFONTS for generated files, if the original tree isn't writable;
% otherwise the current working directory is used.
SYSTEXMF = $TEXMFSYSVAR;$TEXMFLOCAL;$TEXMFDIST

% First writable tree here is used by Lua(La)TeX for the font cache.
% LuaLaTeX uses the value here, while ConTeXt uses the same variable but
% from texmfcnf.lua; therefore the two values should be kept in sync.
% (As should everything else in texmf.cnf <-> texmfcnf.lua.)
TEXMFCACHE = $TEXMFSYSVAR;$TEXMFVAR

% Where generated fonts may be written.  This tree is used when the sources
% were found in a system tree and either that tree wasn't writable, or the
% varfonts feature was enabled in MT_FEATURES in mktex.cnf.
VARTEXFONTS = $TEXMFVAR/fonts

% On some systems, there will be a system tree which contains all the font
% files that may be created as well as the formats.  For example
%   TEXMFVAR = /var/lib/texmf
% is used in many distros.  In this case, set VARTEXFONTS like this
%VARTEXFONTS = $TEXMFVAR/fonts
% and do not mention it in TEXMFDBS (but _do_ mention TEXMFVAR).
%
% Remove $VARTEXFONTS from TEXMFDBS if the VARTEXFONTS directory is below
% one of the TEXMF directories (avoids overlapping ls-R files).

% WEB2C is for Web2C specific files.  The current directory may not be

WEB2C = $TEXMF/web2c

%% The mktex* scripts rely on KPSE_DOT. Do not set it in the environment.
% KPSE_DOT = .

% This definition isn't used from this .cnf file itself (that would be
% paradoxical), but the compile-time default in paths.h is built from it.
% The SELFAUTO* variables are set automatically from the location of
% argv[0], in kpse_set_program_name.
% 
% This main texmf.cnf file is installed, for a release YYYY, in a
% directory such as /usr/local/texlive/YYYY/texmf-dist/web2c/texmf.cnf.
% Since this file is subject to future updates, the TeX Live installer
% or human administrator may also create a file
% /usr/local/texlive/YYYY/texmf.cnf; any settings in this latter file
% will take precedence over the distributed one.
% 
% For security reasons, it is best not to include . in this path.
%
% The idea behind this lengthy definition: for each of
% SELFAUTO{LOC,DIR,PARENT}, look in the directory,
% then the subdirectories share/texmf-local, share/texmf-dist, share/texmf,
% then the subdirectories ./texmf-local, texmf-dist, ./texmf.
% At any given installation, most of these directories will not exist,
% but they all turn out to be useful somewhere.
% 
% Special addition -- we want to include one more directory: the
% great-grandparent's texmf-local, because that is how TL is installed
% by default.  That is, given a binary
% /usr/local/texlive/YYYY/bin/PLATFORM/kpsewhich, it should find
% /usr/local/texlive/texmf-local/web2c/texmf.cnf.  I.e., not under YYYY.
% 
% As a result, we cannot use actual brace expansion in the definition,
% since we don't want to scatter ../'s throughout the value.  Hence we
% explicitly list every directory.  Arguably more understandable anyway.

% are tried.  The setting applies to all searches, not just .tex.
%
% This setting only affects names being looked up which *already* have
% an extension.  A name without an extension (e.g., `tex story') will
% always have an extension added first.
%

% much, try \tracingstats=2 in your TeX source file;
