Texworks 和 texmf.cnf（导出命令？）

Texworks 和 texmf.cnf（导出命令？）

我texmf.cnf在 上创建了一个文件。我在源 shell 文件 (和) 中~\texmf\mytexncf\添加了导出命令。然后我运行了。export TEXMFCNF=~/texmf/mytexcnf:.bashrc.zshrctexhash

当我从 shell 执行编译时，我没有遇到任何问题。但是当我从 texworks 编译时，我的texmf.cnf似乎没有被 latex 命令 (pdflatex) 考虑在内。我尝试在.shrc命令中添加导出命令，但它不起作用。

texworks 执行的是什么 shell？

语境：我编辑了非常大的 tikz 图片。这就是我创建该texmf.cnf文件的原因。

texhash如果您使用的是 TeX Live，则在将文件添加到个人树时无需运行。但是，我不会texmf.cnf在那里添加您的自定义。TeXworks 可能会启动一个新的 shell 来进行编译运行，而这个 shell 可能不会读取~/.bashrc。

更好的办法是将文件创建在 TeX 安装默认会查找的位置。例如，在 TeX Live 上，请阅读 顶部的注释texmf-dist/web2c/texmf.cnf。在 Unix 类型的系统（例如 Mac OS X、GNU/Linux、BSD 等）上，您可以使用 获取文件的完整路径$(kpsewhich -var TEXMFMAIN)/web2c/texmf.cnf。在我的系统上，例如

echo $(kpsewhich -var TEXMFMAIN)/web2c/texmf.cnf

返回

/usr/local/texlive/2015/texmf-dist/web2c/texmf.cnf

此文件包含如何以及在何处包含已修改设置的说明。例如，我的文件是这样的：

% 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/2015/texmf-dist/web2c/texmf.cnf,
% add your custom settings to /some/path/to/texlive/2015/texmf.cnf.
% 
% What follows is a super-summary of what this .cnf file can
% contain. Please read the Kpathsea manual for more information.
%
% 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.
% Long lines can be continued with a \.
%
% 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.  We make extensive
% use of this.

按照这些说明，我所做的修改$(kpsewhich -var TEXMFMAIN)/../texmf.cnf包括以下标题：

% (Public domain.)
% This texmf.cnf file should contain only your personal changes from the
% original texmf.cnf (for example, as chosen in the installer).
%
% That is, if you need to make changes to texmf.cnf, put your custom
% settings in this file, which is .../texlive/YYYY/texmf.cnf, rather than
% the distributed file (which is .../texlive/YYYY/texmf-dist/web2c/texmf.cnf).
% And include *only* your changed values, not a copy of the whole thing!
%

接下来是我想要修改的位的设置：

%%
% ref.: norbert's answer at http://tex.stackexchange.com/a/262265/
TEXMFARCH = /usr/share/texmf
TEXMF = {$TEXMFCONFIG,$TEXMFVAR,$TEXMFHOME,!!$TEXMFSYSCONFIG,!!$TEXMFSYSVAR,!!$TEXMFLOCAL,!!$TEXMFDIST,$TEXMFARCH}
TEXMFDBS = {!!$TEXMFSYSCONFIG,!!$TEXMFSYSVAR,!!$TEXMFLOCAL,!!$TEXMFDIST,$TEXMFARCH}

无论您是从命令行还是从 TeXworks 等编辑器内部进行编译，这都应该可以正常工作。
