tex2nix's Introduction

tex2nix

Generate Texlive environment containing all dependencies for your document rather than downloading gigabytes of texlive packages.

Installation

With stable nix you can do:

nix-build && ./result/bin/tex2nix

If you use flakes put the following in your inputs

{
  inputs.tex2nix.url = "github:rgri/tex2nix";
  inputs.tex2nix.inputs.utils.follows = "nixpkgs";
}

or just do:

$ nix run github:rgri/tex2nix

USAGE

$ tex2nix main.tex
wrote tex-env.nix
$ cat tex-env.nix
# Generated with tex2nix 0.0.0
{ texlive }:
(texlive.combine {
    inherit (texlive) scheme-small;
    "varwidth" = texlive."varwidth";
    "tabu" = texlive."tabu";

})

tex2nix does not follow \input or \include. However you can specify multiple texfiles as input

$ tex2nix *.tex

The resulting expression can be imported like this to in your document directory:

# shell.nix
with import <nixpkgs> {};
mkShell {
  buildInputs = [ (pkgs.callPackage ./tex-env.nix {}) ];
}

$ nix-shell shell.nix
nix-shell> pdflatex --version
pdfTeX 3.14159265-2.6-1.40.21 (TeX Live 2020/NixOS.org)
...

To add additional packages you can use the extraTexPackages field:

with import <nixpkgs> {};
mkShell {
  buildInputs = [ (pkgs.callPackage ./tex-env.nix {
    extraTexPackages = {
      inherit (texlive) latexmk;
    };
  }) ];
}

This is caused by the program being wrapped to use nixFlakes and using the nix v2 nix eval command.

I see that you're looking for a new maintainer. I'm new to the OSS and Nix communities and am looking for the chance to gain some experience. Would this project be a good place to start? If so, I'm pretty familiar with latex having used it in school extensively, and I know how to read Nix and use Flakes.

Packages with different style file name are ignored

Given this example document:

\documentclass{article}
\usepackage{MnSymbol}
\begin{document}
 $\bigcircle$
\end{document}

When running tex2nix on it, it does not add the package to the environment.

This is because there is no TeXLive package named MnSymbol, only mnsymbol. However, the style file is called MnSymbol.sty, so using \usepackage{mnsymbol} (for which tex2nix produces the correct environment) does not work.

I don’t know how this could be fixed, because searching the name of the style files would require building all TeXLive packages, which takes a long time and uses up a high amount of storage. In this specific case, a workaround might be to compare the packages case-insensitive, though that might lead to other problems.

find dependencies recursively

recurse into

\input files
\usepackage files
\RequirePackage files
consider [] before {} and that lines may be commented
