coq-tex can pre-process LaTeX files with special environments to put Coq interactions in the output files; the result is ready for use with, say, pdflatex.

I like latexmk, having only recently discovered it, and want it to automatically run coq-tex. How?

Based on latexmk: Multiple custom-generated files and \input, I managed to get the following setup mostly working. Configure latexmk with

add_cus_dep('tex', 'v_tex', 0, 'coqtex');
sub coqtex {
    system("coq-tex -sl \"$_[0].tex\" -o \"$_[0].v_tex\"");
}
push @generated_exts, 'v_tex';

Then, use the following macro to input tex files with the Coq environments:

\newcommand{\inputcoq}[1]{\InputIfFileExists{#1.v_tex}{}{\typeout{No file #1.v_tex.}}}

e.g., \inputcoq{foo}. latexmk should happily regenerate the correct files automatically.

One issue, however, is that neither latexmk -c nor latexmk -C will remove the generated v_tex files. Of secondary concern, coq-tex automatically uses the extension .v.tex, which seemed to choke latexmk when I configure it with add_cus_dep('tex', 'v.tex', 0, 'coqtex'); (and change the rest of the code accordingly). This is because latexmk considers everything after the last dot to be the extension.

  • To get the files generated by custom dependenciess removed when you do a latexmk clean (-c or -C) put the line $cleanup_includes_cusdep_generated = 1; in a configuration file. – John Collins Apr 14 '21 at 19:37
  • About using the extension v.tex: A lot of people define the extension to be what's after the last period, i.e., "tex", and that's the choice made by latexmk. It would need a bit of programming to change that. It's probably better to use v_tex, as you are doing. – John Collins Apr 14 '21 at 19:42
  • @JohnCollins thanks for the insight on the extension; will add. I didn't have to change $cleanup_includes_cusdep_generated for other rules (I have several for glossaries, and this is enough: push @generated_exts, 'glo', 'gls', 'acn', 'acr', 'slo', 'sls', 'ist', 'glg', 'alg', 'slg';), so not sure there – D.

  • The use of @generated_exts is about those files that have the same basename as the tex file. That's why using this variable worked before. The documentation could be clearer about that. – John Collins Apr 15 '21 at 00:17
