latex-runner 1.1.0

Build a LaTeX file.

latex-runner

A wrapper around LaTeX to build files which

• reads magic comments to determine the TeX program and options to be used.
• filters the output to show only errors, warnings, over-/underfull boxes, tracing commands and prompts.
• runs biber and makeglossaries if necessary.
• reruns LaTeX up to -n times if necessary.

Magic Comments

This program supports the following magic comments:

% !TeX root = ../main.tex

Run the TeX program with the given file instead. This is useful if you have split up your document into multiple files, the current file is included in the main file with \input or \include and you have told vim to build the currently opened file with this program.

% !TeX program = pdflatex

The program used to build the tex file.

For security reasons programs not listed in the allowed-tex-programs setting are not executed. By default the allowed programs are pdflatex, xelatex, lualatex, latex, tex and pdftex. You can change these with latex-runner --edit-config.

% !TeX option = -shell-escape

A command line option which should be passed to the TeX program. You can repeat this comment to enable several command line options. I have introduced this type of comment because at the time of this writing % !TeX program = pdflatex -shell-escape breaks compilation in TeX studio.

For security reasons options not listed in the allowed-tex-options setting are not passed to the TeX program. By default the allowed options are --shell-escape, --8bit, --interaction=batchmode, --interaction=nonstopmode, --interaction=scrollmode and --interaction=errorstopmode. You can change these with latex-runner --edit-config.

% !TeX jobname = content:*.tex

The jobname to pass to LaTeX. If this is a glob pattern matching several files the LaTeX file will be built several times, once for each jobname. The file extension is stripped from the jobname. Optionally a path may be specified before, separated by a colon, specifying the directory in which to look for the glob pattern. You can use this magic comment multiple times in order to specify multiple glob patterns or literal jobnames. (This is not a standard comment supported by other programs as well, I have defined it.)

For example, let's assume there is a directory called content next to the main file. This directory contains four files a.tex, b.tex, c.tex and c.log.

• Then % !TeX jobname = content:*.tex causes the main file to be built three times with the jobnames a, b and c, generating three pdf files a.pdf, b.pdf and c.pdf.
• Then % !TeX jobname = content/*.tex causes the main file to be built three times with the jobnames content/a, content/b and content/c, generating three pdf files content/a.pdf, content/b.pdf and content/c.pdf.

You can access the jobname in TeX with the macro \jobname. For example:

• \input{content/\jobname}

• or

  \def\comparejobname{a}
  \edef\expandedjobname{\jobname}
  \ifx\comparejobname\expandedjobname
      This is job a.
  \else
      This is not job a.
  \fi
  

Config

You can change settings with

latex-runner --edit-config

You can get help how to configure this program with

latex-runner --help-config

Installation

You can install this program via the python package manager pipx:

pipx install latex-runner

vim integration

Copy the following into ~/.vim/after/ftplugin/tex.vim. This will allow you to run LaTeX once with F5, build the pdf completely with Control+F5 and open the pdf at the cursor position in zathura with Shift+F5 or F6. You can open the log file with F7.

" build pdf
nnoremap <buffer> <F5> :exec "!latex-runner -n1 -synctex=1 " .. expand('%:p:S')<cr>
nnoremap <buffer> <C-F5> :exec "!latex-runner -n5 -synctex=1 " .. expand('%:p:S')<cr>

" open pdf
nnoremap <buffer> <S-F5> :exec "silent! !zathura --synctex-forward " .. line('.') .. ":" .. col('.') .. ":" .. expand('%:p') .. " " .. trim(system('latex-runner --get-pdf ' .. expand('%:p:S') .. " 2>/dev/null")) .. " >/dev/null 2>/dev/null &"<cr>:redraw!<cr>
nnoremap <buffer> <F6> :exec "silent! !zathura --synctex-forward " .. line('.') .. ":" .. col('.') .. ":" .. expand('%:p') .. " " .. trim(system('latex-runner --get-pdf ' .. expand('%:p:S') .. " 2>/dev/null")) .. " >/dev/null 2>/dev/null &"<cr>:redraw!<cr>

" open log file, return with :bp
nnoremap <buffer> <F7> :exec "edit " .. trim(system('latex-runner --get-log ' .. expand('%:p:S') .. " 2>/dev/null"))<cr>

" texdoc, to be used when cursor is in argument of \usepackage
nnoremap <buffer> K :silent exec '!texdoc <c-r>=expand("<cfile>")<cr> >/dev/null 2>&1 &' \| redraw!<cr>

Running the tests

I am using mypy for static type checking and pytest for dynamic testing. tox creates a virtual environment and installs all dependencies for you. You can install tox with pipx (pipx install tox).

$ tox

In order to make tox work without an internet connection install devpi:

$ pipx install devpi-server
$ devpi-init
$ devpi-gen-config
$ su
# cp gen-config/devpi.service /etc/systemd/system/
# systemctl start devpi.service
# systemctl enable devpi.service

and add the following line to your bashrc:

export PIP_INDEX_URL=http://localhost:3141/root/pypi/+simple/
