# install from github
cargo install --git "https://github.com/wgunderwood/tex-fmt"

Nix

Usage

tex-fmt file.tex        # format file.tex and overwrite
tex-fmt -c file.tex     # check if file.tex is correctly formatted
tex-fmt -p file.tex     # format file.tex and print to STDOUT
tex-fmt -k file.tex     # keep lines, do not wrap
tex-fmt -h              # view help information

Disabling the formatter

Ending a source line with % tex-fmt: skip disables the formatter for that line. To disable the formatter for a block, use % tex-fmt: off and % tex-fmt: on.

\documentclass{article}

\begin{document}

This line is skipped % tex-fmt: skip

% tex-fmt: off
  These lines are also
    not formatted or wrapped
% tex-fmt: on

\end{document}

Verbatim environments including verbatim, Verbatim, lstlisting and minted are automatically skipped.

Performance

When formatting all of the test cases, tex-fmt is over a thousand times faster than latexindent.
