Visual Studio Code

Integration with VS Code is provided by the LaTeX Workshop extension. You will need to first install tex-fmt through one of the above methods.

Usage

tex-fmt file.tex             # format file.tex and overwrite
tex-fmt --check file.tex     # check if file.tex is correctly formatted
tex-fmt --print file.tex     # format file.tex and print to STDOUT
tex-fmt --keep file.tex      # do not wrap long lines
tex-fmt --stdin              # read from STDIN and print to STDOUT
tex-fmt --help               # view help information

Disabling the formatter

Ending a source line with % tex-fmt: skip disables formatting 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.
