tex-fmt – fast LaTeX formatter written in Rust

tex-fmt is a fast, opinionated command-line formatter for LaTeX source.

Written in safe Rust, it applies consistent indentation and line wrapping with little configuration, while retaining controls needed for automated checks and project-specific conventions.

This is free and open source software.

Key Features

• Formats LaTeX-related .tex, .bib, .cls, and .sty files.
• Applies structured indentation to environments, lists, equations, and other common LaTeX constructs.
• Wraps long prose to a configurable target width, with separate minimum and maximum line-length settings.
• Can format table environments by aligning ampersands and inserting appropriate line breaks.
• Formats files in place, checks formatting without changing a file, or prints the proposed result to standard output.
• Reads from standard input, making it straightforward to use in editor integrations, pipes, and scripted workflows.
• Recursively discovers supported files and respects patterns in .gitignore and .ignore.
• Uses TOML configuration at user, Git repository, or working-directory level; command-line arguments take precedence.
• Lets users configure indentation width, tabs or spaces, custom list and verbatim environments, non-indented environments, and wrapping characters.
• Supports line-level and block-level skip directives, and automatically leaves standard verbatim, listing, and minted environments untouched.
• Provides check and fail-on-change modes suited to pre-commit hooks and continuous integration pipelines.
• Generates shell completion scripts and a manual page directly from the command-line interface.
• Offers native Linux binaries for x86-64, AArch64, and ARMv7, plus an Alpine Linux build.
