tex-fmt is a fast LaTeX source code formatter written in Rust that standardizes indentation and whitespace in .tex files. It ensures consistent formatting across documents and teams by applying configurable indentation rules to LaTeX environments, commands, and structures.
The -w flag writes changes in place, while --check mode verifies formatting without modifying files, making it suitable for CI pipelines. Configuration can be provided via a TOML file to customize indentation width, tab handling, and other style preferences.
