Typst formatter
typstfmt
is a formatter for Typst code.
It only formats inputs that are valid Typst code. It aims to make the code consistent.
Install
Cargo
cargo install --git https://github.com/jeffa5/typstfmt
Nix
The flake provides an overlay which you can use with nixpkgs.
Run
# format stdin
typstfmt
# format typst files in current directory
typstfmt *.typ
Nix
nix run github:jeffa5/typstfmt
Configuration
You can configure some aspects of the formatting with a typstfmt.toml
file in the current directory, or specify its location with the --config-path
flag.
The default configuration is:
indent = 2 # spaces
spacing = true # whether to manage spacing
Development
Fuzzing
List some fuzz targets:
cargo fuzz list
Then run one, e.g. for nofmt_unchanged
:
cargo fuzz run nofmt_unchanged
Testing against the package repo
The typst packages
repo is a submodule (typst-packages
).
We can run the formatter against it to check the formatting and for erroneous outputs with:
cargo run -- typst-packages --check
And try to format them all (useful for manual diffing):
cargo run -- typst-packages
Acknowledgements
typstfmt
is a rewrite of typst-fmt
which aims to retain all original text whilst also be able to be flexible in its configuration.
I tried writing some rules for that formatter before beginning the redesign present here.
