Fromager

Fromager helps you format your codebase.

Installation & Usage

If you have Opam, the package manager of OCaml, simply do:

$ opam install fromager
$ fromager

It's that simple! You don't even need an .ocamlformat file.

Configuring Fromager

By default, fromager ignores any directory starting with an underscore (e.g. _opam) or with a dot (e.g. .git).

You can optionally create a fromage.toml file at the root of your project:

[config]
ocamlformat_version = "0.18.0"
ignored_files = []
ignored_dirs = [ "./some", "./ignored/directories" ]

Enforce formatting in CI by adding a Fromager Github action

on:
  [pull_request]
