vim-fourmolu

This plugin provides an interface for https://github.com/fourmolu/fourmolu and https://github.com/tweag/ormolu in Vim

Usage

The default behavior of this plugin formats a file when saving, but the FourmoluFmt command can be used to format source manually. Ranges are supported when using FourmoluFmt too. The plugin provides additional commands to enable, disable, or toggle formatting when saving a file using FourmoluWriteOn, FourmoluWriteOff, and FourmoluWriteToggle.

Configuration

If you only want to format content manually setting the following variable to 0 will disable automatic formatting when saving your file:

let g:fourmolu_write = 0

By default the plugin expects to find a fourmolu executable in your PATH but this can be changed by setting:

let g:fourmolu_executable = "ormolu"

Any modifications to fourmolu's formatting should be set in fourmolu.yaml
