prettier-plugin-reasonml

library0.2.0jsnpmunverified

A wrapper plugin that adds ReasonML (`.re` files) formatting support to Prettier by delegating to the `refmt` binary. Version 0.2.0 is the current stable release, with no regular cadence. Unlike AST-transforming plugins, this passes code directly to `refmt`, making it a thin integration layer. It requires `refmt` or `bsrefmt` to be installed separately, and inherits Prettier's configured options like `print-width`. Useful for ReasonML projects already using Prettier.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ // No JS import; use via Prettier CLI or API with --plugin

✗ const plugin = require('prettier-plugin-reasonml')

This is a Prettier plugin, not a library. It is loaded automatically by Prettier when installed. No direct import in code.

Install globally and use Prettier CLI to format ReasonML files with custom print width.

npm install -g prettier prettier-plugin-reasonml prettier src/**/*.re --write --print-width 120

Debug

Known issues

gotchaVSCode Prettier extension does not support this plugin due to an upstream issue.

fix

Use CLI or other editor integrations; see https://github.com/prettier/prettier-vscode/issues/395

affects: >=0.1.0

gotchaRequires `refmt` binary in PATH or set via REFMT_BIN environment variable.

fix

Ensure refmt (from reason package) is installed and accessible, or set REFMT_BIN=bsrefmt

affects: >=0.1.0

gotchaUses refmt directly; no AST manipulation, so some Prettier options may not apply as expected.

fix

Only options that translate to refmt flags (e.g., print-width) have effect.

affects: >=0.1.0
