The packages

• @prettier/plugin-ruby
• @prettier/plugin-xml
• prettier
• prettier-plugin-nginx
• prettier-plugin-sh
• prettier-plugin-toml

Installation

1. npm install -D -E prettier@3.3.2 prettier-plugin-nginx@1.0.3 @prettier/plugin-ruby@4.0.4 prettier-plugin-toml@2.0.1 @prettier/plugin-xml@3.4.1 prettier-plugin-sh@0.14.0 or probably just pnpm install -D if it’s not your project.
2. If they don’t exist already echo "{}" > .prettierrc && touch .prettierignore
3. pnpm exec prettier . --write or pnpm exec prettier . --check

Configuration

I do with .editorconfig what I can, but for example my template .prettierrc looks like:

{
  "plugins": [
    "@prettier/plugin-ruby",
    "@prettier/plugin-xml",
    "prettier-plugin-nginx",
    "prettier-plugin-sh",
    "prettier-plugin-toml"
  ],
  "overrides": [
    { "files": ".prettierrc", "options": { "parser": "json" } },
    {
      "files": "conf/librewolf.overrides.cfg",
      "options": { "parser": "javascript" }
    }
  ]
}

at the time of writing. It’s directly from documentation excluding the plugin names, but I will want it everywhere.

.pre-commit-config.yaml

This is the file that controls pre-commits behaviour.

Offline

I accidentally wrote this while updating this page to reflect me using prettier outside of pre-commit too nowadays. This has the advantage that the same local environment gets reused and dependencies are managed centrally, but assumes everyone uses pnpm, won’t work in pre-commit ci and may have other issues I am not thinking of as a not-coder myself.
