Prettier Pug plugin
Intro
Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary.
This plugin adds support for the Pug language to Prettier.
Getting started
Simply install prettier
and @prettier/plugin-pug
as your project’s devDependencies
:
npm add --save-dev prettier @prettier/plugin-pug
yarn add --dev prettier @prettier/plugin-pug
pnpm add --save-dev prettier @prettier/plugin-pug
Usage
npx prettier --write "**/*.pug"
yarn prettier --write "**/*.pug"
pnpm prettier --write "**/*.pug"
Configuration
See documentation
Workaround / Known Issue
There are some code examples that are not formatted well with this plugin and can damage your code.
But there are workarounds for it. These generate even better pug code!
Example
Issue 114
If you have tags at the top/root that are indented, they will lose indentation due to a technical limitation of pug.
Please check these before committing after running this plugin for the first time and fix them manually.
Integration with editors
If you are using a text editor that supports Prettier integration (e.g. Atom), you can have all Prettier perks for your Pug code too!
Use VSCode extension to get support for VSCode.
In order to get @prettier/plugin-pug
working in projects that do not have local npm dependencies, you can install this plugin globally:
npm install --global prettier @prettier/plugin-pug
In this case, you might need to check the settings of your editor’s Prettier extension to make sure that a globally installed Prettier is used when it is not found in project dependencies (i.e. package.json
).
Nevertheless, it is recommended to rely on local copies of prettier
and @prettier/plugin-pug
as this reduces the chance of formatting conflicts between project collaborators.
This may happen if different global versions of Prettier or its Pug plugin are used.
Installing @prettier/plugin-pug
either locally or globally may require you to restart the editor if formatting does not work right away.
Implementation details
This plugin is written in TypeScript and its quality is maintained using Prettier and Vitest.

Credits
This project was inspired by https://github.com/gicentre/prettier-plugin-elm.
Many thanks also to @j-f1, @lipis and @azz for the help in transferring this repository to the prettier organization.
Thanks to @Peilonrayz, who gave me the idea to rewrite the printer into a class and thus make the code a lot more maintainable.
Thanks to @lehni, @SkyaTura and @shadowgate15 for the massive contribution and the introduction of many new features into the project.
