markup_fmt
markup_fmt is a configurable HTML, Vue, Svelte, Astro, Angular, Jinja, Twig, Nunjucks, Vento, Mustache, Handlebars and XML formatter.
Notes for Vue and Svelte Users
This formatter provides some options such as vBindStyle, vOnStyle and more for Vue and
svelteAttrShorthand and svelteDirectiveShorthand for Svelte.
It's recommended to enable these options in this formatter and disable the corresponding rules in eslint-plugin-vue and eslint-plugin-svelte if you used. This will make ESLint faster because less rules will be executed.
Getting Started
dprint
We've provided dprint integration.
This plugin only formats HTML syntax of your HTML, Vue, Svelte, Astro, Angular, Jinja, Twig, Nunjucks, Vento, Mustache, Handlebars and XML files.
You also need other dprint plugins to format the code in <script> and <style> tags.
You can use dprint-plugin-typescript to
format TypeScript/JavaScript code and Malva to format CSS/SCSS/Sass/Less code.
Run the commands below to add plugins:
dprint config add g-plane/markup_fmt
dprint config add g-plane/malva
dprint config add typescript
If you also want to format JSON in <script> tag whose "type" is "importmap", "application/json", or "application/ld+json",
you can add dprint-plugin-json:
dprint config add json
If you want to format Jinja, it's recommended to add Pretty Jinja dprint plugin as well.
After adding the dprint plugins, update your dprint.json and add configuration:
{
// ...
"plugins": [
// ... other plugins URL
"https://plugins.dprint.dev/g-plane/markup_fmt-v0.27.3.wasm"
],
"markup": { // <-- the key name here is "markup", not "markup_fmt"
// config comes here
}
}
You can also read dprint CLI documentation for using dprint to format files.
Use as a Rust crate
