@glimmerx/prettier-plugin-component-templates v0.6.8

@glimmerx/prettier-plugin-component-templates

Background

Prettier is an opinionated code formatter. In Prettier >2.0 there is support for *.hbs glimmer files, but does not support the experimental syntaxes that glimmerx components are authored in.

Introduction

This plugin extends the internal printers to add an embedded syntax for glimmer template in an hbs TaggedTemplateExpressions.

Installation and Usage

yarn add -D @glimmerx/prettier-plugin-component-templates

Once added prettier will discover and use the plugin to format any hbs tagged template expression.

Options

In your prettier config options (e.g. .prettierrc, prettier.config.js, etc.)

.prettierrc

{
  "hbsSingleQuote": true
}

Defaults to false forcing double-quotes for all attributes in an hbs embed. When true will rewrite all quotes to single-quotes.

Development

Generate a test case, add it to the tests file,

Add PRETTIER_DEBUG=true to the environment when running the plugin in order to get complete stack traces on errors.
