prettier-plugin-pretext v1.0.3

prettier-plugin-pretext

prettier-plugin-pretext is a prettier plugin for PreTeXt XML dialect. prettier is an opinionated code formatter that supports multiple languages and integrates with most editors. The idea is to eliminate discussions of style in code review and allow developers to get back to thinking about code design instead. It is based off of @prettier/plugin-xml.

Getting started

To run prettier with the XML plugin, you're going to need node.

If you're using the npm CLI, then add the plugin by:

npm install --save-dev prettier @prettier/plugin-xml

Or if you're using yarn, then add the plugin by:

yarn add --dev prettier @prettier/plugin-xml

The prettier executable is now installed and ready for use:

./node_modules/.bin/prettier --write '**/*.xml'

Configuration

Below are the options (from src/plugin.ts) that @prettier/plugin-xml currently supports:

Any of these can be added to your existing prettier configuration file. For example:

{
    "tabWidth": 4
}

Or, they can be passed to prettier as arguments:

prettier --tab-width 4 --write '**/*.ptx'

Whitespace

In XML, by default, all whitespace inside elements has semantic meaning. This plugin uses assumptions about the PreTeXt schema to insert/delete whitespace to assist in pretty printing. However, some xml elements are treated specially (for example, elements that contain code). A list of these can be found in src/pretext/special-nodes.

Ignore ranges

You can use two special comments to get prettier to ignore formatting a specific piece of the document, as in the following example:

<foo>
  <!-- prettier-ignore-start -->
    <this-content-will-not-be-formatted     />
  <!-- prettier-ignore-end -->
</foo>
