Prettier for XML

@prettier/plugin-xml is a prettier plugin for XML. 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.

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.js) that @prettier/plugin-xml currently supports:

API Option	CLI Option	Default	Description
`bracketSameLine`	`--bracket-same-line`	`true`	Same as in Prettier (see prettier docs)
`printWidth`	`--print-width`	`80`	Same as in Prettier (see prettier docs).
`tabWidth`	`--tab-width`	`2`	Same as in Prettier (see prettier docs).
`xmlWhitespaceSensitivity`	`--xml-whitespace-sensitivity`	`"strict"`	How to handle whitespaces. Options are `"strict"` and `"ignore"`.

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 '**/*.xml'

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>
