composer-plugin
===============

[](#composer-plugin)

This is a custom installer plugin for Composer to help with WordPress translation of Composer libraries intended for use as shared code in plugins and themes.

When this plugin is installed, libraries with `type` set to `jetpack-library` will be installed into `jetpack_vendor/` instead of the usual `vendor/`. Also translation text domain information will be collected from such libraries and written to `jetpack_vendor/i18n-map.php`.

Use in a WordPress plugin or theme
----------------------------------

[](#use-in-a-wordpress-plugin-or-theme)

This plugin needs to be put into the `require` section of your `composer.json` file in order to be used.

```
	"require": {
		"automattic/jetpack-composer-plugin": "*"
	},
```

You'll also want to set `extra.wp-plugin-slug` or `extra.wp-theme-slug` to the WordPress.org slug, which is also the textdomain for your plugin or theme's translations.

```
	"extra": {
		"wp-plugin-slug": "my-plugin"
	},
```

Finally, for the libraries' translations to work, you'll also want to require [automattic/jetpack-assets](https://packagist.org/packages/automattic/jetpack-assets)and include something like the following in your initialization code just after you load the autoloader:

```
\Automattic\Jetpack\Assets::alias_textdomains_from_file( __DIR__ . '/jetpack_vendor/i18n-map.php' );
```

Use by a library
----------------

[](#use-by-a-library)

A library that wants to be used in WordPress plugins or themes needs to set the `type` in `composer.json` to `jetpack-library`. The library package *should not* itself include a dependency on automattic/jetpack-composer-plugin, although it may [suggest](https://getcomposer.org/doc/04-schema.md#suggest) it.

All calls to `__()`, `_x()`, and other WordPress i18n functions should then use a textdomain unique to the library. This textdomain also needs to be declared in `composer.json` as `extra.textdomain`:

```
	"extra": {
		"textdomain": "my-library"
	},
```
