banana-checker

Checker for the 'Banana' JSON-file format for interface messages, as used by MediaWiki and jQuery.i18n.

By default, Banana checker asserts the following:

  • The source and documentation files must exist and contain valid JSON.
  • Both files include a @metadata object.
  • Each defined source message is documented.
  • Each defined documentation entry has a matching source message.

For all available options, see the Options section.

You can use Banana checker standalone or as a Grunt plugin.

Getting started (Grunt plugin)

To use this plugin, add it as a development dependency to your project:

npm install grunt-banana-checker --save-dev

Ensure your project has a Gruntfile.js file (example file). Then, in Gruntfile.js, add the line:

grunt.loadNpmTasks( 'grunt-banana-checker' );

Configure the Grunt plugin

In Gruntfile.js, add a configuration key for banana and set it to an empty object.

We will use this object to declare which directory contains the interface messages. For example, to enable grunt-banana-checker for a single directory only, configure it like so:

grunt.initConfig( {
	banana: {
	    all: 'i18n/'
	}
} );

You can also configure multiple directories, like so:

grunt.initConfig( {
	banana: {
	    core: 'languages/i18n/',
	    installer: 'includes/installer/i18n/'
	}
} );

You can also use globbing patterns and/or arrays of directories, like so:

grunt.initConfig( {
	banana: {
	    all: 'modules/ve-{mw,wmf}/i18n/'
	}
} );

For a full list of supported ways of defining the target directory of a Grunt plugin, see Configuring tasks on gruntjs.com.

To customise the options for Banana checker, define your target directory as an object instead of a string, with src and options properties, like so:

grunt.initConfig( {
	banana: {
		all: {
			src: 'i18n/',
			options: {
				sourceFile: 'messages.json',
				documentationFile: 'documentation.json'
			}
		}
	}
} );

For all available options, see the Options section.

Command-line

The Banana checker also offers a command-line interface.

npm install grunt-banana-checker --save-dev

To use Banana checker as part of your test run, refer to the banana-checker program from the scripts.test property in your package.json file.

{
	"scripts": {
		"test": "banana-checker i18n/"
	}
}

To set custom options, pass parameters as --key=value pairs. For example:

npx banana-checker --requireKeyPrefix="x-" i18n/
  • For boolean options, use the valus 0, 1, true, or false.
  • Quotes are allowed, but not required.
  • For options that allow multiple values, separate values by comma. Like --key=one,two.
