Localizing package metadata in Extension Manager

[jasonsanjose]

Extension manager and the package.json format https://github.com/adobe/brackets/wiki/Extension-package-format can't currently display locale specific metadata.

In order to meet specific translation needs per country, we need to display localized strings in the ExtensionManagerView for the following properties:

• title - may not be applicable for trademarked names? e.g. Photoshop Express
• description
• keywords - for translated search

This is not to be confused with the current i18n property which describes which languages the extension has been localized in.

A few different straw-man proposals:

1. Add locale specific strings as sibling properties, e.g. "description.fr": "Fichier introuvable"
2. Add locale as a top-level property in the package format: "fr": { "description": "Fichier introuvable" }
3. By convention, check for nls/<locale>/package.json in extension (would require Extension Manager to do additional work for each extension to inspect zip contents)

Unfortunately, there's no precedent to follow in the NPM package format for translated metadata http://npmjs.org/doc/json.html.

FBNC -- @bchintx do you want to verify with a 'real' extension before closing?
