po_to_json

Convert gettext PO files to JSON to use in your javascript app, based on po2json.pl by DuckDuckGo, Inc.. Ideally you'll use this on a Rake task that creates JSON versions of your PO files, which can later be used from javascript with Jed

For a list of the tested and supported Ruby and JSON versions please take a look at the wokflow.

gem 'po_to_json', '~> 2.1.1'

This library aims to adhere to Semantic Versioning 2.0.0. Violations of this scheme should be reported as bugs. Specifically, if a minor or patch version is released that breaks backward compatibility, a new version should be immediately released that restores compatibility. Breaking changes to the public API will only be introduced with new major versions.

As a result of this policy, you can (and should) specify a dependency on this gem using the Pessimistic Version Constraint with two digits of precision.

For example:

spec.add_dependency 'po_to_json', '~> 2.1.1'

Most common use would be to generate a Jed ready javascript file. For example, in a Rails project:

require 'po_to_json'

json = PoToJson.new(
  Rails.root.join('locale', 'de', 'app.po')
).generate_for_jed('de')

Rails.root.join(
  'app',
  'assets',
  'javascripts',
  'locale',
  'de',
  'app.js'
).write(json)

If you need a pretty json, add pretty: true to generate_for_jed, like the following example:

require 'po_to_json'

json = PoToJson.new(
  Rails.root.join('locale', 'de', 'app.po')
).generate_for_jed('de', pretty: true)

Rails.root.join(
  'app',
  'assets',
  'javascripts',
  'locale',
  'de',
  'app.js'
).write(json)

The javascript file generated has a global "locales" object with an attribute corresponding to the generated language:

i18n = new Jed(locales['de'])
i18n.gettext('Hello World') // Should evaluate to 'Hallo Welt'
