Convert gettext PO files to JSON to use in your javascript app, based on
po2json.pl by [DuckDuckGo, Inc.](http://duckduckgo.com/). 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](http://slexaxton.github.io/Jed/)


## Versions

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

## Installation

```ruby
gem 'po_to_json', '~> 3.0.2'
```

## Versioning

This library aims to adhere to [Semantic Versioning 2.0.0][semver]. 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][pvc] with two digits of precision.

For example:

```ruby
spec.add_dependency 'po_to_json', '~> 3.0.2'
```

## Usage

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

```ruby
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:

```ruby
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:

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