Chronic

Chronic is a natural language date/time parser written in pure Ruby. Chronic L10n aims to add translations to Chronics abilities.

WARNING: This gem will only work when and IF this fork of chronic gets merged and released. Meanwhile you can install the chronic gem from the forks source to get it going.

$ [sudo] gem install chronic-l10n

$ git clone git://github.com/luan/chronic-l10n.git
$ cd chronic-l10n && gem build chronic-l10n.gemspec
$ gem install chronic-l10n-<version>.gem

You can parse strings containing a natural language date using the Chronic.parse method.

require 'chronic'
require 'chronic-l10n'

The best way to get your changes merged back into core is as follows:

1. Clone down your fork
2. Create a thoughtfully named topic branch to contain your change
3. Hack away
4. Add tests and make sure everything still passes by running rake
5. Ensure your tests pass in multiple timezones. ie TZ=utc rake TZ=BST rake
6. If you are adding new functionality, document it in the README
7. Do not change the version number, we will do that on our end
8. If necessary, rebase your commits into logical chunks, without errors
9. Push the branch up to GitHub
10. Send a pull request for your branch
