merged branch clemens-tolboom/pofileloader-better-whitelines (PR #4339)
Commits -------fb6cf3e
Allow for missing whitelines. Discussion ---------- Allow for missing whitelines. The Gettext specification allows for 'whitespace is optional' between message string. For this to work PoFileLoader needs to save found messages on more places while processing. Thus a new method is introduced. For the tests to work PoFileDumper was changed slightly to only emit white-lines when necessary. I added more documentation from the GNU gettext documentation to make the code more understandable. When [[BUG] PoFileLoader pluralhandling uses interval instead of index.](https://github.com/symfony/symfony/pull/4336) this patch needs some small rework. (this is part of [[WIP]: Allow Drupal to use Translate component)](https://github.com/symfony/symfony/pull/4249) --------------------------------------------------------------------------- by travisbot at 2012-05-19T12:44:19Z This pull request [passes](http://travis-ci.org/symfony/symfony/builds/1374295) (mergedfb6cf3ef
