On the ServerGrove blog today there's a new post about using their TranslationEditorBundle (Symfony2) to handle multilingual support for your site.
We have been working a lot with Symfony2 translations lately (we translated our website to Spanish and we are in the process of translating our control panel too). Dealing with multiple translation files is not difficult, but it takes time, lots of copy & paste. We have found that is quite easy to make mistakes, create duplicate lines, etc... in short, it’s messy. To tame the translation chaos we decided to create a simple web based editor to deal with Symfony2 translations. The result is the TranslationEditorBundle and it’s publicly available for anyone to use and contribute to.
The bundle gives you a simple web frontend to the translation process, making it a lot simpler to input the different versions of the text as well as determine where any duplication might be happening. It also gives you things like the total number of entries and the number of them missing their translations.
