How to generate translation file (.po, .xliff, .yml,…) from a Symfony2/Silex project?

Question

Im going to build a Silex/Symfony2 project and I have been looking around for a method to generate XLIFF/PO/YAML translation files based on texts-to-be-translated inside the pro

Workaround for busy people (UNIX)

You can run the following command in the Terminal:

$ grep -rEo --no-filename "'.+'\|\btrans\b" templates/ > output.txt

This will output the list of messages to translate:

'Please provide your email'|trans
'Phone'|trans
'Please provide your phone number'|trans
...

I mean almost.. But you can usually do some work from here...

Obviously you must tweak the command to your liking (transchoice, double-quotes instead of single...).

Not ideal but can help!

grep options

• grep -R, -r, --recursive: Read all files under each directory, recursively this is equivalent to the -d recurse option.
• grep -E, --extended-regexp: Interpret PATTERN as an extended regular expression.
• grep -o, --only-matching: Show only the part of a matching line that matches PATTERN.
• grep -h, --no-filename: Suppress the prefixing of filenames on output when multiple files are searched.
