Generate Yii translation message files

Question

I am interested to know is there a script or otherway available to collect and generate Yii translation messages in a controller/project

Eg. If I have the following code

Answer 1

That sounds like a job for grep and a regular expression. Search for this:

Yii::t\s*\(\s*('(?:[^']|(?<=\\)')*'|"(?:[^"]|(?<=\\)")*")\s*,\s*('(?:[^']|(?<=\\)')*'|"(?:[^"]|(?<=\\)")*")\s*\)

Since the above is unfortunately unreadable, I 'll break it down a bit:

Yii::t\s*\(\s*##PATTERN##\s*,\s*##PATTERN##\s*\)

This obviously matches a call to Yii::t taking care to account for whitespace. The secret sauce is ##PATTERN##, which is repeated twice. ##PATTERN## is

('(?:[^']|(?<=\\)')*'|"(?:[^"]|(?<=\\)")*")

The above matches either '([^']|(?<=\\)')*' (a singly quoted string) or "([^"]|(?<=\\)")*" (a doubly quoted string). Non-capturing groups (?:) have been used to disregard interim results that are of no interest.

After matching with this regex, capturing group #1 will hold the translation file name (e.g. 'blog') and group #2 will hold the string name (e.g. 'Your name').
