Hi,
While reading a bug pointed by the i18n triage https://bugzilla.wikimedia.org/show_bug.cgi?id=16026, Happy-melon says "A more general bug (which might well exist, I didn't check thoroughly) would be "ALL MediaWiki messages should be either plaintext or accept wikimarkup."
So I had the idea of censusing the wfMsg calls in the MW code and try to detect which ones accept wikimarkup or other dialects (it depends of the wfMsg function and of the parameters of that function). So I wrote yesterday a Python script to census the wfMsg calls in one side and the messages in another side. The latter is not very useful in fact but the former gives some interesting results.
I’ve done some statistics about the wfMsg calls on http://www.mediawiki.org/wiki/WfMsg_statistics. There are also the raw data and the link to the script (output to CSV).
If you find it useful I would be happy, but it was also an exercise for extracting and manipulating data.
