This is usually a good incentive for translators: "We are 4th in the
ranking!",
"Oh look, we just passed Greek!", "Careful, at this pace Polish will surpass
us in a week..."

This reminds me that you can get a quick sense of how active a language is by looking at the word cloud at the beginning of [[Special:SupportedLanguages]].

I guess this refers to https://translatewiki.net/wiki/Special:SupportedLanguages , not to any page currently available on Wikimedia wikis?

It's available on all Translate wikis. It was disabled on Wikimedia wikis, see bug 52728.

Kunal, I'm marking this as assigned to you because you showed interest; reset assignee if you're no longer interested.
Kunal discussed this with me and Siebrand separately and we both suggested creating a default message group that would contain all message groups; then this feature would be satisfied by Special:MessageGroupStats without further modifications.

As I noted on IRC, creating an aggregate message group consisting of messages in different namespaces is not currently possible. You would have to find another way to implement it.

Or rather, that's a bug which should be filed and marked as blocker of this. (Until someone comes up with another solution.)

If Translate can display all these statistics separately, couldn't it display them in a same page? For instance, based on the data of pages like

https://www.mediawiki.org/w/index.php?title=Special%3ALanguageStats&x=D&language=de

A new page would show

Language Messages Untranslated Completion Outdated

German 5,137 3,166 38% 3%
Finnish 5,125 4,666 8% 1%

etc

Yes, see comment 4.

Kunal, are you still planning to work on this?

I wish I'm wrong, but can it be that this task is too complex for Google Code-in (although perhaps it could be split into digestive pieces) and too simple for a full internship?

@Kunalgrover05? :)

I couldn't figure out how to fix the issues in the patch https://gerrit.wikimedia.org/r/#/c/136626/, any suggestions?

The issue is that the aggregate group hierarchy is broken with this patch. I have a feeling we're very close. Maybe Niklas can have a look and indicate in which area something is being messed up?

This information is easily available via MessageGroupStats::forEverything It is just not exposed anywhere. Some logic is needed ala LanguageStats to deduplicate things.
