I want to find some (maybe all) submissions in codeforces status history. And I want to filter the submission by languages. For example, only submission in Haskell is listed. How can I do that? Please share you ideas. Thank you.

Here's some solutions I found right now.

• In Gym, enter one contest, go to the status, hope some coders solved the problem in that specific languages. Search the submission by languages on the right window. Slow, Inefficient, I'm feeling lucky.

• Chrome plugin: Codeforces Enhancer. Show languages of a contest in the standing by different colors. Click to show the target languages. Not efficient enough, I'm feeling lucky.

• To be added...
