Is it possible to improve the completion API?

[ema2159]

I've been improving the company-box package adding support for several company backends such as company-tern or company-anaconda. I also started working with company-irony but I found that I had to do kinda weird workarounds to find out the kind of completion candidate (i.e. if it is a class, a function, a struct, a variable etc). Other modes that provide completion just as anaconda-mode provide a nice API with information that tells you exactly the kind of the candidate (keyword, function, instance, class etc...). Am I missing something? Is there a way to extract that kind of information from company-irony candidates?

I guess it's just a matter of exposing clang_getCompletionParent():

• https://clang.llvm.org/doxygen/group__CINDEX__CODE__COMPLET.html#ga8afa885ca6547c96baa1369179b3b236

Which I think returns this list of possibilities:

• https://clang.llvm.org/doxygen/group__CINDEX__CODE__COMPLET.html#ga547e210f2ea6fc1fb4263b0d4d7e8102

You could try to add this information as a new member of the completion candidates:

• https://github.com/Sarcasm/irony-mode/blob/c3ae899b61124a747ebafc705086345e460ac08e/irony-completion.el#L262-L280

This is just what I need. I'll try to explore it and then I'll open a PR.
