how to enable code completion feature for standart c++ library?
Not implemented yet, sorry. It will take some time, you can expect parsing of external headers in the second half of year. (The problem is that we have to find quick and dirty way how to deal with plentiful macros in standard C++ library - our parser does not preprocess files for performance reasons).
pardon me, but why to worry about c++ stdlibs?? It looks like upp handle of sort of things. just make prasing possible for any includable object as it is possible without any big chalenges. those, wich won't parse, parse not(maybee drop note like "unable to parse" if Assist++) . Just something, if it can parse, use it... or I am missing something(again )?
