Title: Code-Completion sometimes can't deal with const in the right side.
Post by: photon3108 on August 30, 2009, 03:42:44 pm

If I declare a member function "int const & get_number( int const & index )" in header

file and define it in source code file, when I use them at another file, Code-Completion

can't rise well.


Actually, I don't know what makes this problem, is const in the right side or not.

Does someone has the same problems, too? How to solve it?

Thanks

Can't reproduce this problem.

C::B v.5716

I can't reproduce this problem, too. In fact, Code-Completion often doesn't wrok for

me, but I can't find the rules of these problems. I suspect "const" in the right side of

data type because I often see it when these problems happened.

for example,

void ClassA::function( ClassB const & b_1,
                              ClassB & b_2 )
{
    // The problem happened here.
    b_1.xxxxxx

    // Code-Completion works well here.
    b_2.xxxxxx
}

just wait for some time ,I will check into it after my computer back.
or you can have a try with cc-branch.

I can confirm this issue.It is relative to right const.

I got the reason why the right const don't work.
here is the reason:
for these codes,

Code

ClassB const & b_1, 

when the parser meet const ,it clear the m_Str;
see codes in void ParserThread::DoParse() in parserthread.cpp

Code

else if (token==ParserConsts::kw_const)
        {
            m_Str.Clear();
        }

as we known, m_Str stored the variable type,and if const is in
the right position and the parser clear the m_Str,the varible type will become
nothing ,that's why cc don't work.
I think the parser should do nothing when it meet const.
here is the patch.

Hi, You just comment out the related code, so the parser will skip all the "const".
Can we find a more convenient way?
I personally think skipping "const" is not a good manner.
