This tool parses out your classes and their methods from header and CPP files. It turns out parsing out classes and methods in your C++ projects is actually very easy (if you don't need it to be life or death accurate). I'm not sure this is particularly useful; I had a specific use for this, and I just found it kind of interesting how easy it was. I'm sorry the formatting is wrong here, but CodeProject ate my whole article twice now, so I'm sorry!
Within our loop of headers and the lines in those headers, we simply check for the following; all other lines will be added and parsed later:
if (lines[lineCount].Contains(@"//"))
{
continue;
}
if (lines[lineCount].Contains(@"friend"))
{
continue;
}
if (lines[lineCount].Replace(" ", "").Contains(@"template<class"))
{
continue;
}
if (lines[lineCount].Contains(@"_T("))
{
continue;
}
To parse the CPP, your loop will exclude only these keywords (I know I'm missing tons of cases here, but surprisingly it seems to work not too shabby :)):
if (lines[lineCount].Contains(@";"))
{
continue;
}
if (lines[lineCount].Contains(@"//"))
{
continue;
}
if (lines[lineCount].Contains(@"_T("))
{
continue;
}
if (lines[lineCount].Contains(@"if"))
{
continue;
}
if (lines[lineCount].Contains(@"="))
{
continue;
}
if (lines[lineCount].Contains(@"."))
{
continue;
}
if (lines[lineCount].Contains(@"."))
{
continue;
}
if (lines[lineCount].Contains(@"return"))
{
continue;
}
Obviously, there is a lot missing to make this useful for most people, but it is kind of interesting and perhaps could be used as a learning tool. Also, you could structure this code much cleaner by searching for exclusion keywords and having them in a list, that might be a good exercise for someone.
It also should check for duplicates to handle overloaded methods and many more such issues.
Cheers..
