Tags: code | So after getting about 9000 warnings building Lgi with the latest XCode 3.x I
decided that I would do something about it. A lot of the warnings consisted of
"casting from const char* to char* is deprecated" because I was passing a
string constant into a char* arg. So I fix one of those. Which causes 4 more.
And so I fix some more of those, and it snowballs... and snowballs... and then
there is an avalanche of API's getting 'const' all through them. Many days
latter I'm now back on top of the warnings. However now I've modified a
number of base classes with virtual functions that had char* arguments. Of
course the compiler doesn't warn you when your child class stops overriding
the parent function does it! So the big hunt for mis-matched function
definitions begins. No doubt I'll miss some and random stuff will just stop
working, because the base class got the call, not the child class. *sigh*
Update: So after finding most of the problems by bumping into them
accidentally I realized that I was going to missing something important
anyway. So I wrote a python script that calls ctags to extract a bunch of
symbol definitions, then it parses through all those and finds all the class
methods, and compares their arguments and return type with the parent
classes virtual function, and spits out an error if they differ. This was great, it
picked up a few methods I'd missed, and gave me confidence that I could
release the next build of Scribe without having broken functionality.
