Hello, I’m writing my first clang-tidy check. Basically I’m working on a project where I’m forced to use systems hungarian notation. I was trying to get the applicable typedef from a vardecl (e.g. uin32_t)
I’ve started off with a simple matcher:
void AfrhungarianvariablesCheck::registerMatchers(MatchFinder *Finder)
{
Finder->addMatcher(varDecl().bind(“var”), this);
}
And I’ve been poking around what it finds with things like:
auto MatchedKind = MatchedDecl->getKind();
auto MatchedType = MatchedDecl->getType();
auto MatchedTypeRef = *MatchedType;
auto MatchedTypePtr = MatchedType.getTypePtr();
MatchedDecl->dump();
It’d be nice to have something like:
switch (type_of_var){
case int8_t:
prefix = “c”;
break;
case int16_t:
prefix = “s”;
break;
etc.
}
I’m mostly from an embedded C background, so a lot of the various tools to work with clang are a bit new to me (gdb, Clang AST, C++, etc). but I think a lot of this will be very useful to me in the future.
Also, I found a sort of getting started talk for clang-tidy in the videos from code:dive (https://www.youtube.com/watch?v=-QsiqIU8z7E), but the camera was never pointed at the screen. Is there anything similar with better camera work?
