[cfe-dev] How to implement "--fix" for a checker in Static Analyzer?

[Pradnya Laxman Khalate]

Hi,


I am a newbie in LLVM/Clang world. I started looking into Clang a month back for a class project.


I am using Clang from Windows and was able to build it with MSVS 2013. I was also able to add custom checkers to the Static Analyzers.


As per my understanding, the Static Analyzer can be invoked in 3 ways from the command line -

  1.  clang -cc1 -analyze -analyzer-checker=xxxx
  2.  scan-build utility
  3.  clang-check tool

I want to implement code fixer for my custom checker which would be invoked only if option "-fix" is present at input.


I was able to figure out the interfaces to implement for the code replacements. But, I couldn't understand how to implement it in my custom_checker.cpp.


I want to use scan-build because it generates intuitive HTML reports. But, scan-build doesn't accept the option "--fix", does it?


Is the best way to do this is using libTooling?


Any suggestions / guidance is appreciated.


Thanks,

Pradnya
