I'd like to find out which of the clang-tidy checks are possible to run with the -fix option, i.e. automatically generate fixed code. I know all the modernize-* checks can do this and some other checks can too (like google-readability-casting) but nowhere did I find a complete list. Is there a list somewhere? Or a method to find out other than reading the source of each and every check?
EDIT: Since clang-tidy 10 the fix option is included in the list of checks in the documentation.
The rest of my answer is still valid for versions 9 and lower.
grep --include=\*.cpp -rc './' -e "FixItHint"|grep -v ':0$' > FixItChecks.txt
I ran this grep command in the clang-tidy source directory. It counts the number of occurences of "FixItHint" string in all .cpp files and filters out files with zero occurences.
clang::FixItHint is a class that (according to documentation):
Annotates a diagnostic with some code that should be inserted, removed, or replaced to fix the problem.
I admit the method to obtain the list is somewhat crude however I did check multiple files and the results seem to be correct.
The cleaned-up and sorted list of checks with fixes:
