Linter

Linter for Monkey C code to find both stylistic and other issues in the code. When possible the linter supports automatically fixing the issues by using the --fix flag.

Note

The fixer doesn’t format the code to normalize after changes so the user is expected to run the monkey-c-formatter after applying fixes.
