# Undefinder
Undefinder is a small utility that searches C codebases for unused
preprocessor `#define`s.
Its biggest shortcoming is that it doesn't understand comments, so it
will treat commented out macros as defined, and it will treat textual
occurrences of macros in comments as uses.
## Usage
Requires [go](https://golang.org/).
go run undefinder.go --exclude-defines="dont-report.c" /my/c/codebase
The output can be parsed like C compiler errors/warnings.
