A small tool to check go source code for proper formatting according to gofmt, but rather than reformat the code it exits with exit code 0 if the code is properly formatted and 2 if it is not (and 1 if there was some other sort of error). This is useful in the case such as a CI build script if you want to easily check if code complies with gofmt standards.
Tested with go1.3 through go1.5, may work with other versions but not necessarily guaranteed.
Usage of ./go-retfmt:
-dir string
Directory to search (default ".")
-ignore string
Comma-separated directories to ignore (useful for vendored deps) (default "")
