Make check mode output the file paths which are not formatted

[ldub]

Currently when I run ormolu -m 'check' ..., if two files aren't formatted, the tool will output:

Checking 804 files with ormolu...
ExitFailure 100
ExitFailure 100
make: *** [Makefile:194: check-format] Error 102

Here's my make rule, for reference:

check-format:
	IFS=$$'\n' sourceFiles=("$$(find src test -type f -name "*.hs")"); \
	ormolu -m 'check' $${sourceFiles[*]}

It would be useful if the check mode printed the paths of the files which failed to check, and not just ExitFailure 100.

Oh nice I didn't know that -m 'check' exists. Is there an overview of all modes somewhere in the documentation?

Try ormolu --help.
