Before this change it is not apparent from the help text that -s/--stdin takes a file name argument.

Given the error message shouldn't we check if args has a size of 1?

With this change the file name given to --stdin is now an argument to the option, so it doesn't go into args. I can add a comment clarifying this. Or change the message to "No other files can be given when --stdin is used"?

Or you can do both. :-)

Not sure about the wording of the error message, though.

In the end I couldn't come up with a message that better than the one we've got, so I only updated the comments.

Hi @jonas054, this has broken an Atom plugin that I use, linter-rubocop. It tries to use a command like the following, which used to work in v0.48.0, but now fails:
bin/rubocop --stdin --display-style-guide /path/to/file
Due to triggering the error:
-s/--stdin requires exactly one path.

Before I make an issue... I'm just wondering if this new stricter behaviour is intended, if it is I'll make the issue/PR in their repo instead.

@savef The new stricter behavior is sort of a byproduct of the better description from --help. But we should stick with it IMO. Ask linter-rubocop to call bin/rubocop --display-style-guide --stdin /path/to/file

Never mind, it looks like a newer version of the plugin happened to do a re-write (CS -> ES6) and proactively fixed my issue as part of that. 😄

I had decided the new RuboCop behaviour was probably the correct one anyway.

Edit: Thanks, @jonas054!

rubocop/rubocop#4226 indicates that `--stdin`
takes filename as an argument which was incorporated. Also, the tests
were enhanced that involved the bear to be run on files with the `.rb`
