What happens when formatting fails because of syntax error?

[etiennebacher]

Suppose I have a file with a syntax error, e.g. 1 +. Currently air format . errors with

ERROR Failed to format foo.R: Failed to parse due to syntax errors.

It's not clear from this message if other files were still formatted or if this error stopped the formatting for the rest of the folder as well.

Basically:

• if the error stopped formatting for other files, is it possible to prevent this behavior to only stop formatting for the file with the syntax error?
• if the error didn't stop formatting for other files, can it be mentioned in the error messages? For example:

ERROR Failed to format foo.R: Failed to parse due to syntax errors.
ERROR Failed to format foo-bar.R: Failed to parse due to syntax errors.
ERROR Failed to format other-file.R: Failed to parse due to syntax errors.

Remaining files were correctly formatted.

Other files are still formatted. Maybe it's worth saying Successfully formatted {n} files. unconditionally? And n would be total_files - errors. I think I'd like for us to try not to be too noisy though, so idk if that's really worth it.

Yes this could be enough, e.g.:

Formatted n files.

and

Formatted n files. Errors for x files:
format foo.R: Failed to parse due to syntax errors.
