I'm sry for the late reply. I sent an invitation to the org. Please feel free to move the repo to the org.

@shirobrak, thanks for your work on this project/action! I was trying to setup code suggestions for PHPCS and the following is the only way I got them working:

php ./vendor/bin/phpcs --report=diff -- $(git diff --name-only --diff-filter=ACMR origin/master | grep \\.php | xargs) | sed -r 's/[[:cntrl:]]\[[0-9]{1,3}m//g' | sed -E 's/--- (. )$/\0\n \1/g; /\ \ \ PHP_CodeSniffer$/d' | reviewdog -f=diff -f.diff.strip=0 -name=phpcs -reporter=github-pr-review -filter-mode=nofilter -fail-on-error

The first sed command removes some special characters which seem to be added when getting a diff report. The second one replaces the PHP_CodeSniffer filename with the actual file name so reviewdog is able to pick it up and add the suggestions to the right line/file.

Did you also have a look into how this can be done? Maybe there's a simpler way to achieve it? 🤔 This only reports the diff without the actual code violation. I assume for this an rdjson converter has to be written.
