I talked to corrados via mail and thought of automating some more steps in GitHub.

Reviewing a PR can be automated to some extent via a linter which enforces code style.

Unfortunately, I couldn't find a style guide (+ linter) which would fit to the Jamulus style, especially considering the two spaces between arguments in e.g. function calls/if statements:

if ( a ) seems to be uncommon.

Does anybody know a linter which supports custom styles and a GitHub action?
