Using RubyMine 2019.3 on MacOS
I have noticed that rubymine now provides some rudimentary syntax highlighting and formatting for files named 'Jenkinsfile'. While it doesn't provide full GDSL style autocomplete etc., it is really useful.
I have a few other Jenkins pipeline files that I want to extend these capabilities to: 'Jenkinsfile.production' 'Jenkinsfile.foo' etc. However, RubyMine treats these as simple txt files. I can't find anything that controls the 'Jenkins Pipeline' file association. "Preferences > Editor > File Types" doesn't include any file type mapping for 'Jenkinsfile'.
I confirmed this behavior with an install of RubyMine 2019.3 with all downloaded plugins disabled. Furthermore, I was able to verify that this behavior was seen as far back as 2019.2.3 but was not present in 2019.1.1. I haven't seen any mention of it in RubyMine release notes either. I have no idea when it was introduced.
Am i going insane here? Does anyone know how i can extend this highlighting support to a more expansive set of Jenkins pipeline files?
