The Atom editor plugin language-jenkins highlights the syntax for Jenkinsfile.
However, my Jenkinsfiles are not always named Jenkinsfile, but usually have extension: Jenkinsfile-x86, Jenkinsfile-arm, Jenkinsfile-test, etc.
How would I need to modify the Atom plugin source code in order to support any file name starting with Jenkinsfile*?
This poor man's solution works, but...:
'fileTypes': [
'Jenkinsfile',
'Jenkinsfile-x86',
'Jenkinsfile-arm',
'Jenkinsfile-test'
]
