Yes, configure it either in the wizard or in the .mwe2 file as a comma-separated list.

What is the approach for including a comma-separated list in the .mwe2 file to accept two extensions, specifically two case-sensitive versions (e.g., .mydsl and .MYDSL)?

I've tried a few different approaches but can't get the 2nd extension to work. In fact, when I change the .mwe2 file to include only the 2nd extension (MYDSL) and not the 1st extension (mydsl), re-run the .mwe2 workflow, and launch the UI, it appears to make no change.

e.g., changing from

var file.extensions = "mydsl"

to

var file.extensions = "MYDSL"

and re-running the MWE2 workflow will still only open files of type .mydsl, and throw an IllegalStateException for MYDSL.

Any thoughts on how to get the UI to recognize a 2nd case-sensitive extension in an existing project?

Thanks.

Hi,

note that you will have to merge the plugin.xml and plugin.xml_gen manually after regenerating.

Use F3 on the "setter" for the file extension in order to see, how it is handled in the actual code. If a comma separated list is used,
var file.extensions="mydsl,MYDSL" should probably work.
