@rmaganacs I’ve really enjoyed using this extension. Question relevant to another project I’m working on below, trying to write an Emacs major mode for SenseTalk. The question is: When you developed the syntax portions of your VC extension, what were your primary references? Was it just the SenseTalk Reference? Any other documents or code you may have used? I’ve been looking at major modes for languages in the xTalk family, but I get the feeling I should really start from scratch. Thanks!
