Question: is the firstLineMatch key active in tmLanguage files? I noticed that, when loading a LaTeX beamer file, with a \documentclass{beamer} command as the first line, the syntax is not switched to LaTeX Beamer, but plain LaTeX. Thanks!

It is active, but it currently doesn’t take precedence over the file extension. You should be able to see it in action by pasting the text into a new file, which will also trigger the firstLineMatch based detection.

I quick question: Are the file extensions still taking precedence over firstLineMatch? I did some test with Obj-C and Matlab files which share the extension ‘*.m’ and it does look like.

If yes, do you have any plans to change that?

Cheers

I too am having problems with my Matlab files being considered objective C. Incidentally, I tried deleting the objective C syntax directory and now by default Matlab is not highlighted at all.

Hi if anyone has come across this problem and doesn’t use ObjC

The fix to this is to add the file extension Matlab.tmLanguage

and remove that from the Objc.tmLanguage file
