VSCode extensions: code-outline for Perl .cgi files

Question

I'm trying to use Visual Studio Code for Perl (on Debian 9). I have installed VSCode extensions:

• Code Outline (by Patryk Zawadzki);
• Perl (by Henrik Sjooh).

Extension code-outline works great for .pl files but doesn't for .cgi files (although both .pl and .cgi recognized as Perl files). I can't find any info for how to fix it. Maybe someone did the same already? How to make code-outline extension works for .cgi files too?

Answer 1

File extensions don't really matter.

In the bottom right of the Visual Studio Code window will be a menu where you can pick the language you are working on.

It won't default to Perl for files with a .cgi extension, but you can change that.
