Visual Studio Code – Run 2 transforms on 1 snippet in VSCode

I want VSCode to generate my classname based on my filename:

Filename: test-class-file.php should become: Test_Class_File
I found the following examples:

  1. "${TM_FILENAME_BASE/[-]/_/g}" Becomes: test_class_file
  2. "${TM_FILENAME_BASE/(.*)/${1:/pascalcase}/}" Becomes: TestClassFile

The official docs Do not mention chaining or anything like that.
There also doesn’t appear to be a way to store something in a temp variable.
How can I combine these 2 into one transform/regex action?

    You can use

    "${TM_FILENAME_BASE/([^-])([^-]*)|(-)/${1:/upcase}${2:/downcase}${3:+_}/g}"

    This will work like this:

    • ([^-])([^-]*) – captures the first non-hyphen char into Group 1 and the rest of non-hyphen chars into Group 2
    • (-) – captures any -s into Group 3.

    When Group 1 matches, it is turned into uppercase, Group 2 contents is turned to lower, and every - is replaced with _.

    This is much simpler:

      "${TM_FILENAME_BASE/(-)|([^-]+)/${1:+_}${2:/capitalize}/g}"

    Just use the captitalize transform on the non-hyphen groups.
