How to create custom commands in VSCode?

Question

In Emacs, I can create functions in Lisp language and place them in .emacs file. Those function will become commands that can be called from the editor or bound

Answer 1

There's Power Tools by e.GO:digital. It has support for custom commands and event triggers (ie. on file changed), among other things.

Answer 2

A few marketplace extensions may be of interest:

• Script Commands by Marcel J. Kloubert
• multi-command by ryuta46

However in general, you'll need to write an extension to do anything complex.

There's also a VS Code issue tracking support for built-in macros
