In VSCode how do I find all the Global variables in a function

[jshimkus]

I'm writing Lisp with VSCode and I need to find all the "Global" variables in a function so I can begin "Localizing" them.

This was pretty easy to do in VisualLisp, but how do I find the "Global" variables in VSCode?

I don't use VSCODE for lisp programming so I don't know if there is a IDE function that would extract all function variables for code written in autolisp/visuallisp. Logic is that all variables that are not added to localizing section of function definition are global. Some variables are intentionally created as global so localizing them may crash the code. Instead of relying on IDE functionality, read your code and localize variables defined inside function definition.

Variable can be set in different ways so I don' know if editor is capable to trace all function definitions.

(setq a 1 b 2)
(mapcar 'set '(a b) '( 1 2)) 
(set 'a 1) (set 'b 2)
(set (read name) 1)

Thanks, manually reading and localizing the variables is what I have been doing.

I was hoping that there was a trick, an extension or a json setting that would help point out the globals.

As long as there is an atoms-family function and VLisp functions...

Before your function call, (setq before (atoms-family 1))

After your function is called, (setq after (atoms-family 1))

Then, (setq global (vl-remove-if '(lambda (x)(vl-position x before)) after))

If you don't want the symbols as strings, leave out the 1.

Thanks John, that will work for now.
