Are you a hardcore elisp programmer? Add this to your ~/.spacemacs:

dotspacemacs-additional-packages '(
 (treemacs :location
             (recipe :fetcher file
                     :path "~/path/to/treemacs/src/elisp")
           :update nil))

Now you can hack on any emacs package in your live editor!

Notes Link to heading

You will need to manually delete the package from ~/.emacs.d/elpa/29.0/develop.
The path is supposed to point to the location of *.el files.
Heavy lifting is done by quelpa, read their docs!

Emacs Lisp interactive debugging

Mon, 10 May 2021 11:05:44 +0000

Navigate to your function.
Instrument it with C-u M-x eval-defun, or C-u , e f in Spacemacs.
Execute that function.

Debug with these shortcuts:

Key	Action
`s`	Next sexp.
`i`	Step in.
`o`	Step out.
`d`	Backtrace.
`Q`	Quit.

Once you’re done, re-evaluate all functions (without C-u), or simply restart.
