When I put the following code at the start of
my .emacs file it executes without errors as
it should.

However when I evaluate (smegulator) it brings
up the following message, without a black triangle

elisp--eval-last-sexp: Symbol’s value as variable is void: void-variable-smeg

When I execute C-u C-M-x on (defun smegulator () void-variable-smeg)
it brings up the following messages.

edebug-after: Symbol’s value as variable is void: void-variable-smeg

elisp--eval-last-sexp: Symbol’s value as variable is void: void-variable-smeg
with a black triangle indicating we are in edebug mode.

How do I get the black triangle online in other files for debugging my code?

i.e. how do you get Emacs to do a C-u C-M-x on every defun without doing
it manually C-u C-M-x for every function one at a time?

According to the manual:

If ‘edebug-all-defs’ is non-‘nil’, then the commands ‘eval-region’,
‘eval-current-buffer’, and ‘eval-buffer’ also instrument any definitions
they evaluate. Similarly, ‘edebug-all-forms’ controls whether
‘eval-region’ should instrument _any_ form, even non-defining forms.
This doesn’t apply to loading or evaluations in the minibuffer. The
command ‘M-x edebug-all-forms’ toggles this option.

Another command, ‘M-x edebug-eval-top-level-form’, is available to
instrument any top-level form regardless of the values of
‘edebug-all-defs’ and ‘edebug-all-forms’. ‘edebug-defun’ is an alias
for ‘edebug-eval-top-level-form’.

I think this answers your questions.
