Displays defconst string in help buffer

Displays defconst string in help buffer

[Heime]

I have a defconst declaration called "attend".  Would like to have a function that displays the "attend" string 
in the help buffer as is done by "describe-function".  What can I do?

Use the source, Luke!

C-h f describe-function RET

If you see a button there to the source, hit it. 

It's in help-fns.el lines 251-284.

If you don't see a link, see if you can get that. Do you build
Emacs from source? If not ... see if you can get that!
Here are a bunch of useful commands:

Yes, I build from source.  

I have done the following solution

  (with-help-window (help-buffer)
    (insert attend-message))

Do you also configure with --with-native-compilation ?

This will speed up things a lot.

On a Debian-type system, install libgccjit-10-dev, that's
where the capability resides that can translate Elisp into
machine code.

It says JIT but it doesn't seem to happen that way, rather it
compiles natively and caches every time you start Emacs and it
loads something that isn't already cached (say a byte-compiled
Elisp file).

You still want to byte-compile tho for educational reasons not
the least ...

I did not.  Just followed INSTALL.REPO "Building and Installing Emacs from the Repository".
