Babel Forth

["Thomas S. Dye" <tsd@tsdye.online>]

Aloha all,

I'm drafting ob-doc-forth.org and haven't been able to get 
ob-forth.el to recognize a working GForth in Spacemacs.  I get 
"Symbol's function definition is void: forth-proc" when I evaluate 
a Forth source block.

In ob-forth.el there is this: (declare-function forth-proc 
"ext:gforth" ())

My hunch is that the ext: part of ext:gforth expects that 
forth-mode is setup to use the forth-mode distributed with GForth. 
Spacemacs appears to use forth-mode from Elpa, instead, and I find 
forth-mode.el in the elpa subdirectory of my Spacemacs.

I don't program in Forth and given my limited grasp of elisp, I 
don't look forward to debugging this just to draft some 
documentation, so I'd like to ask for help.

Have I diagnosed the problem correctly?

If so, could ob-forth.el be patched to enable all Emacs 
users--plain, Spacemacs, Doom, Prelude, Scimax, etc.--to evaluate 
Forth code blocks?  Or, should ob-doc-forth give instructions how 
to setup forth-mode to use the one distributed with GForth?

What is the best way forward here?

All the best,
Tom
