Hmmm, you mean try to find heuristically where e.g. in the ob-shell.el
file the org-babel-execute:sh function was defined?
The function body is this:
(lambda
(body params)
"Execute a block of sh commands with Babel."
(let
((shell-file-name "sh")
(org-babel-prompt-command
(or
(alist-get "sh" org-babel-shell-set-prompt-commands)
(alist-get t org-babel-shell-set-prompt-commands))))
(org-babel-execute:shell body params)))
and it has been created here:
(defun org-babel-shell-initialize ()
"Define execution functions associated to shell names.
This function has to be called whenever `org-babel-shell-names'
is modified outside the Customize interface."
(interactive)
(dolist (name org-babel-shell-names)
(eval `(defun ,(intern (concat "org-babel-execute:" name))
(body params)
,(format "Execute a block of %s commands with Babel." name)
(let ((shell-file-name ,name)
(org-babel-prompt-command
(or (alist-get ,name org-babel-shell-set-prompt-commands)
(alist-get t org-babel-shell-set-prompt-commands))))
(org-babel-execute:shell body params))))
(eval `(defalias ',(intern (concat "org-babel-variable-assignments:" name))
'org-babel-variable-assignments:shell
,(format "Return list of %s statements assigning to the block's \
variables."
name)))
(eval `(defvar ,(intern (concat "org-babel-default-header-args:" name)) '()))))
Do you think there is a way to find that place? AFAIU, all elements in
the function definition could be variables in the form that is evalled.
