i know this is a *very* late response but life/work has dragged me in last few months and only now i have time to take a look at org-dp :)

if you remember i have near to null coding skills but i am trying to make sense of stuff looking at the github site and the org-dp.el examples

i understand (or at least i think i do) that org-dp is very complex and covers not just wrapping in source code lines/areas but what i basically need is to assign hotkeys to specific wrapping. mainly these:

1. a hotkey to quick wrap in language X a line
2. a hotkey to quick wrap in language X y lines
3. a hotkey to quick wrap in language X a selection

any tips and how to start/create these keybinds? is there a more comprehensive documentation on org-dp somewhere else i may have overlooked?

thx alot!

good, thanks.

As a hint, here the global keybindings I defined in my init.el (my
default use-case is to simply wrap in a plain emacs-lisp src-block).

You can define all kinds of functions that don't prompt the user anymore
by giving a list like

 '(elem-type contents replace affiliated args)

as second arg to `org-dp-wrap-in-block', and in that list you can
specify any kind of customized block.

#+BEGIN_SRC emacs-lisp
(when (require 'org-dp-lib nil t)

  (defun tj/wrap-in-elisp-block ()
    (org-dp-wrap-in-block
     nil '(src-block nil nil nil (:language "emacs-lisp"))))

  (global-set-key (kbd "C-c w w") 'org-dp-wrap-in-block)

  (global-set-key (kbd "C-c w l")
                  (lambda ()
                    (interactive)
                    (let ((current-prefix-arg '(4)))
                      (call-interactively
                       'org-dp-wrap-in-block))))

  (global-set-key (kbd "C-c w e")
                  (lambda ()
                    (interactive)
                    (beginning-of-line)
                    (tj/wrap-in-elisp-block)))

  (global-set-key (kbd "C-c w a")
                  (lambda ()
                    (interactive)
                    (backward-sexp)
                    (beginning-of-line)
                    (tj/wrap-in-elisp-block))) )
#+END_SRC
