Subject: Hooking document specific src blocks into default actions
Date: Mon, 26 Feb 2018 12:28:16 +0000 [thread overview]
Message-ID: <87tvu46ilb.fsf@linaro.org> (raw)
Hi,
I've been using these for a while but I recently wanted to add a
function at the head of the ctrl-c-ctrl-c processing:
(defvar my-org-default-action nil
"Default action for this document to run on `org-ctrl-c-ctrl-c'.
\\<org-mode-map>
This will run via `org-ctrl-c-ctrl-c-hook' and should return a
non-nil result if it processed something. As such it can override
default `org-mode' behaviour for \\[org-ctrl-c-ctrl-c]. If you
want something to run at the end then you need to use
`my-org-default-code-block'")
(make-variable-buffer-local 'my-org-default-action)
(defun my-org--do-action (func-or-string)
"Evaluate a code block or call a function `FUNC-OR-STRING' from org-file."
(let ((current-point (point)))
(cond
((stringp func-or-string)
(save-excursion
(org-babel-goto-named-src-block func-or-string)
(org-babel-when-in-src-block
(org-babel-eval-wipe-error-buffer)
(org-babel-execute-src-block current-prefix-arg nil
'((:called-from . current-point))))))
((functionp func-or-string)
(funcall func-or-string))
(t (error "What to do with: %s" func-or-string)))))
(defun my-org-run-default-action ()
"Execute default action for this org file."
(interactive)
(when my-org-default-action
(my-org--do-action my-org-default-action)))
(add-to-list 'org-ctrl-c-ctrl-c-hook
'my-org-run-default-action)
However I've run into a small problem that when I execute the source
block I end up with 't every time as we successfully executed the block
even if it didn't end up doing anything at the time.
Is there a better way to invoke source blocks from the current
org-document than this? One where the eventual result can be returned
into the calling lisp so org-ctrl-c-ctrl-c-hook can move on if we didn't
do anything?
