sexp in org remember templates

sexp in org remember templates

[Richard Riley]

Not being much of an elisp programmer and just returning to try and
integrate with org-learn a little :-

This 

	      ("vocab"?v "* Learn TODO %(format '%s' rgr/orig-word)
	      :VOCAB:\n:PROPERTIES:\n:orig:\t%(format '%s'
	      rgr/orig-word)\n:trans:\t%(format '%s'
	      rgr/trans-word)\n:END:%!" nil bottom nil)

fails me by outputting:

,----
| * Learn TODO [Error: (wrong-type-argument stringp %s)]		      :VOCAB:
| :PROPERTIES:
| :orig:	%![Error: (wrong-type-argument stringp %s)]
| :trans:	%![Error: (wrong-type-argument stringp %s)]
| :END:%!
`----

both rgr/orig-word and rgr/trans-word are set as strings.

Q1 : can I use an elisp var directly as opposed to simulating a func like
above?
Q2 : What is wrong with the above? Whats wrong with that format of a
sexp?
Q3 : how can I specify in the template to auto schedule a TODO for "n"
days in advance?

Just to follow up to my own post I now see a ginle function call will
work e.g

 	      ("vocab"?v "* Learn TODO %(rgr/orig-word)
 	      :VOCAB:\n:PROPERTIES:\n:orig:\t%(rgr/orig-word)\n:trans:\t%(rgr/trans-word)\n:END:%!"
 	      nil bottom nil)

Possibly me not knowing enough elisp but possibly also could support my
initial attempt? Thanks for any explanation.

At the very least, you need to avoid single quotes for quoting strings -
a single quote has a very special meaning to lisp in general: it inhibits
evaluation of the following sexp.

Try something like this instead:

("vocab"?v "* Learn TODO %(format \"%s\" rgr/orig-word)
 	      :VOCAB:\n:PROPERTIES:\n:orig:\t%(format \"%s\"
 	      rgr/orig-word)\n:trans:\t%(format \"%s\"
 	      rgr/trans-word)\n:END:%!" nil bottom nil)

However, no guarantees: when (or even whether) the format calls will be executed
(let alone whether they'll produce the correct result) depends on the
code that handles this construct. There have been a couple of questions
on the mailing list about such evaluations in the context of
org-remember-templates, and IIRC, Carsten had added an evaluation
mechanism there - see e.g. the thread at

   http://thread.gmane.org/gmane.emacs.orgmode/14521

and another thread referenced therein for some details. But I don't know
if this will do what you need it to do.

HTH,
Nick

Thanks for the info. In the meantime I had just created two functions
with no parameters to return the values and this worked. 

Trying now to auto remember. I have some code like this:-

,----
| (defun rgr/context-babel()
|   (interactive)
|   (save-window-excursion(unwind-protect
| 			    (let* ((default (region-or-word-at-point)))
| 			      (setq default (read-string (format "Translate \"%s\" :" default) nil nil default))
| 			      (when (length default) (setq
|   rgr/trans-word (babel default nil t))(setq rgr/orig-word
|   default)(org-remember nil ?v)(message "%s" rgr/trans-word))))))
`----

Thanks. I had already create two funcs to call so my template is now:-

,----
| 	      ("vocab"?v "* TODO Learn %(rgr/orig-word)
| 	      :VOCAB:\n:PROPERTIES:\n:orig:\t%(rgr/orig-word)\n:trans:\t%(rgr/trans-word)\n:END:%!"
| 	      nil bottom nil)
`----

and the translate code I call does this:

,----
| ;;;###autoload
| (defun rgr/context-babel()
|   (interactive)
|   (save-window-excursion(unwind-protect
| 			    (let* ((default (region-or-word-at-point)))
| 			      (setq default (read-string (format "Translate \"%s\" :" default) nil nil default))
| 			      (when (length default) (setq rgr/trans-word (babel default nil t))(setq rgr/orig-word default)(org-remember nil ?v)(message "%s" rgr/trans-word))))))
`----

and now I have my translate hot key auto creating VOCAB TODOs. The only
thing I need to know now is how to auto schedule them.
