* How to programmatically use/edit data provided on capture

Hi all!

I got capture template with prompts to collect some properties:

#+BEGIN_SRC
* TODO %\1 / Some task description
    :PROPERTIES:
    :NAME: %^{NAME}
    :END:
#+END_SRC

My question is: How to get information on user input data to transform 
this data before capture finalize.

For example: I got variable NAME and would like to use function like 
(s-dashed-words string) from s.el to make sure that my NAME is valid and 
converted to dashed syntax.

Let's say that my input is: New random project

I would like to have:

#+begin_src
* TODO new-random-project / Some task description
    :PROPERTIES:
    :NAME: "New random project"
    :END:
#+end_src

While currently I got:

#+begin_src
* TODO New random project / Some task description
    :PROPERTIES:
    :NAME: "New random project"
    :END:
#+end_src

I have been trying:

#+BEGIN_SRC
* TODO %(custom-dashify-function %\1) / Some task description
    :PROPERTIES:
    :NAME: %^{NAME}
    :END:
#+END_SRC

or

#+BEGIN_SRC
* TODO %(custom-dashify-function %\\1) / Some task description
    :PROPERTIES:
    :NAME: %^{NAME}
    :END:
#+END_SRC

But apparently function is executed before %\1 is replaced by my data 
and it dodesn't work.
Could someone help me to write function that would get data I provided 
for property NAME, convert using s-dashed-words and return to template 
before finalize?

I too have wanted to do something like this, but I am not sure that it
is possible without hacking org-capture, because I don't think you can
hook into the template processing at an arbitrary point.

Is it really important that you transform the data *before* capture
finalize?  If not, I think you could do this *during* capture finalize
by replacing, say, a pre-determined string "PUT-NAME-HERE" with the value of 

(custom-dashify-function (org-entry-get (point) "NAME"))

You could do that from org-capture-prepare-finalize-hook, maybe.  Would
that work for you?  It has some limitations:
  - it's only easy to recover data that was entered as properties or tags, not
    arbitrary strings
  - you can't continue to edit the capture buffer after doing this
    processing, since the hook will only be called after you start
    finalization 
 
If you come up with a better solution, I'd like to hear about it!  I
have scratched my head about this several times before, but I've never
come up with a satisfactory solution.

Good luck!

Best,
Richard
