Entries should end with a period (not the title, though). Also, if you
haven't signed FSF papers yet, you should append "TINYCHANGE" on a line
on its own.

This should be (delq nil all-links).

I don't see the interest of this change nor how it is related to
allowing ido usage to insert links. Can

  (append
    (mapcar (lambda (x) (list (concat x ":"))) all-prefixes)
            (mapcar 'car org-stored-links)
            (mapcar 'cadr org-stored-links))

contain nil values?

If so, adding a (delq nil (append ...)) should be enough. This should be
a separate patch anyway.

Ok. There are a couple of places where this could be used
(`org-file-complete-link' for example). You should describe ARGS in the
docstring, though (writing, at least, that they refer to arguments from
`read-file-name').

Also, I'm not sure about the name. `completing-read' became
`org-icompleting-read'. Shouldn't `read-file-name' become
`org-iread-file-name'?

Hi Nicolas, thanks for taking the time to go through the code.  I will resubmit the patch in a separate mail (I didn't know whether I could respond to your suggestions and submit a new patch in the same mail).

I have signed the FSF papers and they have been processed.

The problem is actualy the list bit, which causes a bug when using ido (but not when using normal completion).

Having gone through it again, I don't think the append can contain nil values, so I removed that bit.

> Shouldn't `read-file-name' become
> `org-iread-file-name'? 

Agreed and changed.

I don't think the patch can be split into two - the bug from list is only a bug if ido is used.

Here's some test code it case it helps:

Re: [PATCH] org-insert-link: allow ido usage when inserting links

[Samuel Wales]

Slighly different from this, I wonder if anybody has anything similar:

I have blog entries with a :Live-URL: property.  What I'd like is to
use ido to complete on the header that contains that property, and
create a link with the value of that property as the URL and the
header offered as default for the description.

Maybe this is too different?

Not too different.  Expanding the org-insert-link types to include headers was on my todo list (somewhere).  I think much of the functionality you need is already in the org-refile process.  In particular, the help for org-refile-targets says:

#+begin_quote
  A specification of how to find candidate refile targets.  This may be
  any of:
  - a cons cell (:tag . "TAG") to identify refile targets by a tag.
    This tag has to be present in all target headlines, inheritance will
    not be considered.
 #+end_quote
  
Rerouting the org refile technology to the link tech may be a one liner, or may be hard.  Others will have a better sense of the scope.

[tony day]

This time with patch inlined.

I had a look through and couldn't see an obvious reason why you can't use ido with org-insert-link, so here's a patch to enable it.

I haven't looked at using ido for editing links yet, but I figure org-capture would be a good pattern to do this.  The other thought here is to add an 'org:' link type so you can fire up ido just like org-capture (not sure what non-ido org-capture looks like).

This is my first patch, so please let me know if I'm not doing things right.

Hi, Tony,

thanks for submitting the patch,


however I suspect it is longer than 20 lines. 
Therefore it could be applied only if you've 
assigned the copyright to the FSF. For more infos please refer to:

http://orgmode.org/worg/org-contribute.html

Would it be possible for you?

Thanks,

Giovanni

I'm now marking this patch as not applicable in the patchwork,
and I've archived it.  Please resend it when the FSF papers are
in order.  

Also double-check the formatting of the ChangeLog entry: use 
the active voice, start sentences with an uppercase letter, end 
it with a "." and use two spaces after each... then you'll have
the perfect patch :)

Thanks!
