feature request: convert links about markdown-mode HOT 13 OPEN

This is an existing feature: Place the point anywhere in the inline link and press C-c C-a r (as if you were inserting a reference link) and the link will be converted to a reference style link.

from markdown-mode.

btw, i don't know what markdown you are using, but with pandoc you can just do [foo] instead of [foo][].

from markdown-mode.

damn, i was offline and ended up rewriting this thing twice... here's what i ended up with:

(defun anarcat/markdown-convert-link ()
  "convert a [text](link) link format into [text][] ... [text]:
link

allowing search-backwards (say with a prefix) could also be
interesting.

This is discussed in
https://github.com/jrblevin/markdown-mode/issues/94 and should be
eventually merged upstream once it is acceptable elisp.

  (let ((text (match-string 1))
        (link (match-string 3)))
    ;; remove the link and replace with brakets
    ;; link is the "2" below, and replace only that
    (replace-match "[]" nil nil nil 2)
    ;; go at the end of the paragraph and add stuff there
    (save-excursion
      (search-forward "\n\n")
      ;; insert the link reference
      (insert (format " [%s]: %s\n\n" text link))
      ;; XXX: we insert two newlines to avoid breaking the paragraph
      ;; break, but that makes too many spaces if we insert many links
      ;; like this. not sure how to fix this.
      )
    )
  )

also, C-c C-a r does not convert a link here: it just adds a new one. i am using markdown-mode.el 2.0 from Debian jessie, looking at the current code it seems this is a new feature from 2.1... grml.

oh well, i gues it's time to load a new version from ELPA. :)

@vyp as for the markdown dialect, i'm writing for ikiwiki, using the default markdown processor (which is not pandoc).

from markdown-mode.

markdown-mode is still at version 2.0 in marmalade, it seems. MELPA has a snapshot from 2016, which works, so I guess i just wasted time re-learning elisp programming. which was actually nice. :)

thanks!

ah - one thing my function does a little better is that it puts the link at the end of the paragraph instead of at the end of file, which I like because it makes the plain text more readable: you don't have to jump to the end of file to follow links by hand.

You can customize the location for inserting reference definitions by setting markdown-reference-location.

cool, that's what i was looking for, thanks!

Is it me or did this feature disappear?

If I have a document that only has [foo](link) and I move the point to "link" then type C-c C-a r, it just prompts me for the same link info again but doesn't convert the link...

Ideas?

from markdown-mode.

I combined the three old functions (for inline, reference, plain URL links) into one with the new C-c C-l command. The old commands are now aliases for it. If you remove the URL (kill it for using later), then give a reference label it will convert for you. If the ref isn't defined, one will be added and you'll be prompted for the URL (which you can then yank).

The idea is that it uses whatever information you give it to determine the link type. There are examples of other possible conversions in the documentation.

from markdown-mode.

oh i see. sorry for not catching up on the docs and all the noise. ;) short too, i like it. i'll try to train my muscle memory back in polace - thanks!

from markdown-mode.

It's no problem. My sense at the time was that C-c C-l would be more intuitive, but I'm considering bringing back dedicated conversion commands, as they do avoid shuffling URLs/text around.

If you remove the URL (kill it for using later), then give a reference label it will convert for you. If the ref isn't defined, one will be added and you'll be prompted for the URL (which you can then yank).

I understand this ticket is getting really old by now, but I keep on thinking about it every time I switch links between inline and ref. That process actually takes a long time. The actual keystrokes are:

• C-c
• C-l
• alt-backspace (orc-s-left c-w)
• RET
• RET
• c-y
• RET

phew! i often end up doing a macro instead, but it's not very reliable: if a ref already exist, it kind of explodes midway...

it would still be nice to have a wrapper around this, possibly by setting a prefix argument?

similar: #565

i reworked my code a bit and ended up with something like this:

(defun anarcat/markdown-convert-link ()
  "Convert markdown inline links to references.

would you be open a merge request to add that to markdown-mode?
