commas in URLs?

commas in URLs?

[Adam Spiers]

It looks like there's a regular expression somewhere which might need
tweaking, e.g. when pasting the following into an org-mode buffer:

  http://reviews.cnet.co.uk/dvdpvr/0,39030416,49283669,00.htm

only the bit up to the first comma gets hyperlinked.  That's with
5.17a at least - ashamed to say I haven't had a chance to upgrade yet
:-)

Thanks!

Yes, plain links are terminated by (among other) comma.

Please enclose such links into <...> or [[...]]]

Ah, OK thanks!  Just curious - what's the reasoning behind excluding
commas?

So that you can write

Popular search engines are http://google.com, http://yahoo.com, and http://ask.com 
  .

Nice - agreed that that's a more common use case than the one
involving commas in URLs.  Thanks again!

So URLs should just exclude commas that are followed by a whitespace or
a line break, not all commas - right?  Anyway, I guess 99% of URLs are
enclosed in brackets, so it might not be worth being fussy on this...

Hmm, good point!

> Anyway, I guess 99% of URLs are enclosed in brackets,

Not true here, by a long shot!

$ egrep -c 'https?://' */TODO.org
work/TODO.org:78
personal/TODO.org:180
$ egrep -c '[<[]https?://' */TODO.org
work/TODO.org:8
personal/TODO.org:50

So that's 58 out of 258 enclosed in brackets, which is 22.5%.

Yes, but this is harder to do with a regexp.  I wish Emacs had look- 
ahead assertions like perl.

Maybe we can add something to the manual to avoid confusion.

Can someone propose this feature to emacs-devel?

This is the main bother I have with emacs, I wish RMS would allow it to
be linked with PCRE or similar. It would rid us of most of those ugly
backslashes too.

Just to to add one vote for including commas in the urls by default
(at least in some cases); I often copy long links directly from the
browser and have this problem quite often.

What about saying that a url cannot end with a comma, but can contain
commas?  Something like [a-z,]*[a-z] (this is a big big simplication!).

Excellent suggestion, yes, this works.  Sometimes there are good ways to
work around, and in this case this works perfectly.  Thanks!
