Hello list,

If I insert a http:// link containing question marks, the verbatim link
being inserted in the org document has the question mark escaped.

For example the link

http://mpcjanssen.nl/fossil/simpletask/tktview?name=ee0504fc8c

is actually inserted as:

[[http://mpcjanssen.nl/fossil/simpletask/tktview?name%3Dee0504fc8c][bug]]

This works fine when clicking the link from emacs, but breaks when
exporting to html. Then it is exported as:

<a href="http://mpcjanssen.nl/fossil/simpletask/tktview?name%3Dee0504fc8c
">bug</a>

This will not work.

Is this an error in the html exporter or in org mode itself? I would expect
the link to be included verbatim in the .org file.

Regards,
Mark

Seems (setq org-url-hexify-p nil) will give me the required behavior.

This didn't work, so I investigated a bit further. Because the = sign is
included in org-link-escape-chars, the org-url-hexify-p value will not make
anu difference.

So the problem is still that equals signs are hexified in org-links.
Reading =org.el= and seeing the =org-link-escape-chars= constant this seems
to be expected behavior.

So I think the issue is that the html exporter doesn't unhexify the equals
sign in the link. As a result the link in the html doesn't work.

e.g.

The link:

http://test/test?name=me

Is translated to:

http://test/test?name%3Dme

In the org file

And that link is also included in the HTML where I would have expected the
equals sign again.

I can't reproduce this with latest stable or unstable Org version.

What version of Org and Emacs are you using?

M-x org-version RET
M-x emacs-version RET

Thanks,

I shouldn't have posted this to the mailing list at the time I did :(.
Apologies for any confusion I have caused.
 The problem is with escaping of an equals sign not the question mark.

I have attached a demo org and a resulting html file. Note that in the html
file, the url is http://test/test?name%3Dme which is wrong. It should be
http://test/test?name=me

Running C-c C-ehh on that org file gives the attached html. I have started
emacs as:

emacs.exe -Q -l minimal.el test.org

;;minimal.el
(require 'package)
(package-initialize)
(require 'org)

Hi Mark,

it has been fixed in the master branch by Rick, I've cherry-picked the
change in the maint branch so that it will be part of the next minor
release.

Thanks,

Hi Bastien

From the commit of Rick Frankel for org-html-link (reformatted):

#+BEGIN_SRC emacs-lisp
  (org-link-escape
   (org-link-unescape (concat type ":" raw-path))
   org-link-escape-chars-browser)
#+END_SRC

I would like to discourage the use of the constant
org-link-escape-chars-browser in favor of the function
org-link-escape-browser that should use, and finally can be replaced
with, the function url-encode-url available since Emacs 24.3.1. The
patch attached for review will fix an Org link like e. g.
[[http://lists.gnu.org/archive/cgi-bin/namazu.cgi?idxname=emacs-orgmode&query=%252Bsubject:"Release+8.2"]]
with Emacs 24.3.1 now also for the Org export to HTML.

Some time ago I added url-encode-url already to the function
org-open-at-point. As this is not in maint and the attached patch
depends on it I intend to apply the latter only on master.

Michael
