Suppress linkification of external links possible?

Suppress linkification of external links possible?

[Ulf Stegemann]

Hi all,

just a quick question: Is it possible to suppress the automagical
linkification of external links? I have a document here for tutorial
purposes which is cluttered with invalid addresses like
'http://gateway.example.org'. Linkification of those addresses is rather
disturbing.

You can customize the variable org-activate-links and remove "plain"
from the list.

Hihi - it's that simple :-D

And I'm trying to ... oh please, ignore my answers in this thread :)

I am always amazed to find out how deep some people dig
into the variables :-)

You can write:

1. [[ ][http://gateway.example.org]] 
    ^^^ please note the space here
   when converted it should refer to
   http://your-server/yourfile#

2. use valid addresses ;-)

I think that automagially *not* converting will 
be disturbing ;-)
Moreover, how can the exporter engine know what are 
the correct and the incorrect addresses?

Perhaps we could write the uncorrect addresses as:

+http://gateway.example.org
^^^^

so the exporter "knows" that such links are to be 
exported litterarly dropping the "+"

Thank you for all the quick responses :)

Unfortunately, none of the proposed solutions really applies to the
problem I have (That's however entirely my fault, I should have made
things a bit clearer.).

The workarounds (except for one) concentrate on making a link caused by a
literal invalid address to become a valid link. However, what I like to
achieve is some sort of escaping that prevents org-mode from generating
a link at all (especially for HTML exporting).

Works, but still creates a link.

Unfortunately, this isn't an option.

Goes in the same direction: a link is still created.

This would work (I guess), but is AFAIK to be set globally, thus
resulting in the loss of all other plain text links.

What I was originally looking for was some sort of escape
character/special markup that would prevent creating links at all, like
\http://...\ . This would also allow us to use other markups on plain
text links, something that - AFAIK - is currently not possible (like
=\http:...\=).

what about post processing your HTML file with 
an /ad hoc/ function (called e.g. my-replace-esc-hlink [1])?

In your file.org you may write \http://gateway.org 
that is exported as:
\<a href="http://gateway.org">http://gateway.org</a>

then open your html buffer and

M-x my-replace-esc-hlink 

to cancel the "\<a href="http://gateway.org">" string

(defun my-replace-esc-hlink ()

thanks for the idea. I was also thinking about using a postprocessing,
maybe by using the completion-function when publishing. Should nothing
else work, I will probably come back to this.

Indeed, something like =http://a.com= should work, this is a bug.
I have just fixed it.

Using "=" does have a specified markup, but you can change it
or add a new markup by customizing `org-emphasis-alist'.

For example, you could make it look like this:

(("*" bold "<b>" "</b>")
  ("/" italic "<i>" "</i>")
  ("_" underline "<span style=\"text-decoration:underline;\">" "</ 
span>")
  ("=" org-code "<code>" "</code>" verbatim)
  ("~" org-verbatim "<code>" "</code>" verbatim)
  (";" org-verbatim "<i>" "</i>" verbatim))

where I have added the last line, so that

  ;http://google.com;

will be interpreted verbatim, and typeset in italic.

great ... but unfortunately it's not working here. Whenever I try to
export an org file to HTML now, I get 'org-export-normalize-links:
Invalid function: org-if-unprotected-at' (with Emacs 23 and Org Mode
versions as of this morning). This also happens with emacs -Q and a
plain `org-install'.

This is defined in org-macs.el.

Something must have gone wrong when you updated.  try removing
all .elc files, maybe recompile.

You are right, it's there and after re-installing org-mode it works like
a charm. I guess, somehow org-macs.el failed to re-compile in the first
place but I really have no idea how this happened.

Anyway, this perfectly solves my problem. Thanks you very much :)

here

Org-mode version 6.22b
GNU Emacs 23.0.90.1 (i386-mingw-nt5.1.2600) of 2009-02-01 on SOFT-MJASON

also +http://a.com+

is exported as a link  whereas +a.com+ is exported 
as strikethrough text.

is it the same bug or another?

Hi Ulf,



a dirty hackish aproach:



(defun sr-no-link (href)
  "Links, that are no links"
  "#")

(setq org-link-abbrev-alist
       '(("man"       . "http://localhost/devel/man.php?q=man&what=%s")
         ;; ... many more ...
         ("dummy" . sr-no-link))



  [[dummy:][http://gateway.example.org]]

It's still displayed as link then, but the browsers do nothing ;-)



Regards,


    Sebastian
