file link format question - How to format link when square brackets [ ] are already in filename?

file link format question - How to format link when square brackets [ ] are already in filename?

[Erwin Panen]

Hi everyone,

I guess this is a minor question, but it has puzzled me already more 
than once.
My example: The below example is normally all on one line.
---------------Begin code----------------------------------------------
** Action: started to play video 
[[\\Dcerouter\public\videos\STORY_Station (sdb1)-CORE [32]\Les Rivières 
Pourpres 720x304\The Crimson Rivers.mkv][The Crimson Rivers.mkv]]
---------------End code------------------------------------------------

The problem is that the file location already contains a number between 
square brackets [32] which renders Org to treat the link in an 
unsuspected way.

Is there any way to circumvent this behaviour e.g. by inserting special 
characters to avoid Org to look inbetween the special characters?

Looking forward to a solution :-)

Thanks,

Erwin

You can url-encode the square brackets with %5B ("[") and %5D ("]") --
orgmode does this when calling `org-store-link' (C-c l) for a place
that contains square brackets and opens the links fine.

Hi David,

Thanks for replying;
I don't understand what you mean. I was not aware off url-encoding, but 
found help here: 
http://www.eskimo.com/~bloo/indexdot/html/topics/urlencoding.htm 
<http://www.eskimo.com/%7Ebloo/indexdot/html/topics/urlencoding.htm>
So far so good.
The way I interpret this is that I can 'replace' [square brackets] in 
orgmode  with %5Bsquare brackets%5D
However when I try this, org does not 'convert' to a link...? What am I 
missing?

Perhaps for clarification:
The link I used in my example may be confusing, it is a long UNC path to 
a file on a network server that has somewhere [32] in it's name.
It's the [32] that seems to confuse org's linking.
I also noticed when hovering over [32] that org seems to recognize this 
as a footnote??

Thanks,

Erwin

That's exactly what I meant. The behaviour you notice when /not/
encoding the square brackets is absolutely correct because of the way
Orgmode works: If you display a file in org-mode, the Orgmode
functions interpret the file's content and change the way certain
portions of the file look ("folding" of the link, i.e. only display
the description) and what you can do on this regions (i.e. open the
link).

So there is for instance a pattern that "tells" Orgmode that something
is a link: [[<some characters][<some other characters>]] is recognized
as a link with a target (first set of characters) and a description
(second set of characters). If there are literal square brackets in
either the description or the target, Orgmode simply does not
recognize the string as a link.

The same principle (interpreting strings/a sequence of characters)
causes Orgmode to recognize the [32] as a footnote. Why? Because there
is a definition that says the "a number between two square brakets is
a footnote".

Strange. What Emacs and Orgmode version do you use?[1] I use 

"GNU Emacs 23.1.92.1 (i486-pc-linux-gnu, GTK+ Version 2.18.6) of
 2010-01-31 on elegiac, modified by Debian"

with

"Org-mode version 6.34trans (release_6.34c.65.g45c58)"

For me encoding the square brackets in the link name with %5B and %5D
works. That is: Emacs/Orgmode "collapses" the link and only displays
the description part.

[1] To find out your version simply execute "org-version" (M-x
org-version RET) and "emacs-version" (M-x emacs-version RET) and
switch to the buffer called "*Messages*" to see the version strings of
Emacs and Orgmode.

David, thanks for clarifying :-)
I think I get it now.
Your example helps!

What I did (wrongly) was to exchange the outer brackets with %5B and %5D
Instead I should have exchanged the brackets enclosing 32
I get an error of the file not found now, but at least Emacs/org does 
fold the link now and only leaves the description!

I guess I'll figure out the missing file problem.

Thanks very much for helping out!
