Choosing external app at runtime?

Choosing external app at runtime?

[Simon Guest]

Hi all,

When I follow a link, Org mode knows what application to use.  Except
that sometimes I want to override that choice.

For example, I have a collection of PDF files.  Mostly I want to open
them in my statically configured PDF viewer, which is fine.  But
sometimes I want to open one in Xournal, say, to annotate it.

My mail client Wanderlust will ask me in cases like this: if multiple
mailcap entries match, I get to choose when opening the attachment.

Any chance we could do a similar thing in Org mode?

cheers,
Simon

Currently we do not have this.  I can see that this could be both  
useful and annoying, if you have to answer a prompt each time.

If the choice was only offered when a C-u prefix was given, it
wouldn't be annoying.

What do you think?

cheers,

This is a reasonable approach - but I don't know how the Emacs mailcap  
interface treats multiple matches.  Who does?

Currently we use the C-u prefix to force opening a link in Emacs, but  
we can find a solution here.

A patch implementing the ability to select an application in this way  
would be seriously considered.
