Protocols and filenames

Protocols and filenames

[Sebastian Rose]

Hi,


I have a question about file name expansion.

I want to open a file prefixed with a user defined protocol through
emacsclient. Just like 

  emacsclient my-protocol:///home/sebastian/org/tutorials/tutorial.org


* First question:

   while this here works:
   C-x C-f file:///home/sebastian/.emacs RET

   this here does not:
   $ emacsclient file:///home/sebastian/.emacs

   Why?

   The file is opened as

   /current/working/directory/file:/home/sebastian/.emacs
   
   Seems odd. Quoting does not help.



* Second question:

   How would get emacs to open a file using a user defined protocoll
   like this:

   emacs my-protocol:///path/to/tutorial.org

   I tried to use `directory-abbrev-alist' for this, but to no avail.



emacs-version:

GNU Emacs 23.0.91.1 (i686-pc-linux-gnu, GTK+ Version 2.12.11) of 2009-03-03 



Thanks in advance,

Indeed, we have a bug here.  `emacsclient' passes
`pwd`/my-protocol:///home/sebastian/org/tutorials/tutorial.org to Emacs,
which is why it doesn't work.

You'd either want to use file-name-handler-alist, or even hook directly
into the URL library (see emacs/lisp/url/*.el).
