@ -1477,9 +1477,38 @@ you can use this variable to set the application for a given file
extension. The entries in this list are cons cells where the car identifies
files and the cdr the corresponding command. Possible values for the
file identifier are
\"regex\" Regular expression matched against the file name. For backward
compatibility, this can also be a string with only alphanumeric
characters, which is then interpreted as an extension.
\"string\" A string as a file identifier can be interpreted in different
ways, depending on its contents:
- Alphanumeric characters only:
Match links with this file extension.
Example: (\"pdf\" . \"evince %s\")
to open PDFs with evince.
- Regular expression: Match links where the
filename matches the regexp. If you want to
use groups here, use shy groups.
Example: (\"\\.x?html\\'\" . \"firefox %s\")
(\"\\(?:xhtml\\|html\\)\" . \"firefox %s\")
to open *.html and *.xhtml with firefox.
- Regular expression which contains (non-shy) groups:
Match links where the whole link, including \"::\", and
anything after that, matches the regexp.
In a custom command string, %1, %2, etc. are replaced with
the parts of the link that were matched by the groups.
For backwards compatibility, if a command string is given
that does not use any of the group matches, this case is
handled identically to the second one (i.e. match against
file name only).
In a custom lisp form, you can access the group matches with
(match-string n link).
Example: (\"\\.pdf::\\(\\d+\\)\\'\" . \"evince -p %1 %s\")
to open [[file:document.pdf::5]] with evince at page 5.
`directory' Matches a directory
`remote' Matches a remote file, accessible through tramp or efs.
Remote files most likely should be visited through Emacs
