"*Default actions to be taken when the user asks to view a file.
|
||
To change the behaviour, you can either edit this variable or set
|
||
`gnus-uu-user-view-rules' to something useful.
|
||
|
||
For example:
|
||
|
||
To make gnus-uu use 'xli' to display JPEG and GIF files, put the
|
||
following in your .emacs file:
|
||
|
||
(setq gnus-uu-user-view-rules '((\"jpg$\\\\|gif$\" \"xli\")))
|
||
|
||
Both these variables are lists of lists with two string elements. The
|
||
first string is a regular expression. If the file name matches this
|
||
regular expression, the command in the second string is executed with
|
||
the file as an argument.
|
||
|
||
If the command string contains \"%s\", the file name will be inserted
|
||
at that point in the command string. If there's no \"%s\" in the
|
||
command string, the file name will be appended to the command string
|
||
before executing.
|
||
|
||
There are several user variables to tailor the behaviour of gnus-uu to
|
||
your needs. First we have `gnus-uu-user-view-rules', which is the
|
||
variable gnus-uu first consults when trying to decide how to view a
|
||
file. If this variable contains no matches, gnus-uu examines the
|
||
default rule variable provided in this package. If gnus-uu finds no
|
||
match here, it uses `gnus-uu-user-view-rules-end' to try to make a
|
||
match."
