I like Frank's suggestion, but rather than forcing the user to use a
separate file, I'd prefer to see this as a conventional htdig attribute,
whose value is a list of string triplets. E.g.:
site_passwords: pattern1 username1 password1 \
pattern2 username2 password2
Then, if the user prefers a separate file, this would work:
where the file could be a list of space or tab separated triplets:
pattern1 username1 password1
pattern2 username2 password2
This is more consistent with the way the configuration file is currently
handled. Of course, this may change if we implement the <URL ...>
mechanism for site-specific configurations.
The important thing would be for the documentation to recommend using
a separate file for this attribute, and to recommend emphatically that
in any case, files that contain clear-text passwords should always be
For handling the default case, you could just use a pattern that would
be sure to match, e.g:
http:// defuser defpassword
and leave it to htdig to pick the first pattern that matches. As long
as patterns are arranged from strictest to loosest, you can get htdig
to do what you want. (This is how the case statement in the Bourne
shell works.) Of course, we could also allow regular expressions,
as we do now with a lot of patterns in the 3.2 code.
