Subject: Bash completion: add support for --list=format-methods[:WHICH]
This was intended for bleeding, but the patched bash completion script
should work well with formats which don't have this new option.
Now that the --list=format-methods[:WHICH] is implemented in
magnum-jumbo, this patch should be applied to magnum-jumbo as well.
Otherwise,
$ ./john --list=format-m
would get completed to
$ ./john --list=format-methods[:WHICH]
The new script will use only the substrings up to '[' or ':' (whichever
comes first) for completion.
Currently, for expansion of method names I use the hard coded obtained
from bleeding using
$ ./john --list=format-methods|sed -n '/^\s/ s#^\s*\([^(\[]*\).*$#\1#
p'|sort -u
I didn't want to do that every time someone wants to complete a method
name, that's why a hard coded list.
Side effect for jumbo:
$ ./john --list=format-methods:get_[tab][tab]
get_hash get_key get_source
But, of course, get_source is invalid for magnum-jumbo.
$ ./john --list=format-methods:get_source
Error, invalid option (invalid method name) format-methods:get_source
I consider the hard coded list a q&d workaround.
Should a new --list=method-names be implemented, or should I rather use
./john --list=format-methods|sed -n '/^\s/ s#^\s*\([^(\[]*\).*$#\1#
p'|sort -u
in my script.
I tested it, the run time is not too bad.
Still, the new bash completion script is better than the old one even
for jumbo.
