And it gets worse: The gdbus one requires _get_cword() from a Debian
package called bash-completion-lib. Grub requires 2 more from the same
package: filelist(), _get_longopt(), and _filelist() is dependent on
_expand(). There was a Google code project
(http://code.google.com/p/bash-completion-lib/) that doesn't cover
_split_longopt() (following). Last release was in Feb of 2009, but I
haven't found where the Debian one is developed yet.
# This function splits $cur=--foo=bar into $prev=--foo, $cur=bar, making it
# easier to support both "--foo bar" and "--foo=bar" style completions.
# Returns 0 if current option was split, 1 otherwise.
#
_split_longopt()
{
if [[ "$cur" == --?*=* ]]; then
# Cut also backslash before '=' in case it ended up there
# for some reason.
prev="${cur%%?(\\)=*}"
cur="${cur#*=}"
return 0
fi
return 1
}
Just leave it unconfigured in LFS? I'll try and get something into the
BLFS wiki, not sure whether the full package, or just the known needed
functions. With just a base LFS, only 5 functions are required for bash
completion to work as the developers intended.
