Summary: DBTS 336987: shell variables should always be a valid completion when
syntactically valid
Distribution: None
Originally reported in: Debian BTS
Milestone: None
Status: None
Original bug number: 336987
Initial Comment:
Normally, bash can complete shell variables when appropriate; for
example, "foo=1" followed by "echo $f<TAB>" will complete to "echo
$foo". However, programmable completion interferes with this; for
example, "svn ls $f<TAB>", "cvs $f<TAB>", and "ssh $f<TAB>" all fail to
complete $foo. Shell variables should always be a valid completion when
they are syntactically valid, since they could always contain a string
appropriate for the current command.
(By "when they are syntactically valid", I mean that the shell already
knows not to complete "echo \$f<TAB>" into "echo \$foo", and that
shouldn't change.)

Message:
Anyone have a workaround for this issue?
Another couple examples where this is not working:
"ls -l $HOM<TAB>" fails to complete to "ls -l $HOME"
"du $HOM<TAB>" fails to complete to "du $HOME"
however this does work
"ls -l $HOME/<TAB>"
"du $HOME/<TAB>"

Message:
I was looking for a way to wrap $(complete) and make it call
a "variable_complete" before each specific completion
But I don't see any way to do it.
So my point of view is that we have to use the
dirty way and wish bash will make the completion
more smooth one of these days.
# copied from _cd()
comp_variables() {
# try to allow variable completion
if [[ "$cur" == ?(\\)\$* ]]; then
COMPREPLY=( $( compgen -v -P '$' -- "${cur#?(\\)$}" ) )
return 0
fi
}
and call it in each completion... :S
