Package: bash-completion
Version: 1:1.3-1
Severity: normal
Tags: patch
When trying to complete the name of a script after "-d", I get no
completions. E.g.:
perl -d <tab>
The problem is that there are two cases:
1. We are at "-d*", so we shift that into $prev, put the rest of it in
$cur, and then look for ":*" in $cur.
2. We are at "-d ", and $prev remains "-d", but we still try to look
for ":*" in $cur.
So case (2) is wrong; we will complete "-d :DProf", which doesn't make
any sense (and isn't accepted by perl). And if you have no colon, you
get no completions at all.
There is a similar problem for "-V:" and "-M" (which will complete "-M
module", which perl complains about).
The attached patch fixes it for me. It looks for options in
$prev only if we did the $cur/$prev shift, and otherwise completes as
normal.
