Bug 994659

AFAIK there's nothing that can be done about this in bash-completion, it's a bash thing -- our completion functions simply aren't invoked in those kinds of command lines:

$ foo() { echo ; echo "in foo"; }
$ complete -F foo foo

$ foo <TAB>
in foo

$ foo=bar foo <TAB>
# filename completion occurs

I'm not much familiar with bash completion, but this looks like missing feature.

I will take a look on it.

Thanks, Roman.

The journalctl completions are in the systemd package, not the bash-completion package:

$ rpm -ql systemd | grep completions/journalctl
/usr/share/bash-completion/completions/journalctl

Steve BTW this has nothing to do with the bash-completion or journalctl packages or completions, see comment 1.

FYI, Comment 3 was an FYI. :-)

Presumably some completions will need to be installed to test the bash fixes. Or am I mistaken? Can completions be tested without completions?

Comment 1 contains a completion for command foo, no need to install anything besides entering those two lines and start testing.

Thanks for your clarification. That's very interesting. bash has a lot of features I don't know anything about ...

$ fo[tab]
fold          font2c        fonttosfnt    foo           foomatic-rip  foo.sh        for           formail       
$ foo[tab]
foo           foomatic-rip  foo.sh        
$ foo [tab]
in foo
[tab]
in foo
[enter]

in foo
$

$ complete | grep foo
complete -F foo foo
$ 
$ typeset -f foo
foo () 
{ 
    echo;
    echo "in foo"
}
$

In this case the bash is trying filename completion. It could be somehow doable to learn bash (readline) to perform command completion.

I'm testing bash-4.3-beta from upstream testing branch and this feature is working.
It will appear in next release of bash.

What test case are you using?

$ foo() { echo ; echo "in foo"; }
$ complete -F foo foo

$ TZ=UTC fo[tab] # completion does not occur here

$ fo[tab] # this works as expected
fold          font2c        fonttosfnt    foo           foomatic-rip  foo.sh        for           formail       

$ echo $BASH_VERSION               
4.3.0(1)-beta

bash-4.3-beta.tar.gz downloaded from here:
http://git.savannah.gnu.org/cgit/bash.git/

$ TZ=UTC foo[tab] # this appears to work
in foo
[enter]

in foo
$

You're right.
Even worse, it only completes using programmable completions - it doesn't complete for binary files in PATH.

This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.

Hi and thanks for the report.
This issue is now fixed in bash-4.3, which can be found in rawhide.
