Hiya
I've writte a completion file for qdbus, a KDE4 interprocess communication
tool. I can't find any documentation for the command, other than that
suggested by interactive use - that is, I don't know if there are more options
that the command accepts.
The similar command in KDE3, dcop, has a completion already, but it's buggy;
in the script the command
if eval "$com >/dev/null 2>&1"
does not behave as expected; in fact, in fish the following
if eval "not-a-command"; echo "yes!" ; end
does indeed echo "yes!" -- I guess because the eval command is always
considered successful, even when the command evaluated by eval failed.
I don't think that makes sense.
The dcop script can be fixed somewhat by changing the line to
if test ( eval "$com >/dev/null 2>&1;echo \$status" ) -eq 0
as in the attached version.
One more thing: Try typing something in fish and pressing the up arrow. This
activates history search. Try pressing Ctrl-C, clearing the commandline, and
then pressing the up arrow again. The history search is still active. This is
annoying if the following happens:
- I type some command and press tab
- The completion I want isn't there e.g. because I'm in the wrong directory.
- If I'm in a directory with many files, the completions are paged so I press
esc to leave the completion list
- I press 'up' in order to return to the previous command. This is wrong,
because the command I just typed is still active, and history search gets
activated
- I press Ctrl-C to leave the history search
- I press 'up' in order to return to the previous command, but history search
i still active and I have to press Ctrl-C AND THEN return to get out.
- annoying :-o
Well I guess you can tell I like fish a lot already, despite the annoyance, so
thanks everyone, and keep it up.
