[Cgdb-users] TAB completion

[Dmitry S. <Dmi...@ok...>]

Hello all.

I have installed cgdb-0.4.0, and noticed that I cannot use TAB for
automatic completion from (tgdb) command prompt.

cgdb-0.3.4 had the completion feature, though it was not very convenient
-- possible variants were only shown above, but not substituted inside
the command prompt.

Does anybody have the same problems with cgdb?


...Bye..Dmitry.

Dmitry --

This is a known problem with cgdb.  It is a result of the way the cgdb
interacts with gdb.  I think that the fix is targetted for when the
gdb-mi interface is done.

It was difficult to make the completion work in place. This is a planned
feature for 1.0, although will probably not be done for some time.

Oops. Looks like you found a pretty serious bug.
I will fix this and add a testcase so that it doesn't happen again.

I'll notify you when the problem is fixed.

Thanks,

I have fixed the bug in cvs. However, there is no test case yet. I will
look into adding the testcase when I get a little more time, probably
this week.

If you really like the tab completion feature, check out the latest cvs.

Thanks,

Thank you, but TAB completion still does not work for me with CVS
version. Below are the commands I used to install cgdb.

$ CFLAGS="-Os -march=pentium3 -mfpmath=sse -msse -mmmx" ./configure
--prefix=/usr/local/cgdb-0.4.0-20031116 --disable-dependency-tracking
$ make
$ make install


Then I am entering cgdb, and pressing "he[TAB]".


This is the output of cgdb-0.3.4:

GNU gdb Red Hat Linux (5.1.90CVS-5)
[...]
This GDB was configured as "i386-redhat-linux".
(tgdb) he
help
(tgdb) he


And this is of cgdb-0.4.0-20031116:

GNU gdb Red Hat Linux (5.1.90CVS-5)
[...]
This GDB was configured as "i386-redhat-linux".
(tgdb) he
(tgdb) he


...Bye..Dmitry.

The way you are installing it seems fine. I don't know why CVS isn't
working for you.

The reason tab completion was broken was just a simple error. I rewrote
the interface to the annotate two tgdb code and I called the function
a2_command_callback instead of a2_completion_callback. You should check
to see if you have this patch in your CVS checkout. This should make tab
completion work once again.

You want to make sure that a2_completion_callback is there and not
a2_command_callback.

Doing a checkout of CVS should have given you this change. If it didn't
please let us know. Maybe there is something wrong with our CVS setup.

Yes, I think this is the reason.

Today, I have tried 'cvs update' one more time, and the file (plus some
other ones) were updated at last.

Thanks, TAB completion finally works as in 0.3.4 version.

Well, just for you to know.
Inline TAB completion (not only list of prompts) is the main feature I
really miss in cgdb. My co-worker even does not want to use cgdb due to
lack of this feature. So, may be you'll change the priority.
Anyway, thanks for the great tool!


...Bye..Dmitry.

Do you normally use GDB from the command line? or your friend ?

As far as I know, there is no front end to GDB that implements that
feature properly.

We both use it that way, and also several other people I'm working with.

May be.
So, what are you waiting for? ;)
