bash completion on 4.0 broken?

Stephen Boyd· Nov 17, 2009, 06:46 UTC · lore

When I try

    git show --pretty=<TAB><TAB>

I get a list of filenames and not the list of pretty formats.

I've debugged a little and see that the cur variable in _git_show () is set to '=' when it should be '--pretty='. So it looks like something is causing the command line to be split weirdly. Looking at the bash NEWS[1] for 4.0 I see

i.  The programmable completion code now uses the same set of characters as
    readline when breaking the command line into a list of words.

which causes me to believe this is why it's broken now. I've tried removing '=' from COMP_WORDBREAKS and that shows the list of formats correctly, but then causes the entire '--pretty=' to be replaced with the selected format.

Anyone else seeing the same problem or is my system just b0rked?

$ bash --version GNU bash, version 4.0.35(2)-release (x86_64-pc-linux-gnu)

Ouch, just when I decided to use completion rather than a bunch of aliases it stops working. B0rked here 0ls0 on Fedora 12 (with git.git's next):

GNU bash, Version 4.0.33(1)-release (x86_64-redhat-linux-gnu)

Command name completion and prompt magic do work.
