Package: devscripts
Version: 2.15.9
Severity: important
Dear Maintainer,
I was trying to understand the bash completion code. I found that now that
the devscripts bash completions don't work. For example
chdist<TAB>
should produce
nicholas@chilcott:~$ chdist
apt-cache compare-bin-packages create src2bin
apt-get compare-bin-versions grep-dctrl-packages
apt-rdepends compare-packages grep-dctrl-sources
bin2src compare-versions list
but instead just shows whatever files are in the current directory.
I found really three issues:
1. Firstly the scripts are now in the directory
/usr/share/bash-completion/completions .
The scripts in this directory are autoloaded and expected to work slightly
differently.
So this must be named with the name of the command they are providing a
completion for.
So the following links are required:
ln -s devscripts.chdist chdist
ln -s devscripts.dcut dcut
ln -s devscripts.debchange debchange
ln -s devscripts.debchange dch
ln -s devscripts.debsign debsign
ln -s devscripts.mk-origtargz mk-origtargz
for i in wnpp-alert wnpp-check mk-build-deps rmadison mass-bug debsnap dd-list
build-rdeps who-uploads transition-check getbuildlog dcontrol grep-excuses
rc-alert bts whodepends dget pts-subscribe debc pts-unsubscribe
do
ln -s devscripts.pkgnames $i
done
ln -s devscripts.uscan uscan
ln -s devscripts.uupdate uupdate
2. Some of the scripts (chdist dch dcut debsign uupdate) use a deprecated
"have" mechanism.
To preserve name space purity this is replaced by "_have". That notwithstanding
it does not seem
to work. A typical case is uupdate:
nicholas@chilcott:/usr/share/bash-completion/completions$ diff uupdate.old
uupdate
1d0
< have uupdate &&
32c31
< [ "$have" ] && complete -F _uupdate -o filenames uupdate
---
> complete -F _uupdate -o filenames uupdate
3. The chdist script seems to have an additional issue.
nicholas@chilcott:/usr/share/bash-completion/completions$ diff chdist.old chdist
1d0
< have chdist &&
50c49
< [ -n "${have:-}" ] && complete -F _chdist $filenames chdist
---
> complete -F _chdist chdist
I am not quite sure where "$filenames" comes from. As far as I can see from git
it has always been there, but it is not as far as I can see defined. It might
be intended
to be "-o filenames" as with other completions though I do not really think
that makes sense.
