[SOLVED] Bash completion misbehaviour, quilt customization

[rockstorm]

I'm getting some weird behaviour from the bash completion feature. I configured quilt as is explained in the New Maintainers Guide [1], so this two lines are currently on my '~/.bashrc' file:

Code: Select all

alias dquilt="quilt --quiltrc=${HOME}/.quiltrc-dpkg"
complete -F _quilt_completion -o filenames dquilt

But it does not work as expected. I get:

Code: Select all

$ dquilt [Tab]
$ dquilt bash: completion: function `_quilt_completion' not found

quilt completion works fine:

Code: Select all

$ quilt [Tab]
add        edit       grep       mail       previous   revert     top
annotate   files      -h         new        push       series     unapplied
applied    fold       header     next       refresh    setup      upgrade
delete     fork       import     patches    remove     shell      
diff       graph      init       pop        rename     snapshot

I made sure the function is actually called "_quilt_completion" by looking at the quilt completion file, '/usr/share/bash-completion/completions/quilt", has this lines:

Code: Select all

_quilt_completion()
[...]
_quilt_complete_opt="-o filenames"
complete -F _quilt_completion $_quilt_complete_opt quilt
unset -v _quilt_complete_opt

So the function exists but it is somehow not finding it. But where it gets really weird is, if I run quilt and then the alias dquilt it works as expected for both:

Code: Select all

$ quilt [Tab]
add        edit       grep       mail       previous   revert     top
annotate   files      -h         new        push       series     unapplied
applied    fold       header     next       refresh    setup      upgrade
delete     fork       import     patches    remove     shell      
diff       graph      init       pop        rename     snapshot   
$ dquilt [Tab]
add        edit       grep       mail       previous   revert     top
annotate   files      -h         new        push       series     unapplied
applied    fold       header     next       refresh    setup      upgrade
delete     fork       import     patches    remove     shell      
diff       graph      init       pop        rename     snapshot

What am I missing? Please help, you don't realize how useful is this autocompletion thing until it fails

The completion works for me in buster.

Have you created ~/.quiltrc-dpkg?

[rockstorm]

Have you created ~/.quiltrc-dpkg?

Hi, yes I have:

Code: Select all

$ cat .quiltrc-dpkg 
d=. ; while [ ! -d $d/debian -a $(readlink -e $d) != / ]; do d=$d/..; done
if [ -d $d/debian ] && [ -z $QUILT_PATCHES ]; then
    # if in Debian packaging tree with unset $QUILT_PATCHES
    QUILT_PATCHES="debian/patches"
    QUILT_PATCH_OPTS="--reject-format=unified"
    QUILT_DIFF_ARGS="-p ab --no-timestamps --no-index --color=auto"
    QUILT_REFRESH_ARGS="-p ab --no-timestamps --no-index"
    QUILT_COLORS="diff_hdr=1;32:diff_add=1;34:diff_rem=1;31:diff_hunk=1;33:diff_ctx=35:diff_cctx=33"
    if ! [ -d $d/debian/patches ]; then mkdir $d/debian/patches; fi
fi

Any ideas on how to debug this further?

[Head_on_a_Stick]

Try adding

Code: Select all

_completion_loader quilt

just above the dquilt alias in ~/.bashrc

[rockstorm]

Yay! That works! Thanks a lot.

Any idea of why I need that line there? Have I misconfigured something?
