[gentoo-user] emerge bash-completion

[Behrouz Khosravi]

hello everyone. I have a problem with bash-completion with emerge 
command for packages. when I press tab-tab it only shows "world" and 
"system" but I was working OK before, I mean It was able to show the list of 
packages. Is anything changed?

It does that here, but it seems I need to press tab three times, not two.

well three times did not change anything. The problem is that I cant 
remember since when this feature is broke, so I can relate it to something!

Well, it could be that you have a mix of the old bashcomp system 
together with the new one and that cause issues.

If that is the case, then in order to completely transition to the new 
system, you would have to re-emerge everything that installs bashcomp 
files. Also, delete all your bashcomp eselect files. The new system has 
everything enabled by default and eselect is used to actually disable 
bashcomp for all packages and whitelist the only you enable. This can 
cause problems if you have old and new files lying around.

I think there was a news item on how to transition from the old to the 
new setup. No idea where to find it if you don't have it in "eselect 
news list" anymore :-/

Thanks for this.  I'm not the OP, but broken bash completion has
been bothering me for a while.  Somehow I'd gotten the mistaken
impression that it was supposed to heal itself over time as the
programs that install bashcomp files were rebuilt with updates, without
me having deal with any cruft.

At the time, I was on the lookout for such a news item and I never saw
one.  Always possible that was my fault, but I really think there was
no such item.

Also, if I've correctly understood what you wrote above,
<https://wiki.gentoo.org/wiki/Bash#Tab_completion> needs an overhaul.
(Conversely, if it doesn't need an overhaul, my understanding is still
faulty and I'll be back for some hand-holding!)

There was a news item, I've pasted the whole thing here for you

2014-11-25-bash-completion-2_1-r90
  Title                     bash-completion-2.1-r90
  Author                    Michał Górny <mgorny@gentoo.org>
  Posted                    2014-11-25
  Revision                  1

Starting with app-shells/bash-completion-2.1-r90, the framework used to
enable and manage completions in Gentoo is finally changing in order to
properly follow upstream design. This has some important implications
for our users.

Firstly, the install location for completions changes to follow upstream
default. The completions enabled before the upgrade will continue to
work but you may no longer be able to enable or disable completions
installed prior to the upgrade. To solve this issue, the packages
installing completions need to rebuilt. The following command can be
used to automatically rebuild all the relevant packages:

$ find /usr/share/bash-completion -maxdepth 1 -type f \
        '!' -name 'bash_completion' -exec emerge -1v {} +

Secondly, the autoloading support introduced upstream removes the
penalties involved with enabling a great number of completions. This
allowed us to switch to an opt-out model where all completions installed
after the upgrade are enabled by default. Specific completions can be
disabled using 'eselect bashcomp disable ...'

The model change implies that all current selections done using 'eselect
bashcomp' can not be properly migrated and will be disregarded when
the relevant completion files are built against the new bash-completion
version. After rebuilding all the packages providing completion files,
you may want to remove the symlinks that were used to configure
the previous framework using the following command:

$ find /etc/bash_completion.d -type l -delete

Thirdly, we have solved the issue causing bash-completion support to be
enabled by default on login shells only. If you needed to explicitly
source 'bash_completion' script in bashrc, you can safely remove that
code now since system-wide bashrc takes care of loading it.

Lastly, we would like to explain that USE=bash-completion is being
removed from packages for the completions will be installed
unconditionally now. However, this will result in some implicit
dependencies being removed. Most specifically, users wishing to use
bash-completion will have to request app-shells/bash-completion
explicitly, e.g.:

$ emerge -n app-shells/bash-completion

Thank you very much.

And the wiki page section I cited is quite correct for stable users.

AIUI now, the situation boils down to:  Stable bash-completion is old
and broken, and new better bash-completion is in place but not yet
marked stable.

If that's not right, I beg for another correction, please.  :)

The P means it is in the portage tree.  The I means that it is
installed.  Based on your info, you are using a older version of
bash-completion than I am.

Thanks, Are you on ~AMD64 ?
My version is the last in stable.
I added keyword, but It will install newer version of bash too. Is it stable ?

I'm using this version of bash, which I'm sure is the keyworded version.

app-shells/bash-4.3_p33-r2

I don't know of any issues so I guess it is OK but your system may be
different too. 

This was mentioned in another reply but I'm putting the info here for
you.  This is the news item for this which could be the problem.

  Posted                    2014-11-25
  Revision                  1

Starting with app-shells/bash-completion-2.1-r90, the framework used to

for our users.

Firstly, the install location for completions changes to follow upstream

The model change implies that all current selections done using 'eselect

 Thank you. I installed that and saw the news too.
It is working again, but it seems I have a lot to rebuild!

I'm happy to retract my seconds-ago post saying I didn't think there
was a news item.  Earlier today, I was chastising someone (mildly I
hope) in another venue for not reading all new posts in a thread before
jumping in, so I guess it was inevitable I would do the same damned
thing.

Thanks, Dale. :)
