[gentoo-dev] Bash completion for emerge

[gentoo-dev] Bash completion for emerge

[-- Attachment #1: Type: text/plain, Size: 527 bytes --]

Hi all,

as a diversion I amused myself by trying out the bash programmable
completion. I currently have it working for emerge. I'm not a bash
expert and surely this code can be written in a much better way, but it
already works.

To use it, just add the atachment to /etc/bash_completion.

Hope this is of some help to someone,

Geert

Imho, we should add this to the default bash-installation? 
What do you think?

One of the earlier versions I wrote actually did this. It's on the 
ebuild mailing list. It also contains a patch for bash that offers some 
functionality for service completion on /etc/init.d. Just let me know 
what you would like. I'm at your disposal.

Let's hold off for a little bit.  Maybe in a week or so.

Hmmm ... your bash_completion post contains completions for emerge and
ebuild? I must be looking over it 'cause I can't find it. I'd like to
see how you implemented it, would be good see which version performs
best.

Sorry, I think I misunderstood what you had said. I meant that I had 
originally modified the bash package to install bash_completion at the 
same time.
