Gentoo ELOG Viewer

I swear there's a command to print out only an ebuild's ELOG statement (the part that comes after an install, sometimes with vital instructions) - but I can never remember it, or find it.

Sigh.

But I just came across the ELOG viewer - let's install:

# emerge -av app-portage/elogv

and since I had already set up emerge logs, I'm ready to go:

# elogv

Very nice console output showing a sorted window of logs, and the other half of the console has the output from the selected log. Works great!

Gentoo and Bash Completion

Having the shell complete certain commands is handy, but I didn't realize I needed to explicitely enable it with Gentoo.

My latest installation had this at the end:

*
* Versions of bash-completion prior to 20060301-r1 required each user to
* explicitly source /etc/profile.d/bash-completion in ~/.bashrc. This
* was inconsistent with the completion modules which are
* enabled with eselect bashcomp. Now any user can enable the base
* completions without editing their .bashrc by running
*
* eselect bashcomp enable base
*
* The system administrator can also be enable this globally with
*
* eselect bashcomp enable --global base
*
* Additional completion functions can also be enabled or
* disabled using eselect's bashcomp module.
*
* If you use non-login shells you still need to source
* /etc/profile.d/bash-completion.sh in your ~/.bashrc.
* Note this is bash-completion.sh, not bash-completion. Lots of people
* overlook this

Following the suggestion to enable 'base' for all users:

# eselect bashcomp enable --global base

Then, following the other instruction, I looked at the .bashrc :

# cat ~/.bashrc
[[ -f /etc/profile.d/bash-completion ]] && source /etc/profile.d/bash-completion

# Midnight Commander chdir enhancement
if [ -f /usr/share/mc/mc.gentoo ]; then
. /usr/share/mc/mc.gentoo
fi

Huh - just like the instructions said, there is no '/etc/profile.d/bash-completion' file, but their is a '/etc/profile.d/bash-completion.sh' file, so I need to modify that now :

# nano ~/.bashrc

- added in the '.sh' - as occasionally I do use non-login shells.

Then looking at what options are available and selected for bashcompletion

# eselect bashcomp list
Available completions:
[1] _subversion
[2] apache2ctl
[3] base
[4] bitkeeper
[5] bittorrent
[6] cksfv
[7] clisp
[8] cowsay *
[9] django
[10] dsniff
[11] eselect
[12] freeciv
[13] gcl
[14] gentoo
[15] git
[16] gkrellm
[17] gnatmake
[18] gpg2
[19] harbour
[20] isql
[21] larch
[22] lilypond
[23] lisp
[24] mailman
[25] mcrypt
[26] modules
[27] monodevelop
[28] mtx
[29] p4
[30] povray
[31] qdbus
[32] ri
[33] rkhunter *
[34] sbcl
[35] sitecopy
[36] snownews
[37] ssh
[38] subversion
[39] tree *
[40] unace
[41] unrar
[42] vim *
[43] xxd

Looking at these, I'd definately want 'base', 'gentoo' and 'eselect' going, and whatever else looks interesting - subversion, ssh, eix, genlop,.

Looking at another server, I saw this:

# eselect bashcomp list
Available completions:
[1] cowsay *
[2] eselect *
[3] genlop *
[4] git
[5] subversion

Hmm a very short list - I didn't have 'bash-completion' installed, although the USE flag had been set - better install it now:

# emerge -pv app-shells/gentoo-bashcomp

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild N ] app-shells/bash-completion-20081219-r1 90 kB
[ebuild N ] app-shells/gentoo-bashcomp-20050516 20 kB

Total: 2 packages (2 new), Size of downloads: 109 kB

# emerge -av app-shells/gentoo-bashcomp

Now my 'eselect bashcomp list' command results look better.

To immediately get the bash-completion going, simply run it:

# /etc/profile.d/bash-completion.sh

(This worked in one session, but not the other - you may have to start a new terminal session to get this going properly.)

Now I get great autocompletion for 'emerge' and many other commands:

# emerge [hit 'TAB' key after typing in a space after 'emerge']

Woohoo - looks good and will be very handy in the long run.

Some handy sites I found along the way:

which were all blogs - looks like blogs are becoming the best places to go for small howto's and general answers - good work everyone ;D
