Colorizing the output of pacman

Now that makepkg has colorized output, why not pacman as well? Gentoo's package manager application named 'portage' uses colors extensively, and as you can see in this screenshot, it greatly enhances readability.

Scripts

User citral uses the following script in his .bashrc:

alias pacs="pacsearch"
pacsearch () {
       echo -e "$(pacman -Ss $@ | sed \
       -e 's#current/.*#\\033[1;31m&\\033[0;37m#g' \
       -e 's#extra/.*#\\033[0;32m&\\033[0;37m#g' \
       -e 's#community/.*#\\033[1;35m&\\033[0;37m#g' \
       -e 's#^.*/.* [0-9].*#\\033[0;36m&\\033[0;37m#g' )"
}

Which is the cleanest solution. However, if you desire a system-wide script, do as root:

 touch /usr/bin/pacs && chmod 755 /usr/bin/pacs

and then paste this into /usr/bin/pacs as root:

 #!/bin/bash
 echo -e "$(pacman -Ss $@ | sed \
 -e 's#current/.*#\\033[1;31m&\\033[0;37m#g' \
 -e 's#extra/.*#\\033[0;32m&\\033[0;37m#g' \
 -e 's#community/.*#\\033[1;35m&\\033[0;37m#g' \
 -e 's#^.*/.* [0-9].*#\\033[0;36m&\\033[0;37m#g' )"

You can substitute "pacs" in these lines for anything you like. You can also alias "pacs" to something else in your .bashrc, as done above.

Using these commands is straightforward; simply use your new command instead of 'pacman', the rest is still the same!

Alternatives

qpkg in AUR also uses colored output and searches AUR and TURepositories too!

Yet another alternative is to use this script, it emulates the output of pacman -Ss (with color!) but fetches the package list from the web instead. It searches the official repositories and AUR (both community and unsupported). Needs curl to be installed.

#!/bin/bash
QUERY="$1"
SEARCH="http://archlinux.org/packages.php?s_keyword=$QUERY"
echo -e "$(curl -sN $SEARCH | grep data \
 | sed -e '0~6d' \
 -e 's|<[^>]*>||g' -e 's|^[ \t]*||g' \
 -e '1~6s|$|/|g' -e '2~6s|$|   |g'  -e '3~6s|$| |g' \
 -e '5~6s|$|NEWLINE|g' \
 -e '4~6s|$|\\033[0;0mNEWLINE|g'\
 -e 's|^Testing|\\033[1;31m&|g' \
 -e 's|^Current|\\033[1;32m&|g' \
 -e 's|^Extra|\\033[1;36m&|g' \
 -e 's|^Unstable|\\033[1;31m&|g' \
 | tr -d '\n' | sed 's/NEWLINE/\n/g')"
SEARCH="http://aur.archlinux.org/packages.php?K=$QUERY"
echo -e "$(curl -sN $SEARCH | grep data \
 | sed -e '0~6d' -e '4~6d' \
 -e 's|<[^>]*>||g' -e 's|^[ \t]*||g' \
 -e '1~6s|$|/|g' -e '2~6s|$|   |g' \
 -e '5~6s|$|NEWLINE|g' \
 -e '3~6s|$|\\033[0;0mNEWLINE|g' \
 -e 's|^community|\\033[1;33m&|g' \
 -e 's|^unsupported|\\033[1;35m&|g' \
 | tr -d '\n' | sed 's/NEWLINE/\n/g')"

Using 'acoc'

There is another, more general possibility of colorizing arbitrary command output. You can download the small Ruby tool acoc (and its requirements, term-ansicolor and tpty. ). tpty is not really required, but some applications like "ls" won't run with acoc otherwise (they need to be started from a terminal (or pseudo terminal, in this case), or else they behave differently).

Installation is relatively straightforward, here's a quick walkthrough:

$ tar xvzf tpty-0.0.1.tar.gz
$ cd tpty-0.0.1
$ ruby extconf.rb
$ make
$ ruby ./test.rb
# make install
$ tar xvzf term-ansicolor-1.0.1.tar.gz
$ cd term-ansicolor-1.0.1
# ruby install.rb

And now acoc itself:

$ tar xvzf acoc-0.7.1.tar.gz
$ cd acoc-0.7.1
# make install

Now, just read the section "Advanced Installation" in acoc's INSTALL file, and configure acoc as you want to. Create a link for 'pacman' as well, since that's primarily what we're doing this for. Once acoc runs, you can add these lines to your acoc.conf:

[pacman -Si]
/^Name\s+:\s([\w.-]+)/                              bold
[pacman -Qi]
/^Name\s+:\s([\w.-]+)/                              bold
[pacman -Qi$]
/^([\w.-]+)\s([\w.-]+)/                 bold,clear
[pacman -Ss]
/^([\w.-]+)\/([\w.-]+)\s+([\w.-]+)/     clear,bold,clear
[pacman -Qs]
/^([\w.-]+)\/([\w.-]+)\s+([\w.-]+)/     clear,bold,clear
[pacman -Sl]
/^([\w.-]+)\s([\w.-]+)\s([\w.-]+)/              clear,bold,clear
[pacman -Qo]
/^([\w.-\/]+)\sis\sowned\sby\s([\w.-]+)\s([\w.-]+)/     clear,bold,clear
[pacman -Qe$]
/^([\w.-]+)\s([\w.-]+)/                 bold,clear
[pacman -Qg$]
/^([\w.-]+)\s([\w.-]+)/                 clear,bold

It might not be perfect, or particularly nice, but so far it works fine for me. The above lines just make pacman print all package names in bold, which is particularly helpful when doing e.g. "pacman -Ss xfce". If you like it more colorful, you can modify the lines as you want. Read the acoc documentation contained in the source package for more information.
