etools

bash library for gentoo utils

How to use

Just source it!

source etools

What it does

provided function are the following:

einfo <info>
ewarn <warning>
eerror <error>
etools_configure
etools_unset
etools_smart_find <package name> [repo]
# repo can be a path relative to /var/db/repos/ or a full path
# default will be /var/db/repos/ so all repos will be searched
eools_get_version <package name> [offset]
# offset will output the <offset> latest version
# eg.: when 1.2.3 is latest offset 1 will result in a version 1 beneath 1.2.2-r2 for example
# btw feel free to time both of them ;)

Configuration

etools searches for a configuration file at the following locations:

/etc/etools/etools.conf
$HOME/.config/etools.conf
$HOME/.config/etools/etools.conf

Look at the exmaple configuration file for an example with all configuration options.

For the default values take a look at config.sh.

NOTE: Letting already set options fallback to defaults will not work, as defaults only get set when the relative variables are undefined. To force reload:

etools_unset
source etools

Motivation

They say "A picture is worth a thousand words", so here ya go:

Test it

This script reads all packages in your world file and runs etools_smart_find with the name of the package

while IFS= read -r line; do
    if [[ ${line%% *} == ${line##* }  ]]; then
        echo -e "${line%% *} \e[32mpassed\e[0m";
    else
        echo -e "${line%% *} \e[31mFAILED\e[0m";
    fi;
done <<< $(
    for pkg in $(cat /var/lib/portage/world); do
        echo -n "$pkg ";
        etools_smart_find $(echo $pkg | awk -F'/' '{print $2}');
    done
);
