ego is Funtoo's official system personality management tool, designed to eventually replace the venerable eselect from Gentoo Linux. Daniel Robbins created a new meta-tool to replace eselect because eselect has a couple of design issues. It requires extensions to be written as shell scripts, which is a big limitation. With the advent of Funtoo's modular profile system, eselect profile was becoming cumbersome to use, and I needed to make the tool faster and more feature-rich. Ultimately, shell scripts are too slow and too hard to use to implement advanced functionality.

ego is a meta-tool that works similarly to eselect. Typing ego will show a list of available commands. Some of the benefits of ego over eselect are that ego modules can be implemented in any language. In addition, the ego architecture is designed so that the modules are themselves stand-alone commands, which allows you to access these sub-commands using shortcuts. For example, epro is a shortcut for ego profile.

Versions

The origin (shortcut: o) command will tell you where a given package comes from. This is mainly a tool for developers designed to figure out where fixes should be applied.

user $ ego query origin appi
dev-python/appi::python-kit comes from flora (https://github.com/funtoo/flora)
user $ ego query origin screen
app-misc/screen::core-kit comes from kit-fixups (https://github.com/funtoo/kit-fixups)
app-vim/screen::editors-kit comes from gentoo-staging (http://git.funtoo.org/gentoo-staging/)

Bugs

The bugs command lists bugs reported on https://bugs.funtoo.org/ regarding the given atom. This allows you to quickly find out if an issue you're facing was reported recently.

user $ ego query bugs mesa
root ##r##FL-2225 Closed  [media-libs/mesa] upgrading to 10.4.4 failed
root ##r##FL-2224 Closed  [media-libs/mesa] bump new 10.4.4 version to 10.4.7

root ##r##FL-634  Closed  portage complaining that media-libs/mesa and x11-libs/cairo need openvg flag

   Warning

Currently, this feature looks for cat/pkg in the summary of the issue. This is not working well because to Jira, "media-libs/mesa" won't match ">=media-libs/mesa-9.1" for instance.
