{{c|ego}} (aka personality) is master program used to manipulate Funtoo system settings. It is present in base system, and in every stage3. It consist of various modules, which serve for view, change and control a basic system. Below we describe ego's module called <code>epro</code> which, one may guess, is a profile manager.
{{c|ego}} is Funtoo's official system personality management tool, designed to eventually replace the venerable {{c|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, {{c|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.


=== Usage ===
{{c|ego}} is a meta-tool that works similarly to eselect. Typing {{c|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, {{c|epro}} is a shortcut for {{c|ego profile}}. Please see the [[Funtoo Profiles]] page for detailed documentation on {{c|ego profile}}.
[[Funtoo 1.0 Profile|Funtoo profiles]] are used to define defaults for Portage specific to your needs. There are five basic profile types: arch, build, subarch, [[Flavors and Mix-ins|flavor, and mix-ins]]:


;arch: typically <code>x86-32bit</code> or <code>x86-64bit</code>, this defines the processor type and support of your system. This is defined when your stage was built and should not be changed.
== Ego Modules ==
;build: defines whether your system is a <code>current</code>, <code>stable</code> or <code>experimental</code> build. <code>current</code> systems will have newer packages unmasked than <code>stable</code> systems. This is defined when your stage is built and is typically not changed.
;subarch: Defines optimizations for your CPU. The subarch is set at the time the stage3 is built, but can be changed later to better settings if necessary. Be sure to pick a setting that is compatible with your CPU.
;flavor: defines the general type of system, such as <code>server</code> or <code>desktop</code>, and will set default USE flags appropriate for your needs.
;mix-ins: define various optional settings that you may be interested in enabling.


One arch, build and flavor must be set for each Funtoo Linux system, while mix-ins are optional and you can enable more than one if desired.

Remember that profiles can often be inherited. For example, the <code>desktop</code> flavor inherits the <code>workstation</code> flavor settings, which in turn inherits the <code>X</code> and <code>audio</code> mix-ins. You can view this by using {{c|epro}}:

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. Please see the Funtoo Profiles page for detailed documentation on ego profile.

Query module

ego query module is a tool to display information about packages. Bellow are described the various available commands.

Versions

The versions (shortcut: v) command lists all available versions matching a given atom. For each version, it also shows its slot and repository (along with git branch if any). 

user $ ego query versions python

                  2.4.1|    0| dev-kit/master


Installed versions are in bold and marked with a star.

Origin

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

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

When the package is also available in Gentoo, the URL to the Gentoo repository is also shown in cyan as you may want to compare Funtoo version with Gentoo's.

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 www-client/chromium
root ##r##FL-4233 2017-09-21 Closed Unable to emerge the package 'www-client/chromium' due to a missing dependency
