Enlightenment, also known simply as E, is a compositing window manager for the X Window System. Since version 20, Enlightenment is also a Wayland compositor.[3] Enlightenment developers have referred to it as "the original eye-candy window manager."[4]

Enlightenment includes functions to provide a graphical shell and can be used in conjunction with programs written for GNOME or KDE. When used together with the Enlightenment Foundation Libraries (EFL), Enlightenment can refer to an entire desktop environment.[5]

History

The first version of Enlightenment was released by Rasterman (Carsten Haitzler) in 1997.[6]

Version 0.17, also referred to as E17, was in development for 12 years starting in December 2000[7] until 21 December 2012 when it was officially released as stable.[8] During the development period it was also referred to as DR17 (Development Release 17). It is a complete rewrite on DR16 and was designed to be a full-fledged desktop shell, based on the new Enlightenment Foundation Libraries (EFL).

E16 itself is still in active development that runs independently of E17, reaching the 1.0 milestone in 2009 (1.0.27 as of 2023).[9]

Bodhi Linux was built around the Enlightenment 17 desktop, but forked it to create the Moksha desktop. Elive Linux also used a fork of E17 as its main desktop environment until 2019, when the 3.7 series was released.

The current version is E25.[10]

Version history

E16

E16 provides features that is not present in most "advanced" desktop environments to this day. It allows the user to create a grid of workspaces known as "virtual desktops". Switching between them is achieved by hurling the mouse cursor to the edge of the screen, after which the desktop appears to slide across to reveal the next. All the desktops are connected, meaning that if a window is too big for the screen size, the user can go to the adjacent desktops to find the rest of it. There can be 8 by 8 desktops in a grid, and up to 32 grids are possible (each can have a different background), making 2048 possible workspaces. Users can enable a "map" of the desktops, called the pager, in case they get lost. It also provided the ability to put windows in groups (so they can be removed, resized, closed, etc all together), "iconification" which is similar to minimizing but are stored in "iconboxes" that can be moved, the ability to change the type of or remove completely the borders and title bars, advanced keybinding settings to allow use of Enlightenment solely with a keyboard (e16keyedit is a GUI program simplifying this process), a scriptable command-line interface that works with most if not all of E's features, and (with newer versions) a compositor with effects such as fading and transparency.

One of the aims of the window manager is to be as configurable as possible, and to this end, it includes customization dialogs for focus settings, window movement, resizing, grouping and placement settings, audio, multiple desktop, desktop background, pager, tooltip and autoraise settings. It also includes a special effects dialog, with two effects, one of which being a desktop 'ripple' effect.[11]

E17

DR17 with former default theme Bling-bling. The theme was superseded by Black and White

E17 is fully themeable with both a menu-based and command-line theme-changing interface. It boasts a built-in file manager, adds icons to the desktop (for example, anything in the user's Desktop folder will show up), and a virtual desktop grid feature similar to that of E16. It also has a modular design, enabling it to load external modules. Examples of available modules are the Pager, the iBar (a sort of taskbar), an iBox holding minimized applications, a dock, a compositor, and more. E17 also adds one or more shelves to manage gadget placement and appearance. Animated and interactive desktop backgrounds, menu items, iBar items, and desktop widgets are also possible, as are window shading, iconification, maximizing, sticky settings, customizable key bindings, internationalization, and a screenshot menu. Finally, E17 conforms to all needed standards (NetWM, ICCCM, XDG, and so on).

E17's data files (such as configurations and themes), unlike E16 (which uses JSON) are in a binary format, making them significantly faster than their JSON counterparts.[12]
