Ecore

BSD 2-Clause license

This is the core main-loop, system events and execution layer. This handles running the main loop, integrating with external data and timing sources (the system clock, file descriptors, system signals), and producing an event queue, walking that queue and dispatching events to appropriate callbacks.

Ecore Audio

BSD 2-Clause license

This library provides an API for audio playback and recording. It uses pulse audio underneath to handle mixing and policies. The API for this should not be considered stable right now because it relies on EO and EO is not considered finalized yet.

Ecore Cocoa

BSD 2-Clause license

This provides wrappers/abstractions around Max OS-X Cocoa APIs to help Mac porting.

Ecore Con

BSD 2-Clause license

This provides a completely event-based TCP/UDP and Unix domain socket API that integrates with the main-loop. This means no blocking to send or receive data, supporting "infinite send buffers" with storage and spooling being done by Ecore Con. It also supports SSL encryption transparently turned on or not on the same connection, certificate verification, CURL wrapping for HTTP connection usage (GETs, POSTs etc.), asynchronous DNS lookups and provides the ability to also be a server, not just a client, with the same event-based API.

Ecore Evas

BSD 2-Clause license

This acts as glue between the display target (X11, Wayland, Frame buffer, Cocoa on OSX, Win32 etc.) and Evas. It creates/provides a target for Evas to render to (a Window or Surface etc.) and feeds input events (Keyboard, Mouse, Multi-touch) into Evas, which then selects the target object and calls the callbacks. It also provides wrappers/glue for manipulating the Window/Surface.

Ecore Fb

BSD 2-Clause license

This provides virtual terminal allocation, access and handling, frame buffer information, raw input handling for keyboard, mouse and touch (via tslib).

Ecore File

BSD 2-Clause license

This provides file access convenience APIs for doing simple file operations like renames, copies, listing directories and more. It also supports file change monitoring and URL downloads.

Ecore IMF

BSD 2-Clause license

This is an input method abstraction framework to allow EFL to talk to things like SCIM, IBus, Wayland and XIM. This allows for complex text entry in languages such as Chinese, Japanese and Korean.

Ecore IMF Evas

BSD 2-Clause license

This library glues Input method support from Ecore IMF and Evas together.

Ecore Input

BSD 2-Clause license

This acts as a generic input layer where multiple display systems can post events in the same format to the event queue.

Ecore Input Evas

BSD 2-Clause license

This Routes events from Ecore Input into a given Evas canvas which will then route the event further to the destination object and callbacks.

Ecore IPC

BSD 2-Clause license

This acts as a layer on top of Ecore Con which handles entire IPC message packets, dealing with header delta compression and portability, as well as ensuring an entire message is received in one go as a single IPC message, regardless of payload data size. The entire API is event based almost exactly like Ecore Con and thus it supports all the transport layers Ecore Con supports.

Ecore SDL

BSD 2-Clause license

This acts as a wrapper/glue around SDL to handle SDL Windows as well as input events from SDL and tie them to the Ecore main-loop and event queue.

Ecore Wayland

BSD 2-Clause license

This is a glue/wrapper library to interface EFL to Wayland libraries to tie them into the Ecore main-loop and event queue.

Ecore Win32

BSD 2-Clause license

This acts as glue/wrapper around Windows Win32 APIs to tie them into the Ecore main-loop and event queue.

Ecore X

BSD 2-Clause license

This is a library to wrap/deal with Xlib make dealing with X11 less painful and less footwork as well as being glue to tie these into the Ecore main-loop and event queue.

Edje

BSD 2-Clause license (except the epp binary which is GPLv2)

This is a graphics event, input, theme, animation and theme abstraction library used to place many UI/UX elements into data files (called edj files) that define how to react to incoming events/signals, and define animation time lines, states, relative scalable layout and much much more. It comes with a compiler that compiles source "edc" files into "edj" files (which are actually just data files managed by Eet). These "edj" files are fully portable and can work on any OS/Architecture just like a JPEG or PNG might be portable.

Eet

BSD 2-Clause license

This library is a data storage, encoding and decoding library designed to be extremely compact, fast and easy to use. It can take data structures directly from memory and serialize them portably to disk, then de-serialize them right back to the same data structures in memory, handling allocation and population of memory all for you in 1 call. It handles indirections such as pointers, linked lists, arrays and hash tables too, so almost any level of data structure complexity can be easily saved and loaded back. It is used for "edj" files by Edje as well as all configuration in Enlightenment, Elementary and Terminology. It supports encryption of data too via SSL, signing of files, as well as various compression techniques. It also supports encoding and decoding of image data in lossless or lossy form.

Eeze

BSD 2-Clause license

This library acts as an abstraction to discovering hardware interfaces for sensors as well as removable media and much more.

EFL

BSD 2-Clause license

This is just some core common header data like a common version number for EFL and how to expose the EO API.

Efreet

BSD 2-Clause license

This library provides code for handling Freedesktop.org standards such as .desktop files, XDG Menus, Icon search paths and more. It provides a central daemon to handle monitoring for changes that the library talks to, and the daemon handles updating local cache files the library reads.

Eina

LGPL v2 license

This library provides low-level routines for common things like linked lists, hash tables, growable arrays, basic string buffers, shared string tokens, mmaped() file access, thread abstraction and locking, memory pools, copy-on-write segments, iterators, matrices, general data models, red/black trees, quad-trees, a simple SAX XML parser and more.

EIO

LGPL v2 license

This is an asynchronous I/O library for doing disk I/O without blocking.

ElDBus

LGPL v2 license

This is a DBus access library to allow you to create DBus services as well as clients. This glues in DBus into the main-loop so all access is asynchronous.

Embryo

Small license (same as ZLib license)

This is a small C-like language compiler and byte-code interpreter library. This is used for scripting in Edje. The code is based on original source from the Pawn/Small Language but has been made portable (endianness issues fixed) and 64bit issues fixed, with the runtime library being refactored to be extremely small.

Emotion

BSD 2-Clause license

This is a wrapper around Gstreamer 1.x pluggable decoder libraries This glues in the decoder library, and its output into a smart Evas object that will display the playback for you as the video plays, as well as providing higher level controls to seek, play, pause and query the stream regardless of the back-end used.

EO

BSD 2-Clause license

This is a core object system API that EFL 1.8 and on depend on. The API is not finalized, so do not depend on it yet in EFL 1.8, but future EFL versions will lock it down.

This object system does simple and multiple inheritance, refcounting, strong and weak references, auto-deletion of child objects, unifies callback handling with a single path, and also abstracts object pointers to be indirect table lookups for increased safety at runtime.

EPhysics

BSD 2-Clause license

This library provides a wrapper around the Bullet physics library, allowing for it to be linked directly with Evas objects and control their behavior as if they were real physical objects. This is now disabled by default as it's rarely if ever used by anything.

Ethumb

LGPL v2 license

This library provides core API for a thumbnailing daemon as well as the thumbnail daemon itself. Ethumb Client talks with Ethumb to pass off thumbnail generation to a central location to be done asynchronously.

Ethumb Client

LGPL v2 license

This is the client-side part of Ethumb that provides an API for clients to request the Ethumb thumbnailer to generate or find cached thumbnails of files.

Evas

BSD 2-Clause license

This is the core rendering and scene graph abstraction library for EFL. It manages a stateful 2D scene graph that defines the entire content of any canvas. This supplies rendering back-ends for many display systems like X11, Windows, Wayland, Frame-buffer etc. and via many rendering APIs like OpenGL, OpenGL-ES 2, and pure software implementations that are fast and accurate.

Evil

BSD 2-Clause license

This library acts as a porting library for Windows to provide missing libc calls not in Mingw32 that EFL needs. It is used internally and no symbol is public.
