Scenic is a client application library written directly on the Elixir/Erlang/OTP stack. With it you can build applications that operate identically across all supported operating systems, including MacOS, Ubuntu, Nerves/Linux, and more.
Scenic is primarily aimed at fixed screen connected devices (IoT), but can also be used to build portable applications.
See the documentation for the scenic.new mix task.
-
Available: Scenic takes full advantage of OTP supervision trees to create applications that are fault-tolerant, self-healing, and highly available under adverse conditions.
-
Small and Fast: The only core dependencies are Erlang/OTP and OpenGL.
-
Self Contained: “Never trust a device if you don’t know where it keeps its brain.” The logic to run a device should be on the device and it should remain operational even if the service it talks to becomes unavailable.
-
Maintainable: Each device knows how to run itself. This lets teams focus on new products and only updating the old ones as the business needs.
-
Remotable: Scenic devices know how to run themselves, but can still be accessed remotely. Remote traffic attempts to be as small so it can be used over the Internet, cellular modems, Bluetooth, etc.
-
Reusable: Collections of UI can be packaged up for reuse with, and across applications. I expect to see Hex packages of controls, graphs, and more available for Scenic applications.
-
Flexible: Scenic uses matrices similar to game development to position everything. This makes reuse, scale, positioning and more very flexible and simple.
-
Secure: Scenic is designed with an eye towards security. For now, the main effort is to keep it simple. No browser, Javascript, and other complexity presenting vulnerabilities. There will be much more to say about security later.
-
Browser: Scenic is not a web browser. It is aimed at a fixed screen devices and certain types of windowed apps. It knows nothing about HTML.
-
3D: Scenic is a 2D UI framework. It uses techniques from game development (such as transform matrices), but it does not support 3D drawing at this time.
-
Immediate Mode: In graphics speak, Scenic is a retained mode system. If you need immediate mode, then Scenic isn’t for you. If you don’t know what retained and immediate modes are, then you are probably just fine. For reference: HTML is a retained mode model.
We appreciate any contribution to Scenic.
However, please understand that Scenic is still fairly new and as such, we'll be keeping an extra-close eye on changes.
Check the Code of Conduct and Contributing Guides for more information. We usually keep a list of features and bugs in the issue tracker.
The easiest way to contribute is to help fill out the documentation. Please see the Contributing Guides first.
