Cala is intended to be an "oxidized re-implementation" of both Flutter/GTK and SDL/other SDL projects in one library! Flutter is mostly intended for mobile applications, and GTK is just for desktop applications, but what if you want to develop the same app for both? Then you use this crate (a lot of features are still WIP)! Cala additionally targets the web and bare metal systems. Note also that even if you're not trying to make your application / video game extremely portable, you can still use this crate!
You might ask, "Shouldn't apps and video games use separate libararies; Why are
they combined?". They usually need do the same thing, and some desktop
application depend on SDL, like VLC, and some
video games depend on GTK, like Veloren (at least when
built on Linux). There's clearly a shared interest; so they should be
combined. That said, Cala is extremely modular, and doesn't include any modules
at all unless you enable some features. The modules are named exactly the same
as the features, so you enable the audio feature to be able to use the audio
module.
The name cala is derived from the fungus known as calafate rust.
Here's a list of all of the targeted platforms and what they support. "X" means it's supported, "-" means it's not planned. "?" means it might work, but hasn't been tested yet. Some planned features have associated issues linked with the number.
| Feature | Linux | MacOS | Windows | Web | Android | |------------|-------|-------|---------|-----|---------| | accel | | | | | | | bluetooth | | | | | | | camera | | | | | | | draw | X |9 | 8 | | | | exec | X | | | X | | | file | X | X | X | | | | gpio | | - | - | - | | | input | X |7 | 6 | ? | | | journal | X | X | X | X | | | microphone | X |5 | 4 | X | ? | | net | X | X | X | ? | | | pixels | X |9 | | | | | speaker | X | | 4 | X | ? | | time | X | X | X | X | | | user | X | X | X | X | |
Each hardware interface can be enabled with a feature. For example, If you
want to depend on the audio feature and the clock
feature, you might put this in your Cargo.toml:
toml
[dependencies.cala]
version = "0.8"
features = ["audio", "clock"]
There is a module for each feature (feature and module names match). Module documentation may include simple tutorials. More in depth tutorials may be found here.
Here's a list of the features, with links to documentation.
user - Getting user informationaudio - Playing / recording audioclock - Date, Time of day, Timergamepad - Game Controller - JoyStickfiles - Containerized filesystem loading / saving ZIP filesdraw - Render and User InterfaceContributors are always welcome! Whether it is a bug report, bug fix, feature request, feature implementation or whatever. Don't be shy about getting involved. I always make time to fix bugs, so usually a patched version of the library will be out soon after a report. Features take me longer, though. I'll also always listen to any design critiques you have. If you have any questions you can email me at jeronlau@plopgrizzly.com. Otherwise, here's a link to the issues on GitHub.
And, as always, make sure to always follow the code of conduct. Happy coding!
