ZenFlo
Flow Based Programming Kit.
ZenFlo is an implementation of flow-based programming for Haxe running on and expected to run on all Haxe targets. It is a port of the NoFlo library.
Scope
ZenFlo is a way to coordinate and reorganize data flow in any application. If you are building no-code/low-code programs or editors, ZenFlo handles that. Each node is a black-box or small unit of your program, and ZenFlo helps you connect these nodes in such a way that they are portable and reusable.
Dependencies
This project uses lix.pm as Haxe package manager.
Run npm install to install the dependencies.
Run Tests
npx run haxe test.hxml
Usage
Read the NoFlo Documentation on how components are loaded.
To convert an Haxe function into a ZenFlo component:
import zenflo.lib.loader.ManifestLoader;
import zenflo.lib.Macros.asComponent;
import zenflo.lib.Macros.asCallback;
import zenflo.lib.Utils.deflate;
ManifestLoader.init();
final loader = new ComponentLoader(Sys.getCwd()));
final component = (_) -> asComponent(deflate(Math.random), {});
loader.registerComponent('math', 'random', component, (e) -> done());
loader.load('math.random').handle(cb -> {
switch cb {
case Success(_): {
final wrapped = asCallback('math.random', {loader: loader});
wrapped('bang', (err, res) -> {
if (err != null) return;
trace(Std.isOfType(res, Float)); // True
});
}
case Failure(err):{
// throw error
}
}
});See the Component Spec for more examples of how components send data to eachother.
