ProtoFlo

Experiments in dataflow and Flow-based programming based on Python, compatible and integrated with NoFlo

Installing

After having Python 2.7 installed, from the clone:

git clone https://github.com/chadrik/protoflo
cd protoflo
sudo pip install -r requirements.txt

Running

cd into the directory that you cloned ProtoFlo into.
Register ProtoFlo as a NoFlo runtime (discover what is your UID on NoFlo)
```
python -m protoflo register --user YOUR_UID --label ProtoFlo
```
Start the ProtoFlo runtime.
```
python -m protoflo runtime
```
Create a new project in NoFlo selecting the ProtoFlo runtime
Inside the new project/graph, select the appropriate ProtoFlo runtime clicking on the top-right menu
Green arrows should appear on the top-right menu, right before ws:\\localhost:3569
Try typing Add into the component search box on top-left

Testing

First install the test suite:

nmp install -g fbp-protocol

Then, from the repo directory, run the tests

fbp-test

Components

Modules with names beginning with "protoflo" on the Python Path are searched for components - they must have a __components__ attribute which is a dict listing the components. Components should be sub-classes of protoflo.components.IComponent or methods which return IComponent objects. Alternatively, they can be a filename pointing to a json or fbp graph file.

Status

Prototyping

Can create and run graphs using the NoFlo UI protocol.
