This October, I'm committing to committing to the FormaK project every day and writing a blog post about development and adjacent projects that I'm working on.
The FormaK Project¶
What is the FormaK project do you ask? The FormaK project aims to combine symbolic modeling for fast, efficient system modeling with code generation to create performant code that is easy to use.
A Simple Model¶
With a little simplification, a model that looks like this:
```python dt = Symbol("dt")
tp = trajectory_properties = {k: Symbol(k) for k in ["mass", "z", "v", "a"]}
thrust = Symbol("thrust")
state = set(tp.values())
control = set([thrust])
state_model = {
tp["mass"]: tp["mass"],
tp["z"]: tp["z"] + dt * tp["v"],
tp["v"]: tp["v"] + dt * tp["a"],
tp["a"]: -9.81 * tp["mass"] + thrust,
}
model = Model(dt=dt, state=state, control=control, state_model=state_model)
```
Useable C++¶
... becomes code you can use that looks like this:
generated/simple.h
c++
class StateModel {
State process(const State& state, const Control& control);
// implementation also generated
};
If you'd like to see examples that are beyond a toy example, check out the project demos.
30 for 30¶
My goal is to work on consistently contributing to the project and writing about it. To that end, I'm going to be writing and posting here once daily about what I'm working on and what I'm learning about to advance the project.
