Vyn — High-performance systems language

Philosophy: Native speed, hot reload, web + AI + DB built-in.

Install

pip install -r requirements.txt

Commands

python -m vyn.cli run examples/match_demo.vyn
python -m vyn.cli run examples/ai_train.vyn
python -m vyn.cli run examples/db_demo.vyn
python -m vynstudio.main

python -m vpm install          # install packages from vyn.toml
python -m vpm add db           # add SQLite package

Language features

Feature	Example
hot fn	Live reload without restart
@[profile]	Built-in profiling
enum	enum Color { Red, Green }
match/case	Pattern matching
try/catch/throw	Error handling
struct/impl	OOP-style methods
extern "C"	FFI to C
Ownership	mut, immutable by default

VPM Packages

Package	Purpose
serde	JSON serialize/deserialize
collections	Stack, Queue
neural	ReLU, sigmoid (hot-swap)
ai	Train & save neural networks
db	SQLite database
async	defer_ms, yield
web	HTML helpers

Standard library (31 modules)

Core: io, sys, math, str, fs, net, http, server, html, css, json, db, ai, gui, log

ML / Data Science (Python bindings):

Module	Python	Example
std.numpy	NumPy	numpy.array([1.0,2.0]); numpy.mean(data)
std.torch	PyTorch	torch.train_linear(50); torch.tensor(data)
std.tensorflow	TensorFlow	tensorflow.train_xor(100)
std.cv	OpenCV	cv.grayscale("in.png","out.png")
std.pandas	Pandas	pandas.read_csv("data.csv")
std.sklearn	scikit-learn	sklearn.fit_linear(xs, ys)
std.plot	Matplotlib	plot.line("chart.png", xs, ys, "title")

pip install numpy pandas scikit-learn matplotlib opencv-python
pip install torch tensorflow   # optional, large
python -m vyn.cli run examples/ml_bindings.vyn
