Chili Sauce 🌶️

Python bindings for Chili's EngineState, powered by PyO3.

Installation

pip install chili-sauce

Requires Python ≥ 3.10.

Quick Start

from chili import ChiliEngine

engine = ChiliEngine()

# Evaluate expressions
engine.eval("1 + 2")  # => 3

# Variable management
engine.set_var("x", 42)
engine.get_var("x")  # => 42

# Work with Polars DataFrames
import polars as pl

df = pl.DataFrame({"a": [1, 2, 3], "b": [4, 5, 6]})
engine.set_var("df", df)
engine.get_var("df")

IPC / Remote Queries

# Open a handle to a remote Chili process
h = engine.open_handle("chili://:1800")

# Send synchronous queries
engine.sync(h, b"1+1")                # bytes  — sent as a raw string query
engine.sync(h, ["set", "a", 2])       # list   — sent as a function call (func, args…)

Features

Evaluate Chili or Pepper expressions from Python
Variable management — get, set, delete, and list variables
Polars integration — pass DataFrames bidirectionally between Python and Chili
Partitioned storage — write and load date-partitioned Parquet tables
IPC / TCP — start a TCP listener for remote connections
Tick plant — built-in pub/sub infrastructure for real-time data
