Chili
A programming language for data analysis and engineering, written in Rust.
Chili uses Polars for data manipulation and Arrow/Parquet for data storage.
Language Syntaxes
Chili provides two language syntaxes:
- chili — a modern syntax similar to JavaScript.
- pepper — a vintage syntax similar to q.
Features
- Polars-powered — full Polars DataFrame support for high-performance data manipulation
- Arrow / Parquet storage — native support for columnar data formats
- Partitioned tables — date-partitioned Parquet storage with partition pruning
- Lazy evaluation — lazy DataFrames with
collectfor deferred computation - IPC / TCP — built-in TCP listener for remote connections
- Tick / Sub — publish-subscribe infrastructure for real-time data
- Job scheduler — periodic job execution and memory monitoring
- Cross-platform — Linux, macOS, and Windows
Installation
Via pip (recommended)
pip install chili-pie
From source
cargo build --release --bin chili
Python bindings (chili-sauce)
pip install chili-sauce
Quick Start
Launch the REPL:
# chili syntax (default)
chili
# pepper syntax
chili -P
Evaluate a script:
chili script.chi
Architecture
crates/
├── chili-bin # CLI binary & REPL
├── chili-core # Engine state, evaluator, IPC, and built-in functions
