# Epsilon
[](https://github.com/jbouwman/epsilon/actions/workflows/ci.yml)
[](https://jbouwman.github.io/epsilon/)
Epsilon is a Lisp programming environment built on top of SBCL that provides functional data structures, data encoding, cryptographic functionality, and network programming capabilities.
## Features
- **Functional Data Structures** - Immutable maps, sets, and sequences with structural sharing
- **Data Encoding** - JSON, YAML, MessagePack, Base64, and binary format support
- **Cryptography** - SHA-2 family hashing, CRC-32, and Adler-32 checksums
- **Network Programming** - HTTP client/server with TLS support
- **Development Tools** - Build system, test framework, and benchmarking utilities
- **Few Dependencies** - Depends only upon SBCL built-in modules
## Installation
### Quick Install
Install Epsilon runtime:
```bash
curl -sSL https://raw.githubusercontent.com/jbouwman/epsilon/main/scripts/install.sh | bash
```
This installs a complete SBCL runtime with Epsilon preloaded.
### Manual Installation
Download the appropriate release for your platform from [GitHub Releases](https://github.com/jbouwman/epsilon/releases):
- `epsilon-macos-arm64.tar.gz` - macOS Apple Silicon
- `epsilon-macos-x86_64.tar.gz` - macOS Intel
- `epsilon-linux-x86_64.tar.gz` - Linux x86_64
- `epsilon-windows-x86_64.zip` - Windows x86_64
### Usage
#### Unix (Linux/macOS)
```bash
# Interactive REPL with Epsilon loaded
epsilon
# Evaluate expressions
epsilon --eval "(format t \"Hello, Epsilon!\")" --eval "(sb-ext:quit)"
# Use Epsilon libraries
epsilon --eval "(epsilon.lib.map:make-map :a 1 :b 2)" --eval "(sb-ext:quit)"
```
#### Windows
```powershell
# Interactive REPL with Epsilon loaded
.\epsilon.exe
# Evaluate expressions
.\epsilon.exe --eval "(format t \"Hello, Epsilon!\")" --eval "(sb-ext:quit)"
# Use Epsilon libraries
.\epsilon.exe --eval "(epsilon.lib.map:make-map :a 1 :b 2)" --eval "(sb-ext:quit)"
```
