Mochi is a statically typed, embeddable programming language designed for agents, data processing, and AI applications. It offers a declarative, functional syntax with stream-first semantics, aiming for clarity, safety, and expressiveness.

How It Works

Mochi compiles to optimized bytecode executed by a built-in virtual machine. Its design emphasizes agent-friendliness, testability with built-in test blocks, and portability as a single, zero-dependency binary. It features native support for datasets with SQL-like querying, graph manipulation, and simulation capabilities, alongside direct integration with generative AI models.

Quick Start & Requirements

• Installation: Download the prebuilt binary from releases, make it executable (chmod +x mochi), and run with mochi run examples/hello.mochi. Docker is also supported: docker run -i --rm ghcr.io/mochilang/mochi run examples/hello.mochi.
• Prerequisites: Docker is required for containerized execution. Local LLMs (e.g., via llama.cpp) may be needed for VS Code Agent Mode integration.
• Resources: Setup is minimal for the native binary.
• Links: Releases, VS Code Extension, MCP Server Config

Highlighted Details

• Built-in support for generative AI, including generate blocks for text and structured data, and exposing Mochi functions as LLM tools.
• SQL-like dataset querying with from, where, select, and various join types.
• Stream processing capabilities with stream, on, and emit for event-driven architectures.
• MCP (Multi-Agent Communication Protocol) compatibility for integration with tools like Claude Desktop and VS Code Agent Mode.

Maintenance & Community

The project is actively developed. Community interaction channels are not explicitly listed in the README.

Licensing & Compatibility

Mochi is released under the MIT License, permitting commercial use and integration with closed-source projects.

Limitations & Caveats

Mochi is under active development, with several features not yet implemented across all backends, including error handling (try/catch), logic programming, set collections, generic type parameters, reflection, concurrency primitives, asynchronous functions, and certain advanced language constructs like destructuring bindings and closures.
