About:
Chibi-Scheme is a minimalist Scheme implementation designed for embedding in C applications. It provides a lightweight, full-featured R7RS-small compliant interpreter with a small memory footprint. Its primary value is enabling scripting capabilities in resource-constrained environments or C-based projects.
Key Features:
  • R7RS-small standard compliance
  • Extremely small memory footprint (~100KB)
  • Seamless C API for embedding
  • Support for native threads
  • Extensible via C modules
Use Cases:
  • Embedding scripting into C/C++ applications
  • Configuration and automation in embedded systems
  • Teaching programming language implementation
  • Plugin systems for performance-critical software
Alternatives:
  • Guile – Larger and more feature-rich, but significantly heavier footprint
  • TinyScheme – Similar minimalist goals, but Chibi offers better standards compliance
  • Lua – More popular for embedding, but uses different programming paradigm
