About:
Mruby is a lightweight implementation of the Ruby language, designed for embedding within applications and resource-constrained environments. Unlike standard Ruby, it can be compiled into a single static library, allowing developers to add scripting capabilities to C/C++ projects without heavy dependencies. Its modular architecture enables the inclusion of only necessary features, optimizing for performance and minimal memory footprint.

Key Features:

Embeddable and linkable into C/C++ applications
Compiles to a single static library
Highly configurable and modular core
Supports bytecode compilation for efficiency

Use Cases:

Scripting for embedded systems and IoT devices
Adding extensibility to C/C++ applications
Creating domain-specific languages (DSLs)

Alternatives:

CRuby – The standard, full-featured Ruby interpreter; much larger footprint but with complete standard library support.
Lua – A popular, lightweight scripting language often used for embedding; generally smaller and faster than Mruby.
