## What it is
Umka is a statically typed, embeddable scripting language implemented in C99, with a bytecode compiler and virtual machine distributed as a static or dynamic library with a simple C API. It offers Go-inspired syntax, compile-time type checking, garbage collection, C-compatible arrays and structs, interfaces, and fiber-based multitasking.

## Use cases
- embed a scripting language in a C or C++ application
- add a statically typed scripting layer to a game engine
- script configuration or logic with compile-time type checking
- run lightweight coroutines or fibers for multitasking
- learn or experiment with language and VM implementation
- prototype algorithms in a simple Go-like scripting language

## When to choose
- you need an easily embeddable scripting language with a clean C API
- you want static typing in a scripting language
- you need C-compatible data structures passed between host and scripts
- you want fiber-based cooperative multitasking in scripts

## When to avoid
- you need a mature ecosystem with extensive third-party libraries
- you require maximum raw performance from compiled native code
- you need dynamic typing or metaprogramming-heavy scripting
- you need broad community support and long-term guarantees

## Facets
- artifact type: library
- maturity: active
- function: interpreter, compiler, programming-language, concurrency
- domain: programming-languages, developer-tools, cross-platform
- platform: cross-platform, c, cpp, windows, wasm
