PrSM (Pragmatic Reduced Syntax for Metascript) is a Unity-first scripting language toolkit.
It compiles .prsm scripts to readable C# with syntax sugar for components, coroutines,
event listeners, input handling, interfaces, generics, singleton, object pooling,
pattern matching, async/await, state machines, and reactive bindings.
Language 5 adds general yield, attribute targets, preprocessor directives, ref/out/vararg
parameters, nameof, advanced patterns (relational/combinator/positional/property),
with expressions, ref locals, partial declarations, and a DAP debugger adapter.
Includes VS Code extension and Unity Editor package.
