Interactive REPL
Run kria with no arguments. Persistent session, multi-line input, and command history.
Kria Programming Language
A dynamic, strongly typed language with a flat bytecode VM and combined loop
instructions for high-performance execution. Write .krx files or use the
interactive REPL.
How it works
Source
Lexer
Parser
Compiler
VM
Kria compiles source into flat bytecode with a constant pool, then runs it on a stack-based VM with call frames for functions and closures.
Features
Functions & Closures
Named functions, lambdas, and nested closures with copy-on-create capture semantics.
Arrays & Objects
Mutable and immutable arrays, object literals, deep equality, and for-in iteration.
Modules
Multi-file projects with export fn and import alias from "./file.krx".
Performance
Combined loop opcodes like OP_LOOP_INC_LESS reduce hot-path dispatch overhead.
Dynamic Typing
Strong, dynamic types with null for undefined variables. Newline-based statements, no semicolons.
Quick example
fn greet(name) {
return "Hello, " + name
}
set message = greet("Kria")
print(message)
