Koskript

Koskript is a simple, embeddable, and lightweight scripting language for Python applications. It features dynamic typing, lexical scoping, closures, classes and native Python interop — letting you expose any Python function or object directly to your scripts.

from koskript import KoskriptRuntime

runtime = KoskriptRuntime()
runtime.execute("""
const names = ["Ana", "Luis"]
array.each(names, (name) { print("hello " + name) })
""")

NOTE: Koskript is in early development. Module imports, error handling and performance improvements are on the way; expect the language and API to change between releases.

Features

• Dynamic typing.
• Block-level lexical scoping with local declarations.
• Closures that capture their defining scope, including this inside methods.
• Constants with const.
• Classes with inheritance, visibility, static methods and constructors.
• Standard library: core builtins plus map, array, string, math and json.
• Native Python interop for functions, objects and classes.
• if, elseif, else.
• while, for, foreach loops with break / continue.
• Member access and index access.
• First-class functions and lambda expressions.
• Arithmetic, comparison and logical operators.
• Embeddable in any Python application.
