🐈 The Charly Programming Language | Written by @KCreate

ChezScheme is a compiler and runtime environment for the Scheme programming language that transforms source code into optimized machine binaries. It serves as a high-performance implementation of the language, producing executable machine code for execution on physical hardware. The project features a native machine code compiler, a read-eval-print loop for executing and editing multi-line expressions in real time via a shell, and a generational garbage collected runtime for automatic memory management. It also includes a foreign function interface for integrating external C libraries and lan

A statically typed scripting language that transpile into POSIX sh

CUE has moved to https://github.com/cue-lang/cue

Tengo is a dynamic, embeddable scripting language for Go applications that allows for the execution of custom scripts without requiring the host binary to be recompiled. It operates as a bytecode-compiled virtual machine, transforming source code into a compact intermediate representation for execution on a stack-based engine. The system is designed as a secure scripting sandbox, enforcing strict limits on memory allocation and execution time to safely run untrusted code. It supports concurrent script execution by cloning compiled bytecode and using recursive immutability conversion to share

Decorated Syntax Tree - manipulate Go source with perfect fidelity.

PHP bindings for the Go programming language (Golang)

Goja is a JavaScript engine and ECMAScript compliant interpreter implemented entirely in Go. It serves as an embedded scripting engine that allows Go applications to execute JavaScript code and integrate a programmable scripting layer without relying on Cgo or external native dependencies. The project functions as a bridge between Go and JavaScript, enabling bidirectional data exchange and function invocation. It allows Go hosts to expose native structs, slices, and maps as JavaScript objects and arrays, while providing mechanisms to export script values and functions back into native Go type

CoreCLR is a runtime environment that manages the execution, memory, and basic types for applications built on the .NET platform. It serves as a managed execution environment that handles low-level system interactions and provides primitive data types for high-level application code. The project functions as a JIT compilation engine and a garbage collected runtime. It translates intermediate language into machine code at runtime for execution on specific hardware and automatically reclaims unused memory to prevent leaks. The system covers broad capability areas including managed code executi

The .NET Compiler Platform is a collection of open-source APIs for C# and Visual Basic that provides deep code analysis, refactoring, and automated source code generation. It serves as the core infrastructure for building development tools, offering a platform to inspect, modify, and understand source code through immutable syntax trees and semantic models. The platform distinguishes itself by providing full-fidelity syntax trees that preserve every character of source code, including whitespace and comments, alongside an incremental compilation pipeline that enables near-instant feedback dur

ELENA is a general-purpose language with late binding. It is multi-paradigm, combining features of functional and object-oriented programming. Rich set of tools are provided to deal with message dispatching : multi-methods, message qualifying, generic message handlers, run-time interfaces

Elvish is a shell that combines interactive command-line use with a structured scripting language, designed to make both everyday terminal work and automation tasks more predictable and readable. It parses, compiles, and executes code in three phases, catching syntax and variable errors before any code runs, and it aborts execution on command failure by default to prevent silent errors. The shell introduces value-oriented pipelines that pass structured data like lists, maps, and closures between commands, preserving types without serialization. It also mixes traditional byte streams with thes

Easy Programming Language / VM

OTP is a concurrent programming framework and distributed computing platform that serves as the Erlang runtime environment. It provides a fault-tolerant operating environment designed for building scalable, real-time systems that manage massive amounts of simultaneous tasks through asynchronous messaging. The environment is distinguished by its use of an actor-based concurrency model and hierarchical supervision trees that automatically restart failed processes. It supports hot code loading to allow system updates without downtime and utilizes a preemptive user-space scheduler to manage light

The Eschelle programming language

HHVM is a high-performance execution engine and runtime environment designed for the Hack language. It functions as a persistent web application server that processes incoming network traffic, while also providing command-line utilities for executing standalone scripts and performing automated tasks. The project distinguishes itself through a sophisticated execution model that utilizes just-in-time compilation to translate bytecode into optimized machine code. This process is supported by a static type analysis engine that enforces strict data constraints and identifies type inconsistencies b
