Seed7
Interpreter and compiler for the Seed7 programming language.
Interpreter, compiler, libraries, documentation and examples for the Seed7 programming language. Seed7 is a general purpose programming language. It is a higher level language compared to Ada, C/C++ and Java. In Seed7 new statements and operators can be declared easily. Functions with type results and type parameters are more elegant than a template or generics concept. Object orientation is used where it brings advantages and not in places where other solutions are more obvious. Seed7 spares no effort to support portable programming. Several driver libraries assure that the access to operating system resources such as files, directories, network, clock, keyboard, console and graphics are done in a portable way. Although Seed7 contains several concepts from other programming languages, it is generally not considered a direct descendant of any other programming language. -

Go
Go (Golang): An open-source programming language supported by Google
Go (Golang) is an open-source programming language designed for simplicity, reliability, and efficiency. Created by Google, it is well-suited for building scalable software, from small utilities to large distributed systems. Go features a clean syntax, strong typing, and built-in concurrency support through goroutines, making it ideal for modern multi-core processors. The language comes with a powerful standard library and tools for testing, formatting, and package management, streamlining development workflows. Go’s compiler produces fast, statically linked binaries with minimal dependencies, ensuring portability and performance. Backed by a large, active community, Go continues to evolve with regular updates and extensive documentation. -

Repl.it
Online REPL for 15+ languages
This repository preserves an early open-source snapshot of the service that became Replit, a platform for writing and running code directly in the browser. The project’s core idea is instant, zero-setup programming: open a page, pick a language, type, and run—no local installs or environment wrangling. It combines an in-browser editor with a runnable backend or sandbox so code can execute safely and return output in seconds. Sharing and collaboration are first-class: code can be saved, forked, and embedded, which makes it useful for tutorials, classrooms, and quick demos. The architecture leans on simple web technologies so the learning curve stays low for educators and new programmers. Even as the commercial product evolved, this archive shows the foundational approach to making coding accessible anywhere with just a link. -

Starlark in Go
Starlark in Go: the Starlark configuration language, implemented in Go
starlark-go is the official Go implementation of the Starlark programming language, a Python-like, dynamically typed configuration and scripting language originally developed for the Bazel build system. Starlark combines Python’s expressiveness and readability with deterministic execution, making it ideal for defining build configurations, scripting automation, and embedding domain-specific logic in applications. The Go-based interpreter allows developers to run or embed Starlark programs directly within Go applications, extending them with user-defined scripts and configurable logic. Unlike Python, Starlark supports parallel execution across multiple threads and maintains deterministic behavior, making it suitable for scalable and reproducible workloads. It offers familiar syntax features such as dictionaries, lists, and first-class functions with lexical scoping. -

Mangle
Go library for Datalog-style logical reasoning and domain modeling
Mangle is a programming language developed by Google for deductive database programming, serving as an advanced extension of Datalog. It is designed to unify and query data from multiple sources in a structured, declarative way while allowing developers to model complex relationships and domain knowledge beyond binary predicates. Mangle enhances traditional Datalog by introducing features such as aggregation, function calls, and optional type-checking, which make it more practical for modern data-intensive applications. Unlike SQL, Mangle’s declarative syntax naturally supports recursion and modular program structure, making it suitable for representing hierarchical or interconnected datasets like dependency graphs or knowledge graphs. The project’s implementation is provided as a Go library, enabling developers to embed Mangle directly into their applications or services, such as database-like gRPC systems. -

Ficl is a lightweight, embeddable scripting language designed to be incorporated into other programs, and especially embedded systems that may have memory and OS constraints. Applications include scripting, hardware bring-up, rapid prototyping, and system extensions. Unlike Lua or Python, Ficl acts as a component of your system - you feed it stuff to do, it does the stuff, and comes back to you for more. You can export compiled code to Ficl, execute Ficl code from your compiled code, or interact. Your choice.

NetRexx
The open sourced NetRexx reference implementation
NetRexx is a dialect of the REXX programming language to run on the Java virtual machine. It supports a classic REXX syntax, with no reserved keywords, along with considerable additions to support object-oriented programming in a manner compatible with Java's object model, yet can be used as both a compiled and an interpreted language, with an option of using only data types native to the JVM or the NetRexx runtime package. Originally from IBM, NetRexx is the creation of Mike Cowlishaw, the 'Father of Rexx'. This IBM product has been open sourced in 2011. -

SPL Compiler
A low-level system programming language with high-level syntax
A new system programming language designed to occupy the same niche C is currently holding, that allows for easier development of large platform-independent systems. The aims are to: * Keep all of C's system programming strengths. * Be as efficient as C (at run-time) and as high-level as possible for the programmer. * Promote modularity and ease the development of large-scale component-based software. * Enable programming-by-contract and other high-level features (as long as they incur no extraordinary costs at run-time). * Provide a stricter and more platform-independent type system than C. * Allow direct use of existing C and platform (e.g. Win32 API) libraries. This phrase from the "SPL Language Reference" says it all: "One could say SPL is what C should have been, were it not for the limitations of the time when C was designed". -
