Lux
The Lux Programming Language
Lux is a new programming language in the making. It's meant to be a functional, statically-typed Lisp that will run on several platforms, such as the Java Virtual Machine and JavaScript, Python, Lua, or Ruby interpreters. Lux is in the beta stage. The JVM compiler is pretty stable and the standard library has grown to a respectable size. Also, new experimental support for JavaScript, Python, Lua, and Ruby has been added. Read carefully before using this project, as the license disallows commercial use, and has other conditions which may be undesirable for some. The language is mostly inspired by the following 3 languages. Clojure (syntax, overall look & feel), Haskell (functional programming), and Standard ML (module system). They are implemented as plain-old data-structures whose expressions get eval'ed by the compiler and integrated into the type-checker. The main difference between Lux & Standard ML is that Standard ML separates interfaces/signatures and implementations/structures. -

MoonScript
A language that compiles to Lua
MoonScript is a dynamic scripting language that compiles into Lua. It gives you the power of one of the fastest scripting languages combined with a rich set of features. MoonScript can either be compiled into Lua and run at a later time, or it can be dynamically compiled and run using the moonloader. It’s as simple as requiring "moonscript" in order to have Lua understand how to load and run any MoonScript file. Because it compiles right into Lua code, it is completely compatible with alternative Lua implementations like LuaJIT, and it is also compatible with all existing Lua code and libraries. The command line tools also let you run MoonScript directly from the command line, like any first-class scripting language. -

Pkl
A configuration as code language with rich validation and tooling
pkl is a purpose-built configuration-as-code language developed by Apple that combines declarative structure, validation, and tooling to improve over traditional configuration formats like JSON, YAML, or Plists. Its goal is to let you write configuration logic (modules, imports, conditions, defaults) while still producing static outputs suitable for tools that expect JSON, YAML, or other formats. Configurations in Pkl are type-safe and support validation constraints (e.g. bounds, relations) so many errors can be caught before deployment. The language is embeddable, meaning it can run inside applications (Java, Swift, Go, etc.) to load configuration dynamically with the same safety guarantees. There’s also code generation support: writing Pkl modules can generate matching classes or data structures in target languages (Swift, Go, Java, Kotlin) so runtime config and statically typed code stay in sync. -

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. -

stylus
Expressive, robust, feature-rich CSS language built for nodejs
Stylus is a revolutionary new language, providing an efficient, dynamic, and expressive way to generate CSS. Supporting both an indented syntax and regular CSS style. Installing Stylus is very easy once you have Node.js. So get the binaries for your platform and make sure that they also include npm, Node’s package manager. Stylus features powerful in-language function definitions. Function definitions appear identical to mixins; however, functions may return a value. Optional arguments may default to a given expression. With Stylus we may even default arguments to earlier arguments! Stylus is an innovative stylesheet language that compiles down to CSS. Inspired by SASS, Stylus is built with node.js and capable of running in the browser. Stylus is “pythonic” (i.e. indentation-based). Whitespace is significant, so we substitute { and } with an indent, and an outdent. Stylus, just like CSS, allows you to define properties for several selectors at once through comma separation. -

Hy
A dialect of Lisp that's embedded in Python
Hy is a multi-paradigm general-purpose programming language in the Lisp family. It’s implemented as a kind of alternative syntax for Python. Compared to Python, Hy offers a variety of extra features, generalizations, and syntactic simplifications, as would be expected of a Lisp. Compared to other Lisps, Hy provides direct access to Python’s built-ins and third-party Python libraries, while allowing you to freely mix imperative, functional, and object-oriented styles of programming. The first thing a Python programmer will notice about Hy is that it has Lisp’s traditional parenthesis-heavy prefix syntax in place of Python’s C-like infix syntax. As in other Lisps, the value of a simplistic syntax is that it facilitates Lisp’s signature feature, metaprogramming through macros, which are functions that manipulate code objects at compile-time to produce new code objects, which are then executed as if they had been part of the original code. -

Mint
A refreshing programming language for the front-end web
Mint has all the tools you need to write error-free, easily readable, and maintainable applications in record time. In Mint you can style elements directly with CSS using style blocks. Inside a style block, you can nest as many sub selectors and media queries as you like. Interpolate any Mint expressions in any value using the interpolation syntax. You can even use if and case expressions inside any block to apply styles conditionally. In Mint a store contains and manages some data. Stores are globally accessible and can be connected to components. When the data in a store changes the connected components are re-rendered. In Mint routing is a language feature instead of a library. Routes can be defined in a routes block, with support for typed path parameters. The runtime handles clicks on anchor tags and navigates in a smart way so you don't have to. You can inline any JavaScript code easily by using bacticks. -

Skylark
Skylark in Go: the Skylark configuration language
Skylark, now known as Starlark, is an interpreter for a Python-like language implemented in Go. It is designed as a lightweight, deterministic, and embeddable configuration and scripting language ideal for use within larger applications. Skylark maintains Python’s familiar syntax and high-level data types while omitting features that could cause nondeterminism, such as concurrency and dynamic module imports. The interpreter supports first-class functions, dictionaries, lists, and comprehensions, allowing developers to define reusable logic and structured configuration data. Originally developed for Bazel, Google’s build tool, Skylark enables users to define build rules and macros that extend system functionality. Because it runs deterministically and isolates execution from system state, it’s well-suited for reproducible build systems and other sandboxed environments. The Go implementation focuses on parallel scalability and easy integration into Go-based projects. -

SpinalHDL
Scala based HDL
SpinalHDL is a hardware description (HDL) framework embedded in Scala, enabling hardware designers to build digital circuits with modern programming abstractions. Instead of writing in Verilog or VHDL directly, users describe hardware components and their interconnects using Scala code and Spinal’s domain-specific library, which then emits synthesizable hardware (e.g. as Verilog). Because SpinalHDL is embedded in Scala, it allows reuse of functional abstractions, parameterization, modular composition, and higher-level constructs to manage complexity. It supports building systems at various levels—single modules, pipelines, memories, controllers, etc.—while letting the designer control timing, pipelining, and resource sharing explicitly. The generated hardware can be synthesized for FPGAs or ASIC flows, making it practical for real designs. -
13
Tidal
Pattern language
Tidal Cycles (or just Tidal for short) is software for making patterns with code, whether live coding music at algoraves or composing in the studio. It includes a simple and flexible notation for rhythmic sequences and an extensive library of patterning functions for combining and transforming them. This allows you to quickly create complex patterns from simple ingredients. By default, sound is made with the featureful SuperDirt synth/sampler, but you can control other synths using Open Sound Control (OSC) or MIDI. Whether you're using SuperDirt or a synth, every filter and effect can be manipulated independently with Tidal patterns. Tidal is embedded in the Haskell language, although you don't have to learn Haskell to learn Tidal. You can learn Tidal through experimentation and play, most Tidal coders have little or no experience in software engineering. -

Unison
A friendly programming language from the future
Unison is an open source functional programming language based on a simple idea with big implications: code is content-addressed and immutable. Unison’s core idea is that code is immutable and identified by its content. This lets us reimagine many aspects of how a programming language works. We simplify codebase management, Unison has no builds, no dependency conflicts, and renaming things is trivial. The same core idea forms the basis for a runtime that robustly supports dynamic code deployment, allowing a single Unison program to describe entire elastic distributed systems. Though a lot of the work on Unison is still experimental and ongoing, we’re sharing an early alpha release of the language for you to test out. We’ll make a more finished release generally available soon. In the meantime, anyone is welcome to help with alpha testing. -

Autocxx
Tool for safe ergonomic Rust/C++ interop driven from existing C++
autocxx is an open source Rust tool and procedural macro designed to enable automatic, safe interoperability between C++ and Rust. It integrates the functionality of bindgen (for parsing and generating Rust bindings from C++ headers) with cxx (for safe and idiomatic Rust–C++ communication), automating the creation of bridges between the two languages. With autocxx, developers can include C++ headers directly in Rust source code and automatically generate bindings for the corresponding C++ classes, functions, and types. This approach greatly simplifies working with existing C++ libraries in Rust while maintaining safety and memory correctness. By reducing the amount of boilerplate and manual configuration typically needed for FFI (Foreign Function Interface) bindings, autocxx allows developers to focus on higher-level logic rather than low-level integration details. -

Chez Scheme
A programming language and an implementation of that language
Chez Scheme is both a programming language and an implementation of that language, with supporting tools and documentation. As a superset of the language described in the Revised6 Report on the Algorithmic Language Scheme (R6RS), Chez Scheme supports all standard features of Scheme, including first-class procedures, proper treatment of tail calls, continuations, user-defined records, libraries, exceptions, and hygienic macro expansion. The Chez Scheme implementation consists of a compiler, run-time system, and programming environment. Although an interpreter is available, all code is compiled by default. Source code is compiled on-the-fly when loaded from a source file or entered via the shell. A source file can also be precompiled into a stored binary form and automatically recompiled when its dependencies change. Whether compiling on the fly or precompiling, the compiler produces optimized machine code, with some optimization across separately compiled library boundaries. -
