MicroPython
Python implementation for microcontrollers and constrained systems
MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimised to run on microcontrollers and in constrained environments. The MicroPython pyboard is a compact electronic circuit board that runs MicroPython on the bare metal, giving you a low-level Python operating system that can be used to control all kinds of electronic projects. MicroPython is packed full of advanced features such as an interactive prompt, arbitrary precision integers, closures, list comprehension, generators, exception handling and more. Yet it is compact enough to fit and run within just 256k of code space and 16k of RAM. MicroPython aims to be as compatible with normal Python as possible to allow you to transfer code with ease from the desktop to a microcontroller or embedded system. -

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. -

Crafting Interpreters
Repository for the book "Crafting Interpreters"
This repository is the companion to the book Crafting Interpreters. It contains the full source code for two interpreters (one in C and one in Java), the Markdown source of the book, the tooling to weave prose and code into a website, and build scripts to generate the executable interpreters. The book aims to teach from the ground up how to build a full-featured scripting language (called Lox) with parsing, AST, compiler / VM, garbage collection, classes, and more. Static site generator tooling to compose book + code into HTML. Markdown source of book chapters and text prose. Full interpreter implementation in C (clox). -

The Acton programming language
The Acton Programming Language
Write programs that seamlessly run as a distributed system over an entire data center or region. All without a single line of RPC code. Acton automatically persists the state of your application (orthogonal persistence) to a built-in distributed backend. No need to use a database or message broker ever again. 0 lines of persistence code. Built-in redundancy; Acton's transactional, high-performance distributed RTS can seamlessly resume application state after hardware failures. Never stop for an upgrade; Live upgrade your running application through compiler-supported code and data migration. Acton programs, and the actor model, work well from simple script-style applications on a single machine up to large distributed systems across a Data Center. Run at your scale. -

Wuffs
Wrangling Untrusted File Formats Safely
Wuffs is a memory-safe, zero-dependency library and domain-specific language for writing high-performance image codecs and related parsers. Instead of trusting ad-hoc C, Wuffs code is compiled to C with strong bounds, integer, and state checks inserted by construction, aiming to eliminate whole classes of security bugs without a heavy runtime. The design prioritizes predictable performance: decoders avoid dynamic allocation by default, return explicit “short read” signals, and run well in streaming or sandbox-free environments. The project ships battle-tested, CPU-friendly implementations for common image/container formats and bit-twiddly primitives like Huffman and checksum routines. Its standard library emphasizes portability and constant-time behavior where appropriate, which is valuable in security-sensitive contexts. Because the language is purpose-built, the resulting C output is small, auditable, and easy to embed in larger systems. -

Ravi Programming Language
Ravi is a dialect of Lua, featuring limited optional static typing
Ravi Programming Language is a derivative of Lua 5.3 with limited optional static typing and MIR-based JIT compiler. Ravi is a derivative/dialect of Lua with limited optional static typing and JIT/AOT compilers. The name Ravi comes from the Sanskrit word for the Sun. Lua is perfect as a small embeddable dynamic language so why a derivative? Ravi extends Lua with static typing for greater performance under JIT compilation. However, static typing is optional and therefore Lua 5.3 programs are also valid Ravi programs. There are other attempts to add static typing to Lua (e.g. Typed Lua but these efforts are mostly about adding static type checks in the language while leaving the VM unmodified. So the static typing is to aid programming in the large - the code is eventually translated to standard Lua and executed in the unmodified Lua VM. -

Wren
Wren is a small, fast, class-based concurrent scripting language
Think Smalltalk in a Lua-sized package with a dash of Erlang and wrapped up in a familiar, modern syntax. The VM implementation is under 4,000 semicolons. You can skim the whole thing in an afternoon. It's small, but not dense. It is readable and lovingly commented. A fast single-pass compiler to tight bytecode and a compact object representation help Wren compete with other dynamic languages. There are lots of scripting languages out there, but many have unusual or non-existent object models. Wren places classes front and center. Lightweight fibers are core to the execution model and let you organize your program into an army of communicating coroutines. Wren is intended for embedding in applications. It has no dependencies, a small standard library, and an easy-to-use C API. It compiles cleanly as C99, C++98 or anything later. -

Emojicode
World’s only programming language that’s bursting with emojis
Emojicode is an open-source, full-blown programming language consisting of emojis. As a multi-paradigm language, Emojicode features object orientation, optionals, generics, closures, and protocols. Emojicode compiles native machine code using lots of optimizations that make your code fast. Emojicode comes with a comprehensive set of default packages. And you can easily write your own. We believe that Emojis have expressive force. Let’s use that to make programming more fun and accessible. Emojicode is a straightforward language to learn, whatever background you have. Our documentation is known to be excellent and stuffed with walk-through guides and examples. Before you install Emojicode make sure you have a C++ compiler and linker installed. clang++ or g++ are fine, for instance. The Emojicode compiler can only link binaries if such a compiler is available. -

Ficl is a lightweight, embeddable scripting language designed to be incorporated into other programs, including memory constrained embedded systems. Ficl conforms to the 1994 ANSI Standard for Forth, and provides several useful extensions including object oriented programming that can wrap compiled code and hardware interfaces. 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. Ficl includes a simple but capable object model that can wrap existing data structures. Applications include scripting, hardware bring-up, rapid prototyping, and system extensions.
