    MicroPython

    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.

    Idris 2

    Idris 2

    A purely functional programming language with first class types

    In type-driven development, types are tools for constructing programs. We treat the type as the plan for a program, and use the compiler and type checker as our assistant, guiding us to a complete program that satisfies the type. The more expressive the type is that we give up front, the more confidence we can have that the resulting program will be correct. In Idris, types are first-class constructs in the language. This means types can be passed as arguments to functions, and returned from functions just like any other value, such as numbers, strings, or lists. This is a small but powerful idea, enabling relationships to be expressed between values; for example, that two lists have the same length. Assumptions to be made explicit and checked by the compiler. For example, if you assume that a list is non-empty, Idris can ensure this assumption always holds before the program is run.

    The Acton programming language

    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.

    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.

    BMDFM

    BMDFM

    Binary Modular DataFlow Machine (BMDFM)

    Binary Modular DataFlow Machine (BMDFM) is a software package that enables running an application in parallel on shared memory symmetric multiprocessing (SMP) computers using the multiple processors to speed up the execution of single applications. BMDFM automatically identifies and exploits parallelism due to the static and mainly dynamic scheduling of the dataflow instruction sequences derived from the formerly sequential program. The BMDFM dynamic scheduling subsystem performs a symmetric multiprocessing (SMP) emulation of a tagged-token dataflow machine to provide the transparent dataflow semantics for the applications. No directives for parallel execution are needed. More info: http://www.bmdfm.com

    Checked C

    Checked C

    Checked C is an extension to C that lets programmers write C code

    Checked C is an extension to C that lets programmers write C code that is guaranteed by the compiler to be type-safe. The goal is to let people easily make their existing C code type-safe and eliminate entire classes of errors. Checked C does not address use-after-free errors. Checked C adds static and dynamic checking to C to detect or prevent common programming errors such as buffer overruns and out-of-bounds memory accesses. The goal of the project is to improve systems programming by making fundamental improvements to C. This repo contains sample code, the extension specification, and test code. The Checked C project is extending the C programming language so that programmers can write more secure and reliable C programs. The project is developing an extension to C called Checked C that adds checking to C to detect or prevent common programming errors such as buffer overruns, out-of-bounds memory accesses, and incorrect type casts.

    Emojicode

    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.
