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. -

Gleam
A friendly language for building type-safe, scalable systems!
Gleam's powerful static type system helps find and prevent bugs at compile time, long before it reaches your users. It also serves as a productive refactoring tool, enabling programmers to confidently make large changes to unfamiliar code, quickly and with low risk. For problems, the type system can't solve (such as your server being hit by a bolt of lightning) the Erlang virtual machine provides well-tested mechanisms for gracefully handling failure. Hunting down bugs can be stressful so Gleam's compiler provides clear and helpful feedback about any problems. We want to spend more time developing features and less time looking for bugs or deciphering cryptic error messages. Gleam builds on top of the Erlang virtual machine, a best-in-class runtime that has enabled companies such as Discord, Ericsson, Heroku, and WhatsApp to provide low-latency services at a global scale. Gleam takes full advantage of the Erlang runtime and adds no overhead of its own. -

gluon
A static, type inferred and embeddable language written in Rust
Gluon is a static, type inferred and embeddable language written in Rust. Gluon is a small, statically-typed, functional programming language designed for application embedding. Static typing makes it easier to write safe and efficient interfaces between gluon and the host application. Type inference ensures that types rarely have to be written explicitly giving all the benefits of static types with none of the typing. Marshalling values to and from gluon requires next to no boilerplate, allowing functions defined in Rust to be directly passed to gluon. Gluon supports Unicode out of the box with utf-8 encoded strings and Unicode codepoints as characters. Gluon is a garbage-collected language but uses a separate heap for each executing gluon thread. This keeps each heap small, reducing the overhead of the garbage collector. Gluon is written in Rust, which guarantees thread safety. Gluon keeps the same guarantees, allowing multiple gluon programs to run in parallel. -

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. -

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. -

OCaml
The core OCaml system: compilers, runtime system, base libraries
OCaml is a general-purpose, industrial-strength programming language with an emphasis on expressiveness and safety. OCaml’s powerful type system means more bugs are caught at compile-time, and large, complex codebases are easier to maintain. This makes it a good language for running critical code. At the same time, sophisticated inference makes the type system unobtrusive, creating a smooth developer experience. OCaml has two compilers. One is a bytecode compiler that generates small, portable executables and is very fast. The other is a native code compiler that produces more efficient machine code; its performance matches the highest standards of modern compilers. OCaml has great support for the most popular editors. VS Code is recommended for beginners, and for power users there is deep integration with Vim and Emacs. OCaml has a rich and dynamic community and best-in-class tooling. -

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. -

The Ballerina programming language
The Ballerina Programming Language
Ballerina is an open-source programming language for the cloud that makes it easier to use, combine, and create network services. Network primitives in the language make it simpler to write services and run them in the cloud. Structural types with support for openness are used both for static typing within a program and for describing service interfaces. Type-safe, declarative processing of JSON, XML, and tabular data with language-integrated queries. Explicit error handling, static types, and concurrency safety, combined with a familiar, readable syntax make programs reliable and maintainable. Easy and efficient concurrency with sequence diagrams and language-managed threads without the complexity of asynchronous functions. Programs have both a textual syntax and an equivalent graphical form based on sequence diagrams. -

V Programming Language
Simple, fast, safe, compiled language for developing software
Simple language for building maintainable programs. You can learn the entire language by going through the documentation over a weekend, and in most cases, there's only one way to do something. This results in simple, readable, and maintainable code. Despite being simple, V gives a lot of power to the developer and can be used in pretty much every field, including systems programming, webdev, gamedev, GUI, mobile, science, embedded, tooling, etc. V avoids doing unnecessary allocations in the first place by using value types, and string buffers, promoting a simple abstraction-free code style. Most objects (~90-100%) are freed by V's auto-free engine: the compiler inserts necessary free calls automatically during compilation. A remaining small percentage of objects is freed via GC. The developer doesn't need to change anything in their code. "It just works", like in Python, Go, or Java, except there's no heavy GC tracing everything or expensive RC for each object. -

Fennel
Lua Lisp Language
Fennel is a programming language that brings together the speed, simplicity and reach of Lua with the flexibility of a lisp syntax and macro system. Full Lua compatibility: Easily call any Lua function or library from Fennel and vice-versa. Zero overhead: Compiled code should be just as efficient as hand-written Lua. Compile-time macros: Ship compiled code with no runtime dependency on Fennel. Embeddable: Fennel is a one-file library as well as an executable. Embed it in other programs to support runtime extensibility and interactive development. Anywhere you can run Lua code, you can run Fennel code. Fennel is a lisp that compiles to Lua. It aims to be easy to use, expressive and has almost zero overhead compared to writing Lua directly. Building Fennel from source allows you to use versions of Fennel that haven't been released, and it makes contributing to Fennel easier. -

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. -
