    Human Speakable Programming Language

    foundation of the General Intelligence Operating System

    HSPL is Human Speakable Programming Language, allowing for communication between human-to-computer and human-to-human in the same language. This project has moved to http://sourceforge.net/p/spel We are currently working on human-to-computer programming-language with mostly English base vocabulary. Though once we have that, we plan to add support for other world Languages, including Chinese, Spanish, Russian, Arabic, Hindi, among others. Eventually HSPL shall be the foundation of GIOS the General Intelligence Operating System. Which is an open source operating system, that can be used for intelligent robots, computers and technological host-bodies. Regularly post on blog about HSPL at http://weyounet.info/?s=hspl

    The Ballerina programming language

    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.

    TypeSpec

    TypeSpec

    Language for defining cloud service APIs and shapes

    TypeSpec is a language for defining cloud service APIs and shapes. TypeSpec is a highly extensible language with primitives that can describe API shapes common among REST, OpenAPI, gRPC, and other protocols. TypeSpec is excellent for generating many different API description formats, client and service codes, documentation, and many other assets. All this while keeping your TypeSpec definition as a single source of truth. Using TypeSpec, you can create reusable patterns for all aspects of an API and package those reusable patterns into libraries. These patterns establish "guardrails" for API designers and make it easier to follow best practices than to deviate from them. TypeSpec also has a rich linter framework with the ability to flag anti-patterns as well as an emitter framework that lets you control the output to ensure it follows the patterns you want.

    cowbel (obsolete)

    An experimental programming language

    cowbel is a minimalist experimental programming language. It features strict types, static compilation into real machine code (via C), an object oriented system based on interfaces and composition, generics, no null, and a global garbage collector. It is intended to produce fast, tight code for use in systems programming, and to show that you don't need a complex language to be expressive and usable. We've moved!
