    ZPLDesigner

    ZPLDesigner

    A Zebra Programming Language (ZPL) IDE with embedded viewer

    ZPLDesigner is a free and easy-to-use software utility that allows you to create, preview and print label based on Zebra Programming Language (ZPL). ZPL commands ZPL Designer can help you to write ZPL code. The left panel provides a list of the main ZPL commands used to design a label. By hovering the mouse pointer over the desired ZPL command, a detailled description will be displayed on the top "Help" panel. Clicking on it will add this command to the ZPL editor. ZPL Viewer By pressing F5 or clicking on Preview button, ZPL Designer will display the result of you ZPL code on a Preview tab. You will be able to zoom/unzoom, rotate or save the generated label as an image. You can choose how to render your ZPL code: a local Zebra printer or by using the labelary.com webservice. An industrial ZPL printer with embedded website and network is required when you choose to use "Local Zebra Printer" as renderer.

    Crystal

    Crystal

    The crystal programming language

    Crystal’s syntax is heavily inspired by Ruby’s, so it feels natural to read and easy to write, and has the added benefit of a lower learning curve for experienced Ruby devs. Crystal is statically type checked, so any type errors will be caught early by the compiler rather than fail on runtime. Moreover, and to keep the language clean, Crystal has built-in type inference, so most type annotations are unneeded. All types are non-nilable in Crystal, and nilable variables are represented as a union between the type and nil. As a consequence, the compiler will automatically check for null references in compile time, helping prevent the dreadful billion-dollar mistake. Crystal’s answer to metaprogramming is a powerful macro system, which ranges from basic templating and AST inspection, to types inspection and running arbitrary external programs. Crystal uses green threads, called fibers, to achieve concurrency. Fibers communicate with each other using channels, as in Go or Clojure.

    Ruby

    Ruby

    Ruby programming language

    A dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming. He has often said that he is “trying to make Ruby natural, not simple,” in a way that mirrors life. Since its public release in 1995, Ruby has drawn devoted coders worldwide. In 2006, Ruby achieved mass acceptance. With active user groups formed in the world’s major cities and Ruby-related conferences filled to capacity. Ruby-Talk, the primary mailing list for discussion of the Ruby language, climbed to an average of 200 messages per day in 2006. It has dropped in recent years as the size of the community pushed discussion from one central list into many smaller groups.

    Human Speakable Programming Language

    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

    SC

    SC is a C based meta/programming language/environment

    SC is a C based/compatible language that uses a binary source code format and a "special" editor to provide a far more advanced programming and meta-programming environment. The basic philosophy is to "simplify" the "form" and not the "meaning" of C. SC allows you to write source code that can analyze and modify itself. Which in turn allows you to create far more compact and powerful libraries, templates, toolkits and simply source code, using techniques similar to aspect and/or language oriented programming. SCEdit is an editor that comprehends the source code on a level similar to the compiler, giving you feedback about anything that can be concluded from the source code. It can also interpret meta-functions from the source code to either analyze, modify or create new code, allowing you to automate a complex workflow for and from your source code. Furthermore SC can be both compiled, interpreted, and just in time compiled.
