  • Racket version 8.2 is available.

    We welcome two new Racket books:
    (1) Racket Programming the Fun Way
    (2) Don’t Teach Coding: Until You Read this Book
  • Racket, the Programming Language

  • Racket is a mature and stable product. From the beginning, it has supported cross-platform graphical programming (Windows, macOS, Linux).

  • Racket includes a rich set of libraries, covering the full range from web server apps to mathematics and scientific simulation software.

  • In Racket, programmers define their own loops with powerful macros. Indeed, these macros are so powerful that programmers make entire domain-specific languages as libraries. No tools, no Makefiles required.

  • Racket is the first language to support higher-order software contracts and safe gradual typing. Programmers can easily deploy these tools to harden their software.

  • Racket comes with support for major editors. The main bundle includes an innovative and extensible interactive development environment that has inspired other IDE projects.

  • Newcomers describe the on-line Racket community as extremely friendly and helpful. Everyone is welcome to ask any question and everybody is welcome to contribute to the open-source code base.

  • Racket, the Language-Oriented Programming Language

    Racket allows programmers to add new syntactic constructs in the same way that other languages permit the formulation of procedures, methods, or classes. All you need to do is formulate a simple rule that rewrites a custom syntax to a Racket expression or definition.

    Little macros can particularly help programmers with DRY where other features can’t. The example on the left above shows how to define a new syntax for measuring the time a task takes. The syntax avoids the repeated use of lambda. Note also how the macro is exported from this module as if it were an ordinary function.

    Racket comes with a comprehensive suite of libraries: a cross-platform GUI toolbox, a web server, and more. LiuShan Lenovo Tab E10 Wireless Keyboard Case, Detachable Wirele are a single command away: 3D graphics, a bluetooth socket connector, color maps, data structures, educational software, games, a quantum-random number generator, scientific simulations, web script testing, and many more.

    Macros work with these tools. The example on the left above shows the implementation of a small number-guessing game. It is implemented in the GUI dialect of Racket, and demonstrates a number of language features.

  • Getting to know the full Racket macro system will feel liberating, empowering, dazzling—like a whole new level of enlightenment. Developers can easily create a collection of co-operating macros to implement algebraic pattern matching, simple event-handling, or a MITILLY Girls Loose Plain 3/4 Sleeve Casual Pocket Ruffle Swing.

    While Racket is a functional language, it has offered a sub-language of classes and objects, mixins and traits, from the beginning. The macro-based implementation of a Java-like class system lives in a library and does not need any support from the core language. A Racket programmer can thus combine functional with object-oriented components as needed.

  • Some languages convey ideas more easily than others. And some programming languages convey solutions better than others. Therefore Racket is a language for making languages, so that a programmer can write every module in a well-suited languages.

    Often an application domain comes with several languages. When you need a new language, you make it—on the fly. Open an IDE window; create a language right there, with just a few keystrokes; and run a module in this new language in a second IDE window. Making new languages really requires no setup, no project files, no external tools, no nothing.

  • Racket comes with its own IDE, DrRacket (née DrScheme), and it sports some unique features. For example, when a programmer mouses over an identifier, the IDE draws an arrow back to where it was defined.

    A programmer immediately benefits from DrRacket while using an alternative language, say Typed Racket. Racket macros, even complex ones and those used to make new languages, record and propagate a sufficient amount of source information for DrRacket to act as if it understood the features of the new language.

  • Racket programmers usually love parentheses, but they have empathy for those who need commas and braces. Hence, building languages with conventional surface syntax, like that of datalog, is almost as easy as building parenthetical languages.

    Racket’s ecosystem comes with parsing packages that allow developers to easily map any syntax to a parenthesized language, which is then compiled to ordinary Racket with the help of Racket’s macro system. Such a language can also exploit the hooks of the IDE framework, so that its programmers may take advantage of Racket’s IDE.
