Racket

7.6
14 February 2020

Popular variant of the Scheme programming language.

Overview

Racket is a popular variant of the Scheme programming language. Its features and benefits include:

  • Grow your Program: Racket's interactive mode encourages experimentation, and quick scripts easily compose into larger systems. Small scripts and large systems both benefit from native-code JIT compilation. When a system gets too big to keep in your head, you can add static types.
  • Grow your Language: Extend Racket whenever you need to. Mold it to better suit your tasks without sacrificing interoperability with existing libraries and without having to modify the tool chain. When less is more, you can remove parts of a language or start over and build a new one.
  • Grow your Skills: Whether you're just starting out, want to know more about programming language applications or models, looking to expand your horizons, or ready to dive into research, Racket can help you become a better programmer and system builder.

What's new in Racket

Version 7.6:
  • DrRacket’s scrolling has been made more responsive.
  • DrRacket’s dark mode support is improved for Mac OS and Unix.
  • Racket CS is ready for production use. We will work to further improve Racket CS before making it the default implementation, but it now consistently passes all of our integration tests and generally performs well. (Compiled code remains significantly larger compared to the default implementation.)
  • The Web Server provides fine-grained control over various aspects of handling client connections (timeouts, buffer sizes, maximum header counts, etc.) via the new "safety limits" construct.
  • Using this new construct, we have decreased the web server’s default level of trust in client connections and made it detect additional, maliciously constructed requests. Resource-intensive applications may need to adjust the default limits (for example, to accept large file uploads). In trusted settings, they can be disabled completely by starting the web server with #:safety-limits (make-unlimited-safety-limits).
  • The Web Server’s handling of large files is improved, and its latency for long-running request handlers is reduced.
  • The Macro Stepper has a new macro hiding algorithm that tracks term identity through syntax protection (see syntax-arm), making macro hiding work more reliably. Its UI indicates protected and tainted syntax.
  • The Racket documentation includes a "building and contributing" guide.

What a fantastic development environment. I do wish, though, that DrRacket was more like TextMate or Emacs in some ways, but there is so much to like that I can't discount it.
