DrRacket

DrRacket is an integrated development environment for the Racket programming language, and it is the primary editor bundled with the Racket distribution. It began as DrScheme, a teaching-oriented IDE developed by the PLT Scheme project, and was later renamed to DrRacket as the language evolved into Racket. The environment provides a source editor with syntax highlighting, automatic indentation, bracket matching, and error highlighting, along with a REPL for interactive programming.

A key feature of DrRacket is its support for multiple languages and teaching languages. Users can select different language levels and teaching languages (such as Beginning Student or How to Design Programs) to tailor the programming experience, making it suitable for both beginners and advanced users. The IDE also includes a stepper, a debugger, and an integrated interactions window, enabling iterative development and debugging within a single workspace. DrRacket emphasizes an approachable workflow that blends editing, evaluation, and testing.

DrRacket is cross-platform, available on Windows, macOS, and Linux. It is released as part of the open-source Racket project, distributed under a BSD-like license, and maintained by the Racket community. As a general-purpose IDE, it supports development in Racket modules, packages, and libraries, while continuing to serve as a useful tool for education and research in programming languages and computer science pedagogy.

In summary, DrRacket provides an accessible, extensible environment for writing, evaluating, and debugging Racket programs, with features geared toward both learners and experienced programmers.
