Source Academy is a web-based open-source integrated development environment (IDE) used for teaching computer programming in the programming languages JavaScript and Source, developed for the textbook Structure and Interpretation of Computer Programs, JavaScript Edition (SICP JS). In addition to JavaScript, it implements the JavaScript sublanguages Source §1, Source §2, Source §3, and Source §4, which are designed to be just expressive enough to support all examples of the respective chapter of the textbook. The IDE supports the main mental models for program evaluation of SICP JS with custom-built debugging tools: the substitution model with a stepper tool,[1] and the environment model with an environment model visualizer.[2]
Licensing[edit]
Source Academy is released by the Source Academy Organization under an Apache license.[3] The SICP JS textbook (integrated in Source Academy) is released under a Creative Commons license, and the programs in SICP JS are covered by the GNU General Public License Version 3.
Releases[edit]
Since 2018, Source Academy saw a major release every two years.
| Version name | Date | Main changes |
|---|---|---|
| Cadet | July 2018 | - |
| Knight | January 2020 | Advanced editing features, stepper, environment model visualizer |
| Rook | December 2021 | Modules, full-JavaScript support, SICP JS integration |
Architecture[edit]
Source Academy is a web application developed in TypeScript using React JS. The programming language implementations are factored out into a separate Node.js package called js-slang.[4] The sections of the interactive edition of SICP JS are dynamically loaded from the textbook repository.[5]
Robotics[edit]
Source Academy provides extensive support for robotics programming, using a compiler to a virtual machine language SVML and an automated workflow for running compiled robot control software on a virtual machine deployed on the robot.[6] The virtual machine for SVML is ported to the Android and EV3 operating systems.[7][8]
Modules[edit]
Source Academy supports the dynamic loading of JavaScript modules from trusted modules repositories[9] using JavaScript's import syntax. For example, the sound module allows the programming of additive functional audio processing,[10] and the modules rune, curve, and pix_n_flix support online graphics and video stream processing.[11]
Extension[edit]
Source Academy @ NUS is an extension of Source Academy designed for teaching courses based on SICP JS.[12] It features an Elixir-based backend for keeping track of student submissions of exercise assignments, and for manual and automated grading of submissions. A system for storing and visualizing student achievements and an optional graphic-novel-style game enhance student motivation. Instructors can create new courses, manage students and staff for their courses, and upload exercise assignments.
