[edit] News

Version 4.1 was released on January 6 and fixes a bug that lead to a crash in worldbuilder.

Version 4.0 was released on November 9 and has a redesign of the GUI to provide more space for the code editor. The two editors are now packed in a notebook widget. A nasty bug in the code editor was also fixed.

Version 3.4 was released on October 27 and fixes a bug that hangs Gvr on newer XO software. This is a recommended update.

[edit] About GvR

Guido van Robot is a localized minimalistic programming language providing just enough syntax to help students learn the concepts of sequencing, conditional branching, looping and procedural abstraction. Its biggest strength is that it permits this learning in an environment that combines the thrill of problem-solving with instant visual feedback. In short, it is an interactive, introductory programming language that is excellent for learning the basic concepts of programming, applicable in any high-level language. Best of all, it's a whole lot of fun, too!

At this point, you are probably asking yourself, What is GvR, specifically? The gist of it is that it is a robot represented by a triangle on the screen that moves around in a world made up of streets and avenues, walls and beepers, which Guido can collect or set. His actions are completely guided by a program written by the user.

One other item of interest about GvR is that it is a student-created project. GvR was initially written by students at Yorktown High School in Arlington, Virginia, with the help of professional programmers serving as mentors. You can navigate to the History page to learn more about this part of the project.
