Envision
A visual programming IDE for object-oriented languages
Welcome to Envision

About

The Envision project aims to develop an IDE for object-oriented languages that features a visual structured code editor and is used for large-scale software development.

Envision is an open-source project using the BSD license. The project is based on the Qt framework and is cross-platform. Envision was originally developed at ETH Zurich in the context of Dimitar Asenov's PhD studies.

To read about the motivation for building Envision and find out what are some of the key ideas for the IDE, please see the motivation page.

Our CHI'16 talk presenting the results of a user study which shows that Envision's rich visualizations can substantially improve the understanding of code structure, compared to syntax highlighting.

Development status

Envision is still a proof of concept prototype and can not be used for programming yet. Nevertheless the current version illustrates some of the key visualization and interaction concepts for the IDE.

Envision currently runs on Linux and Windows. Development is done in Linux. There are two code branches on GitHub:

Implemented features

Missing features required for basic usability
