Web 2.0 has drastically shifted typical Web users from passive users to active developers. Web users share photos and videos, write blogs, and extend wiki pages. Yet end users need support to build their own applications on the Web. WEUP aims to provide the required tools for Web users to develop programmable artifacts on the Web. However, Web users have different domains of interest for development. Therefore, providing a one-off tool for all the Web users on the Web is not possible. WEUP provides a Web-based infrastructure for developing and sharing customizable EUP tools so that Web 2.0 communities can tailor them to create EUP integrated development environments according to their domain.
AgentWeb is an on-going project to develop a client-side Web-based end-user programming environment to be used by typical Web users and communities for developing and sharing interactive artifacts. AgentWeb consists of a plugin architecture for supporting development of interactive applications in different domains and provides an agent-based, event-based, visual programming paradigm for building interactive applications over DSLs of different application domains.
The Arakhnê.org Network Editor (NetEditor) is a Java component that permits you to edit and show connected graphs. The graph defines the constructs of a visual language, and NetEditor is able to render associated figures. NetEditor is based on a metamodel composed of the node, edge, and anchor (or ports) constructs. It has a strong separation of the visual-language constructs and the drawings. It provides tools to code graph-drawing layout algorithms. Two algorithms are provided: Ganswer-Sugiyama and Coulomb-Hooke force-based algorithms. Standard UI features are provided: graphical editing of the graph structure, depth levels for nodes and edges, undo, and redo, clipboard, and drag and drop management. The NetEditor API is able to export the graphs to GIF, JPEG, PNG, BMP, SVG, PDF, EPS, PDF, Graphviz DOT, GXL and GraphML. The document file formats used by NetEditor are GXL, GraphML, or NGR files (zipped GXL/GraphML).
Pythonect is an experimental general-purpose dataflow programming language based on Python. It provides both a visual programming language and a text-based scripting language. The text-based scripting language aims to combine the quick and intuitive feel of shell scripting with the power of Python. The visual programming language is based on the idea of a diagram with “boxes and arrows”.
