What is Viivi IDE?

Viivi IDE (Viivi Integrating learning [and Development] Environment)
is a GUI built on top of Viivi kernel.
The background image of the new top-page was created using the desktop-capture of testing on Viivi IDE in the author's development environment.

• Viivi IDE is an IDE of multi-window system composed with a controller, an argument-command window, input-port windows, output-port windows, tables which show the internal states of Viivi kernel.
• User can control the evaluating process of Viivi kernel step by step using the buttons on the controller and the keyboard.
  
• It is designed for the beginners to use intuitively and easily:
  • The foreground color of the strings is common for each kind of the targets which the strings express.
  • The background color and the design are individually assigned for each kind of the window.
  • The interfaces frequently-used for the interaction with Viivi kernel, such as the menu-bar, the buttons, the speed-slider, the state-line, and the input-text-line, are integrated on the controller.
  • Various functions can be used from the pop-up menus on each window according to the current state.
  • The user can customize Viivi kernel and Viivi iDE using the setting panels prepared for them respectively.
  • Size and location, together with open/close-state, of each window can be changed anytime.
  • Auto-arrangement functions, for all of the windows and for each group of the windows respectively, are implemented.
• IDE configuration is saved in the configuration file viivi.ide.vcnf.
  This enables the IDE restored to the previous state, when it is booted next time.
• A simple project (environment management and archive) function was newly implemented for beginners.
  Just by setting a project, the environment management function lets the user free from setting the environment every time when Viivi IDE boots.
  The multiple files registered for the project (including the user's source files, text files, and data files) can be saved into a single archive file at an arbitrary time point.
  At any time later, the saved environment can be restored from the archive file.
