• Viivi IDE [Viivi Integrating learning (and Development) Environment]
  • This is a multi-window environment for learning (and development) by Scheme beginners built on top of the Scheme language processor Viivi kernel using the GUI system of Java/Swing.
    
  • components
    • controller ... interacting with the user
    • argument-command window ... showing/editing the argument-commands
    • input-port window ... showing the input contents from an input-port
    • output-port window ... showing the output contents to an output-port
    • table windows ... showing various internal states of Viivi kernel
    • and more (e.g., the cell-space window) which are disabled in this version
  • menus and setting panels
    • menus ... prepared for various functions on the menu-bar of the controller and pop-up menus of the windows
    • setting-panels ... shown from the "setting" menu of the controller and from the pop-up menus of the windows to customize Viivi kernel and Viivi IDE.
• VITSE
  • This is a set of the functions built in Viivi IDE, interacting with the user to control and to visualize the evaluation process of Viivi kernel.
    It works as a 'TUTOR' for the Scheme programming, showing the internal evaluation process step by step, to help the user's understanding.
  • various functions
    • Trace-Output ... An evaluation process is shown with a trace-line connecting its input and output.
      Procedure calls and the side-effects, such as updates of bindings and data-structures, are also shown.
    • Evaluation-Lit ... During evaluation, a target of processing and evaluation, together with its related objects, are indicated with (by default) orange cursors in real time.
    • Selection-Lit ... During a halt, a selected target of the user's interest, together with its related objects, are indicated with (by default) violet cursors.
    • Watch ... Not only the break-points in the source codes, which are available in many other IDEs, but also arbitrary Scheme objects, bindings, procedure calls, and so on, can be watched by marking them.
