  • Tycho 0.2 Overview

    Tycho is an object-oriented syntax manager with an underlying heterogeneous technical rationale. It provides a number of editors and graphical widgets in an extensible, reusable framework. The editors for textual syntaxes are modeled after emacs in the sense the emacs key bindings are used when possible. Editors for visual syntaxes will be more diverse. The system documentation is integrated, using a hypertext system compatible with the worldwide web. Tycho is designed to provide the user interface for other programs. At Berkeley, it is used with the Ptolemy system, a heterogeneous design environment. It is also useful on its own as a software development environment. The development of Tycho has proceeded almost entirely within the Tycho environment since its very early days.

    Version 0.2 is the third public release of Tycho as a standalone system. It runs under the vanilla Itcl 2.2 with no changes to the executable. (Note that Ptolemy0.6 was shipped with Itcl2.0. Tycho0.2 will not work with Itcl2.0 or Itcl2.1)

    Tycho0.2 includes both textual and graphical editors, though the textual editors are more developed.

    Tycho0.2 can be obtained from http://ptolemy.eecs.berkeley.edu/tycho/Tycho.html

    Here is a summary of the capabilities:

    Tycho Kernel

    Textual Editors and Shells

    In addition to the basic Emacs-like text editor described above and the Tcl shell, a number of additional editors and shells have been designed. The editors provide capabilities similar to those of Emacs modes, although they have the potential to go beyond Emacs modes because of the planned inclusion of graphical elements.

    The editors and shells included in release 0.2 are:

    Graphical Editors

    tydoc - The Tycho documentation system

    Tycho 0.2 also includes tydoc, a script that converts itcl to html.
