Tycho 0.1.1 Release Notes

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 has been designed primarily for use with the Ptolemy system, a heterogeneous design environment from U.C. Berkeley, but it is also useful on its own.

Version 0.1.1 is the second public release of Tycho as a stand-alone system. It runs under the vanilla Itcl 2.1 with no changes to the executable. (Note that Ptolemy0.6 was shipped with Itcl2.0. Tycho0.1.1 will not work with Itcl2.0)

Tycho0.1.1 includes both textual and graphical editors, though the textual editors are more developed.

Tycho0.1.1 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 the potential goes beyond what emacs can do because of the future inclusion of graphical elements.

The editors and shells included in release 0.1.1 are:

Graphical Editors

tydoc - The Tycho documentation system

Tycho0.1.1 also includes tydoc, a script that converts itcl to html.
