Wolf Wejgaard: Yet another programming system? Holon is new in Tcl but is based on over 15 years experience with Holonforth under DOS.
Main features:
See http://holonforth.com/new/holon.html for details. Holon is presently available as a free starpack for Windows (MIT license).
This is Holon, handling its own source:
Acknowledgements: Holon is built on Wikit. It started by adding a book-structure (HolonWikit), then the wikit pages turned into program containers for source and comments. The hardwired links are replaced by dynamic links to page titles=names. Comments are edited and saved in Tk format, source is saved unformatted. Some Wikit features remain. IOW, see Holon as a local Wikit in disguise.
