Source code available on request. We haven't determined yet how the two codebases fit and I made some yucky changes to foma proper,
so for now I want to discourage tinkering with what almost amounts to a temporary fork.
Please note that this software is an incomplete alpha version; it is somewhat usable but is really only suited to testing. Use at your own risk.

Compatibility

Features

• Easy regex compilation and viewing (AT&T Graphviz required).
• All common unary operations on machines available via menu items.
• define a machine by compiling it and then renaming it the machine list.
• IPA Palette-based symbol input window.
• Partial Japanese localization.
• Save both native (bundle containing machines and defines in foma native format) and Prolog file formats.
• Imports .lexc, single regex, and opens script-like files (one per line, prefixed with "re" or "def").
• Single-machine AT&T file export.

Fixed or Added in this Release

• It has app and document icons!
• Function definitions now compile.
• Recent regular expressions are saved in the document bundle.
• Various bug fixes.

Problems

• No documentation!
• Function definitions are not displayed anywhere in the interface yet.
• File saving does not preserve function definitions. Can foma even save these to a file?
• There are memory leaks in the foma regular expression parser and elsewhere.
• MED application prints to standard output instead of being capturable by the GUI.
• Defined and undefined machines are displayed potentially in a different order from previous save when a Terminus Est document is opened (the defines are always loaded last).
