I’ve updated Paradigmatic quite a lot recently. You can download the beta version 0.3.0 and give it a whirl; it should be much more functional than the last version.
A full list of what’s changed can be found at http://paradigmatic.freney.org/download.html
The paradigm data entered so far covers all the standard paradigms (all stems, for both ??? and ???, depending on your preference), plus all I-guttural and I-aleph forms. Isolated other paradigms exist, but don’t count on it.
If you try it, please let me know what works, what doesn’t. Let me know any mistakes I’ve made in paradigms (some I’ve had to make educated guesses for) – you can edit them yourself, but unless I’ve got it right at my end the next time you update the program it will overwrite your changes. This is something I may change in the future, but it’s hard to do gracefully, so I’m putting it off for when I have a little more time. Tell me if something doesn’t quite work how you think it ought to work.
Hope it’s useful for someone (other than me, that is).
