However, though it was designed for Japanese it works with English.
Basically, after you type a word, you select it from a scrollable list of alternatives with the space-bar - there's alternatives in Japanese, but one is also in English.
Then later, when you start typing the word, it comes up as an option right after the first character.
It's very potent, and super on the zaurus, if you write a lot, after you have typed a couple of hundred words, it will remember your word selections and you mostly end up just typing first two letters of the word or so and then get offered the word you wanna type. Very good.
Now, Prime's homepage is at: http://taiyaki.org/prime/
Prime needs Ruby, which has been compiled for pdaXrom, it's at: http://www.pdaxrom.org/unstable/ruby_1.8.2_armv5tel.ipk
Then it needs suikyo, sary, and sary bindings for ruby.
I've compiled Prime, prime-dict, suikyo, and sary.
I'm including the sary ipk with this post.
Now the only thing missing to compile is sary's ruby bindings which is a 9k file, you can get it here: http://sary.sourceforge.net/sary-ruby-1.2.0.tar.gz
But it's not compiled by the regular configure, make, make install way. Instead the Makefile is generated by Ruby. So you untar it, run "ruby extconf.rb" and then you can do make etc...
For this you first need to install ruby and sary.
But I can't get this "ruby extconf.rb" to work, I get an error saying:
checking for sary.h... no
But sary.h is in /usr/local/include/ that's where it's installed when you install sary.
So I'm guessing it's some ruby or sary config setup, but can't figure out how to fix this.
Can someone try and find out how to do it. It's just the last little step and we'll have this fenomenal way to input text predictively, super fast under pdaXrom.
