Also, recently we started working on new text model. With the goal to replace an clean Text, text editing and text layout in our system (and sure thing , rendering). This is also requires a lot of work.
I am very interesting in details. Do you have description or code somewhere?
I always think about new text editor implementation based on Presenty. I want remove all hardcoded stuff like cursor navigation arrow keys, copy/paste shortcuts, keyboard based characters input. User should have facility to specify how execute such primitive actions. For example, user can just draw characters on screen to input it or input it by voice. User can add buttons to move cursor, can add visual keyboard (maybe native for OS).
Take a look at http://www.smalltalkhub.com/#!/~sig/TxText there's already a working (since tests are green ;) implementation of new text model. And, as you said, you don't have to deal with hardcoded stuff. The text model provides a 'position' API, which can be used to navigate text directly: - moveLeft, moveRight, lineUp, lineDown etc There's also a 'selection' model, which allows you to 'cut' , or 'replace' portions of text at given position. So, the text model designed by having text editor in mind. I am working on making attributes work for it (bold/italic etc).. and then renderer, layouting and editor(s). Well, actually editor will be most simplest piece of puzzle after i finish all the bottom layers :) If you wanna join and help, you're wellcome.. because i am stretched today between many things: NB, Athens, VMs
And I think about subclassing TextMorph to implement my ideas. But TextMorph is so crappy. So I will be happy if somebody give me clean implementation of TextMorph.
hehe , stand in a line then. You will be after me :) Everyone wants something better than TextMorph, but nobody wants to make it real :) -- Best regards, Igor Stasenko.
