Take a look at Tim Wagner's thesis:


Tim A. Wagner. Practical Algorithms for Incremental Software Development
Environments Ph.D. Dissertation, Report No. UCB//CSD-97-946


http://sunsite.berkeley.edu:80/Dienst/UI/2.0/Describe/ncstrl.ucb%2fCSD-97-946?abstract=


I had used his incremental lexing algorithm to construct an editor
that does just what you describe -- relex at each keystroke. His
algorithm is capable of driving any batch lexer that provides a little
support for maintaining lexer states; Tim used flex and I used JavaCC.


As far as representation goes, I suggest you use linked list of tokens
as your data structure.


Marat.
