Text editor theory?

Question

As I'm always dissatisfied with existing editors, a project I always wanted to start is my own text editor. However doing text editing is serious business.Besides analyzing the source code of existing text editors, is there any book or other resource (like academic work) about this topic? I'm interested especially in something that teaches how to handle memory and how to manage text insertion (if you have a 100 MB file and want to add a char at *x* position, you can't just `memmove` the huge text block...).

Answer 1

No it is easier than that....

In visual basic you can create a text editor quite easily....

It is a large text box with vertical and horizontal scroll bars....

The hardest part is loading the text file from disk into the text block on OPEN

and over-writing the contents of the text box back to the file on SAVE...
