Python/Javascript: WYSIWYG Html Editor - Handle Large Documents Fast And/or Design Theory
Background: I am writing an ebook editing program in python. Currently it utilizes a source-code view for editing, and I would like to port it over to a wysiwyg view for editing. T
Solution 1:
Can i suggest a complete another approach ? Since your ebook is only <p></p>
:
- Split the text on
<p></p>
to get an indexed array of all your paragraphs - Make your own pagination system, and fill the screen with N paragraphs, that automatically get enough text to show from the indexed array
- When you are doing selection, you can use [paragraph index + character index in the paragraph] for selection start / end
- Then implement cut/copy/paste/delete/undo/redo based on thoses assumptions.
(Note: when you'll do a selection, since the start point is saved, you can safely change the text on the screen / pagination, until the selection end.)
