12 years ago So you are saying that SCAYT should check and highlight words (anything separated by spaces) and after that you are saying that extra spaces and miss of space are not errors. So how exactly should it works?
That what I'm thinking:
1) Get content, strip all html tags, extra spaces, EOL characters, etc. 2) Get current lesson, join all phrases using space character. 3) If our 2 strings are equal then there are no errors in text, otherwise: 4) make diff -- ignore extra spaces and EOL -- treat missing space as error -- return array of all mis-typed word and highligth them

I'd like the SCAYT functionality to highlight only words that are mis-typed (don't match exact, case-sensitive letters or punctuation). By word, I mean anything separated by spaces.
I'd like it to check the whole document every time, so if you delete several words or even all the text in the box, it will continue to error check correctly.
I'd also like it to be able to adapt to missing/extra spaces. So if I miss a spaceor add an ex tra space while typing, subsequent correct words won't be marked as errors. Maybe I'm over-engineering it, but I think it'll need to use the McIlroy-Hunt longest common subsequence (LCS) algorithm. Unless you have a better idea. I found a JS implementation of it, but no idea how good it is: http://www.lshift.net/blog/2006/08/15/diff-for-javascript
Multiple spaces or returns where only one is required should not cause any errors.
