Comment on attachment 274216 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=274216&action=review Since text checker is defined in terms of string views, not the DOM, seems the right architecture would be to convert the selection to offsets within the string at the call sites, rather than actually passing the VisibleSelection object down. Is there a straightforward way to do it that way instead? > Source/WebCore/ChangeLog:10 > + Pass the Frameâs section to a handful of spelling checking methods that call Frame's selection, not Frame's section

Maybe we should just wrap -checkString and -requestCheckingOfString: to avoid the repetition?

So I chose to do it this way because I thought it would pave the way for some more straightforward patches in the future. That being said, I do not have a great understanding of any architectural decisions guiding these WebCore classes. So if you think it's a better/cleaner architecture here to stick to the offset, then I would be happy to do that. Do you think that's better even if I add some additional parameters in the future?
http://trac.webkit.org/changeset/198306 I will follow-up with Darin to see if a follow-up patch is in order.

Before this change, these functions were an abstract interface to spell checking that was independent of the DOM. After the change, they are hooks for spell checking that are not independent of the DOM. I don’t have a strong feeling about which design is better, but I don’t like place we have landed with the division of responsibilities where extracting the text to spell check is a job for the caller, but interpreting the selection position is a job for the spell checking functions. I’d prefer that the work of extracting the text to spell check and the other contextual information needed to correctly check from the DOM was either done entirely by the caller or entirely by the spell checking functions. This is not an urgent issue but nice to resolve in the longer term. We can talk in person about this at some point.
