Just return a boolean for the TreeWalker filter fn. This diverges from the spec,
but since the goal of this implementation is not to fully implement the spec
and we're never going to use a native implementation, this doesn't matter and
the code is easier to read when the function is just returning a boolean like
any normal filter function.
* Be more liberal in tld, as there are now a billion new ones, of every length.
* Fix bug where if the URL contains an @ it would add it as a mailto link
instead.
Set the defaultBlockProperties property on a squire instance to an object and
it will use these properties when it has to create a new default block element.
If a text node at the beinning of a block began with white-space, it would mean
some situations where we should be doing all the transformations for
enter/delete/backspace were being left to the browser.
* Hit tab to increase list depth, or call increaseListLevel method.
* Hit enter on a blank item to decrease list depth, or call decreaseListLevel method.
The clean functions used a `this` reference to call createElement, but are
called as functions not methods so `this` is undefined. Instead, we'll get the
ownerDocument off the nodes passed in, then call the createElement function
directly.
This is now an instance method, whereas before it was global. Annoyingly, we
need to access this from from within fixCursor which has no reference to the
RTE instance itself (and it would be a pain to pass one down). For now, just
referring to the global `editor` variable if it exists (i.e. if the script
loaded in an iframe). Need a better solution longer term though.
* If you load the squire.js script into a top-level page rather than an iframe,
it will add a Squire constructor to the global scope.
* The Squire constructor can be used to instantiate multiple instances on the
same page without having to load/parse/execute the full code every time.
* For each instance, create a new iframe, then call `new Squire( document )`,
with the document node for each iframe.
If you copy a portion of text from word, it includes an image version of the text as well as an HTML version. On paste, we now ignore the image
representation on the clipboard if an HTML representation is present, so that
the text pastes as expected, rather than as an image.
If you removed an event listener whilst it was being fired, this would alter the
list of handlers, which would cause the fireEvent function to read past the end
of the array (and to skip the next listener). Now, we clone the array of
listeners before firing, so adding/removing listeners has no effect on an
already firing event.
Firefox incorrectly goes back/forward in history instead of moving the cursor to
the beginning/end of the line when you press cmd-left/right on a mac. We now
override this to do the right thing.
When cleaning up pasted content, we remove any empty inline tags. However, we
should not be stripping <img> tags (which are of course both inline and empty).
Webkit needs a special placeholder text node as it can't focus empty text nodes.
This was being cleaned up too early, before the user had a chance to enter any
text.
