FlyString is a flyweight string class that wraps a RefPtr<StringImpl>
known to be unique among the set of FlyStrings. The class is very
unoptimized at the moment.
When to use FlyString:
- When you want O(1) string comparison
- When you want to deduplicate a lot of identical strings
When not to use FlyString:
- For strings that don't need either of the above features
- For strings that are likely to be unique
Now expanding a tilde isn't hardcoded to just work for `cd`. It is instead
expanded while processing shell arguments. Autocompletion still doesn't
work, but this is definitely an improvement over the last iteration.
Remember the override cursor in GUI::Window and avoid sending a message
to WindowServer when possible.
This removes a lot of synchronous IPC between Browser and WindowServer,
which noticeably improves DOM event responsiveness. :^)
This patch adds the Event base class, along with a MouseEvent subclass.
We now dispatch MouseEvent objects for mousedown, mouseup and mousemove
and these objects have the .offsetX and .offsetY properties.
Both of those properties are hard-coded at the moment. This will be
fixed in the next patch. :^)
Object now has virtual get_own_property() and put_own_property() member
functions that can be overridden to provide custom behavior.
We use these virtuals to move Array-specific access behavior to Array.
- move() the property map when constructing ObjectExpression instead of
making a copy.
- Use key+value iterators to traverse the property map in the execute()
and dump() functions.
This function is ultimately supposed to be generic and allow any |this|
that has a length property, but for now it only works on our own Array
object type.
I'm not completely thrilled about Object::get() and Object::put() doing
special-case stuff for arrays, and we should probably come up with a
better abstraction for it.
But at least it works for now, which is really nice. :^)
This makes it possible to write shorter CSS. Instead of writing
.foo {
border-width: 3px;
border-style: solid;
border-color: blue;
}
it is now possible to write
.foo {
border: 3px solid blue;
}
while the order of values is irrelevant.
Currently only the basic values are supported. More values should be
added in the future.
Three more value specific parse functions were added:
parse_line_width, parse_color, and parse_line_style
Additionally a few test cases were added to borders.html.
