This patch adds an IndexedProperties object for storing indexed
properties within an Object. This accomplishes two goals: indexed
properties now have an associated descriptor, and objects now gracefully
handle sparse properties.
The IndexedProperties class is a wrapper around two other classes, one
for simple indexed properties storage, and one for general indexed
property storage. Simple indexed property storage is the common-case,
and is simply a vector of properties which all have attributes of
default_attributes (writable, enumerable, and configurable).
General indexed property storage is for a collection of indexed
properties where EITHER one or more properties have attributes other
than default_attributes OR there is a property with a large index (in
particular, large is '200' or higher).
Indexed properties are now treated relatively the same as storage within
the various Object methods. Additionally, there is a custom iterator
class for IndexedProperties which makes iteration easy. The iterator
skips empty values by default, but can be configured otherwise.
Likewise, it evaluates getters by default, but can be set not to.

also add missing "#pragma once" in StylePropertiesModel.h

This seems to have a higher chance of generating somewhat recognizable
content compared to inline layout. This problem will gradually go away
as we implement more display values.

We still don't handle non-ASCII input correctly, but at least now we'll
convert e.g ISO-8859-1 to UTF-8 before starting to tokenize.
This patch also makes "view source" work with the new parser. :^)

It was getting to crowded between two Buggies and the app icon.

This adds a basic implementation of xargs.
The implemenation is missing quite a few options, and is not entirely
POSIX-compliant, but it gets the job done :^)
|
|
This commit also changes the mode parsing to allow specifying the modes
in any order.
|
|
Since the task of splitting a string via another is pretty common, we
might as well have this overload of split_view() as well.

The grub-image target no longer conflicts with normal image target.
This unbreaks using CMake with Ninja.
Fixes #2423.

This is enough to parse the Google front page! (Note: I did have to
hack the tokenizer while parsing Google, in order to avoid named
character references screwing everything up. We'll fix that too soon
enough!)

We can now parse self-closing "<img>" tags correctly! :^)
|

While we're still supporting both the old and the new parser, we have
to deal with the way they load inline stylesheet (and scripts) a bit
differently.
The old parser loads all the text content up front, and then notifies
the containing element. The new parser creates the containing element
up front and appends text inside it afterwards.
For now, we simply do an empty "children_changed" notification when
first inserting a text node inside an element. This at least prevents
the CSS parser from choking on a single-character stylesheet.

Seems like SOMEONE forgot to put a <!DOCTYPE html> on serenityos.org..
No matter, now we can handle it in the new parser! :^)
|
|
This doesn't do anything yet, but it will sooner or later. :^)
|
|
With this change, we can finally load and render welcome.html :^)

The AAA is a somewhat daunting algorithm you have to run for certain
tag when inserted inside the <body> element. The purpose of it is to
resolve issues with mismatched tags.
This patch implements the first half of the AAA. We also move the
"list of active formatting elements" to its own class, since it kept
accumulating little behaviors. "Marker" entries are now signified by
null Element pointers in the list.
|
|
This only works in some narrow cases, but should be enough for our own
welcome.html at least. :^)
|
|
You can now pass "-n" to the browser to use the new HTML parser.
It's not turned on by default since it's still very immature, but this
is a huge step towards bringing it into maturity. :^)
|
|
The console has now enabled history in its input text box. Pretty
nice to not have to retype things all the time :^)
|
|
This patch adds the ability to enable "input history" on a textbox,
allowing to navigate between the history with the arrow keys.
Also removes a custom TextBox subclass from HackStudio that added
the exact same hooks, and moves it to use the now standard ones.
|
|
I can now see Swedish letters when opening Google in the browser. :^)

Add a deferral counter and defer reflowing the visual lines until the
counter is at zero. Use this to defer reflow when inserting text.
This fixes glacial slowdown while paste large amounts of text.
|
|
This feels a lot nicer than moving the cursor to the document end.
|
|
|
|
One little step at a time towards parsing the monster blob of HTML we
get from twitter.com :^)

Stopping means the client no longer cares about the download, so we
should just forget about it in the server.

Previously, the Object class had many different types of functions for
each action. For example: get_by_index, get(PropertyName),
get(FlyString). This is a bit verbose, so these methods have been
shortened to simply use the PropertyName structure. The methods then
internally call _by_index if necessary. Note that the _by_index
have been made private to enforce this change.
Secondly, a clear distinction has been made between "putting" and
"defining" an object property. "Putting" should mean modifying a
(potentially) already existing property. This is akin to doing "a.b =
'foo'".
This implies two things about put operations:
- They will search the prototype chain for setters and call them, if
necessary.
- If no property exists with a particular key, the put operation
should create a new property with the default attributes
(configurable, writable, and enumerable).
In contrast, "defining" a property should completely overwrite any
existing value without calling setters (if that property is
configurable, of course).
Thus, all of the many JS objects have had any "put" calls changed to
"define_property" calls. Additionally, "put_native_function" and
"put_native_property" have had their "put" replaced with "define".
Finally, "put_own_property" has been made private, as all necessary
functionality should be exposed with the put and define_property
methods.
