In order to actually view the web as it is, we're gonna need a proper
HTML parser. So let's build one!
This patch introduces the Web::HTMLTokenizer class, which currently
operates on a StringView input stream where it fetches (ASCII only atm)
codepoints and tokenizes acccording to the HTML spec tokenization algo.
The tokenizer state machine looks a bit weird but is written in a way
that tries to mimic the spec as closely as possible, in order to make
development easier and bugs less likely.
This initial version is far from finished, but it can parse a trivial
document with a DOCTYPE and open/close tags. :^)
Adds metadata about apps for what file types and protocols they can
handle, then consumes that in the LaunchServer. The LaunchServer can
then use that to offer multiple options for what apps can open a given
URL. Callers can then pass back the handler name to the LaunchServer to
use an alternate app :)
This is not simply an inversion of the Slightly Smiling Face emoji.
The facial features were flipped vertically but the underlying "face"
was kept the same, because for both emojis the top is lighter than the
bottom.
It will listen for clipboard content changes in the backgroud. Once you click
on its icon, it will pop up a window listing all recorded clipboard contents.
You can then double-click on an item to copy it again.
This commit moves the clipboard from WindowServer into a new Clipboard
service program. Clipboard runs as the unprivileged "clipboard" user
and with a much tighter pledge than WindowServer.
To keep things working as before, all GUI::Application users now make
a connection to Clipboard after making the connection to WindowServer.
It could be interesting to connect to Clipboard on demand, but right
now that would necessitate expanding every GUI app's pledge to include
"unix" and also unveiling the clipboard portal, which I prefer not to.
Many properties can now have percentage values that get resolved in
layout. The reference value (what is this a percentage *of*?) differs
per property, so I've added a helper where you provide a reference
value as an added parameter to the existing length_or_fallback().
