This patch adds a[foo] and a[foo=bar] attribute selectors.
Note that an attribute selector is an optional part of a selector
component, and not a component on its own.
We were not producing the correct DOM attribute in either of those
cases. "<div attr>" would produce no attribute, and the other would
produce an attribute with null value (instead of an empty value.)
Previously they would resort based on the column immediately when you
mousedown on them. Now we track the click event and show the header
in a pressed state, etc. The usual button stuff :^)
Instead of implicitly copying whatever you select, and pasting when you
middle-click, let's have traditional copy and paste actions bound to
Ctrl+Shift+C and Ctrl+Shift+V respectively.
This code was using the text from the DOM as a reference for how much
whitespace to remove from the end of a line box.
Since the DOM may contain uncollapsed whitespace, it would sometimes
be out of sync with the collapsed text used by the rest of the layout
system.
This works for C++ syntax highlighted text documents by caching the C++
token type in a new "arbitrary data" member of GTextDocumentSpan.
When the cursor is placed immediately before a '{' or immediately after
a '}', we highlight both of these brace buddies by changing their
corresponding spans to have a different background color.
..and spans can also now have a custom background color. :^)
Instead of trying to build the host-side code generator helpers right
before we need them in the LibHTML build process, just build them ahead
of time in makeall.sh, like we already do for {IPC,Form}Compiler.
It's no longer possible to build LibHTML on the host machine since it
depends on LibGUI now. This patch gets rid of the dual Makefiles in
LibHTML since we only support Serenity builds anyway.
Also clean the code generator directory before building it.
These CSS properties constrain the computed width of a block-level box
to a maximum, followed by a minimum value.
This makes the "better mother fricken website" look more like it's
intended to (which helps makes the author's point, I suppose.)
This is a very bulky way of doing this, and doesn't seem sustainable to
implement every shorthand property this way, but it's a place to start.
The "margin" CSS property now expands into its four longhands as far as
my understanding of the specs.
Note that shorthand expansion happens when we *resolve* style, not when
we parse CSS. I'm not sure this is correct anymore, I think other UA's
may actually expand shorthands into the declaration directly at parse
these days. If so, we should do this at parsing as well.
Code for parsing and stringifying CSS properties is now generated based
on LibHTML/CSS/Properties.json
At the moment, the file tells us three things:
- The name of a property
- Its initial value
- Whether it's inherited
Also, for shorthand properties, it provides a list of all the longhand
properties it may expand too. This is not actually used in the engine
yet though.
This *finally* makes layout tree dumps show the names of CSS properties
in effect, instead of "CSS::PropertyID(32)" and such. :^)
Add an initial implementation of pthread attributes for:
* detach state (joinable, detached)
* schedule params (just priority)
* guard page size (as skeleton) (requires kernel support maybe?)
* stack size and user-provided stack location (4 or 8 MB only, must be aligned)
Add some tests too, to the thread test program.
Also, LibC: Move pthread declarations to sys/types.h, where they belong.
This can be implemented entirely in userspace by calling tcgetattr().
To avoid screwing up the syscall indexes, this patch also adds a
mechanism for removing a syscall without shifting the index of other
syscalls.
Note that ports will still have to be rebuilt after this change,
as their LibC code will try to make the isatty() syscall on startup.
Have pthread_create() allocate a stack and passing it to the kernel
instead of this work happening in the kernel. The more of this we can
do in userspace, the better.
This patch also unexposes the raw create_thread() and exit_thread()
syscalls since they are now only used by LibPthread anyway.
