The documentation is very loud about cell-based things being
deprecated, but it's fairly hidden what to actually do to switch to
the non-deprecated way (implement a certain delegate method).
Session 120 from WWDC 2011 has some notes on this. Apple's official
site no longer seems to have that, but it's e.g. here:
https://docs.huihoo.com/apple/wwdc/2011/session_120__view_based_nstableview.pdf
Just setting headerView to nil removes the header, but also has
the effect of no longer drawing the outline view with a sidebar
background ¯\_(ツ)_/¯.
But also setting drawsBackground to NO on the scroll view restores
the sidebar look, so do that too.
With this, it is no longer necessar to explicitly set style.
The default NSTableViewStyleAutomatic now seems to resolve to
NSTableViewStyleSourceList, so stop explicitly setting it.
(This part has no behavior change.)
Clicking an item in the outline now opens that page.
This requires giving the outline view a delegate, which for some
reason also has th effect of indenting expandable items ¯\_(ツ)_/¯
The vertical alignment of text still looks off, though.
The outline has drawing artifacts, but it is somewhat functional:
You can click on disclosure triangles to open outline items, and
if the outline doesn't fit in the sidebar, it's scrollable.
The outline view has the correct sidebar look: gray with a slightly
transparent glass effect.
Clicking items doesn't have an effect yet.
Previously, `load_from_memory()` just took a raw pointer to the data,
and then manually calculated offsets from that pointer. Instead, let's
use the MappedFile we already have, to stream in the data, to make
things a bit safer. We also now check that the entire file's data was
read, since if there was data left over, then either the file is bad or
we've done something wrong.
I've moved the code directly into `try_load_from_mapped_file()` since
`load_from_memory()` was only called from there. The extra indirection
wasn't adding anything.
When working with FixedMemoryStreams, and especially MappedFiles, you
may don't want to copy the underlying data when you read from the
stream. Pointing into that data is perfectly fine as long as you know
the lifetime of it is long enough.
This commit adds a couple of methods for reading either a single value,
or a span of them, in this way. As noted, for single values you sadly
get a raw pointer instead of a reference, but that's the only option
right now.
GitHub allows relative paths to be used to display images, this should
make the image continue working even when viewing the README from an
earlier commit of the repo in case the location of screenshots is moved.
This is also just a cleaner way to do this.
Turns out this was hurting performance instead of helping it.
By removing the inline capacity, we shrink the size of ExecutionContext
by 512 bytes, which substantially reduces the stack pressure created by
JS recursion (each call creates a new ExecutionContext on the stack).
4.4% speed-up on the entire Kraken benchmark :^)
Previously every file that included Executable.h (which is pretty much
most LibJS and LibHTML files, given that VM.h needs it) had the whole
definition of LibRegex, which was slowing down source parsing.
Window.h is a rather heavy file, so let's try not to include it in
header files when we can!
Element.h now also includes LibWeb/Bindings/Intrinsics.h, but that's
just out of my laziness. Most if not all objects call
`Bindings::ensure_web_prototype<>()` anyway, so I don't think we would
gain much by sticking the header to source files instead.
We needed to keep the old versions of these functions around before all
of the IDL interfaces were ported over to new AK String, but now that is
done, we can remove the deprecated versions of these functions.
When we hit the cache in GetGlobal, we don't need the identifier string
at all, so let's defer fetching it until after the cache miss.
7% speed-up on Kraken/imaging-gaussian-blur.js :^)
We were incorrectly offsetting the static position of abspos children of
flex containers by the padding twice. This was a misguided attempt to
adjust to the abspos containing block being the padding box, not the
content box.
Fixes#21344.
Also remove the hack for SVG documents, a well-formed SVG document has
the correct xmlns attribute set, which should be automatically picked up
by the builder now.
If we have a cached environment coordinate that hasn't been screwed
by eval(), we can get the value directly without instantiating a
Reference.
15% speed-up on Octane/zlib.js :^)
