On argument swapping to put positional ones toward the end,
m_arg_index was pointing at "last arg index" + "skipped args" +
"consumed args" and thus was pointing ahead of the skipped ones.
m_arg_index now points after the current parsed option arguments.
CMYK data describes which inks a printer should use to print a color.
If a screen should display a color that's supposed to look similar
to what the printer produces, it results in a color very different
to what Color::from_cmyk() produces. (It's also printer-dependent.)
There are many ICC profiles describing printing processes. It doesn't
matter too much which one we use -- most of them look somewhat
similar, and they all look dramatically better than Color::from_cmyk().
This patch adds a function to download a zip file that Adobe offers
on their web site. They even have a page for redistribution:
https://www.adobe.com/support/downloads/iccprofiles/icc_eula_win_dist.html
(That one leads to a broken download though, so this downloads the
end-user version.)
In case we have to move off this download at some point, there are also
a whole bunch of profiles at https://www.color.org/registry/index.xalter
that "may be used, embedded, exchanged, and shared without restriction".
The adobe zip contains a whole bunch of other useful and fun profiles,
so I went with it.
For now, this only unzips the USWebCoatedSWOP.icc file though, and
installs it in ${CMAKE_BINARY_DIR}/Root/res/icc/Adobe/CMYK/. In
Serenity builds, this will make it to /res/icc/Adobe/CMYK in the
disk image. And in lagom build, after #23016 this is the
lagom res staging directory that tools can install via
Core::ResourceImplementation. `pdf` and `MacPDF` already do that,
`TestPDF` now does it too.
The final piece is that LibPDF then loads the profile from there
and uses it for DeviceCMYK color conversions.
(Doing file access from the bowels of a library is a bit weird,
especially in a system that has sandboxing built in. But LibGfx does
that in FontDatabase too already, and LibPDF uses that, so it's not a
new problem.)
This way, build files can install things into
`${CMAKE_BINARY_DIR}/Root/res/` and it'll work in both serenity and
lagom builds.
It allows using a single `Core::ResourceImplementation::install()`
call to install both checked-in and generated files (as long as both
get copied into this new build-time staging dir).
No behavior change.
Many widget classes need to run substantial initialization code after
they have been setup from GML. With this change, an
initialize_fallibles() function is called if available, allowing the
initialization to be invoked from the GML setup automatically. This
means that the GML-generated creation function can now be used directly
for many more cases, and reduces code duplication.
We currently bundle AK with LibCore on Lagom. This means that to use AK,
all libraries must also depend on LibCore. This will create circular
dependencies when we create LibURL, as LibURL will depend on LibUnicode,
which will depend on LibCore, which will depend on LibURL.
This helper can automatically link against libraries needed by all
utilities, such as LibCore. This is to make extracting AK into its own
library a bit easier.
Due to the way expression parser is written, we need to resolve the
ambiguity between member access operators and dots used for punctuation
during lexing. The lexer uses a (totally bulletproof) heuristic to do
that: whenever '.' is followed by ' ' or '\n', it is considered a dot
and member access otherwise. While it works fine for prettified test
cases, non-prettified files often lack enter after a trailing dot
character. Since MemberAccess will always be invalid at that position,
explicitly treat trailing dot as a part of punctuation.
RecursiveASTVisitor was recursing into the subtrees of an old root if it
was changed in on_entry callback. Fix that by querying root pointer just
after on_entry callback returns. While on it, also use
`AK::TemporaryChange` instead of setting `m_current_subtree_pointer`
manually.
As it turns out, `FunctionCallCanonicalizationPass` was relying on being
able to replace tree on entry, and the bug in RecursiveASTVisitor made
the pass to not fully canonicalize nested function calls.
The changes to GenericASTPass.cpp alone are enough to fix the problem
but it is canonical (for some definition of canonicity) to only change
trees in on_leave. Therefore, the commit also switches
FunctionCallCanonicalizationPass to on_leave callback.
A test for this fix and one from the previous commit is also included.
We cannot handle them normally since we need text between parenthesis to
be a valid expression. As a workaround, we now push an artificial value
to stack to act as an argument (it'll be later removed during function
call canonicalization).
I got fed up with looking at error messages that tell me "VERIFICATION
FAILED: !is_error()". So this commit introduces DiagnosticEngine class
whose purpose is to accumulate and print more user-friendly errors.
For some reason I was afraid to add trivial accessors to classes
in earlier PRs, so we now have dozens of classes with public fields. I'm
not exactly looking forward to refactoring them all at once but I'll
do so gradually.
FontDatabase.h with its includes add up to quite a lot of code. In the
next commit, compiled GML files are going to need to access the
FontWeight enum, so let's allow them to do that without pulling in lots
of other things.
Also, change users to include FontWeight.h instead of FontDatabase.h
where appropriate.
This splits the RIFFTypes header/TU into the WAV specific parts, which
move to WavTypes.h, as well as the general RIFF parts which move to the
new LibRIFF.
Sidenote for the spec comments: even though they are linked from a site
that explains the WAV format, the document is the (an) overall RIFF spec
from Microsoft. A better source may be used later; the changes to the
header are as minimal as possible.
...and hook it up.
I opened MainMenu.xib in Xcode, added a new "Submenu Menu Item"
from the Library (cmd-shift-l), added a User Defined
"toggleShowClippingPaths:" action on First Responder and connected
the menu item's action to that action.
(I first tried duplicating the existing Window menu and editing that,
but the Window menu is marked as `systemMenu="window"` in the xib and
I couldn't find a way to undo that in Xcode. So the Debug menu first
acted as a second Window menu.)
I made "Debug" a toplevel menu to make it consistent with Ladybird.app
for now, but I'll probably make it a submenu of "View" in the future.
This creates a bitmap filled with a fixed color, then (in memory)
saves it as jpeg and loads it again, and repeats that until the
color of the bitmap no longer changes. It then reports how many
iterations that took, and what the final color was.
It does this for a couple of colors.
This is for quality assessment of the jpeg codec. Ideally, it should
converge quickly (in one iteration), and on a color not very far from
the original input color.
`JsonValue::to_byte_string` has peculiar type-erasure semantics which is
not usually intended. Unfortunately, it also has a very stereotypical
name which does not warn about unexpected behavior. So let's prefix it
with `deprecated_` to make new code use `as_string` if it just wants to
get string value or `serialized<StringBuilder>` if it needs to do proper
serialization.
A bunch of users used consume_specific with a constant ByteString
literal, which can be replaced by an allocation-free StringView literal.
The generic consume_while overload gains a requires clause so that
consume_specific("abc") causes a more understandable and actionable
error.
We have two known PlatformObjects that need to implement some of the
behavior of LegacyPlatformObjects to date: Window, and HTMLFormElement.
To make this not require double (or virtual) inheritance of
PlatformObject, move the behavior of LegacyPlatformObject into
PlatformObject. The selection of LegacyPlatformObject behavior is done
with a new bitfield of feature flags instead of a dozen virtual
functions that return bool. This change simplifies every class involved
in the diff with the notable exception of Window, which now needs some
ugly const casts to implement named property access.
