The former automatically adapts the prefix to binary and octal
output, and is what we already use in the majority of cases.

I ran it 4 times (until it stopped changing things) since each
invocation only converted one instance per line.
No behavior change.
We currently support optional integral types, but not nullable types. So
if an IDL contains e.g. "long?", passing null will be coerced to 0.
This will be used by the Inspector, but will also eventually be used by
real IDL interfaces (e.g. HTMLInputElement's selectionStart).
This can apply to optional, nullable parameters of platform types. This
will cause the generator to generate the type as
Optional<JS::GCPtr<T>> rather than JS::GCPtr<T>, allowing the
implementation to differentiate between the case where the argument was
not passed, and the case where null or undefined was passed.
Needing to differentiate these two cases is quite niche, hence why it is
an opt-in behavior.
This is a simple extension of GenericLexer, and is used in more than
just LibXML, so let's move it into AK.
The move also resolves a FIXME, which is removed in this commit.
Instead of limiting ourselves to the key of the property in the JSON,
allow overriding the function name so we can generate completely
different function signatures with very similar names to other existing
API methods (e.g. `glUniform*` vs `glUniform*v`).
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.
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.
`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.
