The check for invalid lhs and assignment to eval/arguments in strict
mode should happen for all kinds of assignment expressions, not just
AssignmentOp::Assignment.
So far we have three different syntax highlighters for LibJS:
- js's Line::Editor stylization
- JS::MarkupGenerator
- GUI::JSSyntaxHighlighter
This not only caused repetition of most token types in each highlighter
but also a lot of inconsistency regarding the styling of certain tokens:
- JSSyntaxHighlighter was considering TokenType::Period to be an
operator whereas MarkupGenerator categorized it as punctuation.
- MarkupGenerator was considering TokenType::{Break,Case,Continue,
Default,Switch,With} control keywords whereas JSSyntaxHighlighter just
disregarded them
- MarkupGenerator considered some future reserved keywords invalid and
others not. JSSyntaxHighlighter and js disregarded most
Adding a new token type meant adding it to ENUMERATE_JS_TOKENS as well
as each individual highlighter's switch/case construct.
I added a TokenCategory enum, and each TokenType is now associated to a
certain category, which the syntax highlighters then can use for styling
rather than operating on the token type directly. This also makes
changing a token's category everywhere easier, should we need to do that
(e.g. I decided to make TokenType::{Period,QuestionMarkPeriod}
TokenCategory::Operator for now, but we might want to change them to
Punctuation.
This would previously fail at runtime, and it would have zero indication
of what exactly went wrong.
Also adds `AK::DependentFalse<Ts...>', which is a...dependent false.
There's no point in trying to achieve shape sharing for global objects,
so we can simply make the shape unique from the start and avoid making
a transition chain.
Previously whenever you would ask a Shape how many properties it had,
it would reify the property table into a HashMap and use HashMap::size()
to answer the question.
This can be a huge waste of time if we don't need the property table for
anything else, so this patch implements property count tracking in a
separate integer member of Shape. :^)
Since blocks can't be strict by themselves, it makes no sense for them
to store whether or not they are strict. Strict-ness is now stored in
the Program and FunctionNode ASTNodes. Fixes issue #3641
Skip over invisible children so they don't take up vertical space in
the container. Also make sure we update the preferred size whenever the
widget layout is invalidated.
Fixes#3139.
When the user right-clicks on an image, you might want to show a
special context menu, separate from the regular link context menu.
This patch only implements enough of the functionality to get this
working in a single-process context.
If we're sharing buffers, we only want to share trivial structures
as anything else could potentially share internal pointers, which
most likely is going to cause problems due to different address
spaces.
Fix the GUI::SystemTheme structure, which was not trivial, which
is now caught at compile time.
Fixes#3650
When scanning for potential heap pointers during conservative GC,
we look for any value that is an address somewhere inside a heap cell.
However, we were failing to account for the slack at the end of a
block (which occurs whenever the block storage size isn't an exact
multiple of the cell size.) Pointers inside the trailing slack were
misidentified as pointers into "last_cell+1".
Instead of skipping over them, we would treat this garbage data as a
live cell and try to mark it. I believe this is the test-js crash that
has been terrorizing Travis for a while. :^)
Editors now communicate with the c++ language server when openning and
editing c++ source files, and go through the language server to get
autocomplete suggestions.
The language server keeps track of the content of currently edited
files by receiving updates about edit actions.
Also, C++ autocompletion is no longer tied to HackStudio itself and
moved to be part of the language server.
Each JS global object has its own "console", so it makes more sense to
store it in GlobalObject.
We'll need some smartness later to bundle up console messages from all
the different frames that make up a page later, but this works for now.
