This commit adds the following classes: SymbolObject, SymbolConstructor,
SymbolPrototype, and Symbol. This commit does not introduce any
new functionality to the Object class, so they cannot be used as
property keys in objects.
To conserve memory, we now use byte storage for terminal lines until we
encounter a non-ASCII codepoint. At that point, we transparently switch
to UTF-32 storage for that one line.
This fixes an issue where continuously posting new events to the queue
would keep the event loop saturated, causing it to ignore notifiers.
Since notifiers are part of the big select(), we always have to call
wait_for_events() even if there are pending events. We're already smart
enough to select() without a timeout if we already have pending events.
Instead of relying on the GUI code to handle UTF-8, we now process
and parse the incoming data into 32-bit codepoints ourselves.
This means that you can now show emojis in the terminal and they will
only take up one character cell each. :^)
This was supposed to be the foundation for some kind of pre-kernel
environment, but nobody is working on it right now, so let's move
everything back into the kernel and remove all the confusion.
We stopped using gettimeofday() in Core::EventLoop a while back,
in favor of clock_gettime() for monotonic time.
Maintaining an optimization for a syscall we're not using doesn't make
a lot of sense, so let's go back to the old-style sys$gettimeofday().
Store the offset in the string table for the DT_SONAME entry. Now that
the build uses cmake, cmake is helpfully passing --Wl,-soname to the
linker for shared objects. This makes the LinkDemo run again.
We will now actually use MIME types for clipboard. The default type is now
"text/plain" (instead of just "text").
This also fixes some issues in copy(1) and paste(1).
There are now two API's on Value:
- Value::to_string(Interpreter&) -- may throw.
- Value::to_string_without_side_effects() -- will never throw.
These are some pretty big sweeping changes, so it's possible that I did
some part the wrong way. We'll work it out as we go. :^)
Fixes#2123.
Rather than printing them to stderr directly the parser now keeps a
Vector<Error>, which allows the "owner" of the parser to consume them
individually after parsing.
The Error struct has a message, line number, column number and a
to_string() helper function to format this information into a meaningful
error message.
The Function() constructor will now include an error message when
throwing a SyntaxError.
Giving the lexer the ability to generate errors adds unnecessary
complexity - also it only calls its syntax_error() function in one place
anyway ("unterminated string literal"). But since the lexer *also* emits
tokens like Eof or UnterminatedStringLiteral, it should be up to the
consumer of these tokens to decide what to do.
Also remove the option to not print errors to stderr as that's not
relevant anymore.
This commit moves the clipboard from WindowServer into a new Clipboard
service program. Clipboard runs as the unprivileged "clipboard" user
and with a much tighter pledge than WindowServer.
To keep things working as before, all GUI::Application users now make
a connection to Clipboard after making the connection to WindowServer.
It could be interesting to connect to Clipboard on demand, but right
now that would necessitate expanding every GUI app's pledge to include
"unix" and also unveiling the clipboard portal, which I prefer not to.
The header is essentially just a commented + annotated version of both
the Itanium Exception Handling ABI Level I, and the 386-specific
SystemV ABI for the same. Wrapping one's head around the spec is half
the work :^)
