It's a little sad having two diferent versions of this function, but I
don't know of any better way to do it. This also gets rid of some const
casts down the line.
This saves us both a bit of time and accuracy, as Serenity's strtod()
still is a little bit off sometimes - and stringifying the result and
parsing it again just increases that offset.
Adds metadata about apps for what file types and protocols they can
handle, then consumes that in the LaunchServer. The LaunchServer can
then use that to offer multiple options for what apps can open a given
URL. Callers can then pass back the handler name to the LaunchServer to
use an alternate app :)
As these parameter-less overloads don't change the value's type and
just assume Type::Number, naming them as_i32() and as_size_t() is more
appropriate.
This patch is unfortunately rather large and might make some things feel
bloated, but it is necessary to fix a few flaws in LibJS, primarily
blindly coercing values to numbers without exception checks - i.e.
interpreter.argument(0).to_i32(); // can fail!!!
Some examples where the interpreter would actually crash:
var o = { toString: () => { throw Error() } };
+o;
o - 1;
"foo".charAt(o);
"bar".repeat(o);
To fix this, we now have the following...
to_double(Interpreter&)
to_i32()
to_i32(Interpreter&)
to_size_t()
to_size_t(Interpreter&)
...and a whole lot of exception checking.
There's intentionally no to_double(), use as_double() directly instead.
This way we still can use these convenient utility functions but don't
need to check for exceptions if we are sure the value already is a
number.
Fixes#2267.
Passing a Heap& to it only to then call interpreter() on that is weird.
Let's just give it the Interpreter& directly, like some of the other
to_something() functions.
This commit updates CLionConfiguration.md and NotesOnWSL.md so that
they comply with new build system. In addition to that, the WSL doc
is updated to include instructions to run qemu (and serenity) natively
on Windows, without needing an X-window server.
Oops, we can't be appending substrings of a string we just deleted!
Fix this by building up the new line instead of trying to clear and
append in place. This works out nicely as we now do fewer document view
updates when removing a range. :^)
Widgets can now opt in to emoji input via set_accepts_emoji_input().
If the focused widget accepts emoji input, we'll pop up a simple dialog
with all the available emojis as clickable buttons.
You can press escape if you change your mind and don't want an emoji.
This UI layout definitely will not scale as we add more emojis, but it
works for the moment, and we can adapt it as we go. Pretty cool! :^)
A TextDocumentLine is now backed by a non-null-terminated sequence of
Unicode codepoints encoded as UTF-32 (one u32 per codepoint.)
This makes it possible to view and edit arbitrary Unicode text without
strange cursor and selection behavior. You can freely copy and paste
emojis between TextEditor and Terminal now. :^)
Storing UTF-32 is quite space-inefficient, but we should be able to
use the same optimization techniques as LibVT does to reduce it in
the typical case where most text is ASCII.
There are a lot of things that can be cleaned up around this code,
but this works well enough that I'm pretty happy with it.
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.
