Due to us using size_t for the length, the actual value will always be positive.
If, for example, we calculate the length as "0 - 1", we'll get SIZE_T_MAX. What
we can do is check that adding the characters pointer and the length together
doesn't overflow.
And switch the two-argument version of Checked::multiplication_would_overflow()
to use __builtin_mul_overflow_p(). This helps GCC optimize the code better.
In TabWidgets with the "uniform tabs" mode on, we will now scale tabs
between a minimum and maximum size, distributing the available space.
Partially addresses #1971.
This patchset fixes incorrect handling of escaped tokens (`a\ b`) in
Shell autocompletion and LibLine.
The users of LibLine can now choose between two token splitting modes,
either taking into account escapes, or ignoring them.
Instead of having fprintf()s all over the place we can now use
syntax_error("message") or syntax_error("message", line, column).
This takes care of a consistent format, appending a newline and getting
the line number and column of the current token if the last two params
are omitted.
It's not always safe to access pixel data of a window's backing store
since the kernel may decide to purge it at his leisure. Fix this by
instead picking colors from the color spectrum bitmap directly instead.
Also fix up mouse event logic while we're here so it only cares about
the left mouse button
Fixes#1657.
I.e. they don't require the |this| value to be a string object and
"can be transferred to other kinds of objects for use as a method" as
the spec describes it.
This commit introduces a way to get an object's own properties in the
correct order. The "correct order" for JS object properties is first all
array-like index properties (numeric keys) sorted by insertion order,
followed by all string properties sorted by insertion order.
Objects also now print correctly in the repl! Before this commit:
courage ~/js-tests $ js
> ({ foo: 1, bar: 2, baz: 3 })
{ bar: 2, foo: 1, baz: 3 }
After:
courage ~/js-tests $ js
> ({ foo: 1, bar: 2, baz: 3 })
{ foo: 1, bar: 2, baz: 3 }
You can now enter a specific color as #rrggbb instead of clicking your
way through the color picker.
If you still want the color picker, just click the little color rect in
the widget and we'll bring up a ColorPicker. For a visual cue that this
rect is interactive, we use a hover hand cursor when hovering the rect.
