value and bound arguments
This allows Function objects produced by Function.prototype.bind, as well
as arrow functions to track their |this| values and bound arguments.
This little tweak fixes the issue where the scrolling speeds up
significantly if the user wiggles their cursor. Just something obvious
I spotted while watching the video :^)
Previously, TextEditor processed the Select all command directly on the
keydown event handler. For this reason, WindowManager would not process
it as an action for the focused control and an action with the same
keyboard shortcut from the parent could override the TextEditor's one
even when it is focused.
For instance, when pressing Ctrl+A on the FileManager's path bar, all
files were selected instead, which is not the expected behavior.
Now the Select all command is an actual action on TextEditor, so that
WindowManager can process it correctly before any other actions. I also
added an icon for it!
If you select some text and drag the cursor outside the widget on the
left hand side, we would previously suddenly snap the selection cursor
to the end of the line instead of keeping it at the start of the line
as you would expect. This patch fixes that. :^)
If you start selecting text and move the cursor outside the TextEditor
widget area without letting go of the mouse button, we will now keep
scrolling a little bit every 100ms.
DWARF line number information, if generated, is stored in the
.debug_line section of an object file.
The information is encoded as instructions for a VM that is defined in
the DWARF specification.
By executing these instructions, we can extract the encoded line number
information.
We allow the ref-counting parts of an object to be mutated even when the
object itself is a const.
An important detail is that we allow invoking 'will_be_destroyed' and
'one_ref_left', which are not required to be const qualified, on const
objects.
Previously, drag and drop would only work when dragging between node
items on a DirectoryView. This commit makes it possible to drag files to
the empty area of the DirectoryView and copy files more easily between
windows.
This allows us to run "run-tests -g" for testing with GC after every
heap allocation. This may flush out bugs that would otherwise not
occur if GC'ing only occasionally.
A MarkedValueList is basically a Vector<JS::Value> that registers with
the Heap and makes sure that the stored values don't get GC'd.
Before this change, we were unsafely keeping Vector<JS::Value> in some
places, which is out-of-reach for the live reference finding logic
since Vector puts its elements on the heap by default.
We now pass all the JavaScript tests even when running with "js -g",
which does a GC on every heap allocation.
