This PR adds support for Outer variants of each DropDirection.
When calculating the drop direction, the cursor position is calculated
relevant to the box over which it is hovering. The following diagram
shows how drop directions are calculated. The colored in center is
currently not supported, it is assigned to the top, bottom, left, right
direction for now, though it will ultimately be its own distinct
direction.
When an outer drop direction is provided for a move operation, if the
reference node flexes in the same axis as the drop direction, the new
node will be inserted at the same level as the parent of the reference
node. If the reference node flexes in a different direction or the
reference node does not have a grandparent, the operation will fall back
to its non-Outer variant.
This also removes some chatty debug statements, adds a blur to the
currently-dragging node to indicate that it cannot be dropped onto, and
simplifies the deriving of the layout state atom from the tab atom so
there's no longer another intermediate derived atom for the layout node.
This also adds rudimentary support for rendering custom preview images
for any tile being dragged. Right now, this is a simple block containing
the block ID, but this can be anything. This resolves an issue where
letting React-DnD generate its own previews could take up to a half
second, and would block dragging until complete. For Monaco, this was
outright failing.
It also fixes an issue where the tile layout could animate on first
paint. Now, I use React Suspense to prevent the layout from displaying
until all the children have loaded.
This change passes the file name to monaco, so it can use its own
detection to determine highlighting of supported files. It also resolves
some of the mimetypes with more common use cases for a terminal.
I noticed that the display nodes weren't getting updated when the browser zoom level changed. I found that using ResizeObserver was a better mechanism to capture this signal.
I am updating the layout node setup to write to its own wave object.
The existing setup requires me to plumb the layout updates through every
time the tab gets updated, which produces a lot of annoying and
unintuitive design patterns. With this new setup, the tab object doesn't
get written to when the layout changes, only the layout object will get
written to. This prevents collisions when both the tab object and the
layout node object are getting updated, such as when a new block is
added or deleted.
This cleans up the unused/unnecessary css properties added around the
same time as the modal component. This mostly refers to variables that
started with --app. They have been removed and their uses have been
replaced with other defaults. The --warning-color and --success-color
properties still exist despite being unused since they seem to fit with
the --error-color which is already in use.
This fixes two bugs. The first had to do with the path library not
working in prod. That involved making a simple version of it that works
in the meantime. The other is rendering a different number of hooks
which required moving hooks outside of an if statement.
