Here a little refactored copy paste instance plugin.
Now we copy all data including slots and tokens though paste write them
as is or do not write at all if already exist.
This let us to not do unnecessary patches for copy paste within project
while still have whole UI pasted in different project.
There is still a problem with pasting styles which always have different
breakpoint ids in each project. We will need to implement merging in
other PR.
Ref https://github.com/webstudio-is/webstudio-builder/issues/1116
Slot is copy pastable part of the tree which is always in sync. Kinda
like primitive components.
The idea is the following. Slot is copy pasted as any other instance
though its children are preserved as is without cloning with new ids.
This lead to the problem with multiple slot children. While copy paste
they are preserved as is though when add new child to slot, the other
instance of it will not get new child.
To workaround this we add another Fragment component which groups all
children into single one and new children are always reflected in all
slot copies.
- in many places root check can be replaced with selector.length === 1
- reparent and insert utilities now accept selectors
- findClosestDroppableTarget output end instead of last index and always
fallback to root
With slots there can be same ids in one tree so we need new way to
address instances. Here I propose the list from target instance to the
root.
Now instead of computing parents by normalized tree (one instance of
slot can have many parents) we just access already computed list from
rendered tree.
This address can be computed when user click in dom which can be
traversed or it can be passed top-down with props.
The main con of this approach is collaboration. Reparanted instances on
by one user makes "selected address" stale. Though we have similar
situation with single id when instance is deleted.
Isolated mode for slots/components will make this problem less
noticable.
Need to cleanup all page related data to prevent bloating project with
garbage data. Delete already prevent reloading so its safe to clear data
on client.
## Description
This effectively is the beginning of copy/paste plugin system. Now
instance copy paste is a plugin that is fully encapsulated and we can
add more of them
## Steps for reproduction
1. copy/paste instances on the same page
2. copy/paste instances across pages
3. copy paste across projects
## Code Review
- [ ] hi @TrySound , I need you to do
- conceptual review (architecture, feature-correctness)
- detailed review (read every line)
- test it on preview
## Before requesting a review
- [ ] made a self-review
- [ ] added inline comments where things may be not obvious (the "why",
not "what")
## Before merging
- [ ] tested locally and on preview environment (preview dev login:
5de6)
- [ ] updated [test
cases](https://github.com/webstudio-is/webstudio-builder/blob/main/apps/builder/docs/test-cases.md)
document
- [ ] added tests
- [ ] if any new env variables are added, added them to `.env.example`
and the `builder/env-check.js` if mandatory
