Implement `GDScriptTextDocument::willSaveWaitUntil` to clean up outdated documents before saving,
then update the document in `GDScriptTextDocument::didSave`.
Previously, external editing via lsp would modify the modified time of the script,
which caused the internal display of the script to not be refreshed when refocusing
the engine.
Now saving the script externally via lsp will automatically refresh the internal
display.
Removes separate `Command` key (use `Meta` instead).
Adds an event flag to automatically remap `Command` <-> `Control` (cannot be set alongside `Control` or `Meta`).
This reverts commit 4b817a565c.
Fixes#64988.
Fixes#64997.
This caused several regressions (#64988, #64997,
https://github.com/godotengine/godot/issues/64997#issuecomment-1229970605)
which point at a flaw in the current logic:
- `Control::NOTIFICATION_ENTER_TREE` triggers a *deferred* notification with
`NOTIFCATION_THEME_CHANGED` as introduced in #62845.
- Some classes use their `THEME_CHANGED` to cache theme items in
member variables (e.g. `style_normal`, etc.), and use those member
variables in `ENTER_TREE`, `READY`, `DRAW`, etc. Since the `THEME_CHANGE`
notification is now deferred, they end up accessing invalid state and this
can lead to not applying theme properly (e.g. for EditorHelp) or crashing
(e.g. for EditorLog or CodeEdit).
So we need to go back to the drawing board and see if `THEME_CHANGED` can be
called earlier so that the previous logic still works?
Or can we refactor all engine code to make sure that:
- `ENTER_TREE` and similar do not depend on theme properties cached in member
variables.
- Or `THEME_CHANGE` does trigger a general UI update to make sure that any
bad theme handling in `ENTER_TREE` and co. gets fixed when `THEME_CHANGE`
does arrive for the first time. But that means having a temporary invalid
(and possibly still crashing) state, and doing some computations twice
which might be heavy (e.g. `EditorHelp::_update_doc()`).
As announced in https://godotengine.org/article/godot-4-will-discontinue-visual-scripting,
Godot maintainers have agreed to discontinue the current implementation of
our VisualScript language.
The way it had been designed was not user-friendly enough and we did not
succeed in improving its usability to actually make it a good low-code
solution for users who need one.
So we prefer to remove it for Godot 4.0 and leave the door open for new,
innovative ideas around visual scripting, to be developed as plugins or
extensions now that Godot provides sufficient functionality for this
(notably via GDExtension and the godot-cpp C++ bindings).
The current module has been moved to a dedicated repository (with full Git
history extracted with `git filter-branch`):
https://github.com/godotengine/godot-visual-script
It can still be compiled as a C++ module (for now, but will likely require
work to be kept in sync with the engine repository), but our hope is that
contributors will port it to GDExtension (which is quite compatibile with
the existing C++ module code when using the godot-cpp C++ bindings).
* Shader editor is permanent (no longer transient).
* Can edit multiple files at the same time.
Likely fixes many usability issues (please lend me a hand Bugsquad team to identify them).
