* Allow EventHandler args to be partially applied
When an EventHandler is called with an incomplete set of args it creates a
partial EventSpec. This change allows Component._create_event_chain to apply
remaining args from an args_spec to an existing EventSpec to make it
functional.
Instead of requiring the use of `lambda` functions to pass arguments to an
EventHandler, they can now be passed directly and any remaining args defined in
the event trigger will be applied after those.
* [REF-2273] Implement `.setvar` special EventHandler
All State subclasses will now have a special `setvar` EventHandler which
appears in the autocomplete drop down, passes static analysis, and canbe used
to set State Vars in response to event triggers.
Before:
rx.input(value=State.a, on_change=State.set_a)
After:
rx.input(value=State.a, on_change=State.setvar("a"))
This reduces the "magic" because `setvar` is statically defined on all State
subclasses.
* Catch invalid Var names and types at compile time
* Add test cases for State.setvar
* Use a proper redis-compatible token
* test_foreach: assert on arg _var_type
* [REF-2682] Foreach over dict uses Tuple arg value
When iterating over a Var with _var_type dict, the resulting arg value
_var_type should be Tuple[key, value] so it can be correctly used with other
var operations.
Fix#3157
* Correct _var_type for iteration over Tuple of multiple types
The arg value when iterating over a tuple could be any of the possible values
mentioned in the annotation.
When only one type is used, the Union collapses to the base type, at least in py3.11
* Add comments
* pyi_generator: ignore `app.py` and single files
When running pyi_generator in pre-commit, it passes individual changed files on
the command line as targets, and these were not being properly excluded
according to the EXCLUDED_FILES list.
Add app.py to the EXCLUDED_FILES list so it does not get regenerated
automatically.
* [REF-2587] Ignore top-level theme appearance
From the Radix docs, it is not recommended to actually set `appearance`, but
instead use next-themes to set and switch the appearance dynamically.
Because Reflex already compiles the top-level theme into the next-themes
ThemeProvider, we can blank out the appearance prop after compiling contexts.js
to avoid a mismatch between the selected app appearance and the appearance in
the rx.theme when displaying overlay components.
Fix#2992
