Iwo PlazaandFacebook GitHub Bot 156ee5bee7 Migrate StyleSheet/processColorArray.js to use export syntax (#48905)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/48905

## Motivation
Modernising the react-native codebase to allow for ingestion by modern Flow tooling.

## This diff
- Updates `Libraries/StyleSheet/processColorArray.js` to use `export` syntax.
- Appends `.default` to requires of the changed files.
- Updates test files.
- Updated View Config codegen (requires an MSDK bump).
- Updates the public API snapshot *(intented breaking change)*

Changelog:
[General][Breaking] - Files inside `Libraries/Text`, `Libraries/Share` and `Libraries/Settings` use `export` syntax, which requires the addition of `.default` when imported with the CJS `require` syntax.

Iwo PlazaandFacebook GitHub Bot e4d969a4ab Migrate StyleSheet/*.js to use export statements (#48609)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/48609

# Motivation
This is an attempt at modernizing the export syntax in some of the files in `Libraries/StyleSheet/`. It will allow these files to get properly ingested by modern Flow tooling.

# This diff
- Migrates the use of `module.exports` into `export default` for files located in `Libraries/StyleSheet/*.js`. Some files were omitted due to ballooning complexity, but will be addressed in other Diffs.
- Updating internal *require*s to use ".default", no product code seems to be affected.
- Migrating `require`s into `import`s where applicable, taking into account the performance implications (context: https://fb.workplace.com/groups/react.technologies.discussions/permalink/3638114866420225/)
- Updates the current iteration of API snapshots (intended).
- Updates `react-native-codegen`'s require of processColorArray, analogous to D42346452.

Changelog:
[General][Breaking] - Deep imports from some files in `StyleSheet/` can break when using the `require()` syntax, but can be easily fixed by appending `.default`

Eli WhiteandFacebook GitHub Bot 25c673e357 Fixing schema types for component command params of Arrays (#48476)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/48476

Command param array types were generating invalid schemas due to untyped parser code. The invalid schemas occurred for any alias type, including custom objects and basics like Int32. This was also inconsistent between Flow and TypeScript.

We already had one component utilizing this issue, so this just codifies that support into the schema so it reflects reality. This is only a partial solution. The more full solution would be to fully encode the custom types in the schemas like we do for Native Modules.

# More Information:

Tl;dr, DebuggingOverlay is abusing a FlowFixMe in codegen commands.

## The problem:

The [CodegenSchema](https://www.internalfb.com/code/fbsource/[d3ab2f79b377]/xplat/js/react-native-github/packages/react-native-codegen/src/CodegenSchema.js?lines=220) should be the source of truth for anything that can be in the schema. If something is in the schema that isn't allowed by the types, that's a bug. We have a bug. I'm adding compat-check support for components and it's blowing up on prod schemas because DebuggingOverlay causes an invalid schema.

## The details:

Support for Arrays as arguments in commands was added to the Codegen in D51866557. [Code Pointer](https://fburl.com/code/8yy1rm0p)

The intention appears to be to support arrays of primitives. There is a TODO for supporting complex types.

```
interface NativeCommands {
  +addOverlays: (
    viewRef: React.ElementRef<NativeType>,
    overlayColorsReadOnly: $ReadOnlyArray<string>,
  )
}
```

This support was added to TypeScript in D52046165 where it types the allowed Array arguments to be only

```
{
    readonly type: 'ArrayTypeAnnotation';
    readonly elementType:
    | Int32TypeAnnotation
    | DoubleTypeAnnotation
    | FloatTypeAnnotation
    | BooleanTypeAnnotation
    | StringTypeAnnotation
  };
```

However, because the Parsers are treating the input type as `any`, it isn't safe to pass through an input value into the schema as Flow won't catch mismatches.

The Flow parser just passes it through:

```
{
    type: 'ArrayTypeAnnotation',
    elementType: {
    // TODO: T172453752 support complex type annotation for array element
    type: paramValue.typeParameters.params[0].type,
}
```

Whereas the TypeScript parser has the more correct behavior of validating the inputs and returning specific outputs. Unfortunately, the return type is also typed here as $FlowFixMe, losing most of the benefits.

```
function getPrimitiveTypeAnnotation(type: string): $FlowFixMe {
  switch (type) {
    case 'Int32':
      return {
        type: 'Int32TypeAnnotation',
      };
    case 'Double':
      return {
        type: 'DoubleTypeAnnotation',
      };
    case 'Float':
      return {
        type: 'FloatTypeAnnotation',
      };
    case 'TSBooleanKeyword':
      return {
        type: 'BooleanTypeAnnotation',
      };
    case 'Stringish':
    case 'TSStringKeyword':
      return {
        type: 'StringTypeAnnotation',
      };
    default:
      throw new Error(`Unknown primitive type "${type}"`);
  }
}
```

[DebuggingOverlay](https://fburl.com/code/zfe3ipq7) is abusing this gap in the Flow parser by sticking an Array of Objects in.

```
export type ElementRectangle = {
  x: number,
  y: number,
  width: number,
  height: number,
};

...
  +highlightElements: (
    viewRef: React.ElementRef<DebuggingOverlayNativeComponentType>,
    elements: $ReadOnlyArray<ElementRectangle>,
  ) => void;
...
```

This isn't allowed in the schema, but it seems to fall through the holes of the flow parser and generators.

The resulting schema from Flow is this. Note the GenericTypeAnnotation which isn't allowed to be in the schema.

```
{
    "name": "highlightElements",
    "optional": false,
    "typeAnnotation": {
    "type": "FunctionTypeAnnotation",
    "params": [
        {
            "name": "elements",
            "optional": false,
            "typeAnnotation": {
                "type": "ArrayTypeAnnotation",
                "elementType": {
                    "type": "GenericTypeAnnotation"
                }
            }
        }
    ],
    "returnTypeAnnotation": {
        "type": "VoidTypeAnnotation"
    }
},
```

The TypeScript parser fails with `Error: Unsupported type annotation: GenericTypeAnnotation`.

The generators don't seem to check beyond the ArrayTypeAnnotation so they fall through to generating generic arrays.

```
// ios
elements:(const NSArray *)elements

// android
ReadableArray locations
```

## So how do I fix this?

I think there are a couple of different options here. The key problem is that the Schema types need to represent reality of what can be in the schema.

1. We revert DebuggingOverlay to not use features that aren't supported (I assume nobody would be happy with this, but the change shouldn't have been made in the first place)
2. **(This is the approach taken in this diff)** We add MixedTypeAnnotation to the allowed types in Command arrays and have it generate that and add official support for that to the TypeScript parser as well. That is probably the quickest and easiest approach. It leaves the same type unsafety we have today on the native side.
3. NativeModules seem to have a lot more complex type safety here. They persist the alias type in the schema so that the CompatCheck can check them on changes. And then in C++ they generate structs and RCTConvert functions although for Java and ObjC it looks like they just use the same untyped native code. The matching approach here would be to add `aliasMap` and the whole data to the schema for commands, use that for the compat check, and still generate the same unsafe native code.

```
export type ObjectAlias = {|
  x: number,
  y: number,
|};

export interface Spec extends TurboModule {
  +getAlias: (a: ObjectAlias) => string;
}
```

stores the ObjectAlias in the schema

```
{
  "aliasMap": {
    "ObjectAlias": {
      "type": "ObjectTypeAnnotation",
      "properties": [
        {
          "name": "x",
          "optional": false,
          "typeAnnotation": {
            "type": "NumberTypeAnnotation"
          }
        },
        {
          "name": "y",
          "optional": false,
          "typeAnnotation": {
            "type": "NumberTypeAnnotation"
          }
        },
      ]
    }
  },
  "spec": {
    "methods": [
      {
        "name": "getAlias",
        "optional": false,
        "typeAnnotation": {
          "type": "FunctionTypeAnnotation",
          "returnTypeAnnotation": {
            "type": "StringTypeAnnotation"
          },
          "params": [
            {
              "name": "a",
              "optional": false,
              "typeAnnotation": {
                "type": "TypeAliasTypeAnnotation",
                "name": "ObjectAlias"
              }
            }
          ]
        }
      }
    ]
  }
}
```

and then generates the appropriate structs on the native side and generates [this](https://www.internalfb.com/code/fbsource/[d3ab2f79b377]/xplat/js/react-native-github/packages/react-native-codegen/src/generators/modules/__tests__/__snapshots__/GenerateModuleHObjCpp-test.js.snap?lines=818)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/48343

components store unions as 'StringEnumTypeAnnotation' even though it isn't actually a union, it's a literal.

Native Modules store these as 'StringLiteralTypeAnnotation' so this converges those and reuses the same types.

Tom Van LaerhovenandFacebook GitHub Bot 13780126d3 Fix generated EventEmitter code for nested objects in arrays. (#47514)
Summary:
This PR fixes the code for generating EventEmitter C++ code in case nested objects in arrays are used.

```typescript
export interface NativeProps extends ViewProps {
  onEvent: DirectEventHandler<
    Readonly<{
      payloadArray: Readonly<
        {
          obj: Readonly<{ str: string }>
        }[]
      >
    }>
  >;
}

export default codegenNativeComponent<NativeProps>('SomeComponent');
```

In this case the generated `EventEmitters.cpp` code would contain:

```c
obj.setProperty(runtime, "str", payloadArrayValue,obj.str);
```

while

```c
obj.setProperty(runtime, "str", payloadArrayValue.obj.str);
```

is expected.

Nick GerlemanandFacebook GitHub Bot 7fb3d830be Breaking: Remove BaseViewManagerInterface (#46809)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/46809

BaseViewManagerInterface isn't adding much value right now. It was added in D16984121 to allow codegen generated ViewManager delegates to apply to view managers which derive from ViewMangager instead of BaseViewManager (if they did some cleverness, to make VM delegate apply to a no-op class, still implementing all of BaseViewManager's methods).

All of the cases where that was used have since been moved to `SimpleViewManager`, and `BaseViewManagerAdapter` (needed to wire this together) doesn't exist anymore, so it's not possible to take any advantage of this interface existing. We should remove it, since its existence  is a source of error (e.g. it was missing setters for `accessibilityValue` or those related to pointer events), and is more generally confusing for anyone adding to `BaseViewManager` in the future.

This is a breaking change, because there are some libraries which vendor a copy of generated ViewManagerDelegate when building against legacy arch to be able to share code normally generated at build time. That means these will need to be updated to maintain compatibility with RN versions of 0.77+ with new arch disabled. This will not effect compatibility of these libraries against the default new arch, and the updated delegate is still compatible with older RN version.

```
    sourceSets.main {
        java {
            if (!isNewArchitectureEnabled()) {
                srcDirs += [

Alan LeeandFacebook GitHub Bot 639d890dff add missing struct member initialization in Props.h (#44294)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/44294

**Problem:**

It was discovered while testing 3 party library, generated member variables in a C++ `struct` in `Props.h` is not initialized.
Also `WithDefault` would not work as well.
(For the problematic case it was a `boolean` but would also apply to other primitive types.)

If there is no default initialization and the component prop is optional and the user of the native component does not set the prop then the variable is never initialized and this is problematic for primitive types in C++ where no initialization results in an undefined behavior.

**Proposed solution:**

(Following C++Core Guideline of [always initialize](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Res-always).)
Reusing `generatePropsString()` used by `ClassTemplate` to generate props for `StructTemplate` as well.
updated relevant test snapshots.
This change is only concerning the `Props.h` file.

**Changelog:**
[General][Fixed] - fixed `Props.h` created from codegen missing default initializers in C++ `struct`

Dmitry RykunandFacebook GitHub Bot 6974697b04 Use paperTopLevelNameDeprecated in generated EventEmitters if defined (#42812)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/42812

There is a way of defining events where you specify additional string type parameter in the EventHandler in the spec. This additional type parameter is an overridden top level event name, that can be completely unrelated to the event handler name.
More context here D16042065.

Let's say we have
```
onLegacyStyleEvent?: ?BubblingEventHandler<LegacyStyleEvent, 'alternativeLegacyName'>
```
This will produce the following entry in the view config:
```
topAlternativeLegacyName: {
  phasedRegistrationNames: {
    captured: 'onLegacyStyleEventCapture',
    bubbled: 'onLegacyStyleEvent'
  }
}
```
This means that React expects `topAlternativeLegacyName`.
But the generated EventEmitter looks like this:
```
void RNTMyNativeViewEventEmitter::onLegacyStyleEvent(OnLegacyStyleEvent $event) const {
  dispatchEvent("legacyStyleEvent", [$event=std::move($event)](jsi::Runtime &runtime) {
    auto $payload = jsi::Object(runtime);
    $payload.setProperty(runtime, "string", $event.string);
    return $payload;
  });
}
```
The native component will emit `legacyStyleEvent` (`topLegacyStyleEvent` after normalization) that React will not be able to handle.

This issue only happens on iOS because Android doesn't use EventEmitter currently.

To address this issue we'll use `paperTopLevelNameDeprecated` for the generated EventEmitters if it is defined.

Ramanpreet NaraandFacebook GitHub Bot 3582f43440 Fix relative includes in component codegen (#42956)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/42956

In the component codegen system, when the header prefix is an empty string, we generate includes using angle brackets, like this:

```
#include <EventEmitter.h>
```

This fails to compile in buck.

If we instead generate includes using quotations, buck compiles again.
```
#include "EventEmitter.h"
```

So, changes: if the headerPrefix is an empty string, generate includes using quotes.

This is a followup to D51811596.

Dmitry RykunandFacebook GitHub Bot b32c6c2cc1 Event name normalization (#42586)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/42586

Every event name must be normalized.

The normalization strategy is:
1. If it starts with `top` -> do nothing.
2. If it starts with `on` -> replace `on` with `top`.
3. Else -> capitalize the first character and prepend `top`.

We have it for the old renderer on iOS [here](https://github.com/facebook/react-native/blob/a7586947d719a9cd2344ad346d271e7ca900de87/packages/react-native/React/Base/RCTEventDispatcher.m#L12-L21). This one is also used by the interop layer.
Static ViewConfigs being a part of the new renderer [replicate](https://github.com/facebook/react-native/blob/a7586947d719a9cd2344ad346d271e7ca900de87/packages/react-native-codegen/src/generators/components/GenerateViewConfigJs.js#L164-L172) this behavior to match the old rendered.

The Android that we have is incomplete, it is missing the [*2. If it starts with `on` -> replace `on` with `top`*]. This means that some events names that worked with the old renderer would not be compatible with the new renderer + Static ViewConfigs. Specifically every event names that start with `on`.

This diff implements event name normalization on Android.

Oskar KwaśniewskiandFacebook GitHub Bot ebb2b9c3fc feat: make codegen take OOT Apple platforms into account (#42047)
Summary:
### The problem

1. We have a library that's supported on iOS but doesn't have support for visionOS.
2. We run pod install
3. Codegen runs and generates Code for this library and tries to reference library class in `RCTThirdPartyFabricComponentsProvider`
4. Example:

```objc
Class<RCTComponentViewProtocol> RNCSafeAreaProviderCls(void) __attribute__((used)); // 0
```

This is an issue because the library files are not linked for visionOS platform (because code is linked only for iOS due to pod supporting only iOS).

### Solution

Make codegen take Apple OOT platforms into account by adding compiler macros if the given platform doesn't explicitly support this platform in the native package's podspec file.

Example generated output for library supporting only `ios` and `visionos` in podspec:

![CleanShot 2023-12-22 at 15 48 22@2x](https://github.com/facebook/react-native/assets/52801365/0cdfe7f5-441d-4466-8713-5f65feef26e7)

I used compiler conditionals because not every platform works the same, and if in the future let's say react-native-visionos were merged upstream compiler conditionals would still work.

Also tvOS uses Xcode targets to differentiate which platform it builds so conditionally adding things to the generated file wouldn't work.

## Changelog:

[IOS] [ADDED] - make codegen take OOT Apple platforms into account

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/42259

At the end of last year, we reduce build fragmentation in iOS making sure that we were always building both architecture.
In the process, we break the semantic od RCt_NEW_ARCH_ENABLED flag, making several libs stop working in one of the two archs.

This change should restore the semantic, so libraries that were using RCT_NEW_ARCH_ENABLED to run conditional code will still work in the same way. While doing so, I also removed the new USE_NEW_ARCH as we don't want unnecessary flags

Dmitry RykunandFacebook GitHub Bot dae4a11e90 Introduce "headerPrefix" codegen option (#41956)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/41956

By default, generated Cxx sources for components all end up in same directory. However the include declarations in them look like this:
```
#include <react/renderer/components/${libraryName}/ShadowNodes.h>
```
And not like this:
```
#include "ShadowNodes.h"
```
This works fine with Buck because it supports header prefixes.
To get this working with CocoaPods we define additional `HEADER_SEARCH_PATHS` for our `React-Codegen` pod.
This approach will not work if we want to generate code at the library level and check in the artifacts. That's because we don't have control over the Podspec there, and can't inject those additional `HEADER_SEARCH_PATHS`.

This diff adds the `headerPrefix` argument to the codegen entry point. It is `react/renderer/components/${libraryName}` by default, but can become empty if we want to generate code at the library level, and don't want to deal with this nested header structure.

*Note:* `RNCodegen` runs all the generators [in a loop](https://github.com/facebook/react-native/blob/main/packages/react-native-codegen/src/generators/RNCodegen.js#L263-L275), assuming that the all have same function signature So I had to add the `headerPrefix` argument to all the generators, even to the ones that don't really need it.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/39540

This simplifies the use of Codegen when creating dev builds of `rn-tester` in the monorepo. It now runs from source for this internal scenario, and this package is now built using the shared monorepo build setup.

Changes:
- Migrate `packages/react-native-codegen` to the shared `yarn build` setup.
    - Update package to use `"exports"` field and wrap entry point modules with `babel-register` (NOTE: This is only required for each entry point internally used in the monorepo).
- Fixup small Flow syntax quirks that fail under `hermes-parser`.
- Remove `BuildCodegenCLITask` task from Android build.
- Remove Codegen `build.sh` call from iOS build, use `require.resolve` for `combine-js-to-schema-cli.js` entry point.

Externally significant FYIs:
- `react-native/codegen` is converted to use the `"exports"` field — it should export all `.js` files, as before.
- `codegenPath` is now ignored and marked as deprecated on `ReactExtensions.kt`.

NOTE: TypeScript auto-generation is not yet enabled on this package, since it uses CommonJS `module.exports` syntax (unsupported by `flow-api-translator`).

Riccardo CipolleschiandFacebook GitHub Bot b6b09a7e72 Add support for distributed registration of Fabric Components with Dynamic Libraries (#37274)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/37274

With dynamic frameworks, we can't use floating C functions.

The way in which dynamic frameworks work is that they need to be self contained. They are built in isolation so that other frameworks can be linked against them to solve their dependencies.

Currently, when working with 3rd party libraries, we are Codegenerating a RCTThirdPartyComponentProvider which tries to invoke floating C functions that are defined in other modules. React-RCTFabric has no visibility on those modules, therefore it fails building.

The implemented solution exclude the generation of those symbols and leverage a the Objective-C runtime to automatically register libraries when they are loaded.

**This mechanism is applied ONLY when the flag RCT_DYNAMIC_FRAMEWORKS is turned on.** There will be no impact on internal meta apps, nor on any apps that are not using Dynamic Frameworks.

This change requires a small migration in all the Fabric components libraries that wants to support dynamic frameworks. They have to implement a
```
+ (void)load
{
  [super load];
}
```
method in their ComponentView.

Not to slow down the adoption of the new architecture, waiting for a migration in the ecosystem, the next diff introduce a secondary, declarative loading mechanism for Fabric Components, which follows the same approach used by TurboModules.

## Changelog:
[iOS][Changed] - Add support for distributed registration of  Fabric Components with Dynamic Libraries.

Notes that this change is NOT breaking as dynamic frameworks were not working before in the New Architecture. Static Libraries and Static Frameworks continue working as usual.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/36030

Generate enum types in c++ turbo modules.

For enums in the ts schema file such as:
```
export enum NumEnum {
  ONE = 1,
  TWO = 2,
}
```
This would export enums and the relevant Bridging to js and from js code to the spec H files such as:
```
#pragma mark - SampleTurboModuleCxxNumEnum

enum SampleTurboModuleCxxNumEnum { ONE, TWO };

template <>
struct Bridging<SampleTurboModuleCxxNumEnum> {
  static SampleTurboModuleCxxNumEnum fromJs(jsi::Runtime &rt, int32_t value) {

    if (value == 1) {
      return SampleTurboModuleCxxNumEnum::ONE;
    } else if (value == 2) {
      return SampleTurboModuleCxxNumEnum::TWO;
    } else {
      throw jsi::JSError(rt, "No appropriate enum member found for value");
    }
  }

  static jsi::Value toJs(jsi::Runtime &rt, SampleTurboModuleCxxNumEnum value) {
    if (value == SampleTurboModuleCxxNumEnum::ONE) {
      return bridging::toJs(rt, 1);
    } else if (value == SampleTurboModuleCxxNumEnum::TWO) {
      return bridging::toJs(rt, 2);
    } else {
      throw jsi::JSError(rt, "No appropriate enum member found for enum value");
    }
  }
};

```
That code would allow us to use these enums in the cxx files like this:
```
  NativeCxxModuleExampleCxxEnumInt getNumEnum(
      jsi::Runtime &rt,
      NativeCxxModuleExampleCxxEnumInt arg);
```

This modifies the codegen so that the corresponding lambda doesn't capture event variable if it's not used in the event handler, thus getting rid of warnings.

Summary:
i recently made a change to modularize some of our graphics dependencies

i think this codegen will be incorrect now after my diff, so i updated it so we would codegen the correct deps

Jordan BrownandFacebook GitHub Bot 7884f6cfec Implicit instantiation codemod
Summary:
This diff adds explicit type arguments to polymorphic function calls that do not constrain their types. This codemod will reduce the error burden that will come in a future version of flow.

This specific diff was generated by running:
```
flow codemod annotate-implicit-instantiations --write .
flow --json --pretty | jq '.errors | .[] | .message | .[] | .loc |.source' | sort | uniq | sed -e 's/"//g' | xargs hg revert
hg st -n | xargs grep "generated" | sed -e 's/:.*//g' | xargs hg revert
arc f
```

So these are the codemod results that introduced no new errors and no generated files.
