Summary:
The codegen helper script, `generate-specs.sh`, is being used to generate code for the FBReactNativeSpec and React-Fabric/rncore pods. The script now supports overriding several defaults by setting the following environment variables:
- SRCS_DIR: Path to JavaScript sources, defaults to $RN_DIR/Libraries/
- LIBRARY_NAME: Defaults to FBReactNativeSpec
- MODULES_OUTPUT_DIR: Defaults to Libraries/$LIBRARY_NAME/$LIBRARY_NAME
- COMPONENTS_LIBRARY_NAME: Defaults to rncore
- COMPONENTS_OUTPUT_DIR: Defaults to ReactCommon/react/renderer/components/$COMPONENTS_LIBRARY_NAME
The CocoaPods codegen integration has been updated to take advantage of these.
**Example CocoaPods usage:**
```
# packages/rn-tester/NativeModuleExample/RNTesterSpecs.podspec
Pod::Spec.new do |s|
s.name = "RNTesterSpec"
# ...
use_react_native_codegen!(s, { :srcs_dir => __dir__, :modules_output_dir => __dir__ })
end
```

# This script collects the JavaScript spec definitions for core

# native modules and components, then uses react-native-codegen
|
|
# to generate native code.
|
|
#
|
|
# Optionally, set these envvars to override defaults:
|
|
# - SRCS_DIR: Path to JavaScript sources
|
|
# - CODEGEN_MODULES_LIBRARY_NAME: Defaults to FBReactNativeSpec
|
|
# - CODEGEN_MODULES_OUTPUT_DIR: Defaults to Libraries/$CODEGEN_MODULES_LIBRARY_NAME/$CODEGEN_MODULES_LIBRARY_NAME
|

# - CODEGEN_COMPONENTS_LIBRARY_NAME: Defaults to rncore
|
|
# - CODEGEN_COMPONENTS_OUTPUT_DIR: Defaults to ReactCommon/react/renderer/components/$CODEGEN_COMPONENTS_LIBRARY_NAME

# Usage:
