 ## Trying out examples
 1. `cd examples/<example_u_want_to_run>`, Run `dart pub get`.
 2. Run `dart run ffigen`.
 
 ## Running Tests
-1. Dynamic library for some tests need to be built before running the examples.
-  1. `cd test/native_test`.
-  2. Run `dart build_test_dylib.dart`.
 
-Run tests from the root of the package with `dart run test`.
-> Note: If llvm is not installed in one of the default locations, tests may fail.
+See [test/README.md](test/README.md)

 ## FAQ
 ### Can ffigen be used for removing underscores or renaming declarations?
 Ffigen supports **regexp based renaming**, the regexp must be a

 Ffigen treats `char*` just as any other pointer,(`Pointer<Int8>`).
 To convert these to/from `String`, you can use [package:ffi](https://pub.dev/packages/ffi). Use `ptr.cast<Utf8>().toDartString()` to convert `char*` to dart `string` and `"str".toNativeUtf8()` to convert `string` to `char*`.
-### How does ffigen handle C99 bool data type?
-
-Although `dart:ffi` doesn't have a NativeType for `bool`, they can be implemented as `Uint8`.
-Ffigen generates dart `bool` for function parameters and return type by default.
-To disable this, and use `int` instead, set `dart-bool: false` in configurations.
 
 ### How are unnamed enums handled?

   - They refer to a struct/union having the same name as itself.
   - They refer to a boolean, enum, inline array, Handle or any unsupported type.
 
+### How are macros handled?
+
+`ffigen` uses `clang`'s own compiler frontend to parse and traverse the `C` header files. `ffigen` expands the macros using `clang`'s macro expansion and then traverses the expanded code. To do this, `ffigen` generates temporary files in a system tmp directory.
+
+A custom temporary directory can be specified by setting the `TEST_TMPDIR` environment variable.

 ### What are these logs generated by ffigen and how to fix them?
 
 Ffigen can sometimes generate a lot of logs, especially when it's parsing a lot of code.

+
+### How can type definitions be shared?
+
+Ffigen can share type definitions using symbol files.
+- A package can generate a symbol file using the `output -> symbol-file` config.
+- And another package can then import this, using `import -> symbol-files` config.
+- Doing so will reuse all the types such as Struct/Unions, and will automatically
+ exclude generating other types (E.g functions, enums, macros).
+
+Checkout `examples/shared_bindings` for details.
+
+For manually reusing definitions from another package, the `library-imports`
+and `type-map` config can be used.

+# Objective C example
+
+This example shows how to use ffigen to generate bindings for an Objective C
+library. It uses the AVFAudio framework to play audio files.
+
+```
+dart play_audio.dart test.mp3
+```
+
+## Config notes
+
+The ffigen config for an Objective C library looks very similar to a C library.
+The most important difference is that you must set `language: objc`. If you want
+to filter which interfaces are included you can use the `objc-interfaces:`
+option. This works similarly to the other filtering options.
+
+It is recommended that you filter out just about everything you're not
+interested in binding (see the ffigen config in [pubspec.yaml](./pubspec.yaml)).
+Virtually all Objective C libraries depend on Apple's internal libraries, which
+are huge. Filtering can reduce the generated bindings from millions of lines to
+tens of thousands. You can use the `exclude-all-by-default` flag, or exclude
+individual sets of declarations like this:
+
+```yaml
+functions:
+  exclude:
+    - '.*'
+# Same for structs/unions/enums etc.
+```
+
+In this example, we're only interested in `AVAudioPlayer`, so we've filtered out
+everything else. But ffigen will automatically pull in anything referenced by
+any of the fields or methods of `AVAudioPlayer`, so we're still able to use
+`NSURL` etc to load our audio file.
+
+## Generating bindings
+
+At the root of this example (`example/objective_c`), run:
+
+```
+dart run ffigen --config config.yaml
+```
+
+This will generate [avf_audio_bindings.dart](./avf_audio_bindings.dart).

+# Swift example
+
+This example shows how to use ffigen to interact with Swift libraries.
+
+Swift APIs can be made compatible with Objective-C, using the `@objc`
+annotation. Then you can use the `swiftc` tool to build a dylib for the library
+using `-emit-library`, and generate an Objective-C wrapper header using
+`-emit-objc-header-path filename.h`:
+
+```shell
+swiftc -c swift_api.swift               \
+    -module-name swift_module           \
+    -emit-objc-header-path swift_api.h  \
+    -emit-library -o libswiftapi.dylib
+```
+
+This should generate libswiftapi.dylib and swift_api.h.
+For more information about Objective-C / Swift interoperability, see the
+[Apple documentation](https://developer.apple.com/documentation/swift/importing-swift-into-objective-c).
+
+Once you have an Objective-C wrapper header, ffigen can parse it like
+any other header:
+
+```shell
+dart run ffigen --config config.yaml
+```
+
+This will generate [swift_api_bindings.dart](./swift_api_bindings.dart),
+using the config in the ffigen section of the pubspec.yaml.
+
+Finally, you can run the example using this command:
+
+```shell
+dart run example.dart
+```
+
+## Config notes
+
+Ffigen only sees the Objective-C wrapper header, swift_api.h. So you
+need to set the language to objc, and set the entry-point to the header:
+
+```yaml
+language: objc
+headers:
+  entry-points:
+    - 'swift_api.h'
+```
+
+Swift classes become Objective-C interfaces, so include them like this:
+
+```yaml
+objc-interfaces:
+  include:
+    - 'SwiftClass'
+```
+
+There is one extra option you need to set when wrapping a Swift library.
+When `swiftc` compiles the library, it gives the Objective-C interface
+a module prefix. Internally, our `SwiftClass` is actually registered
+as `swift_module.SwiftClass`. So you need to tell ffigen about this prefix,
+so it loads the correct class from the dylib:
+
+```yaml
+objc-interfaces:
+  include:
+    - 'SwiftClass'
+  module:
+    'SwiftClass': 'swift_module'
+```
+
+The module prefix is whatever you passed to `swiftc` in the
+`-module-name` flag.

+# ffigen testing
+
+## Running Tests
+
+1.  Some tests require that dynamic libraries be built before running the tests.
+    You can do so with:
+
+    ```shell
+    dart run test/setup.dart
+    ```
+
+2.  Run the tests with:
+
+    ```shell
+    dart test
+    ```
+
+## Development
+
+Some tests verify that the generated Dart FFI bindings match a golden file.
+
+For example, the test
+[`test/native_test/native_test.dart`](https://github.com/dart-lang/ffigen/blob/master/test/native_test/native_test.dart)
+works by:
+
+1.  Loading the dynamic library for
+    [`test/native_test/native_test.c`](https://github.com/dart-lang/ffigen/blob/master/test/native_test/native_test.c)
+    (which was generated by `dart run test/setup.dart`).
+
+2.  Generating binding files for that dynamic library in the
+    `test/debug_generated` directory.
+
+3.  Comparing the golden file (i.e.
+    [`test/native_test/native_test_bindings.dart`](https://github.com/dart-lang/ffigen/blob/master/test/native_test/native_test_bindings.dart))
+    to the generated file and generating a test failure if they do not match.
+
+4.  Using the *golden* bindings to excercise the dynamic library.
+
+If you modify any source for a dynamic library (e.g. any `.c`, `.h` or `.m`
+files), then you should run:
+
+```shell
+   dart run test/setup.dart  # Rebuild the dynamic libraries.
+   dart run test/regen.dart  # Rebuild the golden FFI bindings.
+```
+
+If you modify any code that changes how FFI bindings are generated, then you
+should run:
+
+  ```shell
+  dart run test/regen.dart  # Rebuild the golden FFI bindings.
+  ```
+
+A conservative way to run tests is with:
+
+  ```shell
+  dart run test/setup.dart && dart run test/regen.dart && dart test
+  ```
+
+> Note: you should verify that the changes to the golden bindings are
+> reasonable with `git diff`.
