* Move `namer.h` and `idl_namer.h` to `include/codegen` so they can be reused from `grpc` dirqectory.
* [gRPC] Update the Python generator to produce typed handlers and Python stubs if requested.
* [gRPC] Document the newly added compiler flags.
This allows enums to be type check with mypy.
They will still behave like ints ->
> IntEnum is the same as Enum,
> but its members are also integers and can be used anywhere
> that an integer can be used.
> If any integer operation is performed with an IntEnum member,
> the resulting value loses its enumeration status.

Only if the --python-typing flag is set.
* [Python] Generate `.pyi` stub files when `--python-typing` is on.
To support this change, the following modifications were made:
- added a new option to disable `numpy` helpers generation;
- added a new flag to control the target Python version:
`--python-version` can be one of the following:
- `0.x.x` – compatible with any Python version;
- `2.x.x` – compatible with Python 2;
- `3.x.x` – compatible with Python 3.
- added codegen utilities for Python;
- added a note that the generated .py file is empty.
* [C++] Update the validator to skip structs in namespaces other than the current one.

The new options are:
- `--grpc-filename-suffix` controls the suffix of the generated files;
- `--grpc-use-system-headers` controls the type of C++ includes generated;
- `--grpc-search-path` controls the directory that contains gRPC runtime;
- `--grpc-additional-header` allows to provide additional dependencies for the generated code.
* [Python] Fix various codegen problems.
This includes:
- escaping keywords happens **after** converting the case:
- currently, `table ClassT` generate `class = Class()` which is invalid Python;
- imports in `one_file` mode use the filename rather than the type name when resolving module names;
- use `filename_suffix` instead of the hardcoded `_generated` one;
- generate empty files if no structs or enums are available. This makes the set of output files more predictable for Bazel.

If a schema contains a message named e.g. FooT and a message named Foo
while the Object API suffix is T, then two classes with colliding names
will be generated. This scenario will produce a C++ compiler error, but
it's confusing.
This patch moves the error to the compiler, allowing the user to more
readily act to correct the issue.

* [Kotlin] Small optimizations and benchmark on deserialization
* [Kotlin] Remove redudant assign() method (use init() instead)
* [Kotlin] Fix benchmark run after change in flatbuffers-java deps
Commit 6e214c3a49 fixes Kotlin build,
but makes the kotlin-benchmark plugin misses the java classes at
runtime, causing NotClassFoundError. The alternative to solve the issue
is to read java's pom.xml to get the latest java version and use it
as dependency. With that we avoid compilation errors on a new version and
keep benchmark plugin happy.
* [Kotlin] Introduction to Kotlin Multiplaform
The first implementation of the Kotlin code generation was made years
ago at the time Kotlin Multiplaform was not stable and Kotlin is mostly
used on JVM-based targets. For this reason the generated code uses java
based runtime.
That design decision comes with many drawbacks, leaving the code
generated more java-like and making it impossible to use more advanced
features of the Kotlin language.
In this change we are adding two parts: A pure, multi-plaform, Kotlin
runtime and a new code generator to accompany it.
* [Kotlin] Remove scalar sign cast from code generation
Now that we have a new runtime the accepts unsigned types, we don't
need to code generate casting back and from signed scalars. This
MR removes this from both code generations and adds the necessary
API to the runtime.
* [Kotlin] Use offset on public API to represent buffer position
Currently, kotlin was following Java's approach of representing objects,
vectors, tables as "Int" (the position of it in the buffer). This change
replaces naked Int with Offset<T>, offering a type-safe API. So,
instead of
fun Table.createTable(b: FlatBufferBuilder, subTable: Int)
We will have
fun Table.createTable(b: FlatBufferBuilder, subTable: Offset<SubTable>)
Making impossible to accidentally switch parameters.
The performance should be similar to use Int as we are using value
class for Offset and ArrayOffset, which most of the time translate to
Int in the bytecode.
* [Kotlin] Add builder for tables
Add builder constructor to make create of table more ergonomic.
For example the movie sample for the test set could be written as:
Movie.createMovie(fbb,
mainCharacterType = Character_.MuLan,
mainCharacter = att) {
charactersType = charsType
this.characters = characters
}
instead of:
Movie.startMovie(fbb)
Movie.addMainCharacterType(fbb, Character_.MuLan)
Movie.addMainCharacter(fbb, att as Offset<Any>)
Movie.addCharactersType(fbb, charsType)
Movie.addCharacters(fbb, charsVec)
Movie.endMovie(fbb)
* [Kotlin] Move enum types to value class
Moving to flatbuffer enums to value class adds type safety for parameters
with minimum to no performance impact.
* [Kotlin] Simplify Union parameters to avoid naked casting
Just a small change on the APIs that receive union as parameters,
creating a typealias UnionOffset to avoid using Offset<Any>. To "convert"
an table offset to an union, one just call Offset.toUnion().
* [Kotlin] Apply clang-format on kotlin code generators
* [Kotlin] Update kotlin generator to follow official naming conventions
Updating directory, package and enum naming to follow Kotlin official
convention.
https://kotlinlang.org/docs/coding-conventions.html#naming-rules
* [Kotlin] Add fixes to improve performance
1 - Add benchmark comparing serialization between Java & Kotlin
2 - ReadWriteBuffer does not auto-grow (thus avoid check size in every op)
3 - Add specialized add functions on FlatBufferBuilder to avoid boxing
offsets.
4 - Remove a few Kotlin syntax sugar that generated performance penalties.
* [Kotlin] Remove builder from Kotlin KMP and add some optimizations
to avoid boxing of Offset classes
