* [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

Unfortunately, we lose typing information because the new esbuild method
of generating single files does not generate type information.
The method used here is a bit hack-ish because it relies on parsing the
console output of flatc to figure out what to do.

With a change introduce in 385dda5c3785ed8d6a35868bc169f07e40e889087fd2edc66,
flatc was not able to emit code for Kotlin if a namespace is specified
and the folders do not exist. The fix create folders if neded.
Additional changes are introduced in gradle files to bring more visibility
to the error messages.

* [Kotlin] Move CI js test to Linux action, to increase Mac action speed
* [Kotlin] Generate gradle wrapper in order to be validate
Gradle wrapper from 3.3 to 4.0 are not verifiable because those files
were dynamically generated by Gradle in a non-reproducible way.
So they are now regenerated and will be checked using gitlab action:
gradle/wrapper-validation-action@v1

* combined compile options together. Added Mac CI builds
* remove arm build (not supported). Fixed old-style-casts
* moved to using a ProjectConfig interface library to specify options
* remove the explicit CMAKE_CXX_STANDARD
* removed test/generate_code.{sh|bat}

* refactor: update description in pubspec.yaml to make pub.dev happy
"The package description is too long.
Search engines display only the first part of the description. Try to keep the value of the description field in your package's pubspec.yaml file between 60 and 180 characters."
