* [Python] Codegen SizeOf classmethod for structs
This codegens a `SizeOf()` classmethod for all structs since we can't
determine the size of a FlatBuffer generated struct from Python otherwise.
* [JS/TS] Codegen sizeOf static method for structs
This codegens a `sizeOf()` static method for all structs since we can't
determine the size of a FlatBuffer generated struct from JavaScript or
TypeScript otherwise.
This optionally generates a static `getFullyQualifiedName()` function to get
the fully-qualified name of a type in JavaScript and TypeScript in a similar
fashion to the C++ codegen.
Dart schema compiler generated a static getter for enum values, which
always created a new map instance for its callers. See #5819.
Now it generates const map for better performance
and readability.

For example:
include/flatbuffers/reflection.h:365:8: error: definition of implicit copy
constructor for 'pointer_inside_vector<flatbuffers::Table, unsigned char>'
is deprecated because it has a user-declared copy assignment operator
[-Werror,-Wdeprecated-copy]
void operator=(const pointer_inside_vector &piv);
^
It's unclear why the old code wanted to declare a public `operator=`
without defining it; that just seems like a misunderstanding of the C++03 idiom
for deleting a member function. And anyway, we don't *want* to delete the
assignment operator; these are polymorphic types that do not follow value
semantics and nobody should ever be trying to copy them. So the simplest fix
is just to go back to the Rule of Zero: remove the declaration of `operator=`
and let the compiler do what it wanted to do originally anyway.
"The best code is no code."
Also, update the generated .h files.
Fixes#5649.

Previously UnPack would allocate data with new and assign it to a
raw pointer. This behavior makes it possible for the pointer to be
leaked in case of OOM. This commit defaults to use the user specified
pointer (which needs to implement a move constructor, a .get() and a
.release() operators), thus preventing these leaks.

* Bugfix for Rust generation of union fields named with language keywords
Looking at ParseField, it appears that in the case of unions, an extra field with a `UnionTypeFieldSuffix` is added to the type definition, however, if the name of this field is a keyword in the target language, it isn't escaped.
For example, if generating code for rust for a union field named `type`, flatc will generate a (non-keyword escaped) field named `type_type` for this hidden union field, and one (keyword escaped) called `type_` for the actual union contents.
When the union accessors are generated, they refer to this `type_type` field, but they will escape it mistakenly, generating code like this:
```
#[inline]
#[allow(non_snake_case)]
pub fn type__as_int(&self) -> Option<Int<'a>> {
if self.type__type() == Type::Int {
self.type_().map(|u| Int::init_from_table(u))
} else {
None
}
}
```
Which will fail to build because the field is called `self.type_type()`, not `self.type__type()`.
* [Rust] Add crate-relative use statements for FBS includes.
At present if a flatbuffer description includes a reference to a type in
another file, the generated Rust code needs to be hand-modified to add
the appropriate `use` statements.
This assumes that the dependencies are built into the same crate, which
I think is a reasonable assumption?
* Revert "[Rust] Add crate-relative use statements for FBS includes."
This reverts commit d554d79fec.
* Add updated generated test files.
* Fixing Rust test harness to handle new includes.
Test binaries need to add references to generated code that's
transitively included.
This also has the knock-on in that this code (which is referenced by
include directives directly in the flatbuffer schema files) also needs
to be generated, hence the changes to generate_code.sh.
* Test harnesses expect test data to be checked in.
Put include_test2 files into the same directory as the include_test2
schema definition.
Update all code generation scripts (forgot the batch file from last
time).
Path updates in Rust test.
* Include updated generated code

```
Becomes,
```
func (rcv Any) UnPack(table flatbuffers.Table) *AnyT

* Address comments raised in PR
* Update documentation comments per feedback
* Fix typo
* [rust] Make enum variant names public.
* Update generated test files
* Add test for public enum names
* Add Builder and Table typedefs
This gives us a way to use templates to go from a builder to a table
and back again without having to pass both types in.
* Fix tests/cpp17/generated_cpp17/monster_test_generated.h
* Add flatc '--cpp_std' switch and sandbox for C++17 code generator
- Added 'flac --cpp_std legacy' for compatibility with old compilers (VS2010);
- Added experimental switch 'flac --cpp_std c++17' for future development;
- Added C++17 sandbox test_cpp17.cpp;
- C++ code generator generates enums with explicit underlying type to avoid problems with the forward and backward schema compatibility;
- Adjusted CMakeLists.txt, CI and generate code scripts to support of introduced '--cpp_std';
* Fix --cpp_std values: c++0x, c++11, c++17
* Add 'cpp::CppStandard' enum
* Add testing engine into test_cpp17
* Rebase to upstream/master
* Set default '--cpp-std C++0x'
* Fix code generation (--cpp_std C++11) in CMakeLists.txt
- Fix dependency declaration of grpctest target
* Revert --cpp-std for the tests from explicit C++11 to flatc default value (C++0x)
* Make Rust constants public
Otherwise they cannot be accessed by code that consumes the generated
bindings.
* Re-generate test code
* Add a test for enum constants
* Flatbuffers Python Object API
Implement the logic to generate the Python object API that can
unpack the data from a buf class into an object class, and pack
the data of an object class to a buf class.
* Fix the build issues
Remove unused parameters and replace auto in the for-loop statement
with std::string to make it compatible with VS2010.
* Fix the build issues.
* Add support for Array type
Added logic to handle Array type in Python Object API. Updated the
generated code accordingly.
* Fix the old style casting from int to char
* Fixed another conversion from int to char
* Fixed the import for typing
Importing typing may cause errors when a machine do not have the
moduel typing installed. This PR fixes the issue by guarding
"import typing" with the "try/except" statement.
* Fix issue of iterating the vector of import list
* Update the generated examples using generate_code.sh
* Fix the import order for typing
The import list was stored in unordered_set, so that each generated
codes may have different import order. Therefore, it failed in the
consistency test where two generated copies need to have exactly the
same apperance.
* Optimize unpack using numpy
Use numpy to unpack vector whenever it is possible to improve unpack
performance.
Also, added codegen command for Python specificly in generate_code.sh,
because --no-includes cannot be turn on for Python.
* Fix the import order
* Update generate_code.bat for windows accordingly
* Replace error message with pass
Avoid printing error message for every Python2 users about typing.
Replace it with pass.
* [Kotlin] Add kotlin generate code for tests and add
kotlin test to TestAll.sh
* [Kotlin] Add Kotlin generator
This change adds support for generating Kotlin classes.
The approach of this generator is to keep it as close
as possible to the java generator for now, in order
to keep the change simple.
It uses the already implemented java runtime,
so we don't support cross-platform nor js Kotlin yet.
Kotlin tests are just a copy of the java tests.
* Add optional ident support for CodeWriter
Identation is important for some languages and
different projects have different ways of ident
code, e.g. tabs vs spaces, so we are adding optional
support on CodeWriter for identation.
* [Kotlin] Add Documentation for Kotlin
* [Kotlin] Modify generated code to use experimental Unsigned types.
* Add FLATBUFFERS_COMPATIBILITY string
- Add a new __reset method NET/JAVA which hides internal state
* Resolve PR notes
* Use operator new() to __init of Struct and Table
* Restrict visibility of C# Table/Struct to internal level
This is done on purpose, to avoid API version mismatches that
can cause bad decoding results, see:
https://github.com/google/flatbuffers/issues/5368

* [Go] Make enums into real types, add String()
This changes the generated code for enums: instead of type aliases,
they're now distinct types, allowing for better type-checking. Some
client code may have to be changed to add casts.
Enum types now have a String() method, so they implement fmt.Stringer.
An EnumValues map is now generated, in addition to the existing
EnumNames map, to easily map strings to values.
Generated enum files are now gofmt-clean.
Fixes#5207

* Don't use inner attributes for `allow`
Messes with being able to easily include elsewhere
* Regenerate tests
* No-op to retrigger CI
* Add the rest of the `allow` attributes
vtable and vtable size depends only on `Table#bb_pos` but calculated in
`Table#_offset` method on each field lookup.
Doing this with every call of `Table#__offset` is redundant.
These values can be read once with change of `Table#bb_pos` and reused
for any field lookup.
