Somo bee1df96dc [Go] Replace references to hardcoded ”Monster" etc with idiomatic go wherever possible (#5716)
* go: replace objAPI-generated Pack func with method

See discussion at https://github.com/google/flatbuffers/issues/5668

* go: replace generated union type UnPack func with method

Similar to discussion https://github.com/google/flatbuffers/issues/5668

But signature:
```
func AnyUnPack(t Any, table flatbuffers.Table) *AnyT
```

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

lu-wang-g 65f8703572 Flatbuffers Python Object API (#5616)
* 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.

Paulo Pinheiro de9aa0cdee Add basic Kotlin support (#5409)
* [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.

Wouter van Oortmerssen b652fcc3a7 Break internal Java/C# APIs

can cause bad decoding results, see:

Kulikov Alexey 4e5152d886 Java: Calculation of vtable and vtable size moved to the __init method. (#5210)
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.

kostya-sh 062dcf7007 Use standard header for generated Go files (#4961)
As recommended by https://golang.org/pkg/cmd/go/internal/generate/:

  To convey to humans and machine tools that code is generated,
  generated source should have a line early in the file that
  matches the following regular expression (in Go syntax):

        ^// Code generated .* DO NOT EDIT\.$

Derek Bailey ba5eb3b5cf Lua (5.3) Language addition (#4804)
* starting Lua port of python implmention. Syncing commit

* Bulk of Lua module port from Python done. Not tested, only static analysis. Need to work on binary strings. Started work on flatc lua code generation

* Fixed all the basic errors to produced a binary output from the builder, don't know if it is generated correctly, but it contains data, so that must be good

* fixed binary set command that was extending the array improperly

* continued improvement

* Moved lua submodules down a directory so their names don't clash with potential other modules. Added compat module to provide Lua versioning logic

* Successful sample port from Python

* working on testing Lua code with formal tests

* continued to work on tests and fixes to code to make tests pass

* Added reading buffer test

* Changed binaryarray implmentation to use a temporary table for storing data, and then serialize it to a string when requested. This double the rate of building flatbuffers compared to the string approach.

* Didn't need encode module as it just added another layer of indirection that isn't need

* profiled reading buffers, optimizations to increase read performance of monster data to ~7 monster / millisecond

* Writing profiler improvments. Get about
~2 monsters/millisecond building rate

* removed Numpy generation from Lua (came from the Python port)

* math.pow is deprecated in Lua 5.3, so changed to ^ notation. Also added .bat script for starting Lua tests

* adding results of generate_code.bat

* simple edits for code review in PR.

* There was a buffer overflow in inserting the keywords into the unorder set for both the Lua and Python code gens. Changed insertion to use iterators.

* fixed spacing issue

* basic documenation/tutorial updates. Updated sample_binary.lua to reflect the tutorial better

* removed windows-specific build step in Lua tests
