* feat: Fixed the issue with nested unions relying on InitFromBuf.
Problem: Issue #7569
Nested Unions were broken with the introduction of parsing buffers with an initial encoding offset.
Fix:
Revert the InitFromBuf method to the previous version and introduction of InitFromPackedBuf that allows
users to read types from packed buffers applying the offset automatically.
Test:
Added in TestNestedUnionTables to test the encoding and decoding ability using a nested table with a
union field.
* fix: Uncommented generate code command
* feat: Added support for fixed sized arrays to python
Problem:
We encountered that using fixed arrays from C++ to python that python would
not read those arrays correctly due to no size information being encoded in the byte
array itself.
Fix:
Encode the sizes within the generated python file during code generation.
Specfically we add GetArrayAsNumpy to the python version of table, which takes as input
the length of the vector. When generating the python message files we include this length
from the VectorType().fixed_length.
* fix: added digit support for camel case to snake case conversion
Problem:
When including a number in the message name we would encounter cases where SnakeCase would
not add the appropirate breaks. e.g. Int32Stamped -> int_32stamped rather than int_32_stamped.
Fix:
To fix this we can add the condition that we check if the current character is not lower and
not a digit, that we check if the previous character was a lower or digit. If it was a lower
or digit then we add the break.
* fix: Array support for structures
Problem:
The python generated code for handling non-struct and struct vectors
and arrays was inconsistent. The calls to populate the obj api was
creating incorrect code.
Solution:
To fix this the VectorOfStruct and VectorOfNonStruct was rewritten
to handle array cases and bring the two methods in line which each
other.
Testing:
PythonTesting.sh now correctly runs and generates the code for
array_test.fbs.
Minor modifications were done on the test to use the new index
accessor for struct arrays and the script correctly sources the
location of the python code.
* chore: clang format changes
* Added code generated by scripts/generate_code. Modified GetArrayOfNonStruct slightly
to allow for function overloading allowing the user to get a single element of an array
or the whole array.
* Added new_line parameter to OffsetPrefix to allow optional new lines to be added.
This allows us to use the GenIndents method that automatically adds new lines instead.
* Reupload of generated code from the scripts/generate_code.py
* Removed new line in GetVectorAsNumpy.
* Updated Array lengths to use Length methods where possible. Added fallthrough for GenTypePointer. Added digit check to CamelToSnake method. Added and modified tests for ToSnakeCase and CamelToSnake.
* Added range check on the getter methods for vector and array types. Renamed == as is for python
Added (for compiler versions that support it):
-Wmissing-declarations
-Wzero-as-null-pointer-constant
Then, fixes to problems identified by the extra warnings
Tested only on GCC 9.4.0
Adjusted the CPP code generator to output nullptr where appropriate,
to satisfy -Wzero-as-null-pointer-constant
Added a lot of 'static' declarations in front of functions,
to satisfy -Wmissing-declarations,
and wrap static function defs in anonymous namespaces.
There are advantages to both anonymous namespaces and static,
it seems that marking a function as static will not publish the name in
the symbol table at all, thus giving the linker less work to do.
* Implement optional scalars for Python
* Use == for integer comparison, remove empty line
* Fix optional type hint

and the one-file code can be tested based on the same test code.
* Sync with google/flatbuffers
* Add --gen-onefile to generate_code.py
* Keep methods with struct name and switch them to default
This PR can help fix the following two issues:
1): A set of simplified API (without struct name) was added in
https://github.com/google/flatbuffers/pull/6336. It causes name
conflict when merging all generated python file into a single one
(the primary usage senario in Google).
2): Flatbuffers 2.0 generates absolute import path, which may cause
name space conflicts. See more details in
https://github.com/google/flatbuffers/issues/5840.
The solution for both is to generate the merged Python code, similar
C++. The merged code will not contain the simplied API, but only the
method with struct name. For issue (1), it will mimic the exactly
usage pattern for Google internal. For issue (2), users can generate
the merged flatbuffer code, without worrying about the imports.
The above idea will be implemented in the following steps:
Step 1 (this PR): revert changes in https://github.com/google/flatbuffers/pull/6336
that set the simplified API as default. Remove statements that the
original API will be deprecated, and reset the original API as default.
Step 2 (the following PR): create a flag to generate the merged code.
The Simplified API will be removed from the merged code, otherwise it
will cause name conflict.
* Update the generated sample code

* [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 commit adds replacement of `::tolower` and `::toupper`.
Added CharToLower and CharToUpper routines reduce the number of cast operators
that required for correct usage of standard C/C++ `::tolower/toupper` routines.
* Fixed refractoring issue in reflection/generate_code.sh. Also, mv deletes the original file, so I don't need to clean it up manually in that case.
* Added --filename-suffix and --filename-ext to flatc
* Fixed typo and added example generation of suffix and extension for C++
* Removed extra ;
* Removed clang-format block from a region that didn't need it. Fixed an auto format of another clang-format block
* Added docs, fixed pointer alignment, removed suffix test file
* 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.
* Fix issues with uint64 enums
- hide the implementation of enums from code generators
- fix uint64 the issue in the cpp-generator
- fix#5108
- new tests
- enums with bit_flags attribute should be unsigned
* Refine objectives of EnumDef's FindByValue and ReverseLookup methods
- move EnumDef::ReverseLookup implementation to idl_parser.cpp
- fix typos
* Make the IsUInt64 method private
This is a port of FlatBuffers to Rust. It provides code generation and a
runtime library derived from the C++ implementation. It utilizes the
Rust type system to provide safe and fast traversal of FlatBuffers data.
There are 188 tests, including many fuzz tests of roundtrips for various
serialization scenarios. Initial benchmarks indicate that the canonical
example payload can be written in ~700ns, and traversed in ~100ns.
Rustaceans may be interested in the Follow, Push, and SafeSliceAccess
traits. These traits lift traversals, reads, writes, and slice accesses
into the type system, providing abstraction with no runtime penalty.
* 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

* 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
