* 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)
* 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.

- update C++ monster_test::Color to unsigned type
- update Go Color:ubyte in the go_test.go
- add workaround for unsigned enum in java test
- sync generate.bat and generate.sh
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.
* Add `NaN` and `Inf` defaults to the C++ generated code.
* Refactoring: add FloatConstantGenerator
* Refactoring-2:
- remove isnan checking for all float/double values
- add most probable implementation of virtual methods of FloatConstantGenerator
* Add conditional (FLATBUFFERS_NAN_DEFAULTS) isnan checking
* Enable flatbuffer to initialize Parser from bfbs (#4283)
Now its possible to generate json data from bfbs data type and flatbuffers data
and visa versa.
* add deserialize functionality in parser from bfbs
* add small usage sample
* Fix build break
* Merge branch 'pr/1' into fix-issue4283
* Fix buildbreak
* Build monster_test.bfbs with --bfbs-builtins
Attribute flexbuffer has be included in bfbs. Only with this attribute test
will run. By initialization a parser by a bfbs the attribute has to be known
for this filed. monsterdata_test.golden has a flexbuffer field so parse would
fail.
* Fix generate_code.sh
* Revert automatic indent changes by IDE
* Auto detect size prefixed binary schema files
* Use identifier (bfbs) to detect schema files
* call reflection code generation from tests
This simplifies instructions to contributors so they don't forget to update
reflection code.
* add error handling to generate_code scripts
Let them propagate their errors instead of swallowing them so they show
up when called in CI.
* apply editorconfig to shell scripts
* use ordered map in dart codegen
Using an unordered map in the codegen can lead to spurious diffs in the
generated dart code.
* add CI check for generate_code being run
* update reflection_generated.h
* disable diff-check for monster_test.bfbs
Work around #5008.
* Add operator== for c++ genated code
New "--gen-compare" option for flatc to generate compare operators. The operators are defined based on object based api types.
Inspired by issue #263.
* Improve compare operator for c++.
Thanks for the code review.
- Improve robustness against future schema extensions
- Code style
- Fix --rust generation in generate_code.sh
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
* 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.

Changing to keep include prefixes had two side effects: the main
file being parsed wasn't filtered out anymore, and include directory
paths would be added to the path in the include statement.
Also moved the include_test*.fbs files to sub directories so we
can actually test the handling of -I etc.
tested: on Linux.

Currently, we do not register this library to packagist as still experimental and versioning problem.
If you intended to use flatbuffers with composer. add repostiories section to composer.json like below.
"repositories": [{
"type": "vcs",
"url": "https://github.com/google/flatbuffers"
}],
and just put google/flatbuffers.
"require": {
"google/flatbuffers": "*"
}
* PHP's integer is platform dependant. we strongly recommend use 64bit machine
and don't use uint, ulong types as prevent overflow issue.
ref: http://php.net/manual/en/language.types.integer.php
* php don't support float type. floating point numbers are always parsed as double precision internally.
ref: http://php.net/manual/en/language.types.float.php
* ByteBuffer is little bit slow implemnentation due to many chr/ord function calls. Especially encoding objects.
This is expected performance as PHP5 has parsing arguments overhead. probably we'll add C-extension.
Basically, PHP implementation respects Java and C# implementation.
Note: ByteBuffer and FlatBuffersBuilder class are not intended to use other purposes.
we may change internal API foreseeable future.
PSR-2, PSR-4 standards.
Implemented simple assertion class (respect JavaScript testcase implementation) as we prefer small code base.
this also keeps CI iteration speed.
we'll choose phpunit or something when the test cases grown.
