* 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)
The rationale for this option is that JSON clients typically want empty arrays (i.e [] in the JSON) instead of missing properties, but not empty strings when the value isn't set.
--force-empty is kept as-is, i.e. it will force both empty strings and vectors.
Closes#5652
* 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.
* c++: Add command line option to add extra includes to gen files
Fixes#5351
We have an ability to pass custom types for strings, allocators, etc
but have no way to tell the generator to include the classes in gen code
* c++: remove std::strtok for std::string methods. passes msvc compile
* generate_code.sh: add --cpp-includes to the test gen script
* tests:generate.bat: update code gen scripts w/ --cpp-includes
* cpp: use command line parsing for extra includes
s/--cpp-includes/--cpp-include/g
Simplify command line parsing of includes by using a std::vector.
* cpp: idl.h: move std::vector for cpp_includes as the last member
msvc does not understand initalization list on our CI server
* cpp:msvc: CI fails on for-range loops
* cpp:codegen: fix error reporting on flatcc
* as per code review: remove unwated --cpp-include in the
tests/generate_code.{sh,bat}
implement better custom string type constructor alternative
for Unpack() and fix bug with vector of custom string types
in Pack().

* 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.
* Add --force-defaults option to flatc
To emit default values for fields which are not present or which are set
to the default value.
* flatc option --force-defaults should have a default value (false) and take action on the builder_ within the Parser constructor
* Add help text from flatc --force-defaults to Compiler.md doc
* Clarified docs for flatc --force-defaults, and imply that this behaviour is not normally needed.
* Updated docs and flatc help text for --force-defaults option
* Add suppport for ES6 style exports
Adds support for ECMAScript 6 module exports during Javascript
generation. This is useful as many development projects are
switching to this new standard and away from custom module
solutions. By integrating support into flatbuffers, users
do not need to perform additional post-processing of generated
files in order to use flatbuffers output directly in their
codebases.
Reference to ECMAScript 6 modules:
https://www.ecma-international.org/ecma-262/6.0/#sec-exports
Changes:
* Added `--es6-js-export` option to cli parser tool
* Added conditional code to generate a ES6 style export
line, replacing the normal NodeJS/RequireJS line.
* Fixed missing export statements
Added exports for definition and struct names that were not inside namespaces
* Updated Compiler.md with new generator option
Added entry to Compiler.md in docs for the `--es6-js-export` flag, including a brief description of the effects and usefulness.
Adding an API reference for the supported languages.
General docs cleanup, including a new `tutorial` section that
supports all of the supported languages.
Added samples for each supported language to mirror the new
tutorial page.
Cleaned up all the links by making them `@ref` style links,
instead of referencing the names of the generated `.html` files.
Removed all generated files that were unnecessarily committed.
Also fixed the C# tests (two were failing due to a missing file).
Bug: b/25801305
Tested: Tested all samples on Ubuntu, Mac, and Android. Docs were
generated using doxygen and viewed on Chrome.

It used to be such that later schemas could depend on earlier
schemas. This was a convenience from days before include files
were implemented. Nowadays they cause subtle bugs rather than being
useful, so this functionality has been removed.
You now need to explicitly include files you depend upon.
Change-Id: Id8292c3c621fc38fbd796da2d2cbdd63efc230d1
Tested: on Linux.
Also, removed the flag from the Android makefile.
Tested:
Verified flatc builds successfully on Linux and regenerated the docs.

Normal behavior is to not output fields that happen to have
the default value, since those will be reproduced anyway
when turned into a FlatBuffer binary. This however can be problematic
when using JSON to interop with other system since they might not
know this default value. This flatc option (and also flag
to GenerateText) will force those fields to be output anyway.
Tested: on Linux.
By default, disallow reading binaries that do not correspond to
the schema file_identifier. Override with --raw-binary
Change-Id: I24822c0e4c80dab4e5a238ae2b6e601a09025c27
Tested: on Linux.
This commit contains the first step in providing mutable FlatBuffers,
non-const accessors and mutation functions for existing fields generated
from --gen-mutable.
Change-Id: Iebee3975f05c1001f8e22824725edeaa6d85fbee
Tested: on Linux.
Bug: 15777024
Unless in --strict-json mode.
Also added strict_json option to the parser, which in
addition controls if field names without quotes are allowed.
Change-Id: Id56fe5c780bdb9170958050ffa8fa23cf2babe95
Tested: on Linux.
Also removed it appending _wire to filenames, renamed the json golden
file to .golden to not clash with generated files.
Bug: 15781201
Change-Id: I8322861e50d1e5b6a5ab5e4b5e5d8ae13c356eb2
Tested: on Windows and Linux
This will add quotes around field names, as required by the official
standard. By default it will leave quotes out, as it is more readable,
more compact, and is accepted by almost all JSON parsers.
The -S switch to flatc turns on strict mode.
As per rfc 7159.
Change-Id: Ibabe9c8162c47339d00ec581d18721a2ba40c6d0
