* Those methods **MUST** be in your type's namespace (which can be the global namespace), or the library will not be able to locate them (in this example, they are in namespace `ns`, where `person` is defined).
* Those methods **MUST** be available (e.g., properly headers must be included) everywhere you use these conversions. Look at [issue 1108](https://github.com/nlohmann/json/issues/1108) for errors that may occur otherwise.

* When using `get<your_type>()`, `your_type` **MUST** be [DefaultConstructible](https://en.cppreference.com/w/cpp/named_req/DefaultConstructible). (There is a way to bypass this requirement described later.)
* In function `from_json`, use function [`at()`](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_a93403e803947b86f4da2d1fb3345cf2c.html#a93403e803947b86f4da2d1fb3345cf2c) to access the object values rather than `operator[]`. In case a key does not exist, `at` throws an exception that you can handle, whereas `operator[]` exhibits undefined behavior.
* You do not need to add serializers or deserializers for STL types like `std::vector`: the library already implements these.

Check whether an element exists in a JSON object with key equivalent to

that is not an object.

Cpplint is a command-line tool to check C/C++ files for style issues following `Google's C++ style guide <http://google.github.io/styleguide/cppguide.html>`_.
Cpplint is developed and maintained by Google Inc. at `google/styleguide <https://github.com/google/styleguide>`_, also see see the `wikipedia entry <http://en.wikipedia.org/wiki/Cpplint>`_
While Google maintains cpplint, Google is not (very) responsive to issues and pull requests, this fork aims to be (somewhat) more open to add fixes to cpplint to enable fixes, when those fixes make cpplint usable in wider contexts.
Installation
============
To install cpplint from PyPI, run:
.. code-block:: bash
$ pip install cpplint
Then run it with:
.. code-block:: bash
$ cpplint [OPTIONS] files
For full usage instructions, run:
.. code-block:: bash
$ cpplint --help
Changes
-------
The modifications in this fork are minor fixes and cosmetic changes:
* more default extensions
* python 3 compatibility
* customizable file extensions with the --extensions argument
* continuous integration on travis
* support for recursive file discovery via the --recursive argument
* support for excluding files via --exclude
* JUnit XML output format
* Overriding repository root auto-detection via --repository
* Support ``#pragma once`` as an alternative to header include guards
Acknowledgements
----------------
Thanks to Google Inc. for open-sourcing their in-house tool.
