For testing purposes, we define a static global variable here in a function that each individual
test .cpp calls with its initialization lambda. It's convenient here because we can just not
compile some test files to disable/ignore some of the test code.
It is NOT recommended as a way to use pybind11 in practice, however: the initialization order will
be essentially random, which is okay for our test scripts (there are no dependencies between the
individual pybind11 test .cpp files), but most likely not what you want when using pybind11
productively.
Instead, see the "How can I reduce the build time?" question in the "Frequently asked questions"
section of the documentation for good practice on splitting binding code over multiple files.

## Building
Both CMake and Meson tools are capable of generating a variety of build environments for you preferred development environment.
Using cmake or meson you can generate an XCode, Visual Studio, Unix Makefile, Ninja, or other environment that fits your needs.
An example of a common Meson/Ninja environment is described next.
## Building and testing with Meson/Ninja
Thanks to David Seifert (@SoapGentoo), we (the maintainers) now use
[meson](http://mesonbuild.com/) and [ninja](https://ninja-build.org/) to build
for debugging, as well as for continuous integration (see
[`./.travis_scripts/meson_builder.sh`](./.travis_scripts/meson_builder.sh) ). Other systems may work, but minor
things like version strings might break.
First, install both meson (which requires Python3) and ninja.
If you wish to install to a directory other than /usr/local, set an environment variable called DESTDIR with the desired path:
DESTDIR=/path/to/install/dir
Then,
cd jsoncpp/
BUILD_TYPE=debug
#BUILD_TYPE=release
LIB_TYPE=shared
#LIB_TYPE=static
meson --buildtype ${BUILD_TYPE} --default-library ${LIB_TYPE} . build-${LIB_TYPE}
ninja -v -C build-${LIB_TYPE}
cd build-${LIB_TYPE}
meson test --no-rebuild --print-errorlogs
sudo ninja install
## Building and testing with other build systems
See https://github.com/open-source-parsers/jsoncpp/wiki/Building
## Running the tests manually
You need to run tests manually only if you are troubleshooting an issue.
In the instructions below, replace `path/to/jsontest` with the path of the
`jsontest` executable that was compiled on your platform.
cd test
# This will run the Reader/Writer tests
python runjsontests.py path/to/jsontest
# This will run the Reader/Writer tests, using JSONChecker test suite
# (http://www.json.org/JSON_checker/).
# Notes: not all tests pass: JsonCpp is too lenient (for example,
# it allows an integer to start with '0'). The goal is to improve
# strict mode parsing to get all tests to pass.
python runjsontests.py --with-json-checker path/to/jsontest
# This will run the unit tests (mostly Value)
python rununittests.py path/to/test_lib_json
# You can run the tests using valgrind:
python rununittests.py --valgrind path/to/test_lib_json
## Building the documentation
Run the Python script `doxybuild.py` from the top directory:
python doxybuild.py --doxygen=$(which doxygen) --open --with-dot
See `doxybuild.py --help` for options.
## Adding a reader/writer test
To add a test, you need to create two files in test/data:
* a `TESTNAME.json` file, that contains the input document in JSON format.
* a `TESTNAME.expected` file, that contains a flatened representation of the
input document.
The `TESTNAME.expected` file format is as follows:
* Each line represents a JSON element of the element tree represented by the
input document.
* Each line has two parts: the path to access the element separated from the
element value by `=`. Array and object values are always empty (i.e.
represented by either `[]` or `{}`).
* Element path `.` represents the root element, and is used to separate object
members. `[N]` is used to specify the value of an array element at index `N`.
See the examples `test_complex_01.json` and `test_complex_01.expected` to better understand element paths.
## Understanding reader/writer test output
When a test is run, output files are generated beside the input test files. Below is a short description of the content of each file:
* `test_complex_01.json`: input JSON document.
* `test_complex_01.expected`: flattened JSON element tree used to check if
parsing was corrected.
* `test_complex_01.actual`: flattened JSON element tree produced by `jsontest`
from reading `test_complex_01.json`.
* `test_complex_01.rewrite`: JSON document written by `jsontest` using the
`Json::Value` parsed from `test_complex_01.json` and serialized using
`Json::StyledWritter`.
* `test_complex_01.actual-rewrite`: flattened JSON element tree produced by
`jsontest` from reading `test_complex_01.rewrite`.
* `test_complex_01.process-output`: `jsontest` output, typically useful for
understanding parsing errors.
## Versioning rules
Consumers of this library require a strict approach to incrementing versioning of the JsonCpp library. Currently, we follow the below set of rules:
* Any new public symbols require a minor version bump.
* Any alteration or removal of public symbols requires a major version bump, including changing the size of a class. This is necessary for
consumers to do dependency injection properly.
## Preparing code for submission
Generally, JsonCpp's style guide has been pretty relaxed, with the following common themes:
* Variables and function names use lower camel case (E.g. parseValue or collectComments).
* Class use camel case (e.g. OurReader)
* Member variables have a trailing underscore
* Prefer `nullptr` over `NULL`.
* Passing by non-const reference is allowed.
* Single statement if blocks may omit brackets.
* Generally prefer less space over more space.
For an example:
```c++
bool Reader::decodeNumber(Token& token) {
Value decoded;
if (!decodeNumber(token, decoded))
return false;
currentValue().swapPayload(decoded);
currentValue().setOffsetStart(token.start_ - begin_);
currentValue().setOffsetLimit(token.end_ - begin_);
return true;
}
```
Before submitting your code, ensure that you meet the versioning requirements above, follow the style guide of the file you are modifying (or the above rules for new files), and run clang format. Meson exposes clang format with the following command:
```
ninja -v -C build-${LIB_TYPE}/ clang-format
```
