This commit also adds `doc()` to `object_api` as a shortcut for the
`attr("__doc__")` accessor.
The module macro changes from:
```c++
PYBIND11_PLUGIN(example) {
pybind11::module m("example", "pybind11 example plugin");
m.def("add", [](int a, int b) { return a + b; });
return m.ptr();
}
```
to:
```c++
PYBIND11_MODULE(example, m) {
m.doc() = "pybind11 example plugin";
m.def("add", [](int a, int b) { return a + b; });
}
```
Using the old macro results in a deprecation warning. The warning
actually points to the `pybind11_init` function (since attributes
don't bind to macros), but the message should be quite clear:
"PYBIND11_PLUGIN is deprecated, use PYBIND11_MODULE".

/*
|
|
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.
