如何覆盖 Boost::Python 自动创建的文档字符串数据?
我目前正在为 Python 开发一个基于 C++ 的模块。我发现 Boost::Python 非常适合我想要完成的任务。但是,我现在遇到了 Boost::Python 生成的文档字符串的一些问题。给出以下 Boost::Python 定义:
BOOST_PYTHON_MODULE(gcsmt)
{
class_<gcsmt::Units>("Units", "Sets the units used as input.", no_init)
.def("PrintSupported", &gcsmt::Units::printSupported, "Print out all supported units.")
.def("SetDefault", &gcsmt::Units::setDefaultUnit, "Sets the default unit to be used for inputs/outputs.")
.staticmethod("PrintSupported")
.staticmethod("SetDefault")
.def(self_ns::str(self_ns::self))
;
}
如果我编译,在 Python 中加载模块,并获取有关 gscmt.Units 类的帮助,则输出如下:
>>> help(gcsmt.Units)
Help on class Units in module gcsmt:
class Units(Boost.Python.instance)
| Sets the units used as input.
|
| Method resolution order:
| Units
| Boost.Python.instance
| __builtin__.object
|
| Methods defined here:
|
| __reduce__ = <unnamed Boost.Python function>(...)
|
| __str__(...)
| __str__( (Units)arg1) -> object :
|
| C++ signature :
| _object* __str__(gcsmt::Units {lvalue})
|
| ----------------------------------------------------------------------
| Static methods defined here:
|
| PrintSupported(...)
| PrintSupported() -> None :
| Print out all supported units.
|
| C++ signature :
| void PrintSupported()
|
| SetDefault(...)
| SetDefault( (UnitType)arg1, (str)arg2) -> None :
| Sets the default unit to be used for inputs/outputs.
|
| C++ signature :
| void SetDefault(gcsmt::unitType,std::string)
|
| ----------------------------------------------------------------------
| Data and other attributes defined here:
|
| __init__ = <built-in function __init__>
| Raises an exception
| This class cannot be instantiated from Python
|
| ----------------------------------------------------------------------
| Data descriptors inherited from Boost.Python.instance:
|
| __dict__
|
| __weakref__
|
| ----------------------------------------------------------------------
| Data and other attributes inherited from Boost.Python.instance:
|
| __new__ = <built-in method __new__ of Boost.Python.class object>
| T.__new__(S, ...) -> a new object with type S, a subtype of T
虽然输出的大部分文档对我作为开发人员来说很有价值,对于最终用户来说,其中大部分都是噪音,甚至更糟糕的是,令人困惑。 (例如,我的用户不关心给定方法的 C++ 签名是什么,也不需要查看方法解析顺序或显示的其他隐藏方法)。有什么方法可以覆盖并减少 Boost::Python 设置的文档的级别/详细程度吗?理想情况下,我希望我的文档看起来像这样:
>>> help(gcsmt.Units)
Help on class Units in module gcsmt:
class Units
| Sets the units used as input.
|
| PrintSupported() -> None :
| Print out all supported units.
|
| SetDefault( (UnitType)arg1, (str)arg2) -> None :
| Sets the default unit to be used for inputs/outputs.
I am currently working developing a C++-based module for Python. I have found that Boost::Python is working quite well for what I want to accomplish. However, I am now running into some issues with the docstring that is being generated by Boost::Python. Given the following Boost::Python definitions:
BOOST_PYTHON_MODULE(gcsmt)
{
class_<gcsmt::Units>("Units", "Sets the units used as input.", no_init)
.def("PrintSupported", &gcsmt::Units::printSupported, "Print out all supported units.")
.def("SetDefault", &gcsmt::Units::setDefaultUnit, "Sets the default unit to be used for inputs/outputs.")
.staticmethod("PrintSupported")
.staticmethod("SetDefault")
.def(self_ns::str(self_ns::self))
;
}
If I compile, load my module in Python, and get help on the gscmt.Units class, the output is the following:
>>> help(gcsmt.Units)
Help on class Units in module gcsmt:
class Units(Boost.Python.instance)
| Sets the units used as input.
|
| Method resolution order:

|

| __str__( (Units)arg1) -> object :

| C++ signature :
| _object* __str__(gcsmt::Units {lvalue})
|
| ----------------------------------------------------------------------
| Static methods defined here:
|
| PrintSupported(...)
| PrintSupported() -> None :
| Print out all supported units.
|
| C++ signature :
| void PrintSupported()
|
| SetDefault(...)
| SetDefault( (UnitType)arg1, (str)arg2) -> None :
| Sets the default unit to be used for inputs/outputs.
|
| C++ signature :
| void SetDefault(gcsmt::unitType,std::string)
|
| ----------------------------------------------------------------------
| Data and other attributes defined here:
|
| __init__ = <built-in function __init__>
| Raises an exception
| This class cannot be instantiated from Python
|
| ----------------------------------------------------------------------
| Data descriptors inherited from Boost.Python.instance:
|
| __dict__
|
| __weakref__
|
| ----------------------------------------------------------------------
| Data and other attributes inherited from Boost.Python.instance:
|
| __new__ = <built-in method __new__ of Boost.Python.class object>
| T.__new__(S, ...) -> a new object with type S, a subtype of T
While much of the documentation being output is valuable to me as a developer, most of it would be noise, or even worse, confusing, to an end user. (E.g.- my users don't care what the C++ signature of a given method is, nor do they need to see the Method resolution order, or additional hidden methods that are shown). Is there any way to override, and reduce the level/verbosity of the documentation set up by Boost::Python? Ideally, I'd like my documentation to look something like:
>>> help(gcsmt.Units)
Help on class Units in module gcsmt:
class Units
| Sets the units used as input.
|
| PrintSupported() -> None :
| Print out all supported units.
|
| SetDefault( (UnitType)arg1, (str)arg2) -> None :
| Sets the default unit to be used for inputs/outputs.
