Python setuptools 自定义配置

Question

我正在打包一个 Python 模块，我希望用户能够使用一些自定义选项构建该模块。具体来说，如果您为它提供它可以使用的某些可执行文件，该包将发挥一些额外的作用。

理想情况下，用户将运行 setup.py install 或 setup.py install --magic-doer=/path/to/executable。如果他们使用第二个选项，我会在代码中的某处设置一个变量，然后从那里开始。

使用 Python 的 setuptools 可以吗？如果可以，我该怎么做？

看来你可以......阅读this .

文章摘录:

Commands are simple class that derives from setuptools.Command, and define some minimum elements, which are:

description: describe the command
user_options: a list of options
initialize_options(): called at startup
finalize_options(): called at the end
run(): called to run the command

The setuptools doc is still empty about subclassing Command, but a minimal class will look like this:

 class MyCommand(Command):
     """setuptools Command"""
     description = "run my command"
     user_options = tuple()
     def initialize_options(self):
         """init options"""
         pass

     def finalize_options(self):
         """finalize options"""
         pass

     def run(self):
         """runner"""
         XXX DO THE JOB HERE

The class can then be hook as a command, using an entry point in its setup.py file:

 setup(
     # ...
     entry_points = {
     "distutils.commands": [
     "my_command = mypackage.some_module:MyCommand"]}
