doit 介绍
doit来自于使用构建工具的强大功能来执行任何类型的任务。
下面是一个例子：
def task_imports():
"""find imports from a python module"""
for name, module in PKG_MODULES.by_name.items():
yield {
'name': name,
'file_dep': [module.path],
'actions': [(get_imports, (PKG_MODULES, module.path))],
}
def task_dot():
"""generate a graphviz's dot graph from module imports"""
return {
'targets': ['requests.dot'],
'actions': [module_to_dot],
'getargs': {'imports': ('imports', 'modules')},
'clean': True,
}
def task_draw():
"""generate image from a dot file"""
return {
'file_dep': ['requests.dot'],
'targets': ['requests.png'],
'actions': ['dot -Tpng %(dependencies)s -o %(targets)s'],
'clean': True,
}
$ doit list
dot generate a graphviz's dot graph from module imports
draw generate image from a dot file
imports find imports from a python module
$ doit
. imports:requests.models
. imports:requests.__init__
. imports:requests.help
(...)
. dot
. draw
