我正在做以下小項目：

https://github.com/AndreaCrotti/project-organizer

簡而言之,它旨在更容易地管理許多不同的項目.

其中一個有用的方法是自動檢測我正在處理的項目類型,以正確設置一些命令.

目前我正在使用classmethod“匹配”函數和一個迭代各種“匹配”的檢測函數.

我相信可能有更好的設計,但找不到它.

有任何想法嗎？

class ProjectType(object):

build_cmd = ""

@classmethod

def match(cls, _):

return True

class PythonProject(ProjectType):

build_cmd = "python setup.py develop --user"

@classmethod

def match(cls, base):

return path.isfile(path.join(base, 'setup.py'))

class AutoconfProject(ProjectType):

#TODO: there should be also a way to configure it

build_cmd = "./configure && make -j3"

@classmethod

def match(cls, base):

markers = ('configure.in', 'configure.ac', 'makefile.am')

return any(path.isfile(path.join(base, x)) for x in markers)

class MakefileOnly(ProjectType):

build_cmd = "make"

@classmethod

def match(cls, base):

# if we can count on the order the first check is not useful

return (not AutoconfProject.match(base)) and \

(path.isfile(path.join(base, 'Makefile')))

def detect_project_type(path):

prj_types = (PythonProject, AutoconfProject, MakefileOnly, ProjectType)

for p in prj_types:

if p.match(path):

return p()
