Plugin for Python

To develop software that extensible and maintainable, we have to separate the concern in our programs. Plugin system is one way to do it. So, I made a Plugin class, for my own programs, that will load python script dynamically.

Here is the code:

class Plugin:

def __init__(self,base,dir):

"""docstring for __"""

self.plugins={}

self.plugin_dir=base+'/'+dir

sys.path.append(self.plugin_dir)

def load(self,fname):

"""docstring for load"""

p=''

if fname.find('.pyc')>0:

p=fname.replace('.pyc','').strip()

#print 'importing:',p

try:

self.plugins[p] = __import__(p)

except:

pass

def load_all(self):

"""docstring for load"""

try:

dir_list=os.listdir(self.plugin_dir)

for fname in dir_list:

self.load(fname)

except Exception, e:

raise e
