Hi,
I am using optparser to do following...
Command syntax:
myscript -o[exension] other_arguments
where; extension can be 'exe', 'txt', 'pdf', 'ppt' etc.
Now to parse this, I am doing following...
parser.add_option("-oexe', dest=exe_file...)
parser.add_option("-otxt', dest=txt_file...)
parser.add_option("-opdf', dest=pdf_file...)
parser.add_option("-oppt', dest=ppt_file...)
The above way is the most simple way to parser options.
Can you please suggest any other best way / optimized way to parse
these kind of options.
Thank you in advance.
Here's a solution:
import optparse
class Process:
PREFIX = 'dispatch_'
@staticmethod
def undef():
print 'unsupported file type'
@staticmethod
def dispatch_exe():
print 'Hello exe file !'
def dispatchFileType(option, opt, value, parser):
"""Called by the parser, -o option."""
# call the corresponding method in the process method
getattr(Process, Process.PREFIX + value, Process.undef)()
parser = optparse.OptionParser()
parser.add_option("-o", "--output-fileType", type="string",
action="callback", callback=dispatchFileType)
options, args = parser.parse_args()
Cheers,
JM
