hi,

Hi, Vitaly!

I'm trying to accomplish to work couple of CLI commands without luck.

http://twistedmatrix.com/projects/core/documentation/howto/options.htmland test/test_usage.py were not really helpful.

Why weren't these helpful? To me, they seem to clearly explain everything you're trying to do.

First of all - I'm sorry, I've succeed to accomplish first two commands with previous doc link partially: I can't read value per key ... Trying to follow the following snip, how can I read for example value of key -m? CLI: python test.py import -m 'abc321' from twisted.python import usage import sys class ImportOptions(usage.Options): optParameters = [ ['module', 'm', 1, None], ['vendor', 'v', None, None], ['release', 'r', None] ] class CheckoutOptions(usage.Options): optParameters = [['module', 'm', None, None], ['tag', 'r', None, None]] class Options(usage.Options): subCommands = [['import', None, ImportOptions, "Do an Import"], ['checkout', None, CheckoutOptions, "Do a Checkout"]] optParameters = [ ['compression', 'z', 0, 'Use compression'], ['repository', 'r', None, 'Specify an alternate repository'] ] def doImport(): print "TODO: how can I now read the value of key, let's say of -m key?" def doCheckout(): print "TODO: same as doImport()" config = Options() try: config.parseOptions() except usage.UsageError, errortext: print '%s: %s' % (sys.argv[0], errortext) print '%s: Try --help for usage details.' % (sys.argv[0]) sys.exit(1) if config.subCommand == 'import': doImport(config.subOptions) elif config.subCommand == 'checkout': doCheckout(config.subOptions)

...

Commands: 1.python test.py cmd1 -s 'dfsgdfg' -e 'sdfgdfg' 2.python test.py cmd2 -t 123 3.python test.py cmd3 cmd4 -t '2345ge' -y 'rebtr' cmd5 -p 'wgerg'

These commands are way too abstract. Especially that last one ("cmd3 cmd4") could be interpreted in a few different ways. Can you provide a more specific example of what you're actually trying to do, and what the Options API, documentation, and tests don't explain?

bingo! thank you guys a lot! it was all about 'repr(self['module'])'. Glyph, sorry man, did mean to hurt and shit on twisted: personally and professionally I think its a VERY professional framework, and I'm using it about a year. Good job guys, keep doing. Quoting exarkun@twistedmatrix.com:

from twisted.python import usage import sys

class ImportOptions(usage.Options): optParameters = [ ['module', 'm', 1, None], ['vendor', 'v', None, None], ['release', 'r', None] ]

I think the idiomatic approach would be to add another method to this class to replace the "doImport" function below:

def execute(self): print "My -m option was", repr(self['module'])

...

class CheckoutOptions(usage.Options): optParameters = [['module', 'm', None, None], ['tag', 'r', None, None]]

And again here, replacing "doCheckout":

def execute(self): print "*My* -m option was", repr(self['module'])

...

class Options(usage.Options): subCommands = [['import', None, ImportOptions, "Do an Import"], ['checkout', None, CheckoutOptions, "Do a Checkout"]]

optParameters = [ ['compression', 'z', 0, 'Use compression'], ['repository', 'r', None, 'Specify an alternate repository'] ]

def doImport(): print "TODO: how can I now read the value of key, let's say of -m key?"

def doCheckout(): print "TODO: same as doImport()"

config = Options() try: config.parseOptions() except usage.UsageError, errortext: print '%s: %s' % (sys.argv[0], errortext) print '%s: Try --help for usage details.' % (sys.argv[0]) sys.exit(1)

if config.subCommand == 'import': doImport(config.subOptions) elif config.subCommand == 'checkout': doCheckout(config.subOptions)

Then replace this thing with this:

config.subOptions.execute()

But the answer to your original question seems to just be "options[optionName]".
