Re: Access to static members from inside a method decorator?

[urielka]

no need for all that,i wrote a basic Ajax framework for cherrypy that
features a Ajax.Net feature,exposing functions to JavaScript via
attributes(or in python via decorators),here is a decorator that run
one time(i.e. before running the actual code) and get the name of the
class
[code]
def AddFunction(func):
stack=inspect.stack()
ClsName=stack[1][3]#get the class name from the stack
#now you both have the ClassName and the func object,so you can
populate your list
return func#return the decorated function
[/code]
it use the module inspect,to inspect the stack.

Re: Looking for the Perfect Editor

[urielka]

use Eclipse!!!
it is not a editor but it is the best free IDE out there.
for python use Pydev(pydev.sf.net) plugin:it got
EVERYTHING:completteion,debuging(with thread support)you can`t work
without a debugger for serious projects.
for Web Develop use Aptana(aptana.com) another plugin for eclipse,in
eairly stages but it is very amazing support most of open source
javascript library with auto-complete and outline of code.
Scribes look very nice for a editor i will try it for lightweight
editing.

accepts decorator

[urielka]

i want to make a decorator that make a function accept only types,if
the types are wrong but the number of types is equal to arguments try
to convert them to the type.

for example:

@Accept(int,int)
def Sum(a,b):
return a+b

print Sum("2",2.0)

this should print 4,coz the decorator sees that there is the same
amount of arguments in Accept and Sum,then it will try to cast them to
the types(a to int and also b to int),then he will send them to the
normal function so Sum will get a=2,b=2 instead of a="2"(string)
b=2.0(float).
i made this but it doesn`t work:
def Accept(*types):
def check_accepts(f):
assert len(types) == f.func_code.co_argcount-1,"Not
Enougth/Too much Types"
Types=types
def new_f(*args, **kwds):
newArgs=[]
for (a, t) in zip(kwds.values(), Types):
try:
newArgs.append(t(a))
except:
raise Exception("Convertion of %s to type %s
failed" %(a,t))
nargs=tuple(newArgs)
return f(*nargs, **kwds)
new_f.func_name = f.func_name
return new_f
return check_accepts

it doesn`t work when i decorate a instance method.
i get in *args the instance and in **kwds the arguments,but if it is
just a function not a instance method i get in *args the arguments and
in **kwds a empty dict.

can someone also explain me what is  * and ** ,and how they are called.

Thanks,
-Uriel Katz

Re: accepts decorator

[urielka]

i think i got what the * and ** mean.
*args mean arguments that are assigned by position(that is why *arg is
a tuple)
**kwds mean arguments that are assigned using equals a=2,b=3 (that is
why **kwds i a dict)
but why self is in *args and other thing goes to **kwds? even if not
assigned using equals

Re: accepts decorator

[urielka]

hehe i saw that,that is what made my understand it.
the decorator now works.
let say i have a function decorated with two decorators:

@Accept(int,int)
@OtherDecorator
def myfunc(a,b):
pass

how can i make the two decorators into one(note:one get parameters and
the other doesn`t)

Re: object references/memory access

[urielka]

if both the search server and the web server/script are in the same
computer you could use POSH(http://poshmodule.sourceforge.net/) for
memory sharing or if you are in UNIX you can use mmap.
this is way faster than using sockets and doesn`t require the
serialization/deserialization step.

Interop between C# and Python

[urielka]

i need a easy way to write a Python Service(be it SOAP or JSONRPC or
whatever) but i need to easily access it from C#,i created a web
service in ZSI(which is really easy) like this:

from ZSI import dispatch

def hello():
return "hello"

dispatch.AsServer(port=8080)

simple and easy but how i access it from C#,where is the wsdl for the
service?

is there any easier way to get this kind of interop?(not using a
custom protocol over sockets)

thx,

Re: Interop between C# and Python

[urielka]

thx i will try this.

i am also trying XML-RPC,i wrote a basic generator(in python) that
genrate a Interface from the XML-RPC service module,but maybe with
soaplib i don`t need this if i use wsdl as Visual Studio can generate
the code from the wsdl

unittest dependencies

[urielka]

i am using unittest to test a project,and one thing i really want is a
way to say that test a depends on test b,so it need to run before it
and be successful in order to run this test.

i just wanted to know if anyone have done it before(i searched for it
but didn`t find something useful),i think it can be done easily using
a decorator that will run the test which is depend on and mark it as
successful,the only problem will be detecting circular test
dependencies,but that can be fixed by keeping all the functions that
the decorator have seen.

what do you guys think? did someone did it before?
