It's a best way to break your app =)
Your code without shortgen looks like:
def fetch(arg1, arg2, callback):
pass
@tornado.gen.engine
def get(self):
value = yield tornado.gen.Task(fetch,
arg1='arg1', arg1='arg2'
)
self.write(value)But with shortgen evil magic:
@fastgen
def fetch(arg1, arg2, callback):
pass
@tornado.gen.engine
@shortgen
def get(self):
value << fetch(
arg1='arg1', arg1='arg2'
)
self.write(value)Call exist code like assyncmongo, patch and call with '_e':
from evilshortgen import shortgen, shortpatch
from asyncmongo.cursor import Cursor
shortpatch(Cursor)
@tornado.gen.engine
@shortgen
def get(self):
result, status << self.db.users.find_one_e({
'_id': ObjectId(self.user_id),
},
)Call new code with decorator:
from evilshortgen import shortgen, fastgen
@fastgen
def fetch(arg1, arg2, callback):
pass
@tornado.gen.engine
@shortgen
def get(self):
value << fetch(
arg1='arg1', arg1='arg2'
)Short calls set only values, not arguments:
self.a << fetch() # not work
a << fetch() # workGroup tuple assignment not work:
(a, b), c << fetch() # not work
a, b, c << fetch() # work
