I assert it's easier to write:
start_new_thread( this_func )
def thrA():
normal_suite()
than
def thrA():
normal_suite()
start_new_thread( thrA )
If you don't, stop reading. If you do, accomplish it like this:
@decwrap( start_new_thread, Link, ( 2, 3 ) )
def anonfunc( a, b ):
print( a, b )
where 'Link' replaces the following func, plus in keywords too:
@decwrap( Thread, None, target= Link, args= ( 2, 3 ) )
def sampleth( a, b ):
print( a, b )
sampleth.start()
sampleth.join()
'Link' is a pseudo-constant.
Link= object()
@decwrap follows.
def decwrap( func, *ar, **kwar ):
def predec( func2 ):
ar2= list( ar )
while Link in ar2:
ar2[ ar2.index( Link ) ]= func2
kwar2= kwar.copy()
for k, v in kwar2.items():
if v is not Link: continue
kwar2[ k ]= func2
ret= func( *ar2, **kwar2 )
return ret
return predec
Further applications:
@decwrap( button.bind, "<Key-X>", Link )
def anonfunc():
print( 'Key X pressed' )
Optional stylism for readability:
@decwrap( start_new_thread, ~Link, ( 2, 3 ) )
@decwrap( Thread, None, target= ~Link, args= ( 2, 3 ) )
@decwrap( button.bind, "<Key-X>", ~Link )
where 'Link' is:
class NegMarking:
def __invert__( self ): return self
Link= NegMarking()
