the code he's referring to doesn't seem to use that construct anymore, so
it's not obvious what "dejavu.icontains" etc really is, but assuming they're
strings, the following is a reasonable lambda-free alternative:
class xforms:
def icontains(self, x, y): return x + " Like '%" + y[1:-1] + "%'"
def icontainedby(self, x, y):
# icontainedby body goes here instead of in a separate function
def istartswith(self, x, y): return x + " Like '" + y[1:-1] + "%'"
def iendswith(self, x, y): return x + " Like '%" + y[1:-1] + "'"
def ieq(self, x, y): return x + " = " + y
def now(self): return "Now()"
def today(self): return "DateValue(Now())",
def year(self, x): return "Year(" + x + ")"
def dispatch(self, tag, *args):
return getattr(self, tag)(*args)
here's another "reasonable example", btw:
http://groups-beta.google.com/group/comp.lang.python/msg/11462b89a490a6ac
this too could be rewritten to use a class (combined with re.sub and
a callback, most likely).
