Hi,
I've found a work around, inspired from Rob Williscroft :
class ReMatch(object):
"""
Object to be called :
1st time : do a regexp.match and return the answer (args:
regexp, line)
2nd time : return the previous result (args: prev)
"""
def __call__(self, regexp='', line='', prev=False):
if prev:
return self.prev_match
self.prev_match = re.match(regexp, line)
return self.prev_match
re_match = ReMatch()
if re_match(r'define\s+(\S+)\s*{$', line):
m = re_match(prev=True)
# do some logic with m
elif re_match(r'include\s+(\S+)$', line):
m = re_match(prev=True)
# do some logic with m
else
# do some logic
Hope this is efficient ... I guess yes.
A direct attribute access is cheaper than a method call, and makes for a
simpler API too:
class ReMatch(object):
match = None
def __call__(self, regexp, source):
self.match = re.match(regexp, source)
return self.match
re_match = ReMatch()
if re_match(r'define\s+(\S+)\s*{$', line):
m = re_match.match
# do some logic with m
elif re_match(r'include\s+(\S+)$', line):
m = re_match.match
# do some logic with m
My 2 cents...
