Comment (by SimonKing):
Just for the record: The following is faster than `uncamelcase`.
{{{
#!python
cpdef inline default_match_splitter(match):
cdef str g = match.group()
return g[0]+'_'+g[1]
camel_splitter = re.compile("[a-z][A-Z]")
def new_uncamelcase(s, separator=None):
if separator is None:
return camel_splitter.sub(default_match_splitter, s).lower()
return camel_splitter.sub(lambda match:
match.group()[0]+separator+match.group()[1], s).lower()
}}}
However, since `uncamelcase` is rarely called, I will leave it.
