The code has comment delimeters as an argument and will also strip ''nested'' block comments.
<lang python>def _commentstripper(txt, delim):
'Strips first nest of block comments'
deliml, delimr = delim
out = ''
if deliml in txt:
indx = txt.index(deliml)
out += txt[:indx]
txt = txt[indx+len(deliml):]
txt = _commentstripper(txt, delim)
assert delimr in txt, 'Cannot find closing comment delimiter in ' + txt
indx = txt.index(delimr)
out += txt[(indx+len(delimr)):]
else:
out = txt
return out
def commentstripper(txt, delim=('/*', '*/')):
'Strips nests of block comments'
deliml, delimr = delim
while deliml in txt:
txt = _commentstripper(txt, delim)
return txt</lang>
