A problem for your consideration:
We are given a tuple of delimiter string pairs to quote or comment
text, possibly over multiple lines. Something like this:
delims = (('"', '"'), ("'", "'"), ('#', '\n'), ("\*", "*\),
('\\', '\n') ...)
These may be nested.
Here's the problem: Determine is the string S appears *outside* or
*inside* any such quotation.
You would have to define what should happen in a case where you have
more than one single/double-quote delimited items on the same line:
do("this", "and", "that")
Each of them is considered quoted and thus if S appears within
any of them it is "inside".
should it return true or false when testing for 'this", "and",
"that'? (it is within double-quotes)
False.
And what should happen with mismatched quotes?
do("th/*is", "and", "th*/at")
Match pairs as usual, and let the remaining unterminated quote run on.
It would also help to have a proposed function signature for the
functionality you want. Something like
def inside_quote(s, corpus, delims=delims):
I'd prefer:
def quoted (s, corpus, delims=delims, domain=outside)
