What does the production mean?

Anything in-between quotes isn't a quote and anything between apostrophes isn't an appostrophe.


I think it can be translated as the following:
                        "\"" (~["\""])* "\""
                |       "'"  (~["'"] )* "'"

Perhaps, but what notation are you using?


but what [^"]* exactly mean?

In regular expressions, a set of characters is denoted using square brackets and the inverse set of characters is denoted by starting the set with a caret. The expression as used follows the documented conventions of regular expressions.


I hope this helps.
