      From: seimarao@gmail.com              Hi,               Is it possible generally to arrive at a grammar from        a language or set of expressions ?               How so?              --       Sincerely,       Seima Rao.       [Depends what you mean by language. If you mean from a set of sentences,       sure, it's this:               lang ::= sentence1 | sentence2 | ...        sentence1 ::= tokens in sentence1        sentence2 ::= tokens in sentence2        ...              Of course, that's not very useful if you want to parse other sentences.              If you're asking whether it's possible to come up with a grammar that       describes the language that a human would expect the sentences or       expressions to have come from, I recall some work but it wasn't very       satisfactory. -John]              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
