I've always liked the algorithm used by the textwrap module that Erick mentions: starting with the second line (i.e. the first one after the triple-quote), dedent all lines uniformly until the last one. The only thing it's missing IMHO is that it should also remove the first line if it's blank (thus eliminating bugs such as the one in the webserver). Works nicely for docstrings, etc. The problem that arises of course is what to do with mixed tabs / spaces; I'd say just dedent until mismatched indentation is encountered. Another idea I like is how O'Caml's escaped-end-of-line means "elide the newline and all leading whitespace on the next line". Very convenient for wrapping long lines. I'd suggest this behavior for both docstrings and normal strings in Felix. > In this case .. attempts to make the code look nice > turn out to cause a bug.

It's very consistent in a do-what-I-mean fashion, and it's consistent with the O'Caml-style end-of-line escapes too (where the trailing whitespace is needed). If someone really wants trailing whitespace for some other reason, they should really just be using normal strings (which, with end-of-line escapes, are well-suited to entering precise string data). I think treating triple-quotes as a do-what-I-mean construction, and single-quotes as do-what-I-say, will generate the least amount of "surprise" for people coming from other languages. - Chris ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
