I propse "-g" (mnemonics: gobble, grab, gulp). Yes, please. I have taught Perl for a living, and having a single option for this would making teaching one-liners much easier. The current -0 option has the flexibility of being completely general, but that generality gets in the way of learning the most common cases: you need to understand the concepts of record separators, octal, and then a non-octal token. There are now several messages of support and none against, so I think you may now proceed to writing and submitting an RFC.

One of the advantages I see of such a flag is *not* needing to think about it at the level of the record separator (unless you want to). The flag would cause Perl to read in a whole file/all of standard input at once. That it would do this by setting the input record separator to a specific value is *how* it does that, but not *why* you would use the flag. > Then again, the general move towards long opts It sounds like there are many in favour of long options. An RFC on that matter may be worthwhile. But that isn't a reason to delay *this* RFC for something else which may or may not happen. SmylersThread Previous | Thread Next
