The default installation of CPAN.pm (started with perl5.10.0 -MCPAN -e shell) reports: ReadLine support available (maybe install Bundle::CPAN or Bundle::CPANxxl?) Why a suggestion to upgrade when there is no error/warning? Probably, the word "not" is missing from the message.

CPAN.pm has three possible sentences there: ReadLine support enabled ReadLine support suppressed and the above that you encountered. It basically means ReadLine would be enabled if you would install the bundle. It *is* available everywhere as far as I know, so I consider it good advertisement to tell the user of this feature. Different wording suggestions welcome. -- andreas

The original wording can be misinterpreted as "ReadLine support available... but I'm not using it. Nyah". How about... "ReadLine support needs Term::ReadLine." The important things to convey are: 1) You can get ReadLine support 2) How you can get it I prefer mentioning Term::ReadLine instead of Bundle::CPAN because Bundle::CPAN is like drinking from the fire hose just to get a glass of water. The enabled/suppressed wording is fine. -- Hating the web since 1994.

If it works well (enabled), or is suppressed (because? user flag?) then my preference would be to skip the texts. Only use texts which are sufficiently informative. * Michael G Schwern via RT (bug-CPAN@rt.cpan.org) [071012 05:23]: Show quoted text

Still, the question mark for non-geeks is why this line is present. Is this an error? So, what about: print "hint: improve your CPAN experience by installing Bundle::CPAN\n" if is_available $readline; The message apparently has nothing to do with ReadLine itself: in this environment (ReadLine available), there is a better CPAN. -- MarkOv ------------------------------------------------------------------------ Mark Overmeer MSc MARKOV Solutions Mark@Overmeer.net solutions@overmeer.net http://Mark.Overmeer.net http://solutions.overmeer.net

Adding "hint" in front of the hints to explain that they are, in fact, hints and not errors is the important thing here, IMHO. Possibly even coloring them differently. Also maybe show them just once. -- Ahh email, my old friend. Do you know that revenge is a dish that is best served cold? And it is very cold on the Internet!

Right now, CPAN.pm displays hints, warnings and errors all in pretty much the same way. You pointed out that this is confusing, is it an error that I don't have YAML or ReadLine support? So, the specific wording of the message is one thing, but making it clear that a message is a hint is the really important thing. -- Robrt: People can't win Schwern: No, but they can riot after the game.

My question-marks are there because the message as I suggest start with "hint". And then you reply that "hint" is useful. What I would like to achieve, is to get a message on the user experience level, not the programmer's. There are only a few programmers, and even they cannot understand the logic of the current remark. -- MarkOv

Yeah, we're having a violent agreement. -- Robrt: People can't win Schwern: No, but they can riot after the game.
