Subject: output too verbose
Download (untitled) / with headers
text/plain 706b
I really would like CPAN.pm to be much less verbose. The purpose of feedback to the user, is that they see when things go wrong (or right). The output of CPAN.pm is so verbose (by default only?) that it is impossible for people to understand what is happening. My request is especially focused on messages like 'YAML' not installed, falling back to Data::Dumper and Storable to read prefs '/root/.cpan/prefs' Iff there is a good fallback, then why bother the user with this remark which is only understandable by Perl die-hards? My wish: please create an output-log in a file, and only show the user whether an installation was completed successfully or not, with a pointer to the (temporary) log.

I have already started working on that. Currently only two options exist for tuning verbosity: cpan[1]> o conf init /verbosity/ When CPAN.pm uses the tar command, which switch for the verbosity shall be used? Choose 'none' for quiet operation, 'v' for file name listing, 'vv' for full listing. <tar_verbosity> Tar command verbosity level (none or v or vv)? [none] When CPAN.pm loads a module it needs for some optional feature, it usually reports about module name and version. Choose 'v' to get this message, 'none' to suppress it. <load_module_verbosity> Verbosity level for loading modules (none or v)? [v] I admit it is not much but it shows where I'm trying to go.

This example is tough in that it is a very important error message for users of distroprefs. I just checked in a variant that will not bother you with this message if you have no distroprefs configured. Thanks for this suggestion. Show quoted text

It is not a good fallback. It is usually a bad fallback but the best fallback we can provide. People must take extra care in this situation. Better working suggestions welcome. Show quoted text

This will probably be possible in cooperation with CPAN::Reporter. I've openend a separate ticket (http://rt.cpan.org/Ticket/Display.html?id=29941) for this. Thanks, -- andreas

But then, people need to configure their CPAN on each system they maintain... and understand how it works. Why not simply put all about you produce now (as verbose as possible) in a seperated file per installed module... and only show failing tests directly on the screen. Using ftp://ftp.cpan.org Installing Term::ReadLine Failing tests, see ~/.cpan/install-log/Term-ReadLine-0.12.txt Installing CPAN Optional Term::ReadLine not installed Installation failed for Term::ReadLine Installation success for CPAN CPAN improvements possible: run "perl -MCPAN -e hints" Show quoted text

ok, then I understand. Maybe, the message could be changed into: CPAN preferences need YAML installed; will attempt a workaround Show quoted text

Ah... great. I'll try to give an answer, although I do not know how it works on each of the platforms. Don't expect the answer today... -- Regards, MarkOv ------------------------------------------------------------------------ Mark Overmeer MSc MARKOV Solutions Mark@Overmeer.net solutions@overmeer.net http://Mark.Overmeer.net http://solutions.overmeer.net

Note -- there are problems with this if modules prompt for user input during testing. (Annoying, but there's nothing that stops it.)

I was already aware of that aspect. -- MarkOv
