Subject: Machine-readable Module Update Report (r)
Download (untitled) / with headers
text/plain 695b
Dear Andreas J. König, Hi. This is imacat from Taiwan. I wonder if the "module update report" (r) command can output in a machine-readable format. I was trying to write a weekly checker on the updated modules. It would help a lot if the "r" command can report in a machine-readable format, since I do not want to report if everything is up-to-date, and I want to skip some modules that are not to be updated (discontinued module or version number known to be wrong). It would be better if CPAN can do it itself, of course. If not, I can write a simple wrapper if cpan "r" command can output in a machine-readable format. Please tell me if I could be of any help. Thank you.

Rather than trying to screen-scrape the results from the shell, you can use the CPAN.pm module itself to write a little program like this: use CPAN; for my $mod ( CPAN::Shell->expand("Module", "/\./") ) { next unless $mod->inst_file; # not installed next if $mod->uptodate; # up to date printf "%s\n", $mod->id; } -- You are wicked and wrong to have broken inside and peeked at the implementation and then relied upon it. -- tchrist in <31832.969261130@chthon>

Well, I have a problem here: How to avoid this message: CPAN: Storable loaded ok (v2.16) Going to read /root/.cpan/Metadata Database was generated on Wed, 07 Nov 2007 03:36:46 GMT I was running from crontab. This message will generate annoying crontab message mails for me. I have searched the document. Maybe I missed something, but I did not found a clue. Should I set $CPAN::Be_Silent = 1? $CPAN::Be_Silent does not seem to be public API. -- imacat ^_*' imacat@mail.imacat.idv.tw PGP Key: http://www.imacat.idv.tw/me/pgpkey.asc Tavern IMACAT's http://www.imacat.idv.tw/ Woman's Voice http://www.wov.idv.tw/ TLUG List Manager http://www.linux.org.tw/mailman/listinfo/tlug

A simple way to work around that would be to dup and then close STDOUT while CPAN starts up and then print your own stuff to the dup'd handle. Making a public way to shut up the CPAN shell would be handy. -- On error resume stupid

This is not simple. ^^; The simple way is $CPAN::Be_Silent = 1. Duping and closing STDOUT affects all other modules and subroutines that are printing to STDOUT, including my own and the very same script. I was planning like this in a shell script: perl -mCPAN -e'$CPAN::Be_Silent = 1; print join "", map $_->id."\n", grep $_->inst_file && !$_->uptodate && $_->id !~ /^(Test::Harness::Straps|Encode::HanExtra)$/, CPAN::Shell->expand("Module","/./");' Or echo r | cpan | grep \.tar\.gz$ | \ grep -v -E '^(Encode::HanExtra|Test::Harness::Straps)' As you can see, I cannot possibly make it simpler.

Yes. Should I file this as a new wishlist on rt.cpan.org? -- Best regards, imacat ^_*' <imacat@mail.imacat.idv.tw> PGP Key: http://www.imacat.idv.tw/me/pgpkey.asc <<Woman's Voice>> News: http://www.wov.idv.tw/ Tavern IMACAT's: http://www.imacat.idv.tw/ TLUG List Manager: http://lists.linux.org.tw/cgi-bin/mailman/listinfo/tlug

Yes please. Thanks for bringing it up, you're not the first to ask. I always had the idea that the frontend is managed by a class and the user can configure the name of the class. I was not even aware of $Be_silent. Your new ticket will hopefully lead us somewhere. -- andreas
