Re: [gentoo-user] Heads-Up sys-lib/com_err breaks Apps

Here's a perl script to display the einfo lines of packages to
be merged.  Just run it with the same options you will use for
emerge.  Example:

  einfo -uDN world >einfo.txt
  emerge -uDN world
  less einfo.txt

You will probably want to save the output to refer to after
emerging.

Enjoy,
Roy

#!/usr/bin/perl

# this script will run emerge with the given command line options plus
# "--pretend".  It will then grep all of the packages to be merged looking
# for einfo lines to display.

$portage = '/usr/portage';
$emerge = "emerge @ARGV --pretend";

open(EMERGE, "$emerge|") || die "unable to open $emerge\n";
while(<EMERGE>) {
        if(/\[[^\]]+\]\s+(\S+)\/(\S+)\-(\d\S*)\s/) {
                findInfo($1,$2,$3);
        }
}
close(EMERGE);

exit 0;

sub findInfo
{
        local ($package,$name,$ver) = @_;
        local $pkgDir = "$portage/$package/$name";
        local $ebuild = "$pkgDir/$name-$ver.ebuild";
        print "$ebuild\n";
        if(-T $ebuild) {
                open(EBUILD, "<$ebuild") || warn "unable to read $ebuild\n";
                while(<EBUILD>) {
                        if(/(einfo.*)$/) {
                                print "  $1\n";
                        }
                }
                close(EBUILD);
        }
        print "\n";
}
