Re: Forcing CPAN.pm to ignore LWP/Net::FTP and use wget/lynx etc

[aufflick]

In the words of the current Australian Guinness advertising campain:

Brilliant!

I slightly modified the solution by PodMaster to make my own executable script:

#!/usr/bin/perl

use CPAN();

$CPAN_has_usable = \&CPAN::has_usable;

local *CPAN::has_usable = sub {
    return if $_[1] =~ /^(?:Net|LWP)/;
    return $CPAN_has_usable->( @_ );
};

CPAN::shell();

Only wget will work through this proxy, because it virus scans the download and does an http redirect for your "browser" to download the binary. wget is smart enough to follow this convoluted journey.

To skip lynx and the other command line tools, I hacked my MyConfig.pm in ~/.cpan/CPAN to say something like:

  'ncftpget' => q[/bin/false],
  'ftp' => q[/bin/false],
  'lynx' => q[/bin/false],

Hey - it works.

Also note that you can set your proxy config in MyConfig.pm like so:

  'http_proxy' => q[10.10.10.10:8000],
  'proxy_pass' => q[myPassWord],
  'proxy_user' => q[myUser],

Thankyou all.

Minor addition to script to avoid an annoying warning:

use CPAN ();

$CPAN_has_usable = \&CPAN::has_usable;

local *CPAN::has_usable = sub {
    return if $_[1] =~ /^(?:Net|LWP)/;
    return $CPAN_has_usable->( @_ );
};

$ENV{PERL_READLINE_NOWARN} = 1;

CPAN::shell();

It seems that if the shell is started this way rather than directly on the commandline, it complains "Can't ioctl TIOCGETP: Invalid argument" - readline etc. work anyway, so the env variable disables the warning.
