in reply to Script to update your PPM Repositories

At work I am behind a restrictive firewall/proxy that won't let me ping outside. So I have modified your script to use LWP::UserAgent, thus checking the state of the repository via http. use strict; use warnings; use PPM::Repositories; use Net::Ping; use PPM::Repositories; use LWP::UserAgent; my $ua = new LWP::UserAgent; $ua->env_proxy if defined $ENV{HTTP_proxy}; remove_non_active_state_repositories(); add_repositories(); #remove all repositories, except the repositories that come installed +by default with ActiveState. sub remove_non_active_state_repositories { my @repositories; my $result = `ppm rep`; for (split /[\r\n]/, $result) { #parsing lines that looks like #[ 3] jenda my ($number, $repository) = $_ =~ /(\[[^>]*\]\s)(.*)/; if ($repository) { unless ($repository =~ /activestate/i) { print `ppm rep de +lete $repository` unless (/activestate/i); } } } } sub add_repositories { for ( keys %Repositories ) { my $repository = $_; my $location = $Repositories{$_}->{location}; my $domain = trim_domain($location); my $request = new HTTP::Request ("GET" => "http://$domain"); $request->proxy_authorization_basic($ENV{HTTP_proxy_user}, $EN +V{HTTP_proxy_pass}) if defined $ENV{HTTP_proxy}; my $response = $ua->request($request); if ( $response && $response->is_success ) { print "$repository is alive.\n"; print `ppm repository add $repository $location` . "\n\n"; } else { print "$repository is dead.\n"; } } } #function that trims a domain sub trim_domain { $_ = my $original_input = shift; $_ =~ s/^\s+//; #strip spaces at start of string $_ =~ s/\s+$//; #strip spaces at end of string $_ =~ s|^http://||; # strip http:// at begining $_ =~ s|/.*$||; # strip everything after the first / my $trimmed_domain = $_; unless ($trimmed_domain) { logMessage("trim_domain had a problem trimming $original_input +"); carp ("trim_domain had a problem trimming $original_input"); $trimmed_domain = "$original_input couldn't be trimmed in trim +_domain"; } return $trimmed_domain; }

[ambrus]: erix: that one actually sucks. these days people should get rid of the old notion that TeX is the only thing you can use for decent mathematics writing, because MS Office and LibreOffice have reached the
[ambrus]: level where people can more easily write as good mathematical papers in them as the people who write bad LaTeX papers usually write.
[ambrus]: Yes, for like the first twenty of its years, TeX was basically the only system that allowed you to write decent maths papers, and C++ and PHP were programming languages that sucked, etc. But times change and people have to accept that.

[Discipulus]: php does not suck anymore?
[ambrus]: Discipulus: I'm not sure, but it certainly doesn't suck as much as it's used to. it's like C++, it sucks because people still recursively learn from twenty year old PHP examples,
[ambrus]: and they try to use the obsolete features that PHP has to support only for compatibility with old scripts. C++ and PHP both have the problem that people can't forget the past, because when they google "PHP" plus the problme they want to solve, they find b
[ambrus]: ad code examples.
[ambrus]: I'm not trying to recommend PHP, but I think it has way too bad a name because of its past.
