I see perlbrew install
can take a stable
argument to install the latest, but I would like to get the latest stable version number to check against before installing.
How can I get the version number of the latest stable perl using perlbrew?
perlbrew available | perl -e'
my @available_perls = <>;
s/^\s+|\s+\z//g for @available_perls;
my ($latest_ver, $latest_minor);
for my $cand (@available_perls) {
my ($ver, $minor) = $cand =~ m/^perl-(5\.(6|8|[0-9]+[02468])\.[0-9]+)$/
or next;
($latest_ver, $latest_minor) = ($ver, $minor)
if !defined $latest_minor
|| $latest_minor < $minor;
}
die "Can\x27t determine latest stable Perl release\n"
if !defined $latest_ver;
print "$latest_ver\n";

Effectively lifted straight out of App::perlbrew.
If you had App::perlbrew installed, you could use the following:
/path/to/perl/with/module/perl -MApp::perlbrew -e'
my $latest_ver = App::perlbrew->new->resolve_stable_version;
print "$latest_ver\n";
