?

[f.lopez, 2017/08/24 17:45:58]

This is needed for installing pip packages (for hg-git, for instance), I wasn't
sure if I put this here or where...

+
+  # https://docs.puppet.com/puppet/latest/function.html#defined
+  if defined('$package') {
+
+    ensure_resource('package', $name, merge({
+      ensure => $adblockplus::mercurial::ensure,
+      require => Package['python-dev'],
+    }, $package))
+
+    Package[$name] <- Package['mercurial']
+  }
+}
