I've written a parser function to scrape a website looking for the newest
version of a package I want loaded on my laptop. I'm getting really wonky
results.
Here's the function in all its glory completely un-edited:
require 'net/https'
require "rexml/document"
require 'sanitize'
module Puppet::Parser::Functions
newfunction(:latest_makehuman_unstable, :type => :rvalue, :doc => <<-EOS
This function interrogates the MakeHuman nightly builds site to detect
the newest version of MakeHuman for download.
Returns the deb package name
EOS
) do |args|
stripped=Sanitize.clean(fetch_download_list())
lines = stripped.split(/\n/);
deblist=lines.grep(/x-debian/)
wanted = deblist.last.split(/.deb/).first + ".deb"
end
end
def fetch_download_list
begin
http = Net::HTTP.new("download.tuxfamily.org",80)
http.use_ssl = false
http.start do |http|
req = Net::HTTP::Get.new("makehuman/nightly/",
{"User-Agent" =>
"juretta.com RubyLicious 0.2"})
response = http.request(req)
response.body
end
end
It is supposed to return the name of the latest .deb file listed on the
website. This (I thought) should be a no-brainer. Instead I get this:
Error: Could not retrieve catalog from remote server: Error 400 on SERVER:
undefined local variable or method `resp' for
Scope(Class[Apps::Modelling::Makehuman]):Puppet::Parser::Scope at
/etc/puppet/environments/production/modules/apps/manifests/modelling/makehuman.pp:41
on node saltycowdawg.tfl.berghold.net
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run
The variable it is complaining about does not exist! What the heck?
Any thoughts?
