ruby-extensions - where do i get them - for opensuse 13.1

English Install/Boot/Login
#1

love opensuse and all that things - but today i have another serious quesiton

run opensuse with version 13.1

where do i get the following ruby modules / ingedients to run this programme…



require 'open-uri'
require "net/http"
require 'rexml/document'

def query_overpass(object_type, left,bottom,right,top, key, value)
   base_url = "http://www.overpass-api.de/api/xapi?"
   query_string = "#{object_type}[bbox=#{left},#{bottom},#{right},#{top}]#{key}=#{value}]"
   url = "#{base_url}#{URI.encode(query_string)}"
   resp = Net::HTTP.get_response(URI.parse(url))
   data = resp.body
   return data and so on and so forth

do i find them in a repo or should i install it with / trough the software-installation-programme…

love to hear from you

Those 3 are part of the standard ruby package:

wolfi@amiga:~> rpm -ql ruby20 |egrep "(open-uri|net/http|rexml/document)"
/usr/lib64/ruby/2.0.0/net/http
/usr/lib64/ruby/2.0.0/net/http.rb
/usr/lib64/ruby/2.0.0/net/http/backward.rb
/usr/lib64/ruby/2.0.0/net/http/exceptions.rb
/usr/lib64/ruby/2.0.0/net/http/generic_request.rb
/usr/lib64/ruby/2.0.0/net/http/header.rb
/usr/lib64/ruby/2.0.0/net/http/proxy_delta.rb
/usr/lib64/ruby/2.0.0/net/http/request.rb
/usr/lib64/ruby/2.0.0/net/http/requests.rb
/usr/lib64/ruby/2.0.0/net/http/response.rb
/usr/lib64/ruby/2.0.0/net/http/responses.rb
/usr/lib64/ruby/2.0.0/net/https.rb
/usr/lib64/ruby/2.0.0/open-uri.rb
/usr/lib64/ruby/2.0.0/rexml/document.rb

So you shouldn’t have to install anything special…

Well, I have absolutely no experience with ruby and installing gems.

But maybe you should try to install them via openSUSE rpms?

rubygem-mysql and rubygem-mysql2 are part of the standard distribution:
http://software.opensuse.org/package/rubygem-mysql
http://software.opensuse.org/package/rubygem-mysql2

rubygem-sequel is available from the devel:language:ruby:extensions repo:
http://software.opensuse.org/package/rubygem-sequel

hello dear wolfi many many thanks for all the help!!!

while running this code i get the following results



import urllib
import urlparse
import re

url = "http://search.cpan.org/author/?W"
html = urllib.urlopen(url).read()
for lk, capname, name in re.findall('<a href="(/~.*?/)"><b>(.*?)</b></
a><br/><small>(.*?)</small>', html):
    alk = urlparse.urljoin(url, lk)

    data = { 'url':alk, 'name':name, 'cname':capname }

    phtml = urllib.urlopen(alk).read()
    memail = re.search('<a href="mailto:(.*?)">', phtml)
    if memail:
        data'email'] = memail.group(1)

    print data

see the results…

Why are you still trying to harvest email addresses from cpan?
Do you plan on spamming people?
