Highrise Backup

with 2 comments

I no longer use Highrise, but when I did, I used this Python script to back up my contacts. Hope it’s helpful to someone.

Connecting Google Reader and podget

with 2 comments

For some time, I’ve had a Perl script that runs regularly, backing up my Google Reader subscriptions using the standard OPML format:

#!/usr/bin/perl
#
# Usage:
#  backup-google-reader-opml file-to-write-to.opml google.user.name@domain google-password
 
use strict;
use warnings;
 
use WWW::Mechanize;
 
my $mech = WWW::Mechanize->new();
 
$mech->get("http://reader.google.com")
    or die "Cannot reach Google Reader Homepage";
 
$mech->submit_form(
    form_number => 1,
    fields =>
    {
        Email => $ARGV[1],
        Passwd => $ARGV[2]
    }
)
    or die "Cannot submit form";
 
$mech->get("http://www.google.com/reader/subscriptions/export");
$mech->save_content($ARGV[0]);

However, I recently wrote another script (this time Python) that then takes this OPML, parses out all the URLs that are tagged with ‘podcast’, and outputs a serverlist file for podget (an automated console-based podcast downloader). This enables me to subscribe to a podcast in Google Reader, and have the podcast automatically added to the download list. The script looks like this:

#!/usr/bin/python
#
# Pass in the OPML file as the first command-line parameter. Will output the
# podget serverlist on stdout.
 
import re
import sys
import xml.dom.minidom
 
doc = xml.dom.minidom.parse(sys.argv[1])
 
body = doc.getElementsByTagName("body")[0]
 
p = re.compile('^\W+')
 
for outline in doc.getElementsByTagName("outline"):
    if outline.getAttribute("text") == "podcast":
        for subOutlines in outline.getElementsByTagName("outline"):
            title = subOutlines.getAttribute("title")
            title = p.sub("", title)
            print subOutlines.getAttribute("xmlUrl") + " NoCategory " + title

Feel free to use and adapt to your needs.
