Script for importing Google Reader starred items (from starred.json file obtained from Google Checkout) into Pinboard. The import on the Pinboard website didn't work for me.

greader2pinboard.py

#!/usr/bin/env python
import json
from html2text import html2text
import pinboard
import time
import sys

username = 'pinboardusername'
password = 'secret'

def get_summary(item):
    summary = item['origin']['title'] + ": "
    try:
        summary += html2text(item['summary']['content'])
    except KeyError:
        return item['origin']['title']
    if len(summary) > 10000:
        summary = summary[0:10000] + '...'
    return summary


def get_tags(item):
    tags = []
    for tag in item['categories']:
        if not tag.startswith('user/'):
            tag = tag.replace(" ", "_")
            tags.append(tag)
    tags.append('GReader')
    return tags


def get_date(item):
    seconds = item['published']
    return time.strftime("%Y-%m-%dT%H:%M:%SZ", time.gmtime(seconds))


def greader_to_pinboard_dataset(item):
    url = item['alternate'][0]['href']
    description = item['title']
    extended = get_summary(item)
    tags = get_tags(item)
    date = get_date(item)
    return (url, description, extended, tags, date)

def main():

    file = open("starred.json")
    greader_data = json.load(file)

    pb = pinboard.connect(username, password)
    i = 0
    for (url, description, extended, tags, date) in pinboard_datasets:
        print "Item %i" % i
        pb.add(url, description, extended, tags, date)
        print(url, description, extended, tags, date)
