[NotTaken]

I've come up with a cross platform solution:

windows instructions:

extract the contents of the attached zip to C:\ (or change path in recipe)

use this recipe:

from multiprocessing import Process, Queue
from calibre.ebooks.BeautifulSoup import *
import subprocess
import tempfile
import os

class MarketingSensoriale(BasicNewsRecipe):

    title                 = u'Marketing sensoriale'
    description           = 'Marketing Sensoriale, il Blog'
    category              = 'Blog'
    oldest_article        = 7
    max_articles_per_feed = 200
    no_stylesheets        = True
    encoding              = 'utf8'
    use_embedded_content  = False
    language              = 'it'
    remove_empty_feeds    = True
    recursions = 0
    delay = 0.0001
    auto_cleanup = False

    remove_tags_after    = [dict(name='div', attrs={'class':['article-footer']})]
    
    def get_article_url(self, article):
        return article.get('feedburner_origlink',  None)


    def preprocess_raw_html(self, raw, url):

        temp_handle, temp_path = tempfile.mkstemp()

        try:
            # nix style path
            #subprocess.check_call(["calibre-debug", "-e","/home/will/Downloads/spynner_calibre/grabber.py",url,temp_path], shell=False)
            # windows style path
            subprocess.check_call(["calibre-debug", "-e","C:\spynner_calibre\grabber.py",url,temp_path], shell=False)
        except:
            print 'spynner fetch failed'
        
        try:
            f = os.fdopen(temp_handle,'r')
            html = f.read()
        finally:
            f.close()
            try:
                os.remove(temp_path)
            except:
                print 'could not delete temp file:' + temp_path
            
        return html


    feeds          = [(u'Marketing sensoriale', u'http://feeds.feedburner.com/MarketingSensoriale?format=xml')]

I have two questions:

Can someone experienced verify that the subprocess.call in the above recipe is safe from shell injection?

Is it possible to import stuff from a calibre plugin into a script executed by calibre-debug? For example, I can't use

 import calibre_plugins.webkit_browser.spynner

.

Edit: got the answer to the 2nd question. You can add: from calibre.customize.ui import * , before the plugin import
