""" CommentAPI provides support for Joe Gregario's CommentAPI . To use it, place it your plugins directory and make sure that you define py['commentAPI_urltrigger'], which is the URI to be used for talking to the commentAPI. Be sure that you have comments.py installed You must also add the commentAPI tags to your RSS 2.0 feed. The best way to do this is to add an XML namespace declaration to the rss element: xmlns:wfw="http://wellformedweb.org/CommentAPI" Then inside your RSS items you need to add a wfw:comment element: $base_url/###commentAPI###/$file_path where ###commentAPI### is the value of commentAPI_urltrigger %<--------------------------------------------------------- py['commentAPI_urltrigger'] = "/commentAPI" %<--------------------------------------------------------- """ import os, os.path from Pyblosxom import tools def cb_start(args): request = args["request"] config = request.getConfiguration() logdir = config.get("logdir", "/tmp") logfile = os.path.normpath(logdir + os.sep + "commentAPI.log") tools.make_logger(logfile) def verify_installation(request): config = request.getConfiguration() retval = 1 # all config properties are optional if not config.has_key('commentAPI_urltrigger'): print("missing optional property: 'commentAPI_urltrigger'") return retval def cb_handle(args): """ @param args: a dict of plugin arguments @type args: dict """ request = args['request'] pyhttp = request.getHttp() config = request.getConfiguration() urltrigger = config.get('commentAPI_urltrigger','/commentAPI') path_info = pyhttp['PATH_INFO'] if path_info.startswith(urltrigger): try: from Pyblosxom.entries.fileentry import FileEntry import os, sys pi = path_info.replace(urltrigger,'') if pi == '': sys.exit("CommentAPI.cgi expects to receive an RSS item on standard input") datadir = config['datadir'] path = os.path.join(datadir, pi[1:]) data = request.getData() filename = '' ext = tools.what_ext(data['extensions'].keys(),path) filename = os.path.normpath('%s.%s' % (path, ext)) entry = FileEntry(request, filename, datadir ) data = {} data['entry_list'] = [ entry ] commentString = sys.stdin.read() if commentString == None: sys.exit("CommentAPI expects to receive an RSS item on standard input") try: from xml.dom.minidom import parseString from xml.parsers.expat import ExpatError commentDOM = parseString(commentString) except ExpatError, ee: sys.exit("The RSS Item you supplied could not be parsed.\nThe error occured at line %d, column %d" % (ee.lineno,ee.offset)) def dictFromDOM(dom, data, field, default=''): """ Fill in a field in dict with the content of a element in the dom TODO: epydoc """ value = dom.getElementsByTagName(field) if len(value) == 1: data[field] = value[0].firstChild.data else: data[field] = default # use dictFromDOM to fill in a dict with the stuff in the comment cdict = {} dictFromDOM(commentDOM, cdict, 'title') dictFromDOM(commentDOM, cdict, 'author') dictFromDOM(commentDOM, cdict, 'link') dictFromDOM(commentDOM, cdict, 'source') # force an integer data stamp -- not in keeping with RFC 822, # but neither is RSS import time cdict['pubDate'] = str(time.time()) dictFromDOM(commentDOM, cdict, 'description') # must be done after plugin initialization from comments import writeComment # write the comment (in the dict) writeComment(request, config, data, cdict, config['blog_encoding']) print "Content-Type: text/plain\n" print "OK" except OSError: print "Content-Type: text/plain\n" print "An Error Occurred" return 1 else: return 0
