# This uses code derived from: |
| 13 |
# - wp-rss-aggregate.php by Kellan Elliot-McCrea <kellan@protest.net> |

# INSTALLATION: see readme.txt or <http://projects.radgeek.com/install> |
| 19 |
# |
| 20 |
# USAGE: once FeedWordPress is installed, you manage just about everything from |
| 21 |
# the WordPress Dashboard, under the Syndication menu. To ensure that fresh |
| 22 |
# content is added as it becomes available, you can convince your contributors |
| 23 |
# to put your XML-RPC URI (if WordPress is installed at |
| 24 |
# <http://www.zyx.com/blog>, XML-RPC requests should be sent to |
| 25 |
# <http://www.zyx.com/blog/xmlrpc.php>), or update manually under the |
| 26 |
# Syndication menu, or set up automatic updates under Syndication --> Settings, |
| 27 |
# or use a cron job. |
| 28 |
|
| 29 |
# -- Don't change these unless you know what you're doing... |

# Arguments: |

# ---------- |

# * $uri (string): either the URI of the feed to poll, the URI of the |
| 711 |
# (human-readable) website whose feed you want to poll, or NULL. |
| 712 |
# |
| 713 |
# If $uri is NULL, then FeedWordPress will poll any feeds that are |
| 714 |
# ready for polling. It will not poll feeds that are marked as |
| 715 |
# "Invisible" Links (signifying that the subscription has been |
| 716 |
# de-activated), or feeds that are not yet stale according to their |
| 717 |
# TTL setting (which is either set in the feed, or else set |
| 718 |
# randomly within a window of 30 minutes - 2 hours). |
| 719 |
# |
| 720 |
# Returns: |
| 721 |
# -------- |
| 722 |
# * Normally returns an associative array, with 'new' => the number |
| 723 |
# of new posts added during the update, and 'updated' => the number |
| 724 |
# of old posts that were updated during the update. If both numbers |
| 725 |
# are zero, there was no change since the last poll on that URI. |
| 726 |
# |
| 727 |
# * Returns NULL if URI it was passed was not a URI that this |
| 728 |
# installation of FeedWordPress syndicates. |
| 729 |
# |
| 730 |
# Effects: |
| 731 |
# -------- |
| 732 |
# * One or more feeds are polled for updates |
| 733 |
# |
| 734 |
# * If the feed Link does not have a hardcoded name set, its Link |
| 735 |
# Name is synchronized with the feed's title element |
| 736 |
# |
| 737 |
# * If the feed Link does not have a hardcoded URI set, its Link URI |
| 738 |
# is synchronized with the feed's human-readable link element |
| 739 |
# |
| 740 |
# * If the feed Link does not have a hardcoded description set, its |
| 741 |
# Link Description is synchronized with the feed's description, |
| 742 |
# tagline, or subtitle element. |
| 743 |
# |
| 744 |
# * The time of polling is recorded in the feed's settings, and the |
| 745 |
# TTL (time until the feed is next available for polling) is set |
| 746 |
# either from the feed (if it is supplied in the ttl or syndication |
| 747 |
# module elements) or else from a randomly-generated time window |
| 748 |
# (between 30 minutes and 2 hours). |
| 749 |
# |
| 750 |
# * New posts from the polled feed are added to the WordPress store. |
| 751 |
# |
| 752 |
# * Updates to existing posts since the last poll are mirrored in the |
| 753 |
# WordPress store. |
