# RSS Display Script by Bill Woodford ([email protected]) v1.0
#
# This script is designed to output story titles for most any RSS Feed.
#
# This script depends on curl.  Please ensure it is installed and in your $PATH
# Gentoo: emerge -av net-misc/curl
# Debian: apt-get install curl
# Homepage: http://curl.haxx.se/
#
# Usage:
# .conkyrc:    ${execi [time] /path/to/script/conky-rss.sh URI LINES TITLENUM}
#    URI = Location of feed, ex. http://www.gentoo.org/rdf/en/glsa-index.rdf
#    LINES = How many titles to display (default 5)
#    TITLENUM = How many times the title of the feed itself is specified, usually 1 or 2 (default 2)
#
# Usage Example        
#        ${execi 300 /home/youruser/scripts/conky-rss.sh http://www.foxnews.com/xmlfeed/rss/0,4313,1,00.rss 4 2}

#RSS Setup - Don't change unless you want these values hard-coded!
uri=$1                            #URI of RSS Feed
lines=$2                        #Number of headlines
titlenum=$3                        #Number of extra titles

#Script start
#Require a uri, as a minimum
if [[ "$uri" == "" ]]; then
    echo "No URI specified, cannot continue!" >&2
    echo "Please read script for more information" >&2
else
    #Set defaults if none specified
    if [[ $lines == "" ]]; then lines=5 ; fi
    if [[ $titlenum == "" ]]; then titlenum=2 ; fi

    #The actual work
    curl -s --connect-timeout 30 $uri |\
    sed -e 's/<\/title>/\n/g' |\
    grep -o '<title>.*' |\
    sed -e 's/<title>//' |\
    head -n $(($lines + $titlenum)) |\
    tail -n $(($lines))
fi
