Export your Google Reader subscriptions to OPML

Login to your Google Reader account, then select Settings->Reader Settings->Import/Export, then "Export your subscriptions as an OPML file". Save the file somewhere.

Convert the OPML file to a SQL script

                echo "$RSSURL" | grep >/dev/null -i "podcast"
                RSSURLISPODCAST=$?
                if [ $TITLEISPODCAST -eq 0 -o $RSSURLISPODCAST -eq 0 ]; then
                        PODCAST=1
                fi
#               echo "[${RSSURL}] [${TITLE}]"   
                echo "INSERT INTO newssites (category, name, url, podcast) VALUES ('Google Reader', '"$TITLE"', '"$RSSURL"', $PODCAST);"

Run it from the same directory as the OPML file you downloaded. Direct the output to a file, e.g. google-reader-to-MythNews.sh >google-reader-subscriptions.sql

Note that if the names include special characters (e.g. ', /, », « etc) then you probably want to manually edit the resultant SQL script. Failure to do so may confuse MythNews and/or result in illegal local feed filenames.

Import the edited SQL script into your MythTV database

Probably best to backup first (though any sites you add should be trivially removeable using DELETE FROM newssites WHERE category='Google Reader';).

mysql -p mythconverg <google-reader-subscriptions.sql

Use a cron script to update all your feeds

MythNews seems to have a bug that prevents the updating of large numbers of feeds (I suspect it tries to kick off all the updates simultaneously and runs out of Qt slots), so I run this script from cron with a frequency greater than my NewsUpdateFrequency setting (default of 30 minutes).

#!/bin/sh

MYTHDBPASS="mythtv"
MYTHUSER="mythtv"

URLFILE=`mktemp /tmp/MythNews.XXXXXXXX`
touch $URLFILE

mysql -B -p${MYTHDBPASS} -u ${MYTHDBUSER} -e 'use mythconverg; select * from newssites;' | tail -n +2 >$URLFILE

cat $URLFILE | while read LINE
do
        # may need to fix path in awk statement below
        FILE=`echo "$LINE" | awk -F"\t" '{print "/var/lib/mythtv/.mythtv/MythNews/"$1}'`
        URL=`echo "$LINE" | awk -F"\t" '{print $3}'`
#       echo "Updating [$FILE] from [$URL]"
        wget --no-verbose -O "${FILE}" "${URL}"
        chown ${MYTHUSER}.%{MYTHUSER} "${FILE}"
done

NOW=`date +%s`
echo "use mythconverg; update newssites set updated=$NOW;" | mysql -p${MYTHPASS} -u ${MYTHUSER}

rm -f $URLFILE
