GR2WP – Google reader shared items till WordPress

I kategorin Tips så delar jag med mig av intressanta inlägg som jag hittat via mina RSS-flöden i Google Reader.

Det finns flera andra som har liknande funktion på sina bloggar, de använder då exempelvis FeedWordPress, SharedItems2WP eller WP-o-Matic. Av olika anledningar passade ingen av dessa lösningar mig perfekt, mest för att jag ville ha full kontroll över flödet och för att det var så länge sen jag programmerade i perl …

Som jag nyss avslöjade, så skrev jag alltså ett perl-script som hämtar min shared items-feed från google reader (via XML::Atom::Syndication::Feed) och sen trycker jag in en post med de senaste bloggtipsen i WordPress (via XMLRPC::Lite).

Effekten blir den här.

Gå till Google reader, hitta ett intressant inlägg och välj ”Share with note”.

Share with note i google reader
Share with note i google reader

Lägg till en anteckning och spara.

Kör sen perlscriptet gr2wp.pl (Google Reader To WordPress).
Då skapas ett WP-inlägg med alla nya utdelade bloggposter.

Här kommer perlscriptet. Du får gärna använda och modifiera det helt fritt. Jag har utgått från ett script som postade google-reader shared items till delicious.

För enkelhetens skull kör jag perl-scriptet en gång om dagen, via crontab.
