Implementation Reference
- src/index.ts:113-144 (handler)The getNowPlaying function implements the core logic to retrieve currently playing programmes across all channels by parsing XMLTV data and checking the current time against programme start and stop times.
async function getNowPlaying() { const data = await getXmltvData(); const now = new Date(); const nowPlaying = data.tv.channel.map(channel => { const currentProgramme = data.tv.programme.find(prog => { if (prog.channel !== channel.id) return false; const start = parseXmltvDate(prog.start); const stop = parseXmltvDate(prog.stop); return now >= start && now < stop; }); return { channel: { id: channel.id, name: channel["display-name"], }, programme: currentProgramme ? { title: currentProgramme.title, subtitle: currentProgramme["sub-title"], description: currentProgramme.desc, start: currentProgramme.start, stop: currentProgramme.stop, episodeNum: Array.isArray(currentProgramme["episode-num"]) ? currentProgramme["episode-num"][0] : currentProgramme["episode-num"], } : null, }; }); return nowPlaying; } - src/index.ts:272-279 (schema)Tool schema definition including name, description, and empty input schema (no parameters required).
