A simple CLI for show tracking

const fs = require('fs')

const BASE = `${process.env['HOME']}/.tvcl`
const WATCH_FILE = `${BASE}/watch.json`

let cache = undefined

function read() {
  if (fs.existsSync(WATCH_FILE)) {
    cache = JSON.parse(fs.readFileSync(WATCH_FILE))
  } else {
    cache = {}
  }
}

function watch(epId) {
  if (!cache) {
    read()
  }
  cache[epId] = true
}

function save() {
  if (!cache) {
    read()
  }
  fs.writeFileSync(WATCH_FILE, JSON.stringify(cache))
}

function isWatched(e) {
  if (!cache) {
    read()
  }
  const id = e['id'][0]
  return !!cache[id]
}

module.exports = { watch, save, isWatched }
