Text per week

retroflex

Does anyone know if there is a module that let’s you show a different text each week? My son is learning letters in school and each week they have a certain letter, like this:

week 38: R
week 39: E
week 40: P
…

My though was to show this week’s letter on my mirror.

@retroflex
As far as I know, there is nothing like that.
But I think it could be easily developed.
with moment.js library, you can easily get the order of the current week.

const letterOfWeek = ["", "", "A", ... "R", "E", "P", ...],
var curWeekNumber = moment().week() //will return 1~52. You can use `isoWeek()` also.
var letterOfThisWeek = letterOfWeek[curWeekNumber]

This is just an idea, anyway, I believe you can make a simple module to display this.

@retroflex
Here. not fully tested.

Module.register("letterOfWeek",{
  defaults: {
    letterOfWeek: {
      "default": "?",
      "38": "A",
      "39": "B",
      "40": "C",
    },
    updateInterval: 1000*60*60*3, // refresh per 3 hour.
  },
  getScripts: function() {
    return ["moment.js"]
  },
  getStyles: function() {
    return ["letterOfWeek.css"] // You need to parepare your own css.
  },
  getDom: function() {
    var getLetter = ()=> {
      var thisWeek = moment().week()
      var letter = (this.config.letterOfWeek.hasOwnProperty(thisWeek))
        ? this.config.letterOfWeek[thisWeek]
        : this.config.letterOfWeek["default"]
      return letter
    }
    var dom = document.createElement("div")
    dom.innerHTML = getLetter()
    dom.classList.add("letterOfWeek")
    return dom
  },
  notificationReceived: function(noti, payload) {
    if (noti == "DOM_OBJECTS_CREATED") {
      this.refresh()
    }
  },
  refresh: function() {
    this.updateDom()
    setTimeout(()=>{
      this.refresh()
    }, this.config.updateInterval)
  }
})

@Sean Thanks a lot! My thought was to make a module, but wanted to check first if one existed. And now you did the work for me I will try it out tonight. Maybe even upload it so others can download it.

So a lot later I finally managed to make a module out of this:
