[Perlchamp]

i could send you the three files (node_helper.js, MMM-Perlchamp.js, birthdays.csv) via email ?

@Perlchamp said in read csv-data and put it in an array:

  		if(birth_date_moment.startOf('day').isSameOrAfter(now.startOf('day')) &&
     	  birth_date_moment.startOf('day').isSameOrBefore(birthday_time_window.startOf('day'))) {

yes it only shows for today+some possible offset… I said u had to fix that to do month comparison

[Perlchamp]

shame on me, sorry for that. now it’s changed to:

if(birth_date_moment.startOf('month').isSameOrAfter(now.startOf('month')) &&
					birth_date_moment.startOf('month').isSameOrBefore(birthday_time_window.startOf('month'))) {

nothing changed, i have configured the terminal-window to scroll about 3000 (!) lines, but can’t see the beginning …

[sdetweil]

@Perlchamp redirect the terminal window to a file and edit that

do this in the code

				// if the date is the same or later, don't use time of day
			 	//if(birth_date_moment.startOf('day').isSameOrAfter(now.startOf('day')) &&
                                //  birth_date_moment.startOf('day').isSameOrBefore(birthday_time_window.startOf('day'))) {
			   	*/
			   	if( birth_date_moment.month() == now.month() ){

[Perlchamp]

done, it’s frozen now. must restart …

[Perlchamp]

question:
in the

socketNotificationReceived: function(notification, payload) {
		if(notification === "HAVEDATA") {
			var self = this;
               ...

payload should be the variable in which the jsonString is saved ?

[sdetweil]

@Perlchamp it has the jsonObj from the node_helper

u can call it anything, its just a name

so, if you put a stop right on the var self = this
and then cursor over the work payload in

function(notification, payload)

it will show you that object content, and u can go up and click on parts to make them expand to examine the contents

[Perlchamp]

ok, there is a light at the end of the tunnel:

[sdetweil]

code was changed to add ages

in getDom()

			for(var name of this.active_birthdays[birthday]) {
				var m = document.createElement("div");
				Log.log("BIRTHDAY >> " + birthday);
				Log.log("NAME >> " + name);
				m.innerText = birthday + " " + name;
				wrapper.appendChild(m);
			}

now is

			for(var person of this.active_birthdays[birthday]){
				var m=document.createElement('div')
// create your table row here				
				m.innerText=birthday+ ' '+ person.name+' age='+person.age
				wrapper.appendChild(m)					
			}

[Perlchamp]

great, thanks !
to your information:
there are NO semikolons in your posted code. within them it goes !

[sdetweil]

@Perlchamp end of line ; are not required… I cut/pasted that code out of the running module

[Perlchamp]

without i have a black screen, with everythings fine.
another information:
age must be +1 but i think i will solve this alone. if not i’m too stuipid for this all :-)
so i can create my table now. but i see:
people who has birthday the same day:
date should be displayed once, and the names in the same , separated by

[sdetweil]

@Perlchamp ok, I think you can fix those… age is a date diff()… add to results

edit: age needs more work that just number… because they were comparing MONTH, but age was exact days.

so I change my bd to may, but TODAY I am 68… in may i WILL BE 69 (in the future)
so if TODAY or before, do NOT add one, if tomorrow or after (in the month) add 1

[Perlchamp]

i think, too. thanks very much, sam. I don’t know how to thank you Thank you very much !
you’re great !
and it is up to you whether you publish this module. I will not adorn myself with foreign feathers!

[sdetweil]

@Perlchamp its not my module… its yours…

[sdetweil]

@Perlchamp see how interesting ‘just a birthday list’ can be! and u still have styles to apply etc

[Perlchamp]

I do not think so. I could never answer questions about any problems …
i did:

... age='+(person.age + 1);

the styles you could get from me, no problem. it’s just fair, isn’t it ?

[sdetweil]

@Perlchamp should be wrong for people with birthday yesterday
