Adding X minutes to a timestamp for countdown

Hey @Frisky Dog!

Nightbot's $(countup) and $(countdown) work best with time formatted as follows: MM DD YYYY HH:mm:ss, therefore this is the format I'll use, but if you really want to keep using your format, the same idea applies.

Basically, what we have to do is convert the hours and minutes to minutes, add 90 minutes and convert the whole thing back to hours and minutes:

$(eval t=`$(urlfetch LINK)`.match(/\d+/g); m=t[3]*60+t[4]+90; t[3]=Math.round(m/60); t[4]=Math.round(m%60); $(countdown ${t[0]} ${t[1]} ${t[2]} ${t[3]}:${t[4]}:${t[5]} TIMEZONE)) 

You may encounter issues when you're between 0 and 90 minutes from a new day, but that should be about it.

.match(/\d+/g) — matches all the numbers and put them in an array, given that the format is
MM DD YYYY HH:mm:ss, and that each of them are numbers we'll have:
• t[0] = MM
• t[1] = DD
• t[2] = YYYY
• t[3] = HH
• t[4] = mm
• t[5] = ss

Thanks @Polar Cat! I am going to give this a whirl.
After a lot of trial and error I managed to do the "simple" task of creating a second timestamp 90 minutes ahead of now but the ultimate goal was working with a single timestamp instead of two. Changing the format should be no problem at all. I don't recall what led me to use the one I was, I thought it was something from the Nightbot docs.

JS and I don't get along well. Regex won't return my calls either. 😄

Oh right, that's my bad, it was late and my brain was foggy, I forgot that Nightbot will execute/replace all the variables before the code executes, so it calls $(countdown) before it computes t. The solution would be to use two commands, the second being the alias of the first one:

$(eval t=`$(urlfetch LINK)`.match(/\d+/g); m=t[3]*60+t[4]+90; t[3]=Math.round(m/60); t[4]=Math.round(m%60); `${t[0]} ${t[1]} ${t[2]} ${t[3]}:${t[4]}:${t[5]} TIMEZONE`)
​
$(countdown $(query))

But since it's on a timer with a $(countup) as well, the solution would be something like this:

$(eval t=`$(urlfetch LINK)`; a=t.match(/\d+/g); m=a[3]*60+a[4]+90; a[3]=Math.round(m/60); a[4]=Math.round(m%60); `${t} ${a[0]} ${a[1]} ${a[2]} ${a[3]}:${a[4]}:${a[5]} TIMEZONE`)

And then have the timer call an alias command with that code in it:

We started $(countup $(1) $(2) $(3) $(4) $(9)) ago, and we have $(countdown $(5) $(6) $(7) $(8) $(9)) left.
