Started with some keywords in word (just as a notepad for myself), some pieces on code I knew was working.
The goal was to read a TXT file
Find the line that corresponded with today’s date, if the month (DD.MM.YYYY) was todays mouth, then search for today’s date.
If today’s date was found, display the second text.
Separate the text and use it as a variable, filter out the "//"
But each word should have a specific colour.
To make it more complex, it should also give you a notice the day before, in a different colour.
And of course show you 3 different icons, for 3 different states.
It's sort of a "GarbageCalendar (amateur) lua script"
Requires
- A text file, made up in Excel, saved as Unicode TXT file, transferred to the LUA script folder.

No waste
The day before
Today
I know there’s a lot to do with the design, the goal was just to see what's possible to do with simple tools.
The code is not perfect.
Might be better options in DeVent, but I got better working with LUA, maybe more articles online?(for Copilot to read)
And for the TXT file, it takes 5 >10 minuttes to edit once a year..
