Cal EXT3 - understanding transforming

If I search this field, and find ‘John’
Then
I change the event color
ev.color=

You could change to symbol the same way
ev.symbol=. Whatever symbol name

You are writing code here
The filter routine sees every event, one at a time

You can have more than one if stmt
Can use if else if else, use a switch /case logic block

@sdetweil Sam good evening

I wonder how to set up multiple ev transformations in one config.

I got working

{ 
eventTransformer: (ev) => {
if (ev.title.search("Geburtstag") > -1) {ev.color= "#ff00ff"; };
return ev; },

But putting another one to it is puzzling me. I tried different methods, but cant get it done.
When I simply put a second complete command after the first, like this:

{ 
eventTransformer: (ev) => {
if (ev.title.search("Arzt") > -1) {ev.color= "#ff0000"; };
return ev; },

it will just negate the first applied effect from birthday and uses this effect instead on the named events.
Can you help me out please?

all in one… there is only ONE eventTransformer, it has to do ALL the work for ALL events

I used else if here… if it matched the first, there is no reason to check again

eventTransformer: (ev) => {
     if (ev.title.search("Geburtstag") > -1) {ev.color= "#ff00ff"; }
     else if (ev.title.search("Arzt") > -1) {ev.color= "#ff0000"; };
return ev; 
},

@_V_ as you might have overseen you can not only check several conditions (as Sam (@sdetweil ) suggested) - separated by else or not but you can make several changes to the same event at one check.

e.g.:

eventTransformer: (ev) => {
  if (ev.title.search("Restmüll & Papier & Gelber Sack") !== -1) {ev.isFullday = [true], ev.title = "Alle Tonnen", ev.symbol = [ "fa-regular fa-trash-can" ], ev.color = "fuchsia"}
  if (ev.title.search("Therapie") !== -1) { ev.title = "Sitzung", ev.symbol = [ "fa-solid fa-mug-hot" ], ev.color = "Forestgreen"}
return ev
   			  }, // end Eventtransformer

In the above example you can see

the modification of the color (as you already had identified,
the change of the kind of event (from “scheduled” to “Fullday-Event”)
the assignment of a different symbol (with font-awesome-symbols: double check their web-page, keep in mind that only the “STANDARD” (non-payed) versions will be shown in Magic Mirror) and
the change of the title of the event.

Hope this helps.
Good luck!

@rkorell his issue is not knowing JavaScript language and syntax

rkorell

@sdetweil Yes :-)
therefore I thought a detailed example would be beneficial …
Warmest regards,
