Cal EXT3 - understanding transforming

sdetweil

@_V_ said in Cal EXT3 - understanding transforming:

ev.title.search

search() searches the string for the specified characters and IF those characters are found, it returns the position of the text in the string…(0= 1st char/start of string). if NOT found it returns -1

this is a javascript string function

there is also startsWith() and endsWith()
search() = contains

the code could have used includes()

The includes() method of String values performs a case-sensitive search to determine whether a given string may be found within this string, returning true or false as appropriate.

if you wanted case insensitive, you would do
ev.title.toLowerCase().includes(‘john’)

@_V_ transforming, you must ALWAYS return the event, modified or not

Hello Sam

Thanks for the input.
Ok now what would this search method mean for “title”

Like, what is it the case of the EXT3 cal module?
It says “title”?
Anybody knows about my last question for icon change too?

Thanks

@_V_ from his readme

@_V_ what do you mean for title? We just searched title
If you want to change it. Then do that

ev.title=‘new string’

Same with symbol

sdetweil

@_V_ you can change any property of the event

I get the idea but since Im quite new to this, I cant follow completely.
Again the example

eventTransformer: (ev) => {
  if (ev.title.search("John") > -1) ev.color = "blue";
  return ev;
};

Now you told me, “search” is a look up in form of “if contains” - this means if it contains the value, it will give out a value bigger than -1 and the effect will be set; other wise it will return -1 and the event stays unedited, correct?

This would also mean, I have to set up every possible event title class inbefore.
If I want to change/assign a specific symbol is a thing I dont understand.
I use the Iconify function from the module - do I have to put in a link to the desired symbol now or what is it I have to enter?
I could also imagine that I have to download the symbols and put in a directory to make the module be able to access them?

Thanks a lot

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; 
},
