IFfiness - nice to know

General

Today Claude gave me code I thought would not work in Xojo, but it did.

The follow IF statement is valid. Very nice for compact coding.

var s as string
var b as Boolean = false
s = if(b,“1”,“0”) // didn't know this is valid - but it is :-)
msgbox s

But that’s practically the first example in the documentation :smiley:

If(condition, <result when expression is true>, <result when expression is false>)

Wrong thread. Fww the .child issue had zero todo with AI

I’ve known about it forever but never use it - hard to read, and can’t breakpoint on the branches.

Was happy when Xojo added this to the language natively because I’d been using my own iif function for years. Missed it when I converted over from VB.

It’s a great feature. I use ternary operators in other languages for conditional text display, so was quite happy when it was added to Xojo. I tend to avoid using it for anything other than things like:

labelValue.Text = If(myBoolean, "Something", "Something Else")

As @Julia_Truchsess said, it can make code hard to read and manage otherwise.

But it makes this a lot shorter:

If myBoolean Then
  labelValue.Text = "Something"
Else
  labelValue.Text = "Something Else"
End If

And this is very old. I don’t even remember when it was introduced. I use it extensively.

I use it a lot for hard-coded dark mode colors (which I don’t find need to be five lines)

// Set contrasting color
g.DrawingColor = if(Color.IsDarkMode, SomethingLight, SomethingDark)

I use the ternary operator much less frequently than the regular If but there are cases where it results in code that is easier to read.

I don’t generally strive for the most concise code because more often than not a more verbose version improves readability, but sometime shorter code is also clearer and its meaning easier to grasp at first sight.

I love ternary operators. I first used them in Unity, and then found it in Xojo.

There are times when I use If...Else...Endif when I need to log stuff or add a break command.
