On the left you have Elvis Presley, while on the right there's the so-called Elvis operator
been programming since 2008. the fuck is an elvis operator?
Been programming since the 80s, ditto.
Ternary if?then:else
gotacha. i've only ever heard them called ternaries. maybe i'm old. maybe i'm too young. definitely one of the two
It specifically refers to this shorthand ?: that works like this:
$value = $thing_that_could_be_truthy ?: 'fallback value';
# same as
$value = $thing_that_could_be_truthy ? $thing_that_could_be_truthy : 'fallback value';
The condition is also the value if it is truthy
I never heard it called the Elvis operator! Thanks!
It's because if you turn it 90° to the right, it looks like Elvis' hair with two eyes underneath!
I saw it the other way, with the question mark as the curl of his lip.
Mfw I'm checking for null
?:)
Holy shit
It was called Elvis back when it was a smiley
Kotlin user spotted
php too
..but we don't talk about php
php doesn't exist, php can't hurt you
You have absolutely nothing
<?php
well hello there again
?>
to worry about. If PHP existed
we would have sophisticated
<?php
I trust that life has
been treating you well?
?>
methods of detecting it, and
it would pose literally no
<?php
Don't open the door. It's me.

threat to anyone.Oh unfortunately these imaginary pains are those which hurt every day
Nobody's assuming Groovy these days then 😂
I've been working in Jenkins pipeline for a while now.
Why the fuck is Groovy?
Well Grails didn't stick around for long, but Gradle was only available with Groovy for many years before they added Kotlin support.
(run { [email protected]?.apply { this.value === true } } == true) ?: if (([email protected] as? Boolean) != true) false else true
Same
