Anyone good with regex? What is this actually splitting my string on?

myCowboy.split("\\$")

If it was a regex pattern, it would match a dollar sign

in Kotlin, String.split(String) doesn't split on a pattern, it splits on a literal match

Yeah, I was just about to remember that

this is different (but saner) than Java's String.split

sorry. it is actually

.split(regex = "\\$".toRegex())

you could also write

"""\$""".toRegex()

backslashes don't need to be escaped in multiline quotes

i recommend using online regex editors btw. they're a tremendous help and visualize what's happening in the matcher system

Yeah. I tried but what getting different results depending if I had an extra \ and so I was just confused if the online tool was getting escaped or not

However, In this particular case, you can just do

myCowboy.split('$')

or

myCowboy.split("$")

. Normally, you would have to quote the

$

in strings if you want a literal

$

because of Kotlin's templating. However, a

$

at the end of a String literal does not require quoting.

$

before anything that doesn't look like interpolation will work without escaping

yup

"$0"

,

"$$"

,

"$[]"

, etc.
