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

"\\" is escaping the `\` in the Kotlin string

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

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

sorry. it is actually
```.split(regex = "\\$".toRegex())```


okay. so its splitting on a dollar sign. interesting. thank you

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

should you use that, maybe not. but it works
