isn't there another better stlib fun instead calling

dropWhile

+

drop

?

if (file.exists())
        file.readLines()
                .dropWhile { !it.startsWith('#') }.drop(1)

you could

readText

, substring on # then split on newline.. not sure if that's any better though 😬

file can be also huge, I guess it's not an option for my case

filter

maybe?

file.readLines().filter { !it.startsWith("#") }

you’re gonna have just the lines that don’t start with #

He need to read from the line starts with ‘#’ and discard all lines before that. Your filter will include those unwanted lines as well

yes, sorry I got the questions wrongly

@elect you shouldn't use

readLines()

for huge files either

ok, thanks

There's

useLines

for large files: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.io/java.io.-file/use-lines.html
