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

[Bruno]

filter maybe?
file.readLines().filter { !it.startsWith("#") }
you’re gonna have just the lines that don’t start with #

[edwardwongtl]

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

[Bruno]

yes, sorry I got the questions wrongly

[david-wg2]

@elect you shouldn't use readLines() for huge files either

[david-wg2]

it's basically the same operation

[david-wg2]

if the file is really that big i think you should just read it normally and make a boolean flag for if you have found your hashtag yet

[elect]

ok, thanks

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

And your current .dropWhile { ... }.drop(1) is fine I'd say.
