I get string:
name: tom, weight: 50, age: 21

How I can get value name, weight, age?

[andylamax]

"name: tom, weight: 50, age: 21".split(",").map {
    it.split(":").first()
}.joinToString(",")

Thank you but I maybe wrote incomprehensibly. I want to get value of name, weight, age.

[andylamax]

"name: tom, weight: 50, age: 21".split(",").map {
    it.split(":")[1]
}.joinToString(",")

[Ink]

Thanks a lot!

[Ink]

One more question. How I can assign those values to variables?

[gildor]

val (name, weight, age) = "name: tom, weight: 50, age: 21".split(",").map {
    it.split(":")[1]
}

[gildor]

or just do:
val name = result[0]
val weight = result[1]

[Ink]

what is the result?

[andylamax]

val result = "name: tom, weight: 50, age: 21".split(",").map {
    it.split(":")[1]
}

[Ink]

Thanks!

I prefer regexes for these kinds of things, try to learn up on those! 🙂👍

[gildor]

Why use regex if it can be easily parsed manually (and as a result you can implement a lot better error parsing than just generic success/fail as in case of regex)

Some people, when confronted with a problem, think “I know, I’ll use regular expressions.” Now they have two problems.

[Michael de Kaste]

didn't expect so much regex hate 😛

@Sam That’s one of Jamie’s best quotes, and it is still true!

[gildor]

It's not a matter of hate, regex have their own usages, but it doesn't mean that they are the best solution in all situations when you need parsing
