nibble
A string parsing library heavily inspired by elm/parser
.
Quick start
import gleam/function
import nibble.{ Parser }
type Point {
Point(x: Int, y: Int)
}
pub fn main () {
let parser =
nibble.succeed(function.curry2)
|> nibble.drop(nibble.grapheme("("))
|> nibble.drop(nibble.spaces())
|> nibble.keep(nibble.int())
|> nibble.drop(nibble.spaces())
|> nibble.drop(nibble.grapheme(","))
|> nibble.drop(nibble.spaces())
|> nibble.keep(nibble.int())
|> nibble.drop(nibble.spaces())
|> nibble.drop(nibble.grapheme(")"))
assert Ok(point) = nibble.run("(1, 2)", parser)
point.x //=> 1
point.y //=> 2
}
