gleam add glint
Usage
You can import glint
as a dependency and use it as follows:
import gleam/io
import gleam/map
import gleam/erlang.{start_arguments}
import glint.{CommandInput}
import glint/flag
pub fn main() {
let hello_world = fn(input: CommandInput) {
assert Ok(flag.BoolFlag(caps)) = map.get(input.flags, "caps")
case caps {
True -> io.println("HELLO, WORLD!")
False -> io.println("Hello, World!")
}
}
glint.new()
|> glint.add_command([], hello_world, [flag.string("caps", False)])
|> glint.run(start_arguments())
}
Run it with either of:
gleam run
which will printHello, World!
gleam run -- --caps=true
which will printHELLO, WORLD!
