What did you do?

1. Make a file and name it json.v

import json

struct User {
    name          string
    age           int
}

fn main() {
    s := '[{"name":"Frodo", "age":25}, {"name":"Bobby", "age":10}]'
    users := json.decode([]User, s) or { // json.decode untuk decode
        eprintln('Failed to parse json')
        return
    }
    for user in users {
        println('$user.name: $user.age')
    }
    //~ println(json.encode(users)) // untuk encode
}

1. On terminal, I run v run json.v

What did you expect to see?

Frodo: 25
Bobby: 10

What did you see instead?

$ v run json.v

@egodasa why you put v under root directory ?

NOT RECOMMENEDED

~$ sudo su
~$ v run json.v 

alternative, put v somewhere in your home directory. then create a symlink to/usr/bin/

[egodasa]

@bokunodev V installed via AUR on manjaro. Looks like the executable are placed under root directory by AUR scripts. Looks like this is not a bug. I will close the issue now.
