glance

A Gleam source code parser, in Gleam!

Glance attempts to be permissive with regards to what it will parse and so it is able to parse some code that the Gleam compiler will reject as invalid.

Usage

Add the package to your Gleam project:

gleam add glance

Then get parsing!

import glance
import gleam/io

const code = "
 pub type Cardinal {
   North
   East
   South
   West
 }
"

pub fn main() {
 let assert Ok(parsed) = glance.module(code)
 io.debug(parsed.custom_types)
}

This program print this to the console:

[
 Definition(
   [],
   CustomType(
     name: "Cardinal",
     publicity: Public,
     parameters: [],
     variants: [
       Variant("North", []),
       Variant("East", []),
       Variant("South", []),
       Variant("West", []),
     ],
   ),
 ),
]
