eyg_interpreter

Gleam implementation of the EYG language. This implementation runs on JavaScript runtimes and works in the browser.

gleam add eyg_interpreter@1

This library defines two execution modes:

• expression - always returns a value
• block - optionally returns a value and the final environment.

If in doubt use the expression module. Block is useful for creating shells (or REPLs, terminals, consoles).

import eyg/interpreter/expression
import eyg/ir/tree as ir

pub fn main() {
  let source = ir.Let("x", ir.Integer(5), ir.Variable("x"))
  let scope = []
  expression.execute(source, scope)
  // => value.Integer(5)
}
