Simple Scripting Language (SSL)

One of the project I.ve wanted to undertake for a while now is writing a simple programing language.

Requirements

• Variables/Literals let a = 1
• Integers, Booloean, Strings
• Block Based
• if/else: if else
• comparison operators: == != > >= < <=
• boolean operators: || && !
• mathematical operators: + - / * ** %
• print: print

Example

let foo = "foo"

let bar = if foo == "foo" {
  true
} else {
  false
}

print bar

Abstract Syntax Tree

body [
  assignment: {
    variable: "foo",
    value: literal { "foo" },
  },
  assignment {
    variable: "bar",
    value: if_statement {
      condition: bin_op {
        op: "equals",
        a: variable { "foo" },
        b: literal { "foo" },
      },
      branch: [
        literal { true },
      ],
      else: [
        literal { false },
      ],
    },
  },
  print {
    args: variable { "var" },
  },
]
