The goals of this project are:

- Fully homegrown

- No dependencies

- Start with lexer and parser

  - No runtime or compiler (yet)

- Static typings

  - No runtime or build-time type checking (yet)

## Syntax

```shell

infer Test = 0 + 1 + 2;

infer Other = 0;

```

Outputs the following AST:

```json

{

  "type": "Program",

  "body": [

    {

      "type": "InferStatement",

      "identifier": {

        "type": "Identifier",

        "val": "Test"

      },

      "value": {

        "type": "AddStatement",

        "left": {

          "type": "Number",

          "val": "0"

        },

        "right": {

          "type": "AddStatement",

          "left": {

            "type": "Number",

            "val": "1"

          },

          "right": {

            "type": "Number",

            "val": "2"

          }

        }

      }

    },

    {

      "type": "InferStatement",

      "identifier": {

        "type": "Identifier",

        "val": "Test"

      },

      "value": {

        "type": "Number",

        "val": "0"

      }

    }

  ]

}

> This project is currently held together by ducktape and string. I've never built a lexer, parser, or compiler before.

>

> I'm learning as I go. I'm sure there are many things I'm doing wrong. I'm open to feedback.

>

> I'm also intentionally taking the slow route at times and not referencing existing implementation or documentation at this time.
