# EYG IR

Work with the intermediate representation of the [EYG](https://eyg.run) language.
The EYG language is "AST first", there is no textual syntax.
Instead the [AST specification](https://github.com/CrowdHailer/eyg-lang/blob/main/ir/README.md) is the public interface of the language.

This means the language does not need a lexer parser.
Writing interpreters or compilers is therefor much simpler.

This library defines:
- A Gleam data structure for working with EYG programs.
- Create immutable references for EYG programs using the [dag-json](https://ipld.io/docs/codecs/known/dag-json/) codec.

gleam add eyg_ir@1
```
```gleam
import eyg/ir/dag_json

pub fn main() {
  let bytes = simplifile.read_bits("my_program.eyg.json")
  let source = dag_json.from_block(bytes)
}
```
