# Loki

Loki is an experimental programming language that I am building both to learn more about compilers and test ideas about language design.

## Disclaimer

Since I don't find rust to be a productive language anymore I am now trying to implement a similar langauge in GO which I will open source soon.

## Installation

```bash

git clone https://github.com/amirrezaask/loki.git

cd loki

cargo install --path .

# if you have added cargo bins inside your path you can use loki command.

```

## How It works

Loki compiler consists of multiple stages of compilation:

- Lexer: produce a stream of tokens for each input file.

- Parser: produces an IR structure for each file.

- Type checker and inference: type inference and checking of the IR happens here.

- Bytecode: lowering language features into simpler constructs happen here.

- Backend code generation: this will produce code that gets compiled or assembled using a third party toolchain.

  * C: Done.

## Todos

- Loki main should wrap user main function so we handle return int and stuff.

- Default values for structs

- Defer: *each function that have a defer usage, will have a label at the end (with a guard) so when user does return we first jump to defer run the instructions and then we come back and return.

- Unions

- Type table in output binary + access through #type() directive that will result in the type of the expression.

- Definitions of #load that will make exported symbols accessible from a namespace.

- LLVM

- If and while and for to not require parens in parser. ( Parser has ambiguity due to expr { means initialize , so we should change initialize syntax if we want this.)

- Generics
