The Liom Programming Language

Liom is a toy programming language I created as a learning experience. For more information on the syntax, see here.

Features

Parser

• Variable definition
• Literal expression
  • Integer
  • Character
  • String
  • Byte
  • Float
  • Boolean
• Variable reference
• Binary expression
• Unary expression

Interpreter

• Variable definition
• Literal expression
  • Integer
  • Character
  • String

Installation

Requirements

• cargo with a recent nightly toolchain
• (Optional) cargo-fuzz if you want to run the fuzzer

To build the executable :

cargo build --release

The executable will be in target/release/liom_cli

Usage

To run the REPL :

target/release/liom_cli

Contributing

I'm open to contributions, don't hesitate to open issues and submit PR. I try to keep the dependency graph small.

To format the code :

./ci/fmt.sh

To lint and test the code :

./ci/check.sh

To fuzz the code for 30min :

./ci/fuzz.sh
