# LEXY: tiny, made up lisp
This is the source code repository of `lexy`, a tiny implementation of a
Lisp-like language. It contains the interpreter, the REPL, the standard library
as well the documentation.
The original implementation has been made upon the guidance of the [Build Your
Own Lisp](http://www.buildyourownlisp.com/) book.

## Significant improvements
1. code modularization
1. new math-related builtin functions such as `pow`, `sqrt` and `mod`
1. constant and dynamic variables (`letc` and `let` respectively)
## Getting started
### Build requirements
`gcc` and `make` are required to compile. Additionally, the `editline` headers
are used by lexy. In Debian-based systems, the following command should install
all the necessary packages:
```sh
$ sudo apt-get install -y build-essential libedit-dev
```
### Compiling from source
Just `make`. The binary will be available at the project's root directory.
### Installing & Uninstalling
To install, just use:
```sh
sudo make install
```
To uninstall:
```sh
sudo make uninstall
```
### Running in Docker
If you'd prefer to use Docker, you can build the image locally and run
interactively.
```sh
$ docker build -t lexy .
$ docker run -it lexy
```
## Roadmap
Expected improvements until the next release (`v0.1.0`):
1. [ ] Proper modules support
1. [ ] Hash table powered symbol lookup
1. [ ] Hashmap built-in type
1. [ ] Hashmap operations
1. [ ] Expand standard library
1. [x] Command-line arguments (help, eval string etc)
1. [ ] Receive arguments from the shell
1. [ ] REPL improvements (colors, keywords)
1. [ ] Tests
