A toy functional language compiler written in Python

Project description

# LnaC

### A toy functional language compiler written in Python.


LnaC is a toy functional language compiler written in Python 3 that supports limited program generation.

For some sample programs, see the [demos directory](demos).

## Quickstart

To install LnaC:
pip3 install lnac

To create, compile, and run an example program:
$ nano return0.lna
$ less return0.lna

main : int
main =
=> 0

$ lnac return0.lna
$ ./return0 && $?

## Implementation

### Lexer
The LnaC lexer is primarily implemented in [``](lnac/ Additionally, [``](lnac/ contains definitions of the token classes used in the lexer and instances of recognized keyword and symbol tokens.

### Parser
The LnaC parser is implemented in [`parser/`](lnac/parser/) and creates an abstract syntax tree of nodes defined in [`tree/`](lnac/tree/

### Assembly
LnaC writes out an intermediary assembly file that gcc then generates an executable from. This assembly file is written following the AT&T assembly syntax and is deleted following a successful compilation.
