Erupt

Erupt is my attempt at building a compiler in C. This project is for learning purpose only and should not be used in production.

Example

A simple hello world program may look like this:

use io;

fun main
{
    io::writeln("Hello world");
}

Installation

Installing Erupt requires some dependencies:

Dependencies

git
LLVM >= 3.6 installed and llvm-config in your $PATH
a C and C++ compiler (eg. gcc, clang)
GNU make

Building

$ git clone https://github.com/soudy/Erupt
$ cd Erupt
$ make

Or if you wish to use a non-default C compiler:

$ CC=compiler make

(where compiler is the compiler of choice).

Erupt has been tested and proven to work with gcc 5.2.0 and clang 3.6.2 on x86_64 GNU/Linux, but most other C compilers with C99 support should work.

This will create the binary bin/erupt. If you wish to install erupt into your path, run make install with superuser privileges.

Run

$ erupt [options] file

Options

-o, --output
       set output name (default: main)
-v, --version
       show version
-V, --verbose
       verbose mode
-t, --tokens
       show generated token stream
-n, --nodes
       show nodes of the generated AST
-h, --help
       show this
