xre-engine - Expression Evaluation Engine

This is a learning project for me to better understand interpreted programming languages design

// finding prime numbers in range 0, 20

i=0;{i=i+1}<=20 loop{f=0;j=1;j<20 loop{!{i%j}do{f=f+1};j=j+1};f==2 do print i}

output:
2
3
5
7
11

Installation

install xre via Git using the install script:

$ git clone https://github.com/pauldcs/xre-engine
$ ./xre-engine/install.sh
 ...
$ xre -h

Developement

The makefile in the root directory creates a docker container that shares the sources (engine) between your host machine and the container. This makes it possible and easy to develop on any host while always compiling on a standard linux distro.

The container is created by running:

$ make
# Ctrl-D to stop the container

Once the container is created, you get a bash shell to it by opening a new terminal and running:

$ make shell
root @xre-dev $ cd engine
root @xre-dev $ make
root @xre-dev $ ./xre -v
