1. Prepare

This project developed on macos. But should be easy to port on windows, since it uses ruby.

You need to have ruby 2.6+.

You need to download cpp2ruby first.

cd ..
git clone https://github.com/jackieju/CPP2Ruby.git
cd xcompiler

2. Generate Parser from EBNF

    cd cocoR\
    ./gen_parser [atg file]

In case you change the location of cpp2ruby, you can edit file gen_parser and change the line

    cpp2ruby_dir=../../CPP2Ruby

EBNF(https://tomassetti.me/ebnf/) describes the syntax of source language, written in atg file which will be used by cocoR(http://www.ssw.uni-linz.ac.at/Coco/)

You also put your code in atg to generate code of destination language.

Please see example at https://github.com/jackieju/abap2ruby.

List of atg files(EBNF) for popular langauge: https://github.com/jackieju/xcompiler/tree/master/cocoR/cocor17/samples

3. Modify macro.rb to do preprocessing

4. Modfiy cp.rb to do overriding

5. run

    ruby translate.rb -d [output dir] [source code files]

For example to use xcompiler to translate code, please see https://github.com/jackieju/abap2ruby
