This is an experiment to examine what would be the optimal syntax for a cross-platform build system. Dependencies: Python3 and Python-Ply Running: Builder requires that you have a source directory and a build directory and that these two are different. In your source root must exist a file called 'builder.txt'. To generate the build system run this command: builder.py You can omit either of the two directories, and Builder will substitute the current directory and autodetect what you mean. This mean that you can do things like this: cd source_root; mkdir build; cd build; builder .. cd source_root; mkdir build; builder build For questions contact jpakkane@gmail.com.
