> I did not look at your code in detail but from the description it might be related to code Jan W. has created for building [SWI-Prolog](https://www.swi-prolog.org/pldoc/doc_for?object=manual), e.g. library/build

It seems that Jan code is to manage build systems like CMake or Make.  
Ce pack I have written is to help generate a ninja build file, much like what CMake does when generating a ninja build file or makefile.

By the way, I’ve recently stumbled across one of your comment [here](https://swi-prolog.discourse.group/t/wiki-discussion-dcg-and-phrase-3/735/2) about a dcg to parse postscript.  
However, you only posted test case for the grammar and not the grammar itself.  
Would it be possible to share the grammar ?  
I would be very interested in a DCG that can parse postscript/pdf files.
