Out of curiosity, I took a look to the Grips source code and used Logtalk
ability to compile Prolog module code to learn about possible portability
issues. The code uses some SWI-Prolog features, which makes porting difficult.
It uses a back quote as an operator, which is problematic. As an example, the
code only compiles with SWI-Prolog V7 using the --traditional command-line
flag. It declares operators in the pseudo-module "user" that SWI-Prolog makes
available through a kind of inheritance mechanism to the module that contains
the op/3 directives. A bigger issue is the use of module_transparent/1
directives, which cannot be simply replaced by more meta_predicate/1
directives. Thus, porting is not trivial.
Cheers,
Paulo
