How to resolve the algorithm Program name step by step in the Prolog programming language

Table of Contents

Problem Statement

The task is to programmatically obtain the name used to invoke the program. (For example determine whether the user ran "python hello.py", or "python hellocaller.py", a program importing the code from "hello.py".) Sometimes a multiline shebang is necessary in order to provide the script name to a language's internal ARGV. See also Command-line arguments Examples from GitHub.

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Program name step by step in the Prolog programming language

Source code in the prolog programming language

% SWI-Prolog version 8.0.0 for i686-linux.
% This will find itself, and return the knowledge base it is in.
file_name(F) :- true
   , M = user            % M is the module    .
   , P = file_name(_)    % P is the predicate .
   , source_file(M:P, F) % F is the file      .
   , \+ predicate_property(M:P, imported_from(_))
   .


:- multifile(this_is_one_of_my_files). this_is_one_of_my_files.
