With the introduction of PrologScript (see section 2.11.1.1), using shell scripts as explained in this section has become redundant for most applications.
Especially on Unix systems and not-too-large applications, writing a
shell script that simply loads your application and calls the entry
point is often a good choice. A skeleton for the script is given below,
followed by the Prolog code to obtain the program arguments. See library library(main)
and argv_options/3
for details.
#!/bin/sh base=<absolute-path-to-source> SWIPL=swipl exec $SWIPL "$base/load.pl" -- "$@"
:- use_module(library(main)).
:- initialization(main,main).
main(Argv) :-
argv_options(Argv, Positional, Options),
go(Positional, Options).
go(Positional, Options) :-
...
On Windows systems, similar behaviour can be achieved by creating a
shortcut to Prolog, passing the proper options or writing a .bat
file.
