O.k. I wrote minimum version of prolog parser. ``` $ cat input.pl mother_child(trude, sally). $ cat prolog.ctags --langdef=Prolog --map-Prolog=.pl --kinddef-Prolog=p,predicate,predicates --regex-Prolog=/^([a-zA-Z_]+)\([^.]+\)./\1/p/ $ ./ctags --options=./prolog.ctags --languages=Prolog -o - input.pl mother_child input.pl...

Let's extend the input a bit. ``` parent_child(X, Y) :- father_child(X, Y). parent_child(X, Y) :- mother_child(X, Y). ``` The first question is `parent_child` should be tagged twice or once? I...

``` $ cat input.pl /* input.pl */ mother_child(trude, sally). father_child(tom, sally). father_child(tom, erica). father_child(mike, tom). sibling(X, Y) :- parent_child(Z, X), parent_child(Z, Y). parent_child(X, Y) :- father_child(X, Y). parent_child(X, Y) :-...

I guess arity field and signature field should be filled.

Feel free to reopen this.

Thank you for the information. However, using the code in ctags is limited: ```C /* * ptags - creates entries in a tags file for Prolog predicates * * Usage:...

BTW, will you help me test the parser? We already have a prototype. https://github.com/universal-ctags/ctags/issues/2628#issuecomment-679816894

@dseddah, could you try #4249? I have not used the ptags code directly. ``` $ cat input.pl :- module(mymod, [a/0, a/1, a/2]). a. a(X) :- X is 1. a(X, Y)...
