SLDNF Draw is a Prolog program that draws SLDNF Trees in LaTeX

See:

Marco Gavanelli SLDNF-Draw: Visualization of Prolog operational semantics in LaTeX, Intelligenza Artificiale, vol. 11, no. 1, pp. 81-92, 2017. DOI: 10.3233/IA-170108. http://content.iospress.com/articles/intelligenza-artificiale/ia108

Installation

This is a SWI-Prolog (http://www.swi-prolog.org/) pack.

It can be installed with pack_install/1

$ swipl
?- pack_install(sldnfdraw).

Example of use

$ cd <pack>/sldnfdraw/prolog/examples
$ swipl
?- [member].
?- draw_goal("tree.tex").

Usage

Prepare an input file that first loads the module sldnfdraw

:- use_module(library(sldnfdraw)).

Then initialize the library with

:- sldnf.

You can now write the program you want to query by including it within the directives :-begin_program. and :-end_program. as in

:-begin_program.

member(X ,[X|_T]).
member(X ,[_H|T]):-
  member(X,T).

:-end_program.

You can now write the query by including it within the directives :-begin_query. and :-end_query. as in

:-begin_query.

member(X,[1,2]), \+ member(X,[1,3]).

:-end_query.

You can now build the SLDNF tree with the predicate draw_goal/1. If you call it with a variable as in

?- draw_goal(T).

it will return in T a string with the LaTex code for drawing the tree, that you can then include in a LaTeX document.

If you call draw_goal/1 with a string as in

?- draw_goal("tree.tex").

it will write the LaTeX code in file tree.tex in the current folder. You can then include it in a LaTeX document. The minimal LaTeX file you could use is

\documentclass{article}
\usepackage{epic}
\usepackage{ecltree}
\begin{document}
\input{tree}
\end{document}

If you are using your example in SWISH and want the output to be shown in SVG add the following code after laoding the library

:- if(current_predicate(use_rendering/1)).
:- use_rendering(sldnf).
:- endif.

and you need the following programs on the server

In Ubuntu you would need the packages

texlive
texlive-extra-utils
texlive-humanities
texlive-pictures
pdf2svg
