This is a SWI-Prolog (http://www.swi-prolog.org/) pack.
It can be installed with pack_install/1
$ swipl ?- pack_install(sldnfdraw).
$ cd <pack>/sldnfdraw/prolog/examples $ swipl ?- [member]. ?- draw_goal("tree.tex").
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,eepic} \usepackage{ecltree} \begin{document} \input{tree} \end{document}
and you should compile it with
latex file.tex dvipdf file.dvi
If the graph is too condensed, you can change the spacing with
\setlength{\GapDepth}{30pt} \setlength{\EdgeLabelSep}{15pt} \setlength{\GapWidth}{30pt}
inserted befeore `\begin{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
epic
and ecltree
