Preamble % % This license establishes the terms under which a given free software % Package may be copied, modified, distributed, and/or % redistributed. The intent is that the Copyright Holder maintains some % artistic control over the development of that Package while still % keeping the Package available as open source and free software. % % You are always permitted to make arrangements wholly outside of this % license directly with the Copyright Holder of a given Package. If the % terms of this license do not permit the full use that you propose to % make of the Package, you should contact the Copyright Holder and seek % a different licensing arrangement. Definitions % % "Copyright Holder" means the individual(s) or organization(s) named in % the copyright notice for the entire Package. % % "Contributor" means any party that has contributed code or other % material to the Package, in accordance with the Copyright Holder's % procedures. % % "You" and "your" means any person who would like to copy, distribute, % or modify the Package. % % "Package" means the collection of files distributed by the Copyright % Holder, and derivatives of that collection and/or of those files. A % given Package may consist of either the Standard Version, or a % Modified Version. % % "Distribute" means providing a copy of the Package or making it % accessible to anyone else, or in the case of a company or % organization, to others outside of your company or organization. % % "Distributor Fee" means any fee that you charge for Distributing this % Package or providing support for this Package to another party. It % does not mean licensing fees. % % "Standard Version" refers to the Package if it has not been modified, % or has been modified only in ways explicitly requested by the % Copyright Holder. % % "Modified Version" means the Package, if it has been changed, and such % changes were not explicitly requested by the Copyright Holder. % % "Original License" means this Artistic License as Distributed with the % Standard Version of the Package, in its current version or as it may % be modified by The Perl Foundation in the future. % % "Source" form means the source code, documentation source, and % configuration files for the Package. % % "Compiled" form means the compiled bytecode, object code, binary, or % any other form resulting from mechanical transformation or translation % of the Source form. % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % % Permission for Use and Modification Without Distribution % % (1) You are permitted to use the Standard Version and create and use % Modified Versions for any purpose without restriction, provided that % you do not Distribute the Modified Version. % % Permissions for Redistribution of the Standard Version % % (2) You may Distribute verbatim copies of the Source form of the % Standard Version of this Package in any medium without restriction, % either gratis or for a Distributor Fee, provided that you duplicate % all of the original copyright notices and associated disclaimers. At % your discretion, such verbatim copies may or may not include a % Compiled form of the Package. % % (3) You may apply any bug fixes, portability changes, and other % modifications made available from the Copyright Holder. The resulting % Package will still be considered the Standard Version, and as such % will be subject to the Original License. % % Distribution of Modified Versions of the Package as Source % % (4) You may Distribute your Modified Version as Source (either gratis % or for a Distributor Fee, and with or without a Compiled form of the % Modified Version) provided that you clearly document how it differs % from the Standard Version, including, but not limited to, documenting % any non-standard features, executables, or modules, and provided that % you do at least ONE of the following: % % (a) make the Modified Version available to the Copyright Holder of the % Standard Version, under the Original License, so that the Copyright % Holder may include your modifications in the Standard Version. (b) % ensure that installation of your Modified Version does not prevent the % user installing or running the Standard Version. In addition, the % modified Version must bear a name that is different from the name of % the Standard Version. (c) allow anyone who receives a copy of the % Modified Version to make the Source form of the Modified Version % available to others under (i) the Original License or (ii) a license % that permits the licensee to freely copy, modify and redistribute the % Modified Version using the same licensing terms that apply to the copy % that the licensee received, and requires that the Source form of the % Modified Version, and of any works derived from it, be made freely % available in that license fees are prohibited but Distributor Fees are % allowed. % % Distribution of Compiled Forms of the Standard Version or % Modified Versions without the Source % % (5) You may Distribute Compiled forms of the Standard Version without % the Source, provided that you include complete instructions on how to % get the Source of the Standard Version. Such instructions must be % valid at the time of your distribution. If these instructions, at any % time while you are carrying out such distribution, become invalid, you % must provide new instructions on demand or cease further % distribution. If you provide valid instructions or cease distribution % within thirty days after you become aware that the instructions are % invalid, then you do not forfeit any of your rights under this % license. % % (6) You may Distribute a Modified Version in Compiled form without the % Source, provided that you comply with Section 4 with respect to the % Source of the Modified Version. % % Aggregating or Linking the Package % % (7) You may aggregate the Package (either the Standard Version or % Modified Version) with other packages and Distribute the resulting % aggregation provided that you do not charge a licensing fee for the % Package. Distributor Fees are permitted, and licensing fees for other % components in the aggregation are permitted. The terms of this license % apply to the use and Distribution of the Standard or Modified Versions % as included in the aggregation. % % (8) You are permitted to link Modified and Standard Versions with % other works, to embed the Package in a larger work of your own, or to % build stand-alone binary or bytecode versions of applications that % include the Package, and Distribute the result without restriction, % provided the result does not expose a direct interface to the Package. % % Items That are Not Considered Part of a Modified Version % % (9) Works (including, but not limited to, modules and scripts) that % merely extend or make use of the Package, do not, by themselves, cause % the Package to be a Modified Version. In addition, such works are not % considered parts of the Package itself, and are not subject to the % terms of this license. % % General Provisions % % (10) Any use, modification, and distribution of the Standard or % Modified Versions is governed by this Artistic License. By using, % modifying or distributing the Package, you accept this license. Do not % use, modify, or distribute the Package, if you do not accept this % license. % % (11) If your Modified Version has been derived from a Modified Version % made by someone other than you, you are nevertheless required to % ensure that your Modified Version complies with the requirements of % this license. % % (12) This license does not grant you the right to use any trademark, % service mark, tradename, or logo of the Copyright Holder. % % (13) This license includes the non-exclusive, worldwide, % free-of-charge patent license to make, have made, use, offer to sell, % sell, import and otherwise transfer the Package with respect to any % patent claims licensable by the Copyright Holder that are necessarily % infringed by the Package. If you institute patent litigation % (including a cross-claim or counterclaim) against any party alleging % that the Package constitutes direct or contributory patent % infringement, then this Artistic License to you shall terminate on the % date that such litigation is filed. % % (14) Disclaimer of Warranty: THE PACKAGE IS PROVIDED BY THE COPYRIGHT % HOLDER AND CONTRIBUTORS "AS IS' AND WITHOUT ANY EXPRESS OR IMPLIED % WARRANTIES. THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A % PARTICULAR PURPOSE, OR NON-INFRINGEMENT ARE DISCLAIMED TO THE EXTENT % PERMITTED BY YOUR LOCAL LAW. UNLESS REQUIRED BY LAW, NO COPYRIGHT % HOLDER OR CONTRIBUTOR WILL BE LIABLE FOR ANY DIRECT, INDIRECT, % INCIDENTAL, OR CONSEQUENTIAL DAMAGES ARISING IN ANY WAY OUT OF THE USE % OF THE PACKAGE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE. % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% :- module(intervals, [intervals_merge/3, intervals_disjoin/3, intervals_disjoin/4, intervals_partition/2, intervals_encode/2]). :- style_check(all). :- yap_flag(unknown,error). :- use_module(library(lists), [member/2, reverse/2, select/3]). %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % intervals_merge(+Interval1,+Interval2,-ResultingInterval) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% intervals_merge(all,X,X). intervals_merge(none,_,none). intervals_merge(above(X),Other,Result) :- number(X), intervals_merge_above(Other,X,Result). intervals_merge(below(X),Other,Result) :- number(X), intervals_merge_below(Other,X,Result). intervals_merge(interval(X1,X2),Other,Result) :- number(X1), number(X2), intervals_merge_interval(Other,X1,X2,Result). intervals_merge_above(all,X,above(X)). intervals_merge_above(none,_,none). intervals_merge_above(above(Y),X,above(Z)) :- number(Y), Z is max(X,Y). intervals_merge_above(below(Y),X,Result) :- number(Y), ( X= Result=interval(X,Y); Result=none ). intervals_merge_above(interval(Y1,Y2),X,Result):- number(Y1), number(Y2), ( X= Result=interval(Y1,Y2); ( X= Result=interval(X,Y2); Result=none ) ). intervals_merge_below(all,X,below(X)). intervals_merge_below(none,_,none). intervals_merge_below(above(Y),X,Result) :- number(Y), ( Y= Result=interval(Y,X); Result=none ). intervals_merge_below(below(Y),X,below(Z)) :- number(Y), Z is min(X,Y). intervals_merge_below(interval(Y1,Y2),X,Result) :- number(Y1), number(Y2), ( X>=Y2 -> Result=interval(Y1,Y2); ( X>=Y1 -> Result=interval(Y1,X); Result=none ) ). intervals_merge_interval(all,X1,X2,interval(X1,X2)). intervals_merge_interval(none,_,_,none). intervals_merge_interval(above(X),Y1,Y2,Result) :- number(X), intervals_merge_above(interval(Y1,Y2),X,Result). intervals_merge_interval(below(X),Y1,Y2,Result) :- number(X), intervals_merge_below(interval(Y1,Y2),X,Result). intervals_merge_interval(interval(X1,X2),Y1,Y2,Result) :- number(X1), number(X2), ( X1 intervals_merge_interval_intern(X1,X2,Y1,Y2,Result); intervals_merge_interval_intern(Y1,Y2,X1,X2,Result) ). intervals_merge_interval_intern(_X1,X2,Y1,Y2,Result) :- ( Y1= ( Y2= Result=interval(Y1,Y2); Result=interval(Y1,X2) ); Result=none ). %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% select_all([],List,List). select_all([H|T],List,Remainder) :- once(select(H,List,TMP)), select_all(T,TMP,Remainder). %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% intervals_disjoin(X,P,In,Out) :- disjoin_intern(X,P,In), select_all(In,P,Out). intervals_disjoin(X,P,In) :- disjoin_intern(X,P,In). disjoin_intern(below(X),P,In) :- findall((interval(A,B),Tail),(member((interval(A,B),Tail),P),B= In=[(below(Y),Tail)|Tmp]; In=Tmp ). disjoin_intern(above(X),P,In) :- findall((interval(A,B),Tail),(member((interval(A,B),Tail),P),A>=X),Tmp), ( (member((above(Y),Tail),P),Y>=X) -> In=[(above(Y),Tail)|Tmp]; In=Tmp ). disjoin_intern(interval(X,Y),P,In) :- findall((interval(A,B),Tail),(member((interval(A,B),Tail),P),A>=X,B= X2 is 2*X; X2 is -1000 ), intervals_encode(interval(X2,X),Atom). intervals_encode(above(X),Atom) :- ( X > 1000 -> X2 is 2*X; X2 is 1000 ), intervals_encode(interval(X,X2),Atom). intervals_encode(interval(Low,High),Atom) :- once(my_number_atom(Low,LowA)), once(my_number_atom(High,HighA)), atomic_concat([l,LowA,h,HighA],Atom). my_number_atom(Number,Atom) :- % make float NumberF is Number+0.0, number_codes(NumberF,XC), reverse(XC,A), remove_prefix_zeros(A,B), remove_prefix_dot(B,C), fix_special_cases(C,D), reverse(D,DC), replace_special_characters(DC,DC_Final), atom_codes(Atom,DC_Final). remove_prefix_zeros([],[]). remove_prefix_zeros([X|T],Result) :- ( X==48 % 48 = '0' -> remove_prefix_zeros(T,Result); Result=[X|T] ). remove_prefix_dot([],[]). remove_prefix_dot([X|T],Result) :- ( X==46 % 46 = '.' -> Result=T; Result=[X|T] ). fix_special_cases([],[48]). fix_special_cases([H|T],Result) :- ( [H|T] == [48,45] % ='0-' -> Result=[48]; Result=[H|T] ). replace_special_characters([],[]). replace_special_characters([H|T],[H2|T2]) :- ( H==45 % '-' -> H2=109; % 'm' ( H==46 -> H2=100; % 'd' H2=H ) ), replace_special_characters(T,T2).
