=============
|
||||
|
||||
|
||||
2.17.1 - June 7, 2004
|
||||
|
||||
Added custom handling of specification of predicate exceptions in info/2
|
||||
documenting directives when writing XML documenting files (declared as
|
||||
"exceptions is [Cond1-Term1, Cond2-Term2, ...]"; each pair (Condi, Termi)
|
||||
represents an error condition and its respective exception).
|
||||
|
||||
Changed debugger command "e" to print exception terms instead of exiting
|
||||
Logtalk session.
|
||||
|
||||
Corrected a compilation error with B-Prolog due to operator priorities.
|
||||
|
||||
Corrected a possible problem with the redefinition of loaded entities that
|
||||
define (possibly at runtime) dynamic predicates. All clauses for an entity
|
||||
dynamic predicates are retracted before loading the new entity definition.
|
||||
|
||||
Corrected a potential bug when pretty printing terms with variables in the
|
||||
debugger and in the created XML documenting files.
|
||||
|
||||
Added four more DCGs examples ("walker movements", "iterative shell command
|
||||
parsing", "bill of materials", and "command language").
|
||||
|
||||
New "puzzles" and "metainterpreters" examples.
|
||||
|
||||
Added a mode bundle for the SubEthaEdit 2.x (MacOS X) text editor providing
|
||||
syntax coloring for editing Logtalk source files. Optimized some of the
|
||||
regular expressions in the syntax coloring files for the Kate/Kwrite and Vim
|
||||
text editors.
|
||||
|
||||
Removed predicate nth/3 from library entities listp, list, and difflist.
|
||||
Replaced by the predicates nth0/3 and nth1/3. Added new predicates nth1/4
|
||||
and nth0/4.
|
||||
|
||||
Updated the config file for Quintus Prolog to make use of the "files"
|
||||
library.
|
||||
|
||||
Added experimental implementations for some Prolog compilers of the library
|
||||
portable protocol for operating system access (systemp.lgt). See the file
|
||||
library/experimental/NOTES for details.
|
||||
|
||||

/* Mort's Letter from Camp Swampy logical puzzle by Sally Quinn
|
||||
|
||||
Dear Mom and Dad,
|
||||
|
||||
I am having a great time at camp. There are five guys other in my cabin with me and our beds are all lined up in a row. My bed is up against a wall with a window, and when I sleep on my left side I can look out at the moonlight. The boy whose bed is next to mine is from Maine and Sam is next to him. They have become my best friends. We like to go swimming when we have some free time, which isn't often. They keep us pretty busy around here.
|
||||
|
||||
The kids in my cabin come from all over the USA. Mac and the Franklin boy are from neighboring states. John Smith is the only boy from west of the Mississippi River. Fred is from the most southern state and the Thomas kid is from the most northern state. Tim and Sam took a plane to camp, but Mac got to ride in a train.
|
||||
|
||||
When Mr. Miller came to visit his son, he took Sam, Fred, Tim, and me out to dinner with them. When Sam's mom writes to him from North Carolina, she always sends him cookies. He shares them with Mac and Tim whose beds are next to his. Are you going to send me some cookies? I really miss the M & M cookies that you bake every weekend.
|
||||
|
||||
After lights out, I can whisper to the guys whose beds are close. I don't get to talk to the Smith boy much because his bed is the farthest away from mine. We both take horseback riding, and I get to see him then. The girls cabin is next to ours, and sometimes we can hear the girls talking and laughing. Their cabin counselor must not be as strict as ours.
|
||||
|
||||
I am learning how to swim, ride horses, paddle a canoe, and shoot a bow and arrow. Maybe when I get home, I can show you all that I have learned here at camp.
|
||||
|
||||
Well, it's bed time now, so I have to go. I love you and send cookies.
|
||||
|
||||
Love, Mort
|
||||
|
||||
Can you determine who sleeps where in the cabin and where each boy is from?
|
||||
|
||||
Who sleeps where? Include first name, last name, and home state.

/* Horse show logical puzzle by Sally Quinn
|
||||
|
||||
"YouÕll be late for your own funeral." Her motherÕs words kept repeating in AlexÕs head as she approached the fair grounds-late again! It was a curse, no matter how hard she tried, she was always late. This time she had missed the first class of the local horse show. Not really a major crisis, but she had to report the results to the local paper. She couldnÕt let her boss know that she had arrived late. His last words were, "If you are late one more time, youÕre fired!". She needed to figure out another way to write her article accurately for the paper. As Alex entered the show grounds, she overheard bits of conversation which she jotted down.
|
||||
|
||||
"No horse and rider had the same name" ...
|
||||
.."Danny rode his white mare..."...
|
||||
..." the horse named April finished behind the rider named Sue and ahead of the black mare"..
|
||||
..." April rode the Chestnut gelding and finished one place ahead of the bay horse"....
|
||||
.." The Gray horse named Gopher was not first or last place"....
|
||||
..."The horse named Doc was first, and the rider named Doc was third"
|
||||
|
||||
By looking at a program, Alex discovered that the horses and riders names were Doc, April, Sue, Danny, and Gopher. She knew that April and Sue were the only mares. Does Alex have enough information to fool her boss and write the article accurately?

/* Logical puzzle: Who Stole the Jam?
|
||||
|
||||
Someone has stolen the jam! The March Hare said he didn't do it (naturally!) The Mad Hatter proclaimed one of them (the Hare, the Hatter or the Dormouse) stole the jam, but of course it wasn't the Hatter himself. When asked whether the Mad Hatter and March Hare spoke the truth, the Dormouse said that one of the three (including herself) must have stolen the jam.
|
||||
|
||||
By employing the very expensive servieces of Dr. Himmelheber, the famous psychiatrist, we eventually learned that not both the Dormous and the March Hare spoke the truth.
|
||||
|
||||
Assuming, as we do, that fairy-tale characters either always lie or always tell the truth, it remains to discover who really stole the jam.

/* Passing A Note logical puzzle by Sally Quinn
|
||||
|
||||
Jack has a major crush on Jill. During study hall, he finally gathers all of his courage and writes her a note asking her out on Saturday night. The note passes to five students (who all read it) before it gets to Jill. Just as Jill gets the note, Mrs. Wilson the teacher confiscates it. After reading the note, she wants to know all who were involved in the note passing incident. She questions her students, and receives the following responses.
|
||||
|
||||
The girl studying English passed it to Paul who passed it to the girl in green.
|
||||
Josephine passed it to the boy in blue who gave it to Alexis who was reading.
|
||||
The girl in black gave it to Jill.
|
||||
Jack first gave it to Mary who was studying English.
|
||||
The girl in black who was reading got the note from Derrick.
|
||||
|
||||
Mrs. Wilson remembers the following facts from study hall.
|
||||
|
||||
Paul was wearing yellow.
|
||||
Derrick was studying French.
|
||||
The girl in green was studying science.
|
||||
|
||||
From the information given by the students, can you determine what color each culprit was wearing, the subject they were studying and the order that they received the note? Use the chart below to help you.
