duplicate_term/2. This predicate uses the same technique as

counting the number of solutions of a goal. Note that this
implementation is thread-safe, reentrant and capable of handling
exceptions. Realising these features with a traditional implementation
based on assert/retract or flag/3 is much more complicated.

intended for expert users only because the semantics on backtracking
to a point before creating the link are poorly defined for compound
terms. The principal term is always left untouched, but backtracking
behaviour on arguments is undone if the original assignment was
trailed and left alone otherwise, which implies that the history that
created the term affects the behaviour on backtracking. Please

/** @pred regexp(+ _RegExp_,+ _String_,+ _Opts_,? _SubMatchVars_)
Match regular expression _RegExp_ to input string _String_
according to options _Opts_. The variable _SubMatchVars_ should
be originally unbound or a list of unbound variables all will contain a
sequence of matches, that is, the head of _SubMatchVars_ will
contain the characters in _String_ that matched the leftmost
parenthesized subexpression within _RegExp_, the next head of list
will contain the characters that matched the next parenthesized
subexpression to the right in _RegExp_, and so on.
The options may be:
+ `nocase`: Causes upper-case characters in _String_ to
be treated as lower case during the matching process.
+ `indices`: Changes what is stored in
_SubMatchVars_. Instead of storing the matching characters from
_String_, each variable will contain a term of the form _IO-IF_
giving the indices in _String_ of the first and last characters in
the matching range of characters.
In general there may be more than one way to match a regular expression
to an input string. For example, consider the command
~~~~~
regexp("(a*)b*","aabaaabb", [], [X,Y])
~~~~~
Considering only the rules given so far, _X_ and _Y_ could end up
with the values `"aabb"` and `"aa"`, `"aaab"` and
`"aaa"`, `"ab"` and `"a"`, or any of several other
combinations. To resolve this potential ambiguity `regexp` chooses among
alternatives using the rule `first then longest`. In other words, it
considers the possible matches in order working from left to right
across the input string and the pattern, and it attempts to match longer
pieces of the input string before shorter ones. More specifically, the
following rules apply in decreasing order of priority:
+ If a regular expression could match two different parts of an
input string then it will match the one that begins earliest.
+ If a regular expression contains "|" operators then the leftmost matching sub-expression is chosen.
+ In \*, +, and ? constructs, longer matches are chosen in preference to shorter ones.
+ In sequences of expression components the components are considered from left to right.
In the example above, `"(a\*)b\*"` matches `"aab"`: the
`"(a\*)"` portion of the pattern is matched first and it consumes
the leading `"aa"`; then the `"b\*"` portion of the pattern
consumes the next `"b"`. Or, consider the following example:
~~~~~
regexp("(ab|a)(b*)c", "abc", [], [X,Y,Z])
~~~~~
After this command _X_ will be `"abc"`, _Y_ will be
`"ab"`, and _Z_ will be an empty string. Rule 4 specifies that
`"(ab|a)"` gets first shot at the input string and Rule 2 specifies
that the `"ab"` sub-expression is checked before the `"a"`
sub-expression. Thus the `"b"` has already been claimed before the
`"(b\*)"` component is checked and `(b\*)` must match an empty string.

_Char_ is an ASCII control-character (0..31).
+ `digit`
_Char_ is a digit.
+ `digit( _Weight_)`
_Char_ is a digit with value _Weight_. I.e. `char_type(X, digit(6))` yields X = aaasaá'6'. Useful for parsing numbers.
+ `xdigit( _Weight_)`
_Char_ is a hexa-decimal digit with value _Weight_. I.e. char_type(a, xdigit(X) yields X = '10'. Useful for parsing numbers.
+ `graph`
_Char_ produces a visible mark on a page when printed. Note that the space is not included!
+ `lower`
_Char_ is a lower-case letter.
+ `lower(Upper)`
_Char_ is a lower-case version of _Upper_. Only true if _Char_ is lowercase and _Upper_ uppercase.
+ `to_lower(Upper)`
_Char_ is a lower-case version of Upper. For non-letters, or letter without case, _Char_ and Lower are the same. See also upcase_atom/2 and downcase_atom/2.
+ `upper`
_Char_ is an upper-case letter.
+ `upper(Lower)`
_Char_ is an upper-case version of Lower. Only true if _Char_ is uppercase and Lower lowercase.
+ `to_upper(Lower)`
_Char_ is an upper-case version of Lower. For non-letters, or letter without case, _Char_ and Lower are the same. See also upcase_atom/2 and downcase_atom/2.
+ `punct`
_Char_ is a punctuation character. This is a graph character that is not a letter or digit.
+ `space`
_Char_ is some form of layout character (tab, vertical-tab, newline, etc.).
+ `end_of_file`
_Char_ is -1.
+ `end_of_line`
_Char_ ends a line (ASCII: 10..13).
+ `newline`
_Char_ is a the newline character (10).
+ `period`
_Char_ counts as the end of a sentence (.,!,?).
+ `quote`
_Char_ is a quote-character.
+ `paren(Close)`
_Char_ is an open-parenthesis and Close is the corresponding close-parenthesis.
+ `code_type(? _Code_, ? _Type_)`
As char_type/2, but uses character-codes rather than
one-character atoms. Please note that both predicates are as
flexible as possible. They handle either representation if the
argument is instantiated and only will instantiate with an integer
code or one-character atom depending of the version used. See also
the prolog-flag double_quotes and the built-in predicates
atom_chars/2 and atom_codes/2.

Obtain the properties for the open streams. If the first argument is
unbound, the procedure will backtrack through all open
streams. Otherwise, the first argument must be a stream term (you may
use `current_stream` to obtain a current stream given a file name).
The following properties are recognized:
+ file_name( _P_)
An atom giving the file name for the current stream. The file names are
user_input, user_output, and user_error for the
standard streams.
+ mode( _P_)
The mode used to open the file. It may be one of `append`,
`read`, or `write`.
+ input
The stream is readable.
+ output
The stream is writable.
+ alias( _A_)
ISO-Prolog primitive for stream aliases. <tt>YAP</tt> returns one of the
existing aliases for the stream.
+ position( _P_)
A term describing the position in the stream.
+ end_of_stream( _E_)
Whether the stream is `at` the end of stream, or it has found the
end of stream and is `past`, or whether it has `not` yet
reached the end of stream.
+ eof_action( _A_)
The action to take when trying to read after reaching the end of
stream. The action may be one of `error`, generate an error,
`eof_code`, return character code `-1`, or `reset` the
stream.
+ reposition( _B_)
Whether the stream can be repositioned or not, that is, whether it is
seekable.
+ type( _T_)
Whether the stream is a `text` stream or a `binary` stream.
+ bom(+ _Bool_)
If present and `true`, a BOM (<em>Byte Order Mark</em>) was
detected while opening the file for reading or a BOM was written while
opening the stream. See BOM for details.
+ encoding(+ _Encoding_)
Query the encoding used for text. See Encoding for an
overview of wide character and encoding issues in YAP.
+ representation_errors(+ _Mode_)
Behaviour when writing characters to the stream that cannot be
represented by the encoding. The behaviour is one of `error`
(throw and Input/Output error exception), `prolog` (write `\u...\`
escape code or `xml` (write `\&#...;` XML character entity).
The initial mode is `prolog` for the user streams and
`error` for all other streams. See also Encoding and
`open/4`.
+ current_line_number(- _LineNumber_)
Unify _LineNumber_ with the line number for the current stream.

be represented by the encoding. The behaviour is one of `error`
(throw and Input/Output error exception), `prolog` (write `\u...\`
escape code or `xml` (write `\&#...;` XML character entity).
The initial mode is `prolog` for the user streams and
`error` for all other streams. See also Encoding.
+ `expand_filename(+ _Mode_)`
If _Mode_ is `true` then do filename expansion, then ask Prolog
to do file name expansion before actually trying to opening the file:
this includes processing `~` characters and processing `$`
environment variables at the beginning of the file. Otherwise, just try
to open the file using the given name.
The default behavior is given by the Prolog flag
open_expands_filename.

the interface allows creating and manipulation deterministic finite
automata. A DFA has a set of states, represented as integers
and is initialised with an initial state, a set of transitions from the
first to the last argument emitting the middle argument, and a final
state.
The swedish-drinkers protocol is represented as follows:
~~~~~{.prolog}
A = [X,Y,Z],
dfa( 0, [t(0,0,0),t(0,1,1),t(1,0,0),t(-1,0,0)], [0], C),

This code will enumeratae the valid tuples of three emissions.
+ extensional constraints
Constraints can also be represented as lists of tuples.

would be written as:
~~~~~{.prolog}

in_relation( A, C ),

/** @pred setup_call_cleanup(: _Setup_,: _Goal_, : _CleanUpGoal_)
Calls `(Setup, Goal)`. For each sucessful execution of _Setup_, calling _Goal_, the
cleanup handler _Cleanup_ is guaranteed to be called exactly once.
This will happen after _Goal_ completes, either through failure,
deterministic success, commit, or an exception. _Setup_ will
contain the goals that need to be protected from asynchronous interrupts
such as the ones received from `call_with_time_limit/2` or thread_signal/2. In
most uses, _Setup_ will perform temporary side-effects required by
_Goal_ that are finally undone by _Cleanup_.
Success or failure of _Cleanup_ is ignored and choice-points it
created are destroyed (as once/1). If _Cleanup_ throws an exception,
this is executed as normal.
Typically, this predicate is used to cleanup permanent data storage
required to execute _Goal_, close file-descriptors, etc. The example
below provides a non-deterministic search for a term in a file, closing
the stream as needed.
~~~~~{.prolog}
term_in_file(Term, File) :-
setup_call_cleanup(open(File, read, In),
term_in_stream(Term, In),
close(In) ).
term_in_stream(Term, In) :-
repeat,
read(In, T),
( T == end_of_file
-> !, fail
; T = Term
).
~~~~~
Note that it is impossible to implement this predicate in Prolog other than
by reading all terms into a list, close the file and call member/2.
Without setup_call_cleanup/3 there is no way to gain control if the
choice-point left by `repeat` is removed by a cut or an exception.
`setup_call_cleanup/2` can also be used to test determinism of a goal:
~~~~~
?- setup_call_cleanup(true,(X=1;X=2), Det=yes).
X = 1 ;
X = 2,
Det = yes ;
~~~~~
This predicate is under consideration for inclusion into the ISO standard.
For compatibility with other Prolog implementations see `call_cleanup/2`.

/** @pred if(? _G_,? _H_,? _I_)
Call goal _H_ once per each solution of goal _H_. If goal
_H_ has no solutions, call goal _I_.
The built-in `if/3` is similar to `->/3`, with the difference
that it will backtrack over the test goal. Consider the following
small data-base:
~~~~~{.prolog}
a(1). b(a). c(x).
a(2). b(b). c(y).
~~~~~
Execution of an `if/3` query will proceed as follows:
~~~~~{.prolog}
?- if(a(X),b(Y),c(Z)).
X = 1,
Y = a ? ;
X = 1,
Y = b ? ;
X = 2,
Y = a ? ;
X = 2,
Y = b ? ;
no
~~~~~
The system will backtrack over the two solutions for `a/1` and the
two solutions for `b/1`, generating four solutions.
Cuts are allowed inside the first goal _G_, but they will only prune
over _G_.
If you want _G_ to be deterministic you should use if-then-else, as
it is both more efficient and more portable.

/** @pred leash(+ _M_)

prompt on Call and Redo

The initial leashing mode is `full`.
The user may also specify directly the debugger ports
where he wants to be prompted. If the argument for leash
is a number _N_, each of lower four bits of the number is used to
control prompting at one the ports of the box model. The debugger will
prompt according to the following conditions:

+ if `N/\ 2 =\= 0` prompt on redo
+ if `N/\ 4 =\= 0` prompt on exit
+ if `N/\ 8 =\= 0` prompt on call
Therefore, `leash(15)` is equivalent to `leash(full)` and
`leash(0)` is equivalent to `leash(off)`.
Another way of using `leash` is to give it a list with the names of
the ports where the debugger should stop. For example,
`leash([call,exit,redo,fail])` is the same as `leash(full)` or
`leash(15)` and `leash([fail])` might be used instead of

_Kind_ is silent.
If you need to report errors from your own predicates, we advise you to
stick to the existing error terms if you can; but should you need to
invent new ones, you can define corresponding error messages by
asserting clauses for `prolog:message/2`. You will need to declare

C-library `printf()` format specification used by write/1 and
friends to determine how floating point numbers are printed. The
default is `%.15g`. The specified value is passed to `printf()`
without further checking. For example, if you want less digits

If `on` allow garbage collection (default), if `off` disable it.
+ `gc_margin `
Set or show the minimum free stack before starting garbage
collection. The default depends on total stack size.

and stack shifts, if `on` inform when a garbage collection or stack
shift happened, if verbose give detailed information on garbage
collection and stack shifts. Last, if `very_verbose` give detailed
information on data-structures found during the garbage collection
process, namely, on choice-points.
+ `generate_debugging_info `
If `true` (default) generate debugging information for
procedures, including source mode. If `false` predicates no
information is generated, although debugging is still possible, and
source mode is disabled.
+ `host_type `
Return `configure` system information, including the machine-id
for which YAP was compiled and Operating System information.
+ `index `
If `on` allow indexing (default), if `off` disable it, if
`single` allow on first argument only.

Maximum bound on searching sub-terms for indexing, if `0` (default) no bound.
+ `informational_messages `

that are printed when consulting. If `off` disable printing
these messages. It is `on` by default except if YAP is booted with
the `-L` flag.
+ `integer_rounding_function is iso `
Read-only flag telling the rounding function used for integers. Takes the value
`toward_zero` for the current version of YAP.
+ `language `
Choose whether YAP is closer to C-Prolog, `cprolog`, iso-prolog,
`iso` or SICStus Prolog, `sicstus`. The current default is
`cprolog`. This flag affects update semantics, leashing mode,
style checking, handling calls to undefined procedures, how directives
are interpreted, when to use dynamic, character escapes, and how files
are consulted.
+ `max_arity is iso `
Read-only flag telling the maximum arity of a functor. Takes the value
`unbounded` for the current version of YAP.
+ `max_integer is iso `
Read-only flag telling the maximum integer in the
implementation. Depends on machine and Operating System
architecture, and on whether YAP uses the `GMP` multi-precision
library. If bounded is false, requests for max_integer
will fail.
+ `max_tagged_integer `
Read-only flag telling the maximum integer we can store as a single
word. Depends on machine and Operating System
architecture. It can be used to find the word size of the current machine.
+ `min_integer is iso `
Read-only flag telling the minimum integer in the
implementation. Depends on machine and Operating System architecture,
and on whether YAP uses the `GMP` multi-precision library. If
bounded is false, requests for min_integer will fail.
+ `min_tagged_integer `
Read-only flag telling the minimum integer we can store as a single
word. Depends on machine and Operating System
architecture.
+ `n_of_integer_keys_in_bb `
Read or set the size of the hash table that is used for looking up the
blackboard when the key is an integer.
+ `occurs_check `
Current read-only and set to `false`.
+ `n_of_integer_keys_in_db `
Read or set the size of the hash table that is used for looking up the
internal data-base when the key is an integer.
+ `open_expands_filename `
If `true` the open/3 builtin performs filename-expansion
before opening a file (SICStus Prolog like). If `false` it does not
(SWI-Prolog like).
+ `open_shared_object `
If true, `open_shared_object/2` and friends are implemented,
providing access to shared libraries (`.so` files) or to dynamic link
libraries (`.DLL` files).
+ `profiling `
If `off` (default) do not compile profiling information for
procedures. If `on` compile predicates so that they will output
profiling information. Profiling data can be read through the
profile_data/3 built-in.
+ `prompt_alternatives_on(atom, changeable) `
SWI-Compatible option, determines prompting for alternatives in the Prolog toplevel. Default is <tt>groundness</tt>, YAP prompts for alternatives if and only if the query contains variables. The alternative, default in SWI-Prolog is <tt>determinism</tt> which implies the system prompts for alternatives if the goal succeeded while leaving choicepoints.
+ `redefine_warnings `
If _Value_ is unbound, tell whether warnings for procedures defined
in several different files are `on` or
`off`. If _Value_ is bound to `on` enable these warnings,
and if it is bound to `off` disable them. The default for YAP is
`off`, unless we are in `sicstus` or `iso` mode.
+ `shared_object_search_path `
Name of the environment variable used by the system to search for shared
objects.
+ `shared_object_extension `
Suffix associated with loadable code.
+ `single_var_warnings `
If _Value_ is unbound, tell whether warnings for singleton variables
are `on` or `off`. If _Value_ is bound to `on` enable
these warnings, and if it is bound to `off` disable them. The
default for YAP is `off`, unless we are in `sicstus` or
`iso` mode.
+ `strict_iso `
If _Value_ is unbound, tell whether strict ISO compatibility mode
is `on` or `off`. If _Value_ is bound to `on` set
language mode to `iso` and enable strict mode. If _Value_ is
bound to `off` disable strict mode, and keep the current language
mode. The default for YAP is `off`.
Under strict ISO Prolog mode all calls to non-ISO built-ins generate an
error. Compilation of clauses that would call non-ISO built-ins will
also generate errors. Pre-processing for grammar rules is also
disabled. Module expansion is still performed.
Arguably, ISO Prolog does not provide all the functionality required
from a modern Prolog system. Moreover, because most Prolog
implementations do not fully implement the standard and because the
standard itself gives the implementor latitude in a few important
questions, such as the unification algorithm and maximum size for
numbers there is no guarantee that programs compliant with this mode
will work the same way in every Prolog and in every platform. We thus
believe this mode is mostly useful when investigating how a program
depends on a Prolog's platform specific features.
+ `stack_dump_on_error `
If `on` show a stack dump when YAP finds an error. The default is
`off`.
+ `syntax_errors`
Control action to be taken after syntax errors while executing read/1,
`read/2`, or `read_term/3`:
+ `dec10`
Report the syntax error and retry reading the term.
+ `fail`
Report the syntax error and fail (default).
+ `error`
Report the syntax error and generate an error.
+ `quiet`
Just fail
+ `system_options `
This read only flag tells which options were used to compile
YAP. Currently it informs whether the system supports `big_numbers`,
`coroutining`, `depth_limit`, `low_level_tracer`,
`or-parallelism`, `rational_trees`, `readline`, `tabling`,
`threads`, or the `wam_profiler`.
+ `tabling_mode`
Sets or reads the tabling mode for all tabled predicates. Please
(see Tabling) for the list of options.
+ `to_chars_mode `
Define whether YAP should follow `quintus`-like
semantics for the `atom_chars/1` or `number_chars/1` built-in,
or whether it should follow the ISO standard (`iso` option).
+ `toplevel_hook `
If bound, set the argument to a goal to be executed before entering the
top-level. If unbound show the current goal or `true` if none is
presented. Only the first solution is considered and the goal is not
backtracked into.
+ `toplevel_print_options `
If bound, set the argument to the `write_term/3` options used to write
terms from the top-level. If unbound, show the current options.
+ `typein_module `
If bound, set the current working or type-in module to the argument,
which must be an atom. If unbound, unify the argument with the current
working module.
+ `unix`
Read-only Boolean flag that unifies with `true` if YAP is
running on an Unix system. Defined if the C-compiler used to compile
this version of YAP either defines `__unix__` or `unix`.
+ `unknown is iso`
Corresponds to calling the unknown/2 built-in. Possible values
are `error`, `fail`, and `warning`.
+ `update_semantics `
Define whether YAP should follow `immediate` update
semantics, as in C-Prolog (default), `logical` update semantics,
as in Quintus Prolog, SICStus Prolog, or in the ISO standard. There is
also an intermediate mode, `logical_assert`, where dynamic
procedures follow logical semantics but the internal data base still
follows immediate semantics.
+ `user_error `
If the second argument is bound to a stream, set user_error to
this stream. If the second argument is unbound, unify the argument with
the current user_error stream.
By default, the user_error stream is set to a stream
corresponding to the Unix `stderr` stream.
The next example shows how to use this flag:
~~~{.prolog}
?- open( '/dev/null', append, Error,
[alias(mauri_tripa)] ).
Error = '$stream'(3) ? ;
no
?- set_prolog_flag(user_error, mauri_tripa).
close(mauri_tripa).
yes
?-
~~~
We execute three commands. First, we open a stream in write mode and
give it an alias, in this case `mauri_tripa`. Next, we set
user_error to the stream via the alias. Note that after we did so
prompts from the system were redirected to the stream
`mauri_tripa`. Last, we close the stream. At this point, YAP
automatically redirects the user_error alias to the original
`stderr`.
+ `user_flags `
Define the behaviour of set_prolog_flag/2 if the flag is not known. Values are `silent`, `warning` and `error`. The first two create the flag on-the-fly, with `warning` printing a message. The value `error` is consistent with ISO: it raises an existence error and does not create the flag. See also `create_prolog_flag/3`. The default is`error`, and developers are encouraged to use `create_prolog_flag/3` to create flags for their library.
+ `user_input `
If the second argument is bound to a stream, set user_input to
this stream. If the second argument is unbound, unify the argument with
the current user_input stream.
By default, the user_input stream is set to a stream
corresponding to the Unix `stdin` stream.
+ `user_output `
If the second argument is bound to a stream, set user_output to
this stream. If the second argument is unbound, unify the argument with
the current user_output stream.
By default, the user_output stream is set to a stream
corresponding to the Unix `stdout` stream.
+ `verbose `
If `normal` allow printing of informational and banner messages,
such as the ones that are printed when consulting. If `silent`
disable printing these messages. It is `normal` by default except if
YAP is booted with the `-q` or `-L` flag.
+ `verbose_load `
If `true` allow printing of informational messages when
consulting files. If `false` disable printing these messages. It
is `normal` by default except if YAP is booted with the `-L`
flag.
+ `version `
Read-only flag that returns an atom with the current version of
YAP.
+ `version_data `
Read-only flag that reads a term of the form
`yap`( _Major_, _Minor_, _Patch_, _Undefined_), where
_Major_ is the major version, _Minor_ is the minor version,
and _Patch_ is the patch number.
+ `windows `
Read-only boolean flag that unifies with tr `true` if YAP is
running on an Windows machine.
+ `write_strings `
Writable flag telling whether the system should write lists of
integers that are writable character codes using the list notation. It
is `on` if enables or `off` if disabled. The default value for
this flag is `off`.
+ `max_workers `
Read-only flag telling the maximum number of parallel processes.
+ `max_threads `
Read-only flag telling the maximum number of Prolog threads that can
be created.

Dynamic predicate, normally not defined. Called by the Prolog system on run-time exceptions that can be repaired `just-in-time`. The values for _Exception_ are described below. See also catch/3 and throw/1.
If this hook predicate succeeds it must instantiate the _Action_ argument to the atom `fail` to make the operation fail silently, `retry` to tell Prolog to retry the operation or `error` to make the system generate an exception. The action `retry` only makes sense if this hook modified the environment such that the operation can now succeed without error.

_Context_ is instantiated to a predicate-indicator ( _Module:Name/Arity_). If the predicate fails Prolog will generate an existence_error exception.

See also `unknown`.

/** @pred format(+ _T_,+ _L_)
Print formatted output to the current output stream. The arguments in
list _L_ are output according to the string or atom _T_.
A control sequence is introduced by a `w`. The following control
sequences are available in YAP:
+ `~~`
Print a single tilde.
+ `~a`
The next argument must be an atom, that will be printed as if by `write`.
+ `~Nc`
The next argument must be an integer, that will be printed as a
character code. The number _N_ is the number of times to print the
character (default 1).
+ `~Ne`
+ `~NE`
+ `~Nf`
+ `~Ng`
+ `~NG`
The next argument must be a floating point number. The float _F_, the number
_N_ and the control code `c` will be passed to `printf` as:
~~~~~{.prolog}
printf("%s.Nc", F)
~~~~~
As an example:
~~~~~{.prolog}
?- format("~8e, ~8E, ~8f, ~8g, ~8G~w",
[3.14,3.14,3.14,3.14,3.14,3.14]).
3.140000e+00, 3.140000E+00, 3.140000, 3.14, 3.143.14
~~~~~
+ `~Nd`
The next argument must be an integer, and _N_ is the number of digits
after the decimal point. If _N_ is `0` no decimal points will be
printed. The default is _N = 0_.
~~~~~{.prolog}
?- format("~2d, ~d",[15000, 15000]).
150.00, 15000
~~~~~
+ `~ND`
Identical to `~Nd`, except that commas are used to separate groups
of three digits.
~~~~~{.prolog}
?- format("~2D, ~D",[150000, 150000]).
1,500.00, 150,000
~~~~~
+ `~i`
Ignore the next argument in the list of arguments:
~~~~~{.prolog}
?- format('The ~i met the boregrove',[mimsy]).
The met the boregrove
~~~~~
+ `~k`
Print the next argument with `write_canonical`:
~~~~~{.prolog}
?- format("Good night ~k",a+[1,2]).
Good night +(a,[1,2])
~~~~~
+ `~Nn`
Print _N_ newlines (where _N_ defaults to 1).
+ `~NN`
Print _N_ newlines if at the beginning of the line (where _N_
defaults to 1).
+ `~Nr`
The next argument must be an integer, and _N_ is interpreted as a
radix, such that `2 <= N <= 36` (the default is 8).
~~~~~{.prolog}
?- format("~2r, 0x~16r, ~r",
[150000, 150000, 150000]).
100100100111110000, 0x249f0, 444760
~~~~~
Note that the letters `a-z` denote digits larger than 9.
+ `~NR`
Similar to `~NR`. The next argument must be an integer, and _N_ is
interpreted as a radix, such that `2 <= N <= 36` (the default is 8).
~~~~~{.prolog}
?- format("~2r, 0x~16r, ~r",
[150000, 150000, 150000]).
100100100111110000, 0x249F0, 444760
~~~~~
The only difference is that letters `A-Z` denote digits larger than 9.
+ `~p`
Print the next argument with print/1:
~~~~~{.prolog}
?- format("Good night ~p",a+[1,2]).
Good night a+[1,2]
~~~~~
+ `~q`
Print the next argument with writeq/1:
~~~~~{.prolog}
?- format("Good night ~q",'Hello'+[1,2]).
Good night 'Hello'+[1,2]
~~~~~
+ `~Ns`
The next argument must be a list of character codes. The system then
outputs their representation as a string, where _N_ is the maximum
number of characters for the string ( _N_ defaults to the length of the
string).
~~~~~{.prolog}
?- format("The ~s are ~4s",["woods","lovely"]).
The woods are love
~~~~~
+ `~w`
Print the next argument with write/1:
~~~~~
?- format("Good night ~w",'Hello'+[1,2]).
Good night Hello+[1,2]
~~~~~
The number of arguments, `N`, may be given as an integer, or it
may be given as an extra argument. The next example shows a small
procedure to write a variable number of `a` characters:
~~~~~
write_many_as(N) :-
format("~*c",[N,0'a]).
~~~~~
The format/2 built-in also allows for formatted output. One can
specify column boundaries and fill the intermediate space by a padding
character:
+ `~N|`
Set a column boundary at position _N_, where _N_ defaults to the
current position.
+ `~N+`
Set a column boundary at _N_ characters past the current position, where
_N_ defaults to `8`.
+ `~Nt`
Set padding for a column, where _N_ is the fill code (default is
`SPC`).
The next example shows how to align columns and padding. We first show
left-alignment:
~~~~~
?- format("~n*Hello~16+*~n",[]).
*Hello *
~~~~~
Note that we reserve 16 characters for the column.
The following example shows how to do right-alignment:
~~~~~
?- format("*~tHello~16+*~n",[]).
* Hello*
~~~~~
The `~t` escape sequence forces filling before `Hello`.
We next show how to do centering:
~~~~~
?- format("*~tHello~t~16+*~n",[]).
* Hello *
~~~~~
The two `~t` escape sequence force filling both before and after
`Hello`. Space is then evenly divided between the right and the
left sides.

A special case is made, where if _Callable_ is bound to
`default`, then the default handler is restored for that signal.
A call in the form `on_signal( _S_, _H_, _H_)` can be used
to retrieve a signal's current handler without changing it.
It must be noted that although a signal can be received at all times,
the handler is not executed while YAP is waiting for a query at the
prompt. The signal will be, however, registered and dealt with as soon
as the user makes a query.
Please also note, that neither POSIX Operating Systems nor YAP guarantee
that the order of delivery and handling is going to correspond with the
order of dispatch.

/** @pred alarm(+ _Seconds_,+ _Callable_,+ _OldAlarm_)
Arranges for YAP to be interrupted in _Seconds_ seconds, or in
[ _Seconds_| _MicroSeconds_]. When interrupted, YAP will execute
_Callable_ and then return to the previous execution. If
_Seconds_ is `0`, no new alarm is scheduled. In any event,
any previously set alarm is canceled.
The variable _OldAlarm_ unifies with the number of seconds remaining
until any previously scheduled alarm was due to be delivered, or with
`0` if there was no previously scheduled alarm.
Note that execution of _Callable_ will wait if YAP is
executing built-in predicates, such as Input/Output operations.
The next example shows how _alarm/3_ can be used to implement a
simple clock:
~~~~~
loop :- loop.
ticker :- write('.'), flush_output,
get_value(tick, yes),
alarm(1,ticker,_).
:- set_value(tick, yes), alarm(1,ticker,_), loop.
~~~~~
The clock, `ticker`, writes a dot and then checks the flag
`tick` to see whether it can continue ticking. If so, it calls
itself again. Note that there is no guarantee that the each dot
corresponds a second: for instance, if the YAP is waiting for
user input, `ticker` will wait until the user types the entry in.
The next example shows how alarm/3 can be used to guarantee that
a certain procedure does not take longer than a certain amount of time:
~~~~~
loop :- loop.
:- catch((alarm(10, throw(ball), _),loop),
ball,
format('Quota exhausted.~n',[])).
~~~~~
In this case after `10` seconds our `loop` is interrupted,
`ball` is thrown, and the handler writes `Quota exhausted`.
Execution then continues from the handler.
Note that in this case `loop/0` always executes until the alarm is
sent. Often, the code you are executing succeeds or fails before the
alarm is actually delivered. In this case, you probably want to disable
the alarm when you leave the procedure. The next procedure does exactly so:
~~~~~
once_with_alarm(Time,Goal,DoOnAlarm) :-
catch(execute_once_with_alarm(Time, Goal), alarm, DoOnAlarm).
execute_once_with_alarm(Time, Goal) :-
alarm(Time, alarm, _),
( call(Goal) -> alarm(0, alarm, _) ; alarm(0, alarm, _), fail).
~~~~~
The procedure `once_with_alarm/3` has three arguments:
the _Time_ to wait before the alarm is
sent; the _Goal_ to execute; and the goal _DoOnAlarm_ to execute
if the alarm is sent. It uses catch/3 to handle the case the
`alarm` is sent. Then it starts the alarm, calls the goal
_Goal_, and disables the alarm on success or failure.

The example shows how much memory the system spends. Memory is divided
into Program Space, Stack Space and Trail. In the example we have 3MB
allocated for program spaces, with less than half being actually
used. YAP also shows the maximum amount of heap space having been used
which was over 2MB.
The stack space is divided into two stacks which grow against each
other. We are in the top level so very little stack is being used. On
the other hand, the system did use a lot of global and local stack
during the previous execution (we refer the reader to a WAM tutorial in
order to understand what are the global and local stacks).
YAP also shows information on how many memory overflows and garbage
collections the system executed, and statistics on total execution
time. Cputime includes all running time, runtime excludes garbage
collection and stack overflow time.

compiled WAM-like code directly from the trie data
structure. This reduces the loading time when backtracking, but
the order in which answers are obtained is undefined.

Defines that, by default, when a call to predicate _P_ is

were found. Somewhat less efficient but creates less choice-points.
The default tabling mode for a new tabled predicate is `batched`
and `exec_answers`. To set the tabling mode for all predicates at

/** @pred mutex_lock(+ _MutexId_)
Lock the mutex. Prolog mutexes are <em>recursive</em> mutexes: they
can be locked multiple times by the same thread. Only after unlocking
it as many times as it is locked, the mutex becomes available for
locking by other threads. If another thread has locked the mutex the
calling thread is suspended until to mutex is unlocked.
If _MutexId_ is an atom, and there is no current mutex with that
name, the mutex is created automatically using mutex_create/1. This
implies named mutexes need not be declared explicitly.
Please note that locking and unlocking mutexes should be paired
carefully. Especially make sure to unlock mutexes even if the protected
code fails or raises an exception. For most common cases use
with_mutex/2, which provides a safer way for handling Prolog-level
mutexes.

`true` cannot be joined. See also current_thread/2.
A thread that has been completed without thread_join/2 being
called on it is partly reclaimed: the Prolog stacks are released and the
C-thread is destroyed. A small data-structure representing the
exit-status of the thread is retained until thread_join/2 is called on
the thread. Defined values for _Status_ are:
+ true
The goal has been proven successfully.
+ false
The goal has failed.
+ exception( _Term_)
The thread is terminated on an
exception. See print_message/2 to turn system exceptions into
readable messages.
+ exited( _Term_)
The thread is terminated on thread_exit/1 using the argument _Term_.
+ thread_detach(+ _Id_)
Switch thread into detached-state (see `detached` option at
thread_create/3 at runtime. _Id_ is the identifier of the thread
placed in detached state.
One of the possible applications is to simplify debugging. Threads that
are created as `detached` leave no traces if they crash. For
not-detached threads the status can be inspected using
current_thread/2. Threads nobody is waiting for may be created
normally and detach themselves just before completion. This way they
leave no traces on normal completion and their reason for failure can be
inspected.

/** @pred use_foreign_library(+ _FileSpec_) is det
use_foreign_library(+ _FileSpec_, + _Entry_:atom) is det
Load and install a foreign library as load_foreign_library/1
and `load_foreign_library/2` and
register the installation using `initialization/2` with the option
now. This is similar to using:
~~~~~
:- initialization(load_foreign_library(foreign(mylib))).
~~~~~
but using the initialization/1 wrapper causes the library to
be loaded after loading of the file in which it appears is
completed, while use_foreign_library/1 loads the library
immediately. I.e. the difference is only relevant if the remainder
of the file uses functionality of the `C`-library.

/** @pred load_foreign_library(: _FileSpec_, + _Entry_:atom) is det
Load a shared object or DLL. After loading the _Entry_ function is
called without arguments. The default entry function is composed
from `install_`, followed by the file base-name. E.g., the
load-call below calls the function `install_mylib()`. If the platform
prefixes extern functions with `_`, this prefix is added before
calling.

_FileSpec_ is a specification for
absolute_file_name/3. If searching the file fails, the plain
name is passed to the OS to try the default method of the OS for
locating foreign objects. The default definition of
file_search_path/2 searches <prolog home>/lib/Yap.

`use_foreign_library/1,2` are intended for use in
directives.
