@addtogroup absolute_file_name
@pred absolute_file_name(+File:atom, +Options:list, +Path:atom) is nondet
@pred absolute_file_name(-File:atom, +Path:atom, +Options:list) is nondet
_Options_ is a list of options to guide the conversion:
- extensions(+ _ListOfExtensions_)
List of file-name suffixes to add to try adding to the file. The
Default is the empty suffix, `''`. For each extension,
absolute_file_name/3 will first add the extension and then verify
the conditions imposed by the other options. If the condition
fails, the next extension of the list is tried. Extensions may
be specified both with dot, as `.ext`, or without, as plain
`ext`.
- relative_to(+ _FileOrDir_ )
Resolve the path relative to the given directory or directory the
holding the given file. Without this option, paths are resolved
relative to the working directory (see working_directory/2) or,
if _Spec_ is atomic and absolute_file_name/3 is executed
in a directive, it uses the current source-file as reference.
- access(+ _Mode_ )
Imposes the condition access_file( _File_ , _Mode_ ). _Mode_ is one of `read`, `write`, `append`, `exist` or
`none` (default).
See also access_file/2.
- file_type(+ _Type_ )
Defines suffixes matching one of several pre-specified type of files. Default mapping is as follows:
1. `txt` implies `[ '' ]`,
2. `prolog` implies `['.yap', '.pl', '.prolog', '']`,
3. `executable` implies `['.so', ',dylib', '.dll']` depending on the Operating system,
4. `qly` implies `['.qly', '']`,
5. `directory` implies `['']`,
6. The file-type `source` is an alias for `prolog` designed to support compatibility with SICStus Prolog. See also prolog_file_type/2.
Notice that this predicate only
returns non-directories, unless the option `file_type(directory)` is
specified, or unless `access(none)`.
- file_errors(`fail`/`error`)
If `error` (default), throw `existence_error` exception
if the file cannot be found. If `fail`, stay silent.
- solutions(`first`/`all`)
If `first` (default), commit to the first solution. Otherwise
absolute_file_name will enumerate all solutions via backtracking.
- expand(`true`/`false`)
If `true` (default is `false`) and _Spec_ is atomic, call
expand_file_name/2 followed by member/2 on _Spec_ before
proceeding. This is originally a SWI-Prolog extension, but
whereas SWI-Prolog implements its own conventions, YAP uses the
shell's `glob` primitive.
- glob(`Pattern`)
If _Pattern_ is atomic, add the pattern as a suffix to the current expansion, and call
expand_file_name/2 followed by member/2 on the result. This is originally a SICStus Prolog exception.
Both `glob` and `expand` rely on the same underlying
mechanism. YAP gives preference to `glob`.
- verbose_file_search(`true`/`false`)
If `true` (default is `false`) output messages during
search. This is often helpful when debugging. Corresponds to the
SWI-Prolog flag `verbose_file_search` (also available in YAP).
Compatibility considerations to common argument-order in ISO as well
as SICStus absolute_file_name/3 forced us to be flexible here.
If the last argument is a list and the second not, the arguments are
swapped, making the call
~~~~~~~~~~~prolog
absolute_file_name(+ _Spec_ , - _Path_ ,+ _Options_ )
~~~~~~~~~~~
valid as well.
@pred user:library_directory(?Directory:atom) is nondet, dynamic
Dynamic, multi-file predicate that succeeds when _Directory_ is a
current library directory name. Asserted in the user module.
Library directories are the places where files specified in the form
`library( _File_ )` are searched by the predicates consult/1,
reconsult/1, use_module/1, ensure_loaded/1, and load_files/2.
This directory is initialized by a rule that calls the system predicate
system_library/1.

Notice that in `glob` mode YAP will fail if it cannot find a matching file, as `glob`
implicitely tests for existence when checking for patterns.

* - debugging of backtrable user-C preds would core dump.
* - redeclaring a C-predicate as Prolog core dumps.
* - badly protected YapInterface.h.
* - break/0 was failing at exit.
* - YAP_cut_fail and YAP_cut_succeed were different from manual.

* NEW: yap_flag(tabling_mode,MODE) changes the tabling execution mode of all tabled predicates to MODE (batched, local or default).
* NEW: tabling_mode(PRED,MODE) changes the default tabling execution mode of predicate PRED to MODE (batched or local).

/** @defgroup YAPError Error Handling
@ingroup YAPControl
The error handler is called when there is an execution error or a
warning needs to be displayed. The handlers include a number of hooks
to allow user-control.
Errors are terms of the form:
- error( domain_error( Domain, Culprit )`
- error( evaluation_error( Expression, Culprit )`
- error( existence_error( Object, Culprit )`
- error( instantiation_error )`
- error( permission_error( Error, Permission, Culprit)`
- error( representation_error( Domain, Culprit )`
- error( resource_error( Resource, Culprit )`
- error( syntax_error( Error )`
- error( system_error( Domain, Culprit )`
- error( type_error( Type, Culprit )`
- error( uninstantiation_error( Culprit )`
