Description
-----------

::

   logtalk_make(Target)

Runs a make target. Fails of the target is not valid.

Allows reloading all Logtalk source files that have been modified since
last loaded when called with the target ``all``, deleting all
intermediate files generated by the compilation of Logtalk source files
when called with the target ``clean``, checking for code issues when
called with the target ``check``, listing of circular dependencies
between pairs or trios of objects when called with the target
``circular``, generating documentation when called with the target
``documentation``, and deleting the dynamic binding caches with the
target ``caches``.

There are also three variants of the ``all`` target: ``debug``,
``normal``, and ``optimal``. These targets change the compilation mode
(by changing the default value of the :ref:`debug <flag_debug>` and
:ref:`optimize <flag_optimize>` flags) and reload all affected files 
(i.e. all files loaded without an explicit ``debug/1`` or ``optimize/1``
compiler option).

When using the ``all`` target, only source files loaded using the
``logtalk_load/1-2`` predicates are reloaded. Non-modified files will
also be reloaded when there is a change to the compilation mode (i.e.
when the files were loaded without explicit :ref:`debug <flag_debug>` or
:ref:`optimize <flag_optimize>` flags and the default values of these
flags changed after loading; no check is made, however, for other implicit
compiler flags that may have changed since loading). When an included file
is modified, this target reloads its main file (i.e. the file that contains
the :ref:`directives_include_1` directive).

When using the ``check`` or ``circular`` targets, be sure to compile
your source files with the :ref:`source_data <flag_source_data>` flag
turned on for complete and detailed reports.

When using the ``check`` target, predicates for messages sent to objects
that implement the :ref:`forwarding <apis:forwarding/0>` built-in protocol
are not reported. While this usually avoids only false positives, it may
also result in failure to report true missing predicates in some cases.

When using the ``circular`` target, be prepared for a lengthy
computation time for applications with a large combined number of
objects and message calls. Only mutual and triangular dependencies are
checked due to the computational cost.

The ``documentation`` target requires the ``doclet`` tool and a single
*doclet* object to be loaded. See the ``doclet`` tool for more details.

Depending on the backend Prolog compiler, the following top-level shortcuts
are usually defined:

* ``{*}`` - ``logtalk_make(all)``
* ``{!}`` - ``logtalk_make(clean)``
* ``{?}`` - ``logtalk_make(check)``
* ``{@}`` - ``logtalk_make(circular)``
* ``{#}`` - ``logtalk_make(documentation)``
* ``{$}`` - ``logtalk_make(caches)``
* ``{+d}`` - ``logtalk_make(debug)``
* ``{+n}`` - ``logtalk_make(normal)``
* ``{+o}`` - ``logtalk_make(optimal)``

Check the adapter files for the availability of these shortcuts as they are
not part of the language (and thus should only be used at the top-level
interpreter).

The target actions can be extended by defining clauses for the multifile
and dynamic hook predicate ``logtalk_make_target_action(Target)`` where
``Target`` is one of the targets listed above. The additional user
defined actions are run after the default ones.
