``logtalk_make/0``
==================

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

::

   logtalk_make

Reloads all Logtalk source files that have been modified since the time
they were last loaded. Only source files loaded using the
:ref:`predicates_logtalk_load_1` and :ref:`predicates_logtalk_load_2`
predicates are reloaded. Non-modified files will also be reloaded when
a previous attempt to load them failed or 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 predicate reloads its
main file (i.e., the file that contains the :ref:`directives_include_1`
directive).

Depending on the :term:`backend Prolog compiler`, the shortcut ``{*}`` may
be used as an alternative. Check the :term:`adapter files <adapter file>`
for the availability of the shortcut as it is not part of the language.

.. warning::

   Only use the ``{*}`` shortcut at the top-level interpreter and
   never in source files.

This predicate can be extended by the user by defining clauses for the
:ref:`predicates_logtalk_make_target_action_1` multifile and dynamic hook
predicate using the argument ``all``. The additional user defined actions
are run after the default one.
