while

-----

|
|
|

|
|
Evaluate a group of commands while a condition is true
|
||
|
|
|
||
|
|
.. code-block:: cmake
|
||
|
|
|
||
|
|
while(<condition>)
|
||
|
|
<commands>
|
||
|
|
endwhile()
|
||
|
|
|
||
|
|
All commands between while and the matching :command:`endwhile` are recorded
|
||
|
|
without being invoked. Once the :command:`endwhile` is evaluated, the
|
||
|
|
recorded list of commands is invoked as long as the ``<condition>`` is true.
|
||
|
|
|
||
|
|
The ``<condition>`` has the same syntax and is evaluated using the same logic
|
||
|
|
as described at length for the :command:`if` command.
|
||
|
|
|
||
|
|
The commands :command:`break` and :command:`continue` provide means to
|
||
|
|
escape from the normal control flow.
|
||
|
|
|
||
|
|
Per legacy, the :command:`endwhile` command admits
|
||
|
|
an optional ``<condition>`` argument.
|
||
|
|
If used, it must be a verbatim repeat of the argument of the opening
|
||
|
|
``while`` command.
