While the behavior is identical -to the legacy implementation in most cases, some corner cases were -cleaned up to simplify the behavior. Specifically: - -* Expansion of ``@VAR@`` reference syntax defined by the - :command:`configure_file` and :command:`string(CONFIGURE)` - commands is no longer performed in other contexts. - -* Literal ``${VAR}`` reference syntax may contain only - alphanumeric characters (``A-Z``, ``a-z``, ``0-9``) and - the characters ``_``, ``.``, ``/``, ``-``, and ``+``. - Variables with other characters in their name may still - be referenced indirectly, e.g. - - .. code-block:: cmake - - set(varname "otherwise & disallowed $ characters") - message("${${varname}}") - -* The setting of policy :policy:`CMP0010` is not considered, - so improper variable reference syntax is always an error. - -* More characters are allowed to be escaped in variable names. - Previously, only ``()#" \@^`` were valid characters to - escape. Now any non-alphanumeric, non-semicolon, non-NUL - character may be escaped following the ``escape_identity`` - production in the :ref:`Escape Sequences` section of the - :manual:`cmake-language(7)` manual. - -The ``OLD`` behavior for this policy is to honor the legacy behavior for -variable references and escape sequences. The ``NEW`` behavior is to -use the simpler variable expansion and escape sequence evaluation rules. - -This policy was introduced in CMake version 3.1. -CMake version |release| warns when the policy is not set and uses -``OLD`` behavior. Use the :command:`cmake_policy` command to set -it to ``OLD`` or ``NEW`` explicitly. - -.. include:: DEPRECATED.txt |
