-Formatting C++ Lambda Expressions
-#################################
-
-Uncrustify supports some formatting of c++ lambda expressions, although
-the support is incomplete.
-The parts of c++ lambda expressions that are currently recognized by Uncrusitify
-are:
-
-.. code-block:: c++
-
- [ captures ] execution_context ( params ) specifiers -> ret { body }
-
-Explanations for all the tokens in the above lambda expression
-(except for ``execution_context``),
-as well as a complete description of c++ lambda expressions,
-are found `here <https://en.cppreference.com/w/cpp/language/lambda>`_.
-The ``execution_context`` token is a non-standard addition to allow for
-specification of the execution space (e.g. host or device in CUDA).
-The native specifiers for the `execution_context` for lambda expression in CUDA
-are ``__device__`` and ``__host__ __device__``.
-However, it is common for code to use a preprocessor variable in place of the
-native specifiers.
-
-The Uncrustify options for formatting of c++ lambda expressions are:
-
-.. code-block::
-
- sp_cpp_lambda_assign
- sp_cpp_lambda_square_paren
- sp_cpp_lambda_square_brace
- sp_cpp_lambda_paren_brace
- sp_cpp_lambda_fparen
- nl_cpp_lambda_leave_one_liners
- nl_cpp_ldef_brace
- indent_cpp_lambda_body
- indent_cpp_lambda_only_once
-
-Please refer to the example configuration file at
-`uncrustify/documentation/htdocs/default.cfg <https://github.com/uncrustify/uncrustify/blob/master/documentation/htdocs/default.cfg>`_
-for an explanation of the options.
-Additionally, a multiple number of ``execution_context`` tokens may be set in
-the configuration file:
-
-.. code-block::
-
- set EXECUTION_CONTEXT __host__ __device__
- set EXECUTION_CONTEXT DEVICE_LAMBDA_CONTEXT HOST_DEVICE_LAMBDA_CONTEXT
-
-The effect of these lines in the configuration file is that any of the strings
-(``__host__``, ``__device__``,
-``DEVICE_LAMBDA_CONTEXT``, ``HOST_DEVICE_LAMBDA_CONTEXT``)
-will be recognized by uncrusitfy
-and will allow the lambda to be properly identified.
-Note that each word after the token name
-(``EXECUTION_CONTEXT`` in this instance) is a separate token.
-This means that uncrustify will parse ``__host__`` and ``__device__``
-as separate tokens, and there is no need to specify ``__device__`` twice.
