================
static_let macro
================

The static_let module implements static_let pattern, which allows declaration of private global variables which are local to a scope.

All functions and symbols are in "static_let" module, use require to get access to it. ::

    require daslib/static_let

.. _handle-static_let-StaticLetMacro:

.. das:attribute:: StaticLetMacro

This macro implements the `static_let` and `static_let_finalize` functions.

.. _function-static_let_static_let_block_ls__c_void_gr_:

.. das:function:: static_let(blk: block<():void>)

Given a scope with the variable declarations, this function will make those variables global.
Variable will be renamed under the hood, and all local access to it will be renamed as well.

:Arguments: * **blk** : block<void>

.. _function-static_let_static_let_string_block_ls__c_void_gr_:

.. das:function:: static_let(name: string; blk: block<():void>)

Given a scope with the variable declarations, this function will make those variables global.
Variable will be renamed under the hood, and all local access to it will be renamed as well.

:Arguments: * **name** : string

            * **blk** : block<void>

.. _function-static_let_static_let_finalize_block_ls__c_void_gr_:

.. das:function:: static_let_finalize(blk: block<():void>)

This is very similar to regular static_let, but additionally the variable will be deleted on the context shutdown.

:Arguments: * **blk** : block<void>
