macro

Inherits string.

Definition

Representation of a preprocessor macro.

Construct a new macro definition.

A macro stores its identifier together with the metadata required during expansion:

• replacement text,
• formal parameter list,
• variadic status,
• cycle detection flags,
• temporary activation state.

The type extends string so that the macro name itself behaves as a string value.

Examples

Object-like macro:

   type(macro) :: m
   m = macro('PI', '3.1415926535')

Function-like macro:

   type(macro) :: m
   m = macro('SQR(x)', '((x)*(x))')

Constructors

Initializes a new instance of the Macro Expansion class

Constructor

type(macro) function macro(character(*) name, (optional) character(*) val) 

Parameters

[in]	name	macro name
[in]	val	(optional) value of the macro

Examples

type(macro) :: m
m = macro('_WIN32')

Returns

The constructed macro object.

Creates an initialized Macro Expansion object with the specified name and optional replacement text.

Parameter lists are initialized to empty, variadic expansion is disabled, and direct self-references are marked as cyclic.

Parameters

[in]	name	Macro identifier.
[in]	val	Replacement text (default: empty).

Returns

Initialized macro object.
