Definition

Evaluates a preprocessor-style expression with macro substitution. Tokenizes the input expression, expands macros where appropriate, parses it according to operator precedence, and computes the integer result. Returns .true. if evaluation succeeded and the result is non-zero.

evaluate(character(*), type(macros)(:), integer)

logical function evaluate(expr, macros, val)

Parameters

[in]	expr	Expression string to evaluate
[in,out]	macros	Array of defined macros for substitution and defined() checks
[out]	val	(optional) integer result of the evaluation

Returns: .true. if the expression evaluated successfully to non-zero, .false. otherwise

evaluate(character(*), type(macros)(:), type(context), integer)

logical function evaluate(expr, macros, ctx, val)

Parameters

[in]	expr	Expression string to evaluate
[in,out]	macros	Array of defined macros for substitution and defined() checks
[in]	ctx	Current context
[out]	val	(optional) integer result of the evaluation

Returns: .true. if the expression evaluated successfully to non-zero, .false. otherwise

Methods

◆ evaluate_expression_default()

logical function evaluate_expression_default	(	character(*), intent(in)	expr,
		type(macro), dimension(:), intent(inout), allocatable	macros,
		integer, intent(out), optional	val )

Evaluates a preprocessor-style expression with macro substitution. Tokenizes the input expression, expands macros where appropriate, parses it according to operator precedence, and computes the integer result. Returns .true. if evaluation succeeded and the result is non-zero.

Parameters

[in]	expr	Expression string to evaluate
[in,out]	macros	Array of defined macros for substitution and defined() checks
[out]	val	(optional) integer result of the evaluation

Returns: .true. if the expression evaluated successfully to non-zero, .false. otherwise

Remarks

◆ evaluate_expression_with_context()

logical function evaluate_expression_with_context	(	character(*), intent(in)	expr,
		type(macro), dimension(:), intent(inout), allocatable	macros,
		type(context), intent(in)	ctx,
		integer, intent(out), optional	val )

Evaluates a preprocessor-style expression with macro substitution. Tokenizes the input expression, expands macros where appropriate, parses it according to operator precedence, and computes the integer result. Returns .true. if evaluation succeeded and the result is non-zero.

Parameters

[in]	expr	Expression string to evaluate
[in,out]	macros	Array of defined macros for substitution and defined() checks
[in]	ctx	Context
[out]	val	(optional) integer result of the evaluation

Returns: .true. if the expression evaluated successfully to non-zero, .false. otherwise
