Function Documentation

ya_t ya_binary_float	(	const char *restrict	name,
		const char *restrict	buf,
		size_t	buf_size,
		int	base,
		int	nr_bits
	)

Create literal node from floating point literal string.

Parameters:

	name	name of the node.
	buf	Literal as string.
	buf_size	String size.
	base
	nr_bits	Nr of bits in the floating point format, only 64 bits is supported.

Returns:

The decoded literal node.

ya_t ya_integer	(	const char *restrict	name,
		ya_type_t	type,
		const char *restrict	buf,
		size_t	buf_size,
		int	base
	)

Create literal from an integer literal string.

The RFC 4648 is used as a guide for encoding integers.

• Base 0, has no alphabet, it always yields zero.
• Base 1-31 and 33-36, These bases are encoded following an extended Base-16
• Base 32, Base-32 is encoding
• Base 37-64 These bases are encoded following Base-64

Parameters:

	name	name of the node.
	type	type of node, should be either YA_NODE_TYPE_POSITIVE_INTEGER or YA_NODE_TYPE_NEGATIVE_INTEGER.
	buf	Literal as string.
	buf_size	String size.
	base	The base of the literal. 0-64

Returns:

The decoded literal.

ya_t ya_literal	(	const char *restrict	name,
		ya_type_t	type,
		const void *restrict	buf,
		size_t	buf_size
	)

ya_t ya_negative_integer	(	const char *restrict	name,
		const char *restrict	buf,
		size_t	buf_size,
		int	base
	)

Create literal from an negative integer literal string.

The RFC 4648 is used as a guide for encoding integers. The integer literal should be passed without the base prefix (0x) or suffix (h). The integer literal should be passed without the negative sign (-).

• Base 0, has no alphabet, it always yields zero.
• Base 1-31 and 33-36, These bases are encoded following an extended Base-16
• Base 32, Base-32 is encoding
• Base 37-64 These bases are encoded following Base-64

Parameters:

	name	name of the node.
	buf	Literal as string.
	buf_size	String size.
	base	The base of the literal. 0-64

Returns:

The decoded literal.
