Function Documentation

ya_t ya_branch	(	const char *restrict	name,
			...
	)

Create an ya node.

Create a node from subnodes. This will free memory used by the subnodes. If a list is added to a branch, then the nodes of the list are added to the created node, instead of the list itself.

Parameters:

	name	Name of the node.
	...	The subnodes, ending with NULL

Returns:

A new AST NODE.

ya_t ya_list	(	const char *restrict	name,
			...
	)

Create an ya node.

Create a list of subnodes, when included in a list or node, it expands as if the contents was passed as seperate items. This also free memory used by the subnodes.

Parameters:

	name	Name of the node. This should be '@list' because this function is called from the YA_LIST macro.
	...	The subnodes, ending with NULL

Returns:

A new AST NODE.

void ya_node_save	(	FILE *	output_file,
		ya_t *	node
	)

Save the node to a file.

Parameters:

	output_file	A file pointer of an file open for writing.
	node	The node to be saved to file.
