LOWDOWN_TREE_RNDR(3)   FreeBSD Library Functions Manual	  LOWDOWN_TREE_RNDR(3)

NAME
     lowdown_tree_rndr -- render Markdown into debugging output

LIBRARY
     library "liblowdown"

SYNOPSIS
     #include <sys/queue.h>
     #include <stdio.h>
     #include <lowdown.h>

     void
     lowdown_tree_rndr(struct lowdown_buf *out,	struct lowdown_metaq *mq,
	 void *arg, const struct lowdown_node *n);

DESCRIPTION
     Renders a node tree n created by lowdown_doc_parse(3) or lowdown_diff(3)
     using the debugging renderer arg as returned by lowdown_tree_new(3).  The
     output is written into out, which must be initialised and freed by	the
     caller.

     The mq variable is	ignored.

     The output	consists of an UTF-8 tree.  The	format is not standardised and
     subject to	change.

EXAMPLES
     The following assumes the the string buf of length	bsz consists of	Mark-
     down content.

	   struct lowdown_buf *out;
	   struct lowdown_doc *doc;
	   void	*rndr;
	   struct lowdown_node *n;

	   if ((doc = lowdown_doc_new(NULL)) ==	NULL)
		   err(1, NULL);
	   if ((n = lowdown_doc_parse(doc, NULL, buf, bsz)) == NULL)
		   err(1, NULL);
	   lowdown_doc_free(doc);

	   if ((out = lowdown_buf_new(256)) == NULL)
		   err(1, NULL);
	   if ((rndr = lowdown_tree_new(NULL)) == NULL)
		   err(1, NULL);
	   lowdown_tree_rndr(out, NULL,	rndr, n);
	   lowdown_tree_free(rndr);
	   lowdown_node_free(n);

	   fwrite(out->data, 1,	out->size, stdout);
	   lowdown_buf_free(out);
