LOWDOWN_TREE_RNDR(3)

NAME
lowdown_tree_rndr - render Markdown into debugging output

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_doc_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 Markdown 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);
