NAME

       lowdown_tree_rndr — render Markdown into debugging output

LIBRARY

       library “liblowdown”

SYNOPSIS

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

       int
       lowdown_tree_rndr(struct lowdown_buf *out, const struct lowdown_node *n);

DESCRIPTION

       Renders  a  node  tree  n created by lowdown_doc_parse(3) or lowdown_diff(3).  The output is written into
       out, which must be initialised and freed by the caller.

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

       Unlike other renderers, lowdown_tree_rndr() accepts no options and thus has no context.

RETURN VALUES

       Returns zero on failure to allocate memory, non-zero on success.

EXAMPLES

       The following parses b of length bsz and outputs the parse tree.

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

             if ((doc = lowdown_doc_new(NULL)) == NULL)
                     err(1, NULL);
             if ((n = lowdown_doc_parse(doc, NULL, b, bsz, NULL)) == NULL)
                     err(1, NULL);
             if ((out = lowdown_buf_new(256)) == NULL)
                     err(1, NULL);
             if (!lowdown_tree_rndr(out, n))
                     err(1, NULL);

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

             lowdown_buf_free(out);
             lowdown_node_free(n);
             lowdown_doc_free(doc);
