LOWDOWN_TREE_RNDR(3) Library Functions Manual 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> int lowdown_tree_rndr(struct lowdown_buf *out, const struct lowdown_node *n, const struct lowdown_opts *opts); 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); SEE ALSO lowdown(3) FreeBSD ports 15.quarterly $Mdocdate$ LOWDOWN_TREE_RNDR(3)
