lowdown_html_rndr
(struct lowdown_buf
*out, struct lowdown_metaq *mq,
void *arg, const struct lowdown_node
*n);
Renders a node tree n created by lowdown_doc_parse(3) or lowdown_diff(3) using the HTML renderer arg as returned by lowdown_html_new(3). The output is written into out, which must be initialised and freed by the caller.
If mq is not NULL
,
it is filled with any metadata as parsed. It must be initialised and its
contents freed with lowdown_metaq_free(3).
The output consists of a UTF-8 HTML5 document.
Returns zero on failure to allocate memory, non-zero on success.
The following assumes the the string buf of length bsz consists of Markdown content.
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, buf, bsz)) == NULL) err(1, NULL); if ((out = lowdown_buf_new(256)) == NULL) err(1, NULL); if ((rndr = lowdown_html_new(NULL)) == NULL) err(1, NULL); if (!lowdown_html_rndr(out, NULL, rndr, n)) err(1, NULL); fwrite(out->data, 1, out->size, stdout); lowdown_html_free(rndr); lowdown_buf_free(out); lowdown_node_free(n); lowdown_doc_free(doc);
The referenced HTML5 standard is HTML5.2. Output is compatible with prior HTML5 standards.
