DESCRIPTION

Allocates an HTML5 renderer using opts->flags, or zero if opts is NULL. This field is documented in lowdown(3). The returned pointer may be used with multiple invocations of lowdown_html_rndr(3) and must be freed with lowdown_html_free(3).

The bits recognised in opts->oflags are LOWDOWN_HTML_OWASP, LOWDOWN_HTML_NUM_ENT, LOWDOWN_HTML_HEAD_IDS, LOWDOWN_HTML_HARD_WRAP, LOWDOWN_HTML_SKIP_HTML, LOWDOWN_HTML_ESCAPE, LOWDOWN_HTML_CALLOUT_MDN, LOWDOWN_HTML_CALLOUT_GFM, and LOWDOWN_STANDALONE.

RETURN VALUES

Returns a pointer to the renderer or NULL on memory failure. The returned pointer must be freed with lowdown_html_free(3).

EXAMPLES

The following parses b of length bsz and outputs in HTML format.

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 ((rndr = lowdown_html_new(NULL)) == NULL)

err(1, NULL);

if (!lowdown_html_rndr(out, 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);
