void *
lowdown_gemini_new(const struct lowdown_opts *opts);

Allocates a Gemini renderer using opts->oflags, or zero if opts is NULL. The returned pointer may be used with multiple invocations of lowdown_gemini_rndr(3) and must be freed with lowdown_gemini_free(3).

The bits recognised in opts->oflags are LOWDOWN_GEMINI_LINK_IN, LOWDOWN_GEMINI_LINK_END, LOWDOWN_GEMINI_LINK_NOREF, LOWDOWN_GEMINI_LINK_ROMAN, LOWDOWN_GEMINI_METADATA, and LOWDOWN_STANDALONE. These are documented in lowdown(3).

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

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

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

if (setlocale(LC_CTYPE, "en_US.UTF-8") == NULL)
	err(1, NULL);
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_gemini_new(NULL)) == NULL)
	err(1, NULL);
if (!lowdown_gemini_rndr(out, rndr, n))
	err(1, NULL);

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

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