lowdown_latex_new
(const struct
lowdown_opts *opts);
Allocates an LaTeX 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_latex_rndr(3) and must be freed
with lowdown_latex_free(3).
The bits recognised in opts->oflags are
LOWDOWN_LATEX_NUMBERED
,
LOWDOWN_LATEX_SKIP_HTML
, and
LOWDOWN_STANDALONE
.
Returns a pointer to the renderer or NULL
on memory failure. The returned pointer must be freed with
lowdown_latex_free(3).
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_latex_new(NULL)) == NULL) err(1, NULL); if (!lowdown_latex_rndr(out, NULL, rndr, n)) err(1, NULL); fwrite(out->data, 1, out->size, stdout); lowdown_latex_free(rndr); lowdown_buf_free(out); lowdown_node_free(n); lowdown_doc_free(doc);
