NAME

     lowdown_gemini_new — allocate a Markdown gemini renderer

LIBRARY

     library “liblowdown”

SYNOPSIS

     #include <sys/queue.h>
     #include <stdio.h>
     #include <lowdown.h>

     void *
     lowdown_gemini_new(const struct lowdown_opts *opts);

DESCRIPTION

     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).

RETURN VALUES

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

EXAMPLES

     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);
