LOWDOWN_GEMINI_RNDR(3)	    Library Functions Manual	LOWDOWN_GEMINI_RNDR(3)

NAME
       lowdown_gemini_rndr -- render Markdown into gemini

LIBRARY
       library "liblowdown"

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

       int
       lowdown_gemini_rndr(struct lowdown_buf *out,		    void *arg,
	   const struct	lowdown_node *n);

DESCRIPTION
       Renders	a   node   tree	  n   created	by   lowdown_doc_parse(3)   or
       lowdown_diff(3)	 using	 the   gemini  renderer	 arg  as  returned  by
       lowdown_gemini_new(3).  The output is written into out, which  must  be
       initialised and freed by	the caller.

       The  caller is expected to have invoked setlocale(3) to a "UTF-8" char-
       acter encoding prior to using this function, otherwise UTF-8  sequences
       will  not  be  properly recognised.  This is used when formatting table
       column widths.

RETURN VALUES
       Returns zero on failure to allocate memory, non-zero on success.

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);
