LOWDOWN_TERM_NEW(3) Library Functions Manual LOWDOWN_TERM_NEW(3)

NAME

lowdown_term_new — allocate a Markdown terminal renderer

LIBRARY

library “liblowdown”

SYNOPSIS

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

void *

lowdown_term_new(const struct lowdown_opts *opts);

DESCRIPTION

Allocates a terminal renderer using opts->cols, opts->hmargin, opts->vmargin, and opts->oflags, or 80 and all others zero, respectively, if opts is NULL. These fields are documented in lowdown(3). The returned pointer may be used with multiple invocations of lowdown_term_rndr(3) and must be freed with lowdown_term_free(3).

The bits recognised in opts->oflags are LOWDOWN_TERM_SHORTLINK, LOWDOWN_TERM_NOCOLOUR, and LOWDOWN_TERM_NOLINK.

RETURN VALUES

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

EXAMPLES

The following parses b of length bsz and outputs in ANSI terminal 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_term_new(NULL)) == NULL)

err(1, NULL);

if (!lowdown_term_rndr(out, rndr, n))

err(1, NULL);

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

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