LOWDOWN_NROFF_RNDR(3) Library Functions Manual LOWDOWN_NROFF_RNDR(3) NAME lowdown_nroff_rndr -- render Markdown into roff LIBRARY library "liblowdown" SYNOPSIS #include <sys/queue.h> #include <stdio.h> #include <lowdown.h> int lowdown_nroff_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 roff renderer arg as returned by lowdown_nroff_new(3). The output is written into out, which must be initialised and freed by the caller. The output consists of roff output using the ms or man macro packages. RETURN VALUES Returns zero on failure to allocate memory, non-zero on success. EXAMPLES The following parses b of length bsz and outputs in groff_ms(7) format. 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, b, bsz, NULL)) == NULL) err(1, NULL); if ((out = lowdown_buf_new(256)) == NULL) err(1, NULL); if ((rndr = lowdown_nroff_new(NULL)) == NULL) err(1, NULL); if (!lowdown_nroff_rndr(out, rndr, n)) err(1, NULL); fwrite(out->data, 1, out->size, stdout); lowdown_nroff_free(rndr); lowdown_buf_free(out); lowdown_node_free(n); lowdown_doc_free(doc); SEE ALSO lowdown(3), lowdown_nroff_free(3), lowdown_nroff_new(3) This uses both the original troff man macros for Version 7 AT&T UNIX, defined in man(7), and the man-ext groff extensions. Both are imple- mented in mandoc. The troff ms macros are defined in groff_ms(7), with the mspdf groff extensions described in "Portable Document Format Publishing with GNU Troff" by Keith Marshall. Neither are implemented in mandoc. FreeBSD Ports 14.quarterly $Mdocdate$ LOWDOWN_NROFF_RNDR(3)
