markdown(struct buf *ob, struct buf *ib, const struct mkd_renderer *rndr);
DESCRIPTION
The markdown() function parses the input buffer ib and renders it into the output buffer ob; rndr is a
pointer to the renderer structure.
Function pointers in struct mkd_renderer can be NULL. A null block-level callback will make the
corresponding block disappear from the output, as if the callback was an empty function. A null span-
level callback will cause the corresponding element to be treated as normal characters, copied verbatim
to the output. Moreover, span-level callbacks return an integer, which tells whether the renderer
accepts to render the item (non-zero return value) or whether it should be copied verbatim (zero return
value).
The first argument of a renderer function is always the output buffer, where the function is supposed to
write its output. The last argument of a renderer function is always a private pointer, which is opaque
member of struct mkd_renderer. libsoldout itself never does nothing with this data.
emph_chars is a zero-terminated string which contains the set of characters that trigger emphasis. In
regular markdown, emphasis is only triggered by ‘_’ and ‘*’, but in some extensions it might be useful to
add other characters to this list. The character that triggered the emphasis is then passed to emphasis,
double_emphasis and triple_emphasis function callbacks through the parameter c.
The normal_text callback should perform whatever escape is needed to have the output looking like the
input data.
libsoldout supports PHP-Markdown-like tables. It uses the following flags: MKD_CELL_ALIGN_DEFAULT,
MKD_CELL_ALIGN_LEFT, MKD_CELL_ALIGN_RIGHT, MKD_CELL_ALIGN_CENTER, MKD_CELL_ALIGN_MASK, MKD_CELL_HEAD in
these function callbacks: table_cell and table_row.
MKD_LIST_ORDERED, MKD_LI_BLOCK are used as flags in these function callbacks: list and listitem.
Types
enum mkd_autolink
type of autolink:
MKDA_NOT_AUTOLINK
used internally when it is not an autolink.
MKDA_NORMAL
normal http/https/ftp link.
MKDA_EXPLICIT_EMAIL
e-mail link with explicit mailto.
MKDA_IMPLICIT_EMAIL
e-mail link without mailto.
struct mkd_renderer
