xo_set_info
LIBXO(3) BSD Library Functions Manual LIBXO(3)
NAME
xo_emit -- emit formatted output based on format string and arguments
LIBRARY
library ``libxo''
SYNOPSIS
#include <libxo/xo.h>
void
xo_set_info(xo_handle_t *handle, xo_info_t *info, int count);
DESCRIPTION
HTML data can include additional information in attributes that begin with "data-". To enable this, three things must occur:
First the application must build an array of xo_info_t structures, one per tag. The array must be sorted by name, since libxo uses a binary
search to find the entry that matches names from format instructions.
The xo_info_t structure is defined in <libxo/xo.h>:
typedef struct xo_info_s {
const char *xi_name; /* Name of the element */
const char *xi_type; /* Type of field */
const char *xi_help; /* Description of field */
} xo_info_t;
Second, the application must inform libxo about this information using the xo_set_info() call. Like other libxo calls, passing NULL for the
handle tells libxo to use the default handle.
If the count is -1, libxo will count the elements of info, but there must be an empty element at the end. More typically, the number is
known to the application:
xo_info_t info[] = {
{ "in-stock", "number", "Number of items in stock" },
{ "name", "string", "Name of the item" },
{ "on-order", "number", "Number of items on order" },
{ "sku", "string", "Stock Keeping Unit" },
{ "sold", "number", "Number of items sold" },
};
int info_count = (sizeof(info) / sizeof(info[0]));
...
xo_set_info(NULL, info, info_count);
Third, the emission of info must be triggered with the XOF_INFO flag using either the xo_set_flags() function or the ``--libxo=info'' command
line argument.
The type and help values, if present, are emitted as the "data-type" and "data-help" attributes:
<div class="data" data-tag="sku" data-type="string"
data-help="Stock Keeping Unit">GRO-000-533</div>
