Hi!
I'm studying how to export pseudo variables.
In tm.c there is this code:
if(xl_add_extra("T_branch_idx", it_get_tm_branch_idx, 100
)!=0)
btw: what means type=100 ?
shouldn't it be
xl_add_extra("T_branch_idx", it_get_tm_branch_idx, XL_ITEM_EXTRA )
^^^^^^^^^^
or how do I export new pseudo variables?
Are there somewhere developer docs for pseudo variables? e.g.
xl_value_t members?
not very much :-)
Here is some description:
There are a set of flags which specifies the type of value, the names
are more or less suggestive.
#define XL_VAL_NULL 1
#define XL_VAL_EMPTY 2
#define XL_VAL_STR 4
#define XL_VAL_INT 8
#define XL_TYPE_INT 16
typedef struct _xl_value
{
str rs; // the string value
int ri; // the integer value
int flags; // combination of flags
} xl_value_t, *xl_value_p;
There can be combination of flags, so that both string and integer
fields are filled. If the primary type is integer the XL_TYPE_INT flag
is set as well.
For example, the pseudovariable for time in string format sets both
fields, rs is the string formatted time, ri is the timestamp and the
flags are set to XL_VAL_STR|XL_VAL_INT.
The plans are to use the flags parameter of the functions from items.c
to force the result to a certain type.
Cheers,
Daniel
