Felix now has a tiny bare bones binding to sqlite3.
No attempt is made to configure it for Windows..
The binding is mainly there to act as a driver for an experiment
making SQL a Domain Specific Sublanguage of Felix.
A couple of other small changes have been made, to the handling
of pointers. Expect some pain in this area.
Note for example some of the test code:
//////////////////
fun subscript: & &char * int -> &char = "$1[$2]";
cfun eh(void *data, int ncols, char * *values, char* *names):int =
{
int i = 0;
whilst i<ncols do
print$ str names.[i] + "=" + str values.[i];
if i<ncols-1 do print ", "; done;
++i;
done;
println "";
return 0;
}
void run(struct sqlite3_db_t db) {
///////////////////////
and you will see the new "C" syntax in action. You can't teach
an old skaller new tricks ..
Notice that
char * *
and
& &char
and
&ptr[char]
and
&charp
are all the same type now. You have to put ugly spaces in
the * * because ** is Fortran exponential operator.
You have to put ugly spaces in & & because && is
also another operator .. ;(
The callback type is:
typedef sqlite3_exec_callback_t =
address * int * ptr[charp] * ptr[charp] --> int;
which this function has:
cfun eh(void *data, int ncols, char * *values, char* *names):int =
Ouch. I have to use 'cfun' here not a C declaration because
the callback really has to be a C function pointer.
[See earlier post]
This is all rather messy .. ;(
