I want to continue topic. I'd like to see some this future its
great, you don't need to catch exit hook of app to save variables, etc.
Offcause variable not saved after bind* - agVariableTypes[]->typeTgt=-1
for poiner, so here simple patch for Uint32 only:

It make possible to save pointer as uint32 to file and load him,
but (maybe) need some api to setup variable when binding i.e instead of
#v+
value = AG_GetUint32(agConfig, "Value");
// we wish set prev. saved value
AG_BindUint32(agConfig, "Value", &value);
#v-
need some AG_BindAndSet or other, nut it no so important.
Some test:
--8<---------------cut here---------------start------------->8---
Uint8 value = 0;
int
main(int argc, char *argv[])
{
if (AG_InitCore("ag-bind-test", 0) == -1) {
fprintf(stderr, "%s\n", AG_GetError());
return (1);
}
fprintf(stdout, "cheking for 'Value' (AG_GetUint32) %u\n",
AG_GetUint32(agConfig, "Value"));
value = AG_GetUint32(agConfig, "Value");
AG_BindUint32(agConfig, "Value", &value);
if (!AG_GetBool(agConfig, "not.first.run")){
value = 1;
fprintf(stdout, "Looks it run first! set 'Value' to %i\n",
value);
}
value++; // inc binded variable
fprintf(stdout, "AG_BindUint32, Value = %i\n", AG_GetUint32(agConfig,
"Value"));
AG_SetBool(agConfig, "not.first.run", 1);
AG_ConfigSave();
AG_Destroy();
return (0);
--8<---------------cut here---------------end--------------->8---
and output:
#v+
%rm -r ~/.ag-bind-test/*
%./loader
cheking for 'Value' (AG_GetUint32) 0
Looks it run first! set 'Value' to 1
after AG_BindUint32, Value = 2
%./loader
cheking for 'Value' (AG_GetUint32) 2
after AG_BindUint32, Value = 3
#v-
