Hm. I wrote test code
--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);
}
AG_BindUint32(agConfig, "Value", &value);
fprintf(stdout, "Value = %i\n", AG_GetUint32(agConfig, "Value"));
if (!AG_GetBool(agConfig, "cel.flags.init")){
value = 1;
fprintf(stdout, "Looks it run first! set 'Value' to %i\n",
value);
}
value++;
AG_SetBool(agConfig, "cel.flags.init", 1);
AG_ObjectSave(agConfig);
AG_ConfigSave(); // to be sure ,)
AG_Destroy();
return (0);
}
--8<---------------cut here---------------end--------------->8---
Result:
--8<---------------cut here---------------start------------->8---
%rm -r ~/.ag-bind-test/
%./loader
Value = 0
Looks it run first! set 'Value' to 1
%./loader # must be 1
Value = 0
%grep cel ~/.ag-bind-test/config.AG_Config # is cel.flags.init saved
(affcause yes)
Binary file /home/osprey/.ag-bind-test/config.AG_Config matches
%grep Value ~/.ag-bind-test/config.AG_Config # check for 'Value' in config
% # damn
--8<---------------cut here---------------end--------------->8---
expected:
%./loader
Value = 0
Looks it run first! set 'value' to 1
%./loader
Value = 1
=), but...
In any case binding shoud be good future of agar.
