At least for me it was more than one line of C code to add it and it was not a
trivial task.
I added the following function:
void kibitzprintpv(void)
{
if (kibitzing)
{
if (computer)
printf("tellics kibitz ");
else
printf("tellics whisper ");
if (hply<2)
printf("hello from Movei ");
printspecialpv(k,x);
}
}
I also added the function printspecialpv(k,x)
k is the depth and x is the score and I needed to define them as global
varaible(they were local varaible because movei clear it's hash tables between
move and does not remember scores).
I needed to define the function printspecialpv.
The reason is that movei does not print details like nodes per second under
winboard and print the time not in seconds but in milliseconds.
I have printpv to printpv under winboard in a similiar way that tscp does it but
I saw that other people print pv in a better way for ICC so I decided to use a
function prints pv in a different way.
My function printspecialpv does not work under winboard and only after some
hours of trying to something that will work both under winboard and under ICC I
thought about the idea to use a special fuinction for ICC.
Here are my 2 functions
void printspecialpv(int k,int x)
{
int j;
float ti;
if (UseBook==0)
{
printf("%6.2f",(float)x/100);
printf("/");
printf("%d",k);
ti=(float)(get_ms() - start_time)/1000;
if (ti>0)
printf(" time= %6.2f nps= %6.0f",ti, nodes/ti);
for (j = 0; j < pv_length[0]; ++j)
printf(" %s", move_str(pv[0][j].b));
printf("\n");
}
else
printf("book\n");
fflush(stdout);
}
void printpv(int k,int x)
{
int j;
printf(" %d %d %d %d",k, x, (get_ms() - start_time) / 10, nodes);
for (j = 0; j < pv_length[0]; ++j)
printf(" %s", move_str(pv[0][j].b));
printf("\n");
fflush(stdout);
}
