Just a small tip for those people, who use following code style:
if( cond ) {
body
} else {
body
}
I've found it very convenient to "attach" unittest block to my function declatarions in a same way:
private int find_pos_divisor( int first, int second ) {
int temp;
while( second ) {
temp = second;
second = first % second;
first = temp;
}
return abs( first );
} unittest {
assert( find_pos_divisor ( 10, 20 ) == 10 );
assert( find_pos_divisor ( 10, 0 ) == 10 );
assert( find_pos_divisor ( 9, 6 ) == 3 );
assert( find_pos_divisor ( 10, 3 ) == 1 );
}
Looks as a natural extension to the declaration, and helps to keep all related code in one place. Did anyone found out any more convenient D-specific conventions?
