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?
