Letteralmente (tratto da “The Practice of Programming”, con Rob Pike, Addison-Wesley Professional, 1999)
As personal choice, we tend not to use debuggers beyond getting a stack trace or the value of a variable or two.
One reason is that it is easy to get lost in details of complicated data structures and control flow; we find stepping through a program less productive than thinking harder and adding output statements and self-checking code at critical places.
Clicking over statements takes longer than scanning the output of judiciously-placed displays. It takes less time to decide where to put print statements than to single-step to the critical section of code, even assuming we know where that is.
More important, debugging statements stay with the program; debugging sessions are transient.
Io, da quando programmo per il web, uso questa modalità: sinceramente, pensavo di essere un troglodita ma sono felice di vedere che sono in buona compagnia!
