Nimrod Beginner - Fizzbuzz - 編譯並運行

我試着編寫並運行我的第一個nimrod程序fizzbuzz。Nimrod Beginner - Fizzbuzz - 編譯並運行

Nimrod是從git安裝的，版本是。

[sayth nimrod]$ nimrod --version 
Nimrod Compiler Version 0.9.4 (2014-04-28) [Linux: amd64] 
Copyright (c) 2006-2014 by Andreas Rumpf

因此，這裏是一個fizzbuzz

proc fizzBuzz(x, y: int) = 
     for i in x .. y: 
       if i mod 15 == 0: 
         echo("FizzBuzz") 
       elif i mod 3 == 0: 
         echo("Fizz") 
       elif i mod 5 == 0: 
         echo("Buzz") 
       else: 
         echo(i)

我編譯爲C（有沒有更好的選擇嗎？）和它似乎挺合我意。

[sayth nimrod]$ nimrod c fizzbuzz.nim 
config/nimrod.cfg(37, 2) Hint: added path: '/home/sayth/.babel/pkgs/' [Path] 
Hint: used config file '/home/sayth/Nimrod/config/nimrod.cfg' [Conf]

Hint: fizzbuzz [Processing] 
fizzbuzz.nim(1, 5) Hint: 'fizzbuzz.fizzBuzz(x: int, y: int)' is declared but not used [XDeclaredButNotUsed]

Hint: operation successful (8181 lines compiled; 1.065 sec total; 13.138MB) [SuccessX]

但運行它不產生輸出。有什麼我做錯了嗎？

[sayth nimrod]$ ./fizzbuzz 
[sayth nimrod]$

你只是忘了叫它。注意編譯器提示：

fizzbuzz.nim(1, 5) Hint: 'fizzbuzz.fizzBuzz(x: int, y: int)' is declared but not used [XDeclaredButNotUsed]

沒有，你最好的選擇是編譯到C有可能在未來的LLVM後端，但普遍的看法是，它是更多的麻煩比它的價值。中級C輸出更具可移植性（gcc可以運行在比LLVM更多的平臺上），您可以選擇最適合您的代碼的編譯器。
