是否可以逐步完成RoR應用程序？或僅使用調試斷點進行調試？

Question

我讀過，你可以在你的RoR代碼中放一個'調試'符號，然後執行將暫停在那個點，然後你可以吐出任何東西到控制檯來查看變量的狀態等。

Is there一種通過每一行並遵循執行路徑的方式？

Answer 1

調試器本身有文檔。 n和s是您正在查找的命令。

(rdb:1) help 
ruby-debug help v0.10.3 
Type 'help <command-name>' for help on a specific command 

Available commands: 
backtrace delete enable help next quit  show trace  
break  disable eval info p  reload source undisplay 
catch  display exit irb  pp restart step up  
condition down  finish list ps save  thread var  
continue edit  frame method putl set  tmate where  

(rdb:1) help next 
n[ext][+-]?[ nnn] step over once or nnn times, 
     '+' forces to move to another line. 
     '-' is the opposite of '+' and disables the force_stepping setting. 
(rdb:1) help step 
s[tep][+-]?[ nnn] step (into methods) once or nnn times 
     '+' forces to move to another line. 
     '-' is the opposite of '+' and disables the force_stepping setting. 
(rdb:1) 

Answer 2

這個Railscast episode也有一些關於ruby-debug的提示。
