ruby - 一个基本的“助手”程序没有按预期工作

Question

我正在制作一个基本的“帮手”程序。无论如何，这是代码：

def sayHelp()

    puts "------------List of help and commands-------------" 
    puts "Help-- Shows a list of commands."
    puts "Start [PROGRAM] (PROGRAM ARGS)-- Starts the specified program." 
    return true
end    

version = "1.0"
ccommand = ""

puts "Welcome to RubyBot " + version + "."
puts "------------------------------------"
sleep(3)
system "clear" or system "cls"
puts "Enter \"help\" for a list of commands."


puts "Please enter a command: "
ccommand = gets


if ccommand == "help"
    sayHelp()
else
    puts "Not right bro"
end

我继续运行它并输入帮助，但它只是Not right bro对我不利。我做错了什么？

Answer 1

ccommand = gets

返回的字符串gets有一个尾随的换行符，删除它，它将起作用：

ccommand = gets.chomp
