Ruby 'gets' 适用于多行 [英] Ruby 'gets' that works over multiple lines

问题描述

使用 IRB，我想输入一个多行字符串以从中去除某些字符.gets"只允许一行 - 多行是否有类似的功能.

Using the IRB, I want to enter a multiple line string in order to strip certain characters from it. "gets" only allows a single line - is there a similar function for multiple lines.

ASCII_project.rb(main):002:0* puts = "What's the text you want to strip?"
=> "What's the text you want to strip?"
ASCII_project.rb(main):003:0> str = gets

我现在想粘贴一段文本 - 因为新行它不起作用.这就是为什么我想收集多行

I now want to paste in a section of text - because of the new lines it doesn't function. This is why I want to collect over multiple lines

这是代码

# encoding: CP850
puts = "What's the text you want to strip?"
str = gets
str.gsub!(/\P{ASCII}/, '')
puts str

推荐答案

您可以通过以下方式进行，

You can do this in following way,

$/ = "END"  
user_input = STDIN.gets
puts user_input

当您认为输入完成时，请确保输入 END 关键字，

make sure to type END keyword when you think the input is finished,

同样，这只适用于实际的解释器，而不适用于 irb.

As well this will only work with actual interpreter not irb.
