问题描述
我永远不需要从gets获得的结尾换行符.一半的时间我忘记了chomp，这对...来说很痛苦.
I never need the ending newline I get from gets. Half of the time I forget to chomp it and it is a pain in the....
为什么在那儿?
推荐答案
类似于puts(听起来很像)，它设计为使用\n字符与线条配合使用.
Like puts (which sounds similar), it is designed to work with lines, using the \n character.
gets带有一个可选参数，用于分割"输入(或一直读取直到到达")，默认为特殊的全局变量$/，默认情况下包含\n.
gets takes an optional argument that is used for "splitting" the input (or "just reading till it arrives). It defaults to the special global variable $/, which contains a \n by default.
gets是用于读取流的非常通用的方法，并包含此分隔符.如果不这样做，部分流内容将丢失.
gets is a pretty generic method for readings streams and includes this separator. If it would not do it, parts of the stream content would be lost.
