从 Ruby 中的字符串修剪空白换行符 [英] Trim blank newlines from string in Ruby

问题描述

我有一串四行空行，总共八行，如下所示:

I have a string of four blank lines which all up makes eight lines in total in the following:

str = "aaa\n\n\nbbb\n\nccc\ddd\n" 

我想在一行中全部归还.输出应该是这样的:

I want to return this all in one line. The output should be like this on a single line:

aaabbbcccddd

我使用了各种修剪函数来获取输出，但仍然失败.

I used various trim functions to get the output but still I am failing.

这里我必须使用什么方法?

What method do I have to use here?

推荐答案

Ruby(稍微少一点 Perl 风格)方式:

The Ruby (and slightly less Perl-ish) way:

new_str = str.delete "\n"

...或者如果您想就地进行:

...or if you want to do it in-place:

str.delete! "\n"
