阅读行，改变＆amp;删除Ruby

Question

我有一个我想在Ruby中操作的文件。我相信它应该很容易但是找不到它，因为我是新手。在这些线上我有一些数据，如;

Bassmaster Boats Inc#Bassmaster Boats Inc                    
Basstream#Basstream                    
Bat Inflatable Boats#Bat Inflatable Boats                    
Bavaria Motoryachts#Bavaria Motoryachts                    
Bavaria Sailing Yachts#Bavaria Sailing Yachts                    
Bay Craft Inc#Bay Craft Inc                    
Bay Hawk Industries Inc#Bay Hawk Industries Inc                    
Bay Quest#Bay Quest                    
Bay Warrior Boats#Bay Warrior Boats                    
Bay Water Boats#Bay Water Boats                    
Bayfield Boat Yard Ltd#Bayfield Boat Yard Ltd                    
Bayliner Marine Corp#Bayliner Marine Corp                    
Baymaster Boats Inc#Baymaster Boats Inc                    
Baymaster by Dargel#Baymaster by Dargel                    
Bayon#Bayon                    
Bayrunner#Bayrunner            

我想要做的是找到单词之间的空格 - 如果有的话 - 并放置+并删除#符号后的任何内容。所以看起来应该是这样的;

Bassmaster+Boats+Inc             
Basstream
Bat+Inflatable+Boats
Bavaria+Motoryachts
Bavaria+Sailing+Yachts
.....
.....
.....

提前谢谢

Answer 1

正则表达式

我建议您使用regular expression查找匹配项。

1. 包含＃符号后的字符串 #.*

2. 空间 或\s（也与标签字符匹配）

用Ruby替换匹配

您可以将匹配的字符串替换为gsub!。

s.gsub!(/#.*/, '').gsub!(/ /, '+')

Answer 2

执行以下操作：

File.open("another/file", "w") do |file|
  File.foreach("filename") do |line|
    line[/(#.*)/] = ""
    file.puts line.gsub(\s+\, "+")
  end
end
