ruby-on-rails - 在 ruby​​ 中用另一个数组中的字符串替换一个数组中的字符串

Question

类似于Ruby/Rails working with gsub and arrays .

• 我有两个数组，“errors”和“human_readable”。

• 我想通读一个名为“logins.log”的文件替换error[x] 与 human_readable[x]

• 我不关心输出到哪里，stdout 没问题。

  errors = ["0xC0000064", "0xC000006A", "0xC0000071", "0xC0000072", "0xC0000234"]human_readable =  ["Unknown User", "Bad Password", "Expired Password", "Account Disabled", "Account Locked"] file = ["logins.log"]file= File.read()errors.each 

  迷路了……

对不起，我知道这是一个愚蠢的问题，我正在尝试，但我在迭代中陷入困境。

什么对我有用(我确定其他答案有效，但这对我来说更容易理解)

 #Create the arrays
 errors = ["0xC0000064", "0xC000006A", "0xC0000071", "0xC0000072", "0xC0000234"]
 human_readable =  ["Unknown User", "Bad Password", "Expired Password", "Account Disabled",  "Account Locked"]<p></p>

<p>#Create hash from arrays
 zipped_hash = Hash[errors.zip(human_readable)]</p>

<p>#Open file and relace the errors with their counterparts
 new_file_content = File.read("login.log").gsub(Regexp.new(errors.join("|")), zipped_hash)</p>

#Dump output to stdout
 puts new_file_content

这太棒了，将成为很多东西的模板，非常感谢。

Answer 1

errors = ["0xC0000064", "0xC000006A", "0xC0000071", "0xC0000072", "0xC0000234"]
human_readable =  ["Unknown User", "Bad Password", "Expired Password", "Account Disabled", "Account Locked"]

zipped_hash = Hash[errors.zip(human_readable)]
#=> {"0xC0000064"=>"Unknown User", "0xC000006A"=>"Bad Password", "0xC0000071"=>"Expired Password", "0xC0000072"=>"Account Disabled", "0xC0000234"=>"Account Locked"}

new_file_content = File.read("logins.log").gsub(/\w/) do |word|
  errors.include?(word) ? zipped_hash[word] : word
end

or

new_file_content = File.read("logins.log").gsub(Regexp.new(errors.join("|")), zipped_hash)

puts new_file_content
