用Ruby中的另一个数组替换字符串中的字符串

Question

Similar to Ruby/Rails working with gsub and arrays .

• I have two arrays, "errors" and "human_readable".

• I would like to read through a file named "logins.log" replace error[x] with human_readable[x]

• I don't care where the output goes, stdout is fine.

  \nerrors = ["0xC0000064", "0xC000006A", "0xC0000071", "0xC0000072", "0xC0000234"] \nhuman_readable = ["Unknown User", "Bad Password", "Expired Password", "Account Disabled", "Account Locked"]  \nfile = ["logins.log"] \n\nfile= File.read() \nerrors.each  \n

  lost...

I am sorry, I know this is a dumb question and I am trying but I am getting tangled up in the iteration.

What worked for me (I am sure the other answer is valid but this was easier for me to understand)

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


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

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

#Dump output to stdout puts new_file_content 

This is awesome and will become the template for a lot of stuff, thanks a million.

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
