Question

与Ruby/Rails working with gsub and arrays类似。

我有两个数组，“errors”和“human_readable”。
我想通读一个名为“logins.log”的文件替换带有human_readable [x]

我不关心输出在哪里，stdout很好。

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

...丢失

对不起，我知道这是一个愚蠢的问题，我正在尝试，但我在迭代中纠缠不清。

什么对我有用（我确信其他答案是有效的，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"]

#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

这很棒，并且会成为很多东西的模板，感谢百万。

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

用ruby中的另一个数组替换另一个数组中的字符串
