I’ve tried the below
puts “Enter words to redact (ex: word1, word2):”
redact = gets.chomp.downcase!
redacted = redact.split(", ")
but I’m getting an error in the console: undefined method `split’ for nil:NilClass
Why is that, can’t my delimited for the .split be a comma followed by a space? Or am I missing something?
The bang! method works in-place. It should not be assigned owing to the behavior. If the text has no uppercase characters the assigned value will be Nil. Suggest remove the !.
puts “Input you text:”
text = gets.chomp.downcase!
puts “Input word for redact:”
redact = gets.chomp.downcase!
new_string = “”
words = text.split(" ")
words.each { |word|
if redact.include? word
new_string << "REDACTED "
else
new_string << word + " "
end
}
print new_string
Does you IF statment not need an else?
I tried it BTW and it works great so thanks a lot
I tried the code pictured, but it wasn’t working for me, don’t know why.
So, I went the unless route instead and it worked. Code is below:
puts “Write three words”
text = gets.chomp
words = text.downcase.split (" ")
puts “Two words to censor”
censor = gets.chomp
bad_word = censor.downcase.split (" ")
words.each do |words|
bad_word.each do |bad_word|
unless words != bad_word
words = "CENSORED "
end
end
print words + " "
end
puts "Please input sentence here :"
text = gets.chomp
redact = []
answer = ''
loop do
puts "Please input word to redact :"
redact << gets.chomp
puts "Would you like to add more words? (y/n)"
answer = gets.chomp
break unless answer == 'y' || answer == 'Y'
end
words = text.split (' ')
words2 = []
words.each do |word|
words2 << word
redact.each do |redact|
if word.downcase == redact.downcase
words2.pop
words2 << "REDACTED"
end
end
end
words2.each do |word|
print word + ' '
end
I think all extra points have been included. The words to be redacted are stored in an array which can be as long as the user wants.
puts ‘text please:’
text = gets.chomp
puts ‘words to redacted:’
redact = gets.chomp.downcase!
redacts = redact.split(’ ‘)
words = text.split(’ ')
words.each_with_index do |word, index|
if redacts.include? word.downcase
words.delete(word)
words.insert(index, “REDACTED”)
end
end
puts words.join(" ")
I had this same problem, actually. “execution expired” when I run the code that was given to us as a solution. I’m not really sure why that is and I can’t really troubleshoot as I’ve literally just started learning Ruby yesterday, honestly.
If anyone else has any suggestions, let us know!
Here is what works somewhat.
Click the “Run” button. The Run button will just keep showing like the program hasn’t run. Don’t worry about it. Click in the terminal window with your mouse. Even though the cursor won’t blink, you should immediately start typing your text. You must be quick about it. If you take too long, you will get the “execution expired” message.
In short:
Click the “Run” button
Click in the terminal window and immediately start typing. You must type your text, hit enter and then type the words to be redacted and hit enter. You must be REALLY quick about this. If you take too long, you will get the execution expired error.
puts "Enter a sentence to redact"
phrase = gets.chomp
puts "Enter words to redact"
redactable = gets.chomp
redactable.split(" ").each do |wordToRedact|
i = ""
phrase.split(" ").each do |word|
if word == wordToRedact
i += "REDACTED "
else
i += word + " "
end
end
phrase = i
end
print phrase
Hi, in this context what does redact mean?
Thanks
It means to remove from view, similar to making a photo copy of a document and then concealing sensitive or private text with a black felt marker.
puts "Input text"
text = gets.chomp
puts "Text to REDACT, separate with commas"
redact = gets.chomp.gsub(/\s+/, "")
words = text.split(" ")
redacted_words = redact.split(",")
output = ''
words.each do |word|
word_printed = false
redacted_words.each do |redact_word|
if word =~ /(?i)\b#{redact_word}\b/
output += "REDACTED" + " "
word_printed = true
end
end
if word_printed == false
output += "#{word}" + " "
end
end
puts "#{output}"
Managed to get all the bonus things working with this, pretty pleased with myself not going to lie
could you please explain it
if word =~ /(?i)\b#{redact_word}\b/
just this line is very complicated
If you haven’t read up on Regular Expressions (regex) and pattern matching, then this would be a good time to explore that topic.
string =~ regex pattern
To be fair, we should at least describe what that pattern is matching to in this example so you have some carry away information. My bad.
We’re looking for a word pattern in a string. We know there won’t be any space characters because we have specified word boundaries with the escape character, '\b'.
As far as the, (?i), that has something to do with a capturing group which I might have simply made into a greedy match. Ask me more about this when you are more aware of Regex and we might both learn something.
Realize that Regex is another language that is very strict in how it interprets the patterns we give it to match against.
I try this, amazing!!! 
, is not perfect but its working
redactor = [] # array for redact to input many values
result = "" #display result
puts "Write anything : "
text_saisie = gets.chomp
loop do # start loop for add many words to redact
puts "Word to be change ? "
redactor << gets.chomp #add value in redactor
puts "Will you enter another word ? y or n "
user_input = gets.chomp
user_input.downcase!
while (user_input.empty?) || (user_input != "y" && user_input != "n") #this loop forces the user to answer with y or n
puts "Please enter y or n only!!"
user_input = gets.chomp
user_input.downcase!
end
break if user_input == "n" # if the answer is yes the loop is restart
end
words = text_saisie.split(" ") # This separated input in the beginning of this program
words.each do |word| #iteration
if redactor.include? word #matching between the two lists
word = "REDACTED "
else
word = word + " "
end
result += word # the result is saved in result
end
print result
Line 9 looks a bit off. Should it be singular?
