Comment on Email validation using ruby by Randal L Schwartz

As usual, every SINGLE email regex matcher here has FAILED to read RFC822. As with all the other versions, THIS REGEX IS WRONG. DO NOT USE THIS REGEX. DO NOT. AND PLEASE STOP POSTING BROKEN REGEX TO MATCH EMAIL HERE. {sigh}

%r{^(?:[_a-z0-9-]+)(\.[_a-z0-9-]+)*@([a-z0-9-]+)(\.[a-zA-Z0-9\-\.]+)*(\.[a-z]{2,4})$}i

this is the most appropriate one… with all the validations including the domain extensions…

Comment on Renaming files using ruby! by Pink Chocobo

Here is a variation - it will ask what you want as a prefix (in my case, renaming music files)

#/Users/kriplean/desktop/ruby/renamev2.rb

def rename_files_in_directory(dir, add_this_text)
files = Dir.entries(dir)
files.each do |filename|
next if filename == “.” or filename == “..”
oldFile = dir + “/” + filename
newFile = dir + “/” + add_this_text + filename
puts add_this_text + filename
File.rename(oldFile, newFile)
end
end

dir = “/Users/myusername/desktop/files”
puts “Type the Artist Name:”
add_this_text = gets.chomp
rename_files_in_directory(dir, add_this_text)

users_hash[key] = value

Why not this method?

Comment on Ruby hash merge (Add element to Ruby hash) by Hamza Khan-Cheema

Hi,

Thanks, for this,

You may also want to mention that if there is a duplicate key in the new hash, it will overwrite the original hash.

So if I did this on the original hash:

users_hash.merge(”tom” => “changed_password”)

It would change the original hash , thus changing tom’s password to be ‘changed_password’.

you can just do:

render :controller => ‘controller_name’, :action => ‘action_name’

should do the trick!
