It will remove nothing at all from the original string and split on every character.
Ruby string each char.
If the delimiter passed to string split is a zero length string or regular expression then string split will act a bit differently.
How can i loop through each character in a ruby string and perform some operation on each character.
But the each char method is often a better choice for string.
String objects may be created using new or as literals.
Sometimes it s useful to work with the individual characters of a string.
We could use a for loop with logical branches but iterators can also be used.
Suppose we want to iterate over the characters or lines in a string.
To be clear this code will not work in ruby 1 8 6.
A string object holds and manipulates an arbitrary sequence of bytes typically representing characters.
Sometimes given a string i need to go over it character by character.
This essentially turns the string into an array of equal length containing only one character strings one for each character in the string.
Each char instance method string each char each char cstr block self each char enumerator.
One way to do that is to use the each char method.
It can easily be done after using split to cut up the sting or by using the each char method.

A string contains text data.
If you wish to use a for loop over a string this is possible in ruby.

Ruby strings use strings.
Because of aliasing issues users of strings should be aware of the methods that modify the contents of a string object.
I m currently using ruby 1 8 6 and you can use the ruby each char method if you ll first require the jcode module.
Then you can use each on this array to iterate.
Create literals manipulate strings and use each char and each line.
