Ruby – String split() Method with Examples

split is a String class method in Ruby which is used to split the given string into an array of substrings based on a pattern specified.

Here the pattern can be a Regular Expression or a string. If pattern is a Regular Expression or a string, str is divided where the pattern matches.

Syntax:

arr = str.split(pattern, limit) public

Parameters: arr is the list, str is the string, pattern is the either string or regExp, and limit is the maximum entries into the array.

Returns: Array of strings based on the parameters.

Example 1:

# Ruby program to demonstrate split method

# Split without parameters
# Here the pattern is a
# single whitespace
myArray = "Geeks For Geeks".split
puts myArray

Output:

Geeks
For
Geeks

Example 2:

# Ruby program to demonstrate split method

# Here pattern is a regular expression
# limit value is 2
# / / is one white space
myArray = "Geeks For Geeks".split(/ /, 2)
puts myArray

Output:

Geeks
For Geeks

Example 3:

# Ruby program to demonstrate split method

# Here the pattern is a regular expression
# limit value is -1
# if the limit is negative there is no
# limit to the number of fields returned,
# and trailing null fields are not
# suppressed.
myArray = "geeks geeks".split('s', -1)
puts myArray

Output:

geek
 geek
