Split on different newlines

Question

Right now I\'m doing a split on a string and assuming that the newline from the user is \\r\\n like so:

string.split(/\\r\\n/)
<         


        

Answer 1

Ruby has the methods String#each_line and String#lines

returns an enum: http://www.ruby-doc.org/core-1.9.3/String.html#method-i-each_line

returns an array: http://www.ruby-doc.org/core-2.1.2/String.html#method-i-lines

I didn't test it against your scenario but I bet it will work better than manually choosing the newline chars.

Answer 2

The alternation operator in Ruby Regexp is the same as in standard regular expressions: |

So, the obvious solution would be

/\r\n|\n/

which is the same as

/\r?\n/

i.e. an optional \r followed by a mandatory \n.
