Issue #14257 has been updated by shevegen (Robert A. Heiler).


I wanted to have a look but to my surprise, the documentation at:

https://ruby-doc.org/core-2.5.0/String.html#method-i-lines

does not seem to indicate more than one agument to this method?

Either way, could someone perhaps add a few examples to this
method, on the documentation, perhaps also including the
lines(' ', chomp: true) variant? Because as it presently is,
I can't seem to find the chomp: true part. Perhaps it was added
only somewhat recently.

----------------------------------------
Bug #14257: the chomp option removes newlines in additon to the provided separator for String#each_line and String#lines

----------------------------------------
I'm not entirely sure this is a bug but I had a hard time finding anything that indicated that the change was on purpose.

The `chomp` option would remove the provided separator from each line. Now it does that and it also removes newlines.

2.4

~~~ ruby
> "a b c d\n".lines(' ', chomp: true)
=> ["a", "b", "c", "d\n"]
~~~

2.5

~~~ ruby
> "a b c d\n".lines(' ', chomp: true)
=> ["a", "b", "c", "d"]
~~~
