Bug #18768: Inconsistent behavior of IO, StringIO and String each_line methods when return paragraph and chomp: true passed
https://bugs.ruby-lang.org/issues/18768
* Author: andrykonchin (Andrew Konchin)
* Status: Open
* Priority: Normal
* ruby -v: 3.0.3
* Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
In IO, StringIO and String methods that return lines (e.g. `each`, `each_line`, `gets`, `readline`, `readlines`) behave in a different way when the following parameters are passed
- separator is `""` and
- `chomp` is `true`.
They truncate the new line characters between paragraphs and the trailing one differently:
```ruby
"a\n\nb\n\nc\n".each_line("", chomp: true).to_a
#=> ["a\n", "b\n", "c\n"]
StringIO.new("a\n\nb\n\nc\n").each_line("", chomp: true).to_a
#=> ["a\n", "b\n", "c"]
IO.readlines('chomp.txt', "", chomp: true)
#=> ["a", "b", "c\n"]
```
The text file content is the same:
```ruby
File.read('chomp.txt')
#=> "a\n\nb\n\nc\n"
```
Expected behavior - they return the same result.
