I'm have irb 1.4.1 (2021-12-25) on Windows 10 and Ubuntu 16.04. On Windows, When I type in irb 1+2, on Windows I get # => 3, but on Ubuntu I get => 3.
For me this is not a trivial matter, because I generate hundreds of examples for ruby-lang.org, using irb on both systems; I need the output to be the same, so that the examples are consistent.
Thanks for any help.
I've found irb conf.return format, which is different on the two systems. To set in irb, conf.return_format = "# => %s\n".
