reproduce process here
But, it works before introduce the colorful feature of IRB, and work still quite well with Pry.
we can fix this issue use following workaround.
But, that will make IRB lose colorful.
So, i thought somethings break changes introduced since new IRB released.
following is a screenshot, check how looks here
I thought this issue should possible be fixed, so, i do some hack myself.
if change https://github.com/ruby/ruby/blob/v3_1_2/lib/irb/context.rb#L56 line from
@use_colorize = IRB.conf[:USE_COLORIZE] into @use_colorize = false, it works perfect,
that is, irb is colorful, and looksee output is colorful too.
But, above source code was moved on newest master, I am not sure if this issue was fixed in ruby 3.2.0 too.
because install ruby-head or 3.2.0-preview both failed on my laptop use RVM.
so just ask here.
thank you.
