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.
IRB.conf[:USE_COLORIZE] = false
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.
