Description
#!/usr/bin/env ruby
require 'readline'
prompt = "asdf: "
default = "true"
Readline.pre_input_hook = -> do
Readline.insert_text "#{default}"
Readline.redisplay
Readline.pre_input_hook = nil
end
Readline.readline(prompt)
prompt: trueprompt:
the cursor sits at the right place (behind the 'e' in 'true'). inserting a backslash causes the line to be cleared and fixes the display.
expected display, correct in previous versions:
prompt: true
