Oops! I posted a wrong test program (in trying to reduce it as much as possible, I removed important characters). The colours should have been bounded by \001s and \002s. There is still a problem where the prompt is screwed as in the example above and I will try to distil and example of it later.
However, even with the correct escape sequence there is a problem:
require 'rb-readline'
cyan = "\001\e[0;36m\002"
reset = "\001\e[0m\002"
prompt = "#{cyan}screwy#{reset} % "
loop do
Readline.readline(prompt, true)
end
This:
hello<Enter>
[Ctrl-r]hel[Right-arrow]
Produces:
% ruby --version
ruby 1.9.2p180 (2011-02-18) [x86_64-linux]
% ruby -I lib/ examples/issue-53
screwy % hello
screwy % hello
^--- cursor is incorrectly here
This works fine with Ruby 1.8.
from rb-readline.
This still happens on 1.9.3:
% ruby --version
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]
