使用PTY.spawn记录脚本化进程的整个IO

Question

$watch

有没有办法记录脚本化过程的整个会话？

在此示例中，输出应类似于：

require 'pty'
require 'expect'

reader, writer, _pid = PTY.spawn('irb')

# log = StringIO.new # or maybe something else
# Attach/Tee logger to reader/writer

reader.expect(/.*> /, 1) do |line|
  puts "Line = #{line}"
  writer.puts '1+1'
end

10.times do
  reader.expect(/.*[\r\n]/, 1) { |line| puts "Line = #{line}" }
end

# puts log.string

结帐Open3。它已经内置到ruby中，让您可以查看终端中的所有流。您可能需要popen3或capture3
