文件： remove-codes.php 项目： clue/term-react

// this simple example reads from STDIN, removes ALL codes and then prints to STDOUT.
// you can run this example and notice that special keys will be filtered out:
// $ php remove-codes.php
//
// you can also pipe the output of other commands into this to remove any control
// codes like this:
// $ phpunit --color=always | php remove-codes.php
