ansi-escape

I am attempting to get watchr running tests automatically as files change, and got most of what I need working except for the fact that all ANSI colours from RSpec are being disregarded. The offending code is as follows: stdin, stdout, stderr = Open3.popen3(cmd) stdout.each_line do |line| last_output = line puts line end When cmd is equal to something like rspec spec/**/*.rb then the above code runs RSpec fine except that all output is in monochrome.

This is a similar question to this one . I would like to convert ANSI escape sequences, especially for color, into HTML. However, I would like to accomplish this using PHP. Are there any libraries or example code out there that do this? If not, anything that can get me part way to a custom solution? I don't know of any such library in PHP. But if you have a consistent input with limited colors, you can accomplish it using a simple str_replace() : $dictionary = array( 'ESC[01;34' => '<span style="color:blue">', 'ESC[01;31' => '<span style="color:red">', 'ESC[00m' => '</span>' , ); $htmlString =
