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
$dictionary = array( 'ESC[01;34' => '<span style="color:blue">', 'ESC[01;31' => '<span style="color:red">', 'ESC[00m' => '</span>' , ); $htmlString = str_replace(array_keys($dictionary), $dictionary, $shellString);
The str_replace solution wouldn’t work in cases where colors are “nested”, because in ANSI color codes, one ESC[0m reset is all that’s needed to reset all attributes. While in HTML, you need the exact number of SPAN closing tags.
A workaround that works the “nested” use case is below:
// Ugly hack to process the color codes // We need something like Perl's HTML::FromANSI // http://search.cpan.org/perldoc?HTML%3A%3AFromANSI // but for PHP // http://ansilove.sourceforge.net/ only converts to image :( // Technique below is from: // http://stackoverflow.com/questions/1375683/converting-ansi-escape-sequences-to-html-using-php/2233231 $output = preg_replace("/\x1B\[31;40m(.*?)(\x1B\[0m)/", '<span style="color: red">$1</span>$2', $output); $output = preg_replace("/\x1B\[1m(.*?)(\x1B\[0m)/", '<b>$1</b>$2', $output); $output = preg_replace("/\x1B\[0m/", '', $output);
(taken from my Drush Terminal issue here: http://drupal.org/node/709742 )
I’m also looking for the PHP library to do this easily.
P.S. If you want to convert ANSI escape sequences to PNG/image, you can use AnsiLove.
There are library now: ansi-to-html
And very easy to use:
$converter = new AnsiToHtmlConverter(); $html = $converter->convert($ansi);
