  3. # Convert ANSI (terminal) colours and attributes to HTML
  4.  
  5. # Licence: LGPLv2
  6. # Author:
  7. #    http://www.pixelbeat.org/docs/terminal_colours/
  8. # Examples:
  9. #    ls -l --color=always | ansi2html.sh > ls.html
  10. #    git show --color | ansi2html.sh > last_change.html
  11. #    Generally one can use the `script` util to capture full terminal output.
  12. # Changes:
  13. #    V0.1, 24 Apr 2008, Initial release
  14. #    V0.2, 01 Jan 2009, Phil Harnish <philharnish@gmail.com>
  15. #                         Support `git diff --color` output by
  16. #                         matching ANSI codes that specify only
  17. #                         bold or background colour.
  18. #                       P@draigBrady.com
  19. #                         Support `ls --color` output by stripping
  20. #                         redundant leading 0s from ANSI codes.
  21. #                         Support `grep --color=always` by stripping
  22. #                         unhandled ANSI codes (specifically ^[[K).
  23. #    V0.3, 20 Mar 2009, http://eexpress.blog.ubuntu.org.cn/
  24. #                         Remove cat -v usage which mangled non ascii input.
  25. #                         Cleanup regular expressions used.
  26. #                         Support other attributes like reverse, ...
  27. #                       P@draigBrady.com
  28. #                         Correctly nest <span> tags (even across lines).
  29. #                         Add a command line option to use a dark background.
  30. #                         Strip more terminal control codes.
  31. #    V0.4, 17 Sep 2009, P@draigBrady.com
  32. #                         Handle codes with combined attributes and color.
  33. #                         Handle isolated <bold> attributes with css.
  34. #                         Strip more terminal control codes.
