#!/bin/sh # Convert ANSI (terminal) colours and attributes to HTML # Author: # http://www.pixelbeat.org/docs/terminal_colours/ # Examples: # ls -l --color=always | ansi2html.sh > ls.html # git show --color | ansi2html.sh > last_change.html # Generally one can use the `script` util to capture full terminal output. # Changes: # V0.1, 24 Apr 2008, Initial release # V0.2, 01 Jan 2009, Phil Harnish <philharnish@gmail.com> # Support `git diff --color` output by # matching ANSI codes that specify only # bold or background colour. # P@draigBrady.com # Support `ls --color` output by stripping # redundant leading 0s from ANSI codes. # Support `grep --color=always` by stripping # unhandled ANSI codes (specifically ^[[K). # V0.3, 20 Mar 2009, http://eexpress.blog.ubuntu.org.cn/ # Remove cat -v usage which mangled non ascii input. # Cleanup regular expressions used. # Support other attributes like reverse, ... # P@draigBrady.com # Correctly nest <span> tags (even across lines). # Add a command line option to use a dark background. # Strip more terminal control codes. # V0.4, 17 Sep 2009, P@draigBrady.com # Handle codes with combined attributes and color. # Handle isolated <bold> attributes with css. # Strip more terminal control codes. # V0.12, 12 Jul 2011 # http://github.com/pixelb/scripts/commits/master/scripts/ansi2html.sh if [ "$1" = "--version" ];
