# Convert ANSI (terminal) colours and attributes to HTML
# Licence: LGPLv2
# 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 <[email protected]>
# Support `git diff --color` output by
# matching ANSI codes that specify only
# bold or background colour.
# 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, ...
# 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, [email protected]
# Handle codes with combined attributes and color.
# Handle isolated <bold> attributes with css.
# Strip more terminal control codes.
# V0.15, 16 Oct 2013
# http://github.com/pixelb/scripts/commits/master/scripts/ansi2html.sh
