pretty much as the title states. Anyone know of a program or way to grab terminal output with colors and output this to html?

The question is what exactly you want to do.

If you want to convert the output of some program into HTML it should be possible by piping through a small perl script or something. If you want to do it with an interactive session this could be harder, especially if you also want to include the stuff you type.

Perhaps there's an easier way if you tell us what you’re trying to accomplish.

HTH

yes, let me expand on that. I am hoping to be able to print on a webpage the standard output I see in the terminal. More specifically Portage emerges, and grep output. I was hoping/thinking there would be a program around that would be able to print both colored output and translate whatever HTML character entities it runs into.

The KBtin MUD client (get it here) includes a decent ansi2html filter.
There's no need to build or install the whole thing, the filter is completely self-contained:
Code:
tar xzvf kbtin-1.0.11.tar.gz
cd kbtin-1.0.11
( . /etc/make.conf; gcc $CFLAGS -o ansi2html ansi2html.c )
strip ansi2html
install -m 755 ansi2html /usr/local/bin
install -m 644 ansi2html.1 /usr/local/man/man1

I know the above works because I have no need of a MUD client but stumbled onto its Subversion repository by googling for "ansi2html." :lol:

Writing the above as an ebuild is left as an exercise for the reader, I'm feeling entirely too lazy. :P

Sure, I'll bite.
app-text/ansi2html-1.0.11.ebuild:
# Copyright 1999-2008 Gentoo Foundation
# Distributed under the terms of the GNU General Public License v2
# $Header: $

inherit eutils

DESCRIPTION="Convert text with ANSI escape codes to HTML"
HOMEPAGE="http://kbtin.sourceforge.net"
SRC_URI="mirror://sourceforge/kbtin/kbtin-${PV}.tar.gz"

LICENSE="GPL-2"
SLOT="0"
KEYWORDS="~amd64 ~x86"
IUSE=""

DEPEND=""
RDEPEND=""

S="${WORKDIR}/kbtin-${PV}"

src_compile() {
   econf || die "econf failed"
   emake ansi2html || die "emake failed"
}

src_install() {
   dobin ansi2html || die
   doman ansi2html.1 || die
}

Enjoy. Seems to work nicely - I'll be keeping this one around.

Note, though, that if portage detects that its output isn't going to a terminal it will automatically disable coloured output. You can force it with the --color option, like so:
Code:
emerge -vp --color y portage | ansi2html > portage-with-colour.html

Likewise.
Most tools that colorize output (ls, grep, etc.--not just emerge) suppress color unless told otherwise when they detect standard output is not a tty. Many if not all provide a switch to force color, but it varies.

Thanks timebandit for letting me know about this and thanks tarpman for the ebuild! I blog pretty often about linux and this helps tremendously. Good to know this is possible.

:D :D :D
