Hi there,
I'm glad to present rainbow-mode. This is a minor mode that displays color
names with colored background.
This means that if you type #ff0000 it will displays that string, #ff0000,
with a red background.
It supports several major mode, like LaTeX, HTML/CSS, etc. This allows to also
diplays strings like
\definecolor{blue}{RGB}{0, 0, 255}
in blue for latex, or
rgb(255, 0, 0)
in red for CSS.
A lot of people found this mode very useful, and I got a ton of feedback in
the last weeks, with several requests to submit rainbow-mode to emacs trunk.
So here it is.

Hi Julien,
There is (since two years) a minor mode, css-color-mode in
css-color.el written by Niels Giesen, in nXhtml which can do the same
thing and quite a bit more. Perhaps you and Niels can coordinate your
efforts? (Some things might need a bit work in css-color.el, for
example the handling of undo could be a bit better.)
See http://bazaar.launchpad.net/~nxhtml/nxhtml/main/files/head:/util/

I looked at all of them and rainbow-mode seems to be a superset of their
functionality (except for highlighting "blue" in blue, for instance).
It's definitely more configurable and smarter about the major mode. The
name may have to change so it's clearer what it does: visual-color.el,
perhaps?
I'd like to see it become part of Emacs; it would be useful to me and
probably many others.

I do not think rainbow-mode has all the functionality in
css-color-mode (but I only glanced at rainbow-mode so I am not quite
sure). Are you really sure of this?

I checked this as well, it looks like `rainbow-mode' is mode sensitive
(among other things to consider).

I've looked at it too, it has a lot of functionality (including hs[vl]-rgb
conversions). And defines more colours. However it is more heavy weight
and CSS specific.
If I have a right to vote, I would try to include some funcionality from
`css-color-mode' into `rainbow-mode', because of both of them have
potential, and rainbow-mode seems to be more generic...

I think it would be a right thing to do, but also see above.
Just mine two cents.

In what way is rainbow-mode more generic?

OK, I tried to run it actually, and no, it does not require anything
else then turning on the minor mode dependent on a fontlock. Generic
meant, that `css-color' module name is a just little bit
misleading. Also, rainbow mode seems to support among CSS, LaTeX and
HTML.

I agree it doesn't have all the CSS-specific functionality. Is there
something specific you need?
rainbow-mode.el is more generally useful and can support the
CSS-specific code, whereas css-color-mode.el can't support tex-mode for
instance. So my vote is still for rainbow-mode.el.

I would be glad to get Niels comments on this. I do not think there is
much that is very css-specific. (For example the conversion between
different color notations could be useful in other places).

I am surprised to read that, but then perhaps functionality from the
both minor modes should be merged?

I have seen HSV and HSL conversions, pluss css-color-mode works
in every mode. The name is a bit specific only.

Yes, I think it should be.

Hi all,
Sorry for chiming in this late, but I had little time. So here are my thoughts.
This morning I finally got a chance to look at rainbow-mode. I must
say I like the clearness of the code. I definitely want to see wether
css-color.el can learn from it.
It seems rainbow-mode is less css-specific or more generic in that it
also handles LaTeX colors and x-defined-colors. On the other hand,
rainbow-mode does not handle all color notations valid in css (no
hsl()).
Css-color-mode currently only handles colors that are (also) valid css-colors.
In my view, the biggest plus of css-color are the conversions, whereas
the biggest plus of rainbow-mode is the automatic handling of
major-modes.
I would be open to add support for more color notations, possibly
user-configurable.
We may make `css-color-type-circle' buffer-local and use
rainbow-mode's handling of major modes to set the appropriate ring.
This means adding appropriate conversion functions, and bailing out
when the ring contains just one type (i.e., new type == old type).
We could opt to still do font-locking of all color notations
regardless of the major-mode, or split up font-lock-keywords the same
way that rainbow-mode does.
Regards,
Niels.

Even if rainbow-mode.el were included in Emacs with the HSL/HSV
conversions, it sounds like you still want to continue developing
css-color.el (which is fine, of course). Woijciech and Lennart wanted
to merge the two; it seems unlikely based on your comments.
Right now rainbow-mode.el seems like a better fit for Emacs because it's
more generally useful. Do you have objections to that, or do you want
some time to add the features you mentioned to css-color.el and then we
can reevaluate things?
Julien, do you have any comments on the HSV/HSL conversions or any other
part of this conversation?

I've added rainbow-mode to the Emacs 24 package repository. Duplication
does not bother me, since neither css-color and rainbow-mode are very
large, but whether the developers of css-color and rainbow-mode want to
collaborate is up to them. Assuming the packages don't end up merging,
I am open to adding css-color to the repository as well.

I never heard of HSV/HSL (I'm not a web dev), but it seems trivial to
add support for that in rainbow mode, so I'll do it ASAP.
IMHO, we could merge both modes. I think I'll try to grab useful ideas
or pieces from css-color-mode. :-)

FWIW, I've added hsl() and hsla() support to rainbow-mode.

Wonderful. One of the maintainers will have to push it to the
elpa.gnu.org repo. Thanks for your work.

Sounds good.
However in css-color-mode there is also support for interactively
changing the colors. I think it is useful (but it needs some work
regarding buffer undo).

Still on my todo, if that's not too much work / too ugly.
