Re: [PATCH] Add rainbow-mode

[Niels Giesen <niels.giesen@gmail.com>]

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.
