Attribute completion task on css-mode

Attribute completion task on css-mode

[Etienne Prud'homme]

Hi.

Bug#20107 introduced a new feature in css-mode. It’s property
completion. So far, it seems to be quite good. In the Todo section,
there’s “attribute value completion”. I’m assuming that it means
property values completion since there are attribute selectors in CSS.

I was wondering what would be best to include in Emacs. There are
already several packages that do that very well. If css-mode is to
contain property value completion, should it be context aware (should
it give values according to property).

company-css already implements that behaviour by making a list of
attributes & their corresponding valid values. It could be one way to
do, but may be hard to maintain since CSS specifications are
always changing.

Another way would be to make a Semantic language parser. It would give
much more power for doing complex things.

The first step would probably be to move the company-css functionality
in css-mode.el.

Hi, Etienne!

Thanks for trying it out. It's been on my mind for a long time to
extend it to work for attribute values as well. I haven't gotten
around to it yet, but I hope I will soon.

Like Stefan, I also think it would be a great first step to move
functionality from company-css into css-mode.el.
