First let me say that this first beta is quite impressive and I have the feeling that it’ll be one of the most promising webdev tool in the near future.
Now let’s move to the main topic.
I started to dig a bit in the sources of the various packages in order to figure how to make a plugin that highlights color codes (hexa, rgb, etc) in a file by applying a background color to the color declaration (as FDT does for instance). I figured out how I could place an element behind some text parts using markers (as done by the find-and-replace package), but the issue here is that it doesn’t modify the color declaration itself, leading to poor contrast depending of the color and theme.
So, I was wondering if there was a preferred way to dynamically add rules to the grammar used on a particular editor view ? Is it simply possible ?
