In putting together and addon for blender to integrate neovim.

Where I'm at with it, github colo imported to blender text editor from nvim_gtk

One component is grabbing the current colorscheme of a running vim and importing it into blender's text editor theme

So far I have some re code that looks at the return of hi and follows links if need be till I get a guifg or guibg

# vim is a pynvim.api.nvim.Nvim object
vim_color = vim.command_output(f"highlight g")

which for g = "pythonBuiltin" returns

pythonBuiltin xxx links to GruvboxOrange

and so on

GruvboxOrange xxx ctermfg=208 guifg=#fe8019

in which case I can get the rgb colour for blender from the hex. Other colour codes not so easy. And the code is getting unwieldly.

Could you point me to a more direct way, possibly a plugin, to get the rgb value of a highlight?

Consider using the synIDattr() function, which can take special attributes such as fg# and bg# to return RGB for attributes, when a GUI is running.

"fg#" like "fg", but for the GUI and the GUI
 is running the name in "#RRGGBB" form
"bg#" like "fg#" for "bg"
"sp#" like "fg#" for "sp"

The first argument to this function is a numeric synID, if you have a file styled with syntax elements you can look up the id from a specific position in the file.

If you want to find all syntax groups, then perhaps you could iterate them starting from 1 and looking up the name with synIDattr(..., 'name') to build a full map from name to RGB attributes.

For instance, to get the RGB for the foreground color of pythonComment, you can use the following command:

echo synIDattr(synIDtrans(hlID("pythonComment")), "fg#")

I don't know about any plugins for this but it should be easy to code up lookup tables for the other codes.

The decimal numbers, like 208 in your example, are 256-color palette codes. It's easy to find translations to/from hex code. Like the top of the google search for 256 color to hex.

The spelled-out colors (e.g. DarkSeaGreen4) are system dependent. You didn't mention what system you're using, I don't think. But for *nix that same translation page includes spelled colors, too.. For windows start with :h win32-colors and go from there.
