Border colors

[BigfootN]

Hello,

I would like to set border colors but it seems like nvim_set_hl doesn't seem to affect the popup. I'm using noice.nvim but the backend is nui.

Here is my configuration:

return {
    "folke/noice.nvim",
    dependencies = {
        "MunifTanjim/nui.nvim"
    },
    opts = {
        cmdline = {
            enabled = true,
            view = 'cmdline_popup',
        }
    },
    config = function(_, opts)
        vim.api.nvim_set_hl(0, 'FloatBorder', { bg = '#3B4252', fg = '#5E81AC' })
        vim.api.nvim_set_hl(0, 'NormalFloat', { bg = '#3B4252' })
        require("noice").setup(opts)
        vim.api.nvim_set_hl(0, 'FloatBorder', { bg = '#3B4252', fg = '#5E81AC' })
        vim.api.nvim_set_hl(0, 'NormalFloat', { bg = '#3B4252' })
    end
}

The color is the same as with the default configuration.

Thank you very much in advance for any help

You should ask this in noice.nvim repo. I don't know how noice.nvim uses highlight groups... It doesn't necessarily has to be the default FloatBorder/NormalFloat. Also the first parameter f nvim_set_hl is the namespace. noice.nvim could be using a different namespace (not the default 0).

Thank you for your quick response and help.

I finally figured it out. For anyone interested, the documentation of noice clearly indicates the used highlight groups.

So this example works:

config = function(_, opts)
    require("noice").setup(opts)
    vim.api.nvim_set_hl(0, 'NoiceCmdlinePopupBorderCmdline', { fg = "#e78a4e" })
end

Thank you for your time and sorry for wasting it.
