Hi, I'm getting the following selection behavior with default setup:

vip:

With master, I get

Is this intended?

[simonmandlik]

Isn't this a bit strict?

I cannot for example use a custom hlg, which is not set by the colorscheme itself.

minimal.lua:

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath, })
end
vim.opt.runtimepath:prepend(lazypath)

vim.cmd [[hi MyHLG guifg=red]]

-- install plugins
local plugins = {
    {
        "lukas-reineke/indent-blankline.nvim",
        branch = "v3",
        config = function()
            require("ibl").setup {
                indent = { highlight = "MyHLG" },
            }
        end
    },
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

vim.cmd [[set termguicolors]]

Now when I run for example colorscheme default, it clears MyHLG, and when the autocommand runs it errors

You need to use the HIGHLIGHT_SETUP hook, it's explained in the readme and the docs

https://github.com/lukas-reineke/indent-blankline.nvim/tree/v3#multiple-indent-colors

For the visual selection, I can't reproduce that. Please open an issue with steps to get there.

Hmm, yes you are right. I just skimmed :h ibl.setup() (as recommended) and scrolled to config.indent. Out of curiosity — is there a reason why hooks are necessary here? None of other plugins I use with custom hl groups require that (tzachar/highlight-undo.nvim, winston0410/range-highlight.nvim, folke/flash.nvim to name a few), and their config is more concise.

About the highlighting — I'm not sure it is an "issue" per see, but side effect of how highlights are handled as well. Try this

local root = vim.fn.fnamemodify("./.repro", ":p")
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath, })
end
vim.opt.runtimepath:prepend(lazypath)

local plugins = {
    "RRethy/nvim-base16",
    {
        "lukas-reineke/indent-blankline.nvim",
        branch = "v3",
        config = function()
            require("ibl").setup { }
        end
    },
}

require("lazy").setup(plugins, {
    root = root .. "/plugins",
})

vim.cmd [[set termguicolors]]
vim.cmd [[colorscheme base16-dirtysea]]
vim.opt.background = "light"
vim.api.nvim_set_hl(0, "NonText",  { fg = "Gray", bg = "bg" })

Anyway, thanks for the hard work on this plugin!

I agree it's not ideal, but I don't see a better way. Because there can be different colors for the indent guides, the scope, and the whitespace, I need to generate all combinations for all cases where they are used.

Otherwise, to have 3 colors each, the user would need to manually make 42 highlight groups. That would be much less user-friendly.
Even with just one color each, I still need to create 7 highlight groups.
