Plugin doesn't work out of the box

[simonmandlik]

Hi, thanks for working on this cool plugin. I decided to give it a try, because it seemed to have the most features, but can't make it work, even in vanilla vim.

repro.lua:

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 = {
    -- "Bekaboo/deadcolumn.nvim"
}

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

vim.cmd[[hi ColorColumn guibg=red]]
vim.cmd[[set textwidth=20]]
vim.cmd[[set colorcolumn=-10,25,+2]]

When I run nvim -u repro.lua test.txt, it works as expected

but when I uncomment the line with the plugin, install it and start typing, nothing happens

@simonmandlik Did you ever revisit this? I remember this plugin working in the past, but it seems inconsistent. I've saved a bunch of debug logs of opening various filetypes and I see deadcolumn setting the ColorColumn, but it's like it doesn't "stick". I tried the same as you with a vanilla neovim instance, but same situation - the column doesn't show with a global cc being set. It's like it has to be set at the buffer or window level with each new buffer.

@simonmandlik @Normanras I'am planning rewrite this plugin utilizing the winhl feature instead of changing the user option &cc (which is the current implementation) and that should make it much more stable. Right now this pligin is filled with hacky and unnessarily complecated code because winhl feature has bugs (see neovim/neovim#23016 and neovim/neovim#23227) back when this plugin was written.

[Normanras]

Awesome! I won't submit any issues then. I realized there was some weird stuff happening as it interacted with other plugins (notably, Folke's Styler), so good to know something more stable is coming. Let me know if you need any help!

@Normanras @simonmandlik

This plugin has been refactored to use winhl instead of messing around with cc and should be much stabler and act as expected now, see commit ce15b17, commit 0b27192

I've just tried the MWE from this issue and I am still getting no color column :(

@simonmandlik Hi, can you confirm the problem persists using the minimal config and nvim --clean -u minimal.lua? What version of neovim you are using?

[simonmandlik]

Yes, I'm on v0.10.0-dev-1506+g610f50dda-Homebrew

deadcolumn.mov

That's strange, I will see if I can reproduce it using the same version of neovim as yours. Currently I cannot reproduce using dev-2075, the plugin should work on both versions though.

@simonmandlik You didn't set &termgicolors. Color blending won't work using only term 16 colors. Try setting it using :set termguicolors.
