Question: what's the point of caching the last state of transparency?

[pocco81]

I don't really get it. Is it supposed to be used for synchronizing transparency states? Is it to load the last stage of transparency? If it's the latter then I don't think it works that well. Because say transparency_cache has true. But then I go to open a neovim instance where transparency is not enabled at lunch, and when I run :TransparentToggle I expect to enable transparency, but since the plugin first reads the cached file, it will try to disable transparency.

Correct me if I'm wrong, but I think the logic is faulty? I had some issues with it so I rewrote M.toggle():

-- note: I also removed the initial `cache.read()` at the top of `init.lua` because I'm not using it here

function M.toggle(opt)
    opt = opt == nil and not vim.g.transparent_enabled or opt
    if opt == vim.g.transparent_enabled then return end

    vim.g.transparent_enabled = opt

    if opt then
        clear()
    else
        pcall(vim.cmd.colorscheme, vim.g.colors_name)
    end
end

Let me know if I should make a PR.

Ah, I just read the bottom line on the README. So this is supposed to enable transparency at startup, right?

In that case, with the logic above, this should be appended:

-- at the bottom of `setup()` at `config.lua`
if cache.read() then
    require("transparent").toggle(vim.g.transparent_enabled)
end

-- where `cache.read()` should return true or false depending on `transparent_cache`

-- at the bottom of `toggle()` at `init.lua`
cache.write()

This is better because:

1. vim.g.transparent_enabled should ideally track exclusively the state of transparency of its running NeoVim instance, and thus avoid being affected by said caching
2. I personally don't really care about the caching, so it'd be cool to have a setting one could tweak like caching = false
3. And perhaps it'd be better to only save the cache at VimLeave?

I'm not sure about your question as everything seems normal on my end. Could you please share your configuration for reference?
