indentlines-decorator

This is a implementation of indent lines using decoration provider api of neovim to resolve several hard problems of the well knonwn plugin indent-blankline.nvim:

• Work with horizontal scrolling.
• Indent lines of folded lines now will be correctly drawn on open.
• Completely sync with nvim window redrawing and never flicker.
• On demand redraw, only lines needing redrawn will be rerendered. Performance might be better on large screen.
• Incorporate idea from echasnovski/mini.indentscope to highlight cursor indent scope and not rely on treesitter which has bad perf on large file.

Special thanks to the mentioned plugins above.

Notice:

• This is a POC implementation and not well tested. Issues are generally expected.
• I won't maintain this actively in the near future. To use it, just copy the single source file to dotfiles. And feel free to use idea or implementation here.

Usage:

require("your_pasted_mod_name").setup({
    get_opts = function(bufnr)
        if vim.bo[bufnr].buftype == "" then -- or any test logic you want
            return { enabled = true }
        end
    end
})
