What can this plugin do

similar to indent-blankline, this plugin can highlight the indent line, and highlight the code chunk according to the current cursor position.

What is the advantage of this plugin

1. more extensible
2. faster rendering speed (0.04 seconds per thousand renderings, with the window have 50 lines)
3. more active maintenance (the author is a student with a lot of time to maintain this plugin, haha)

Brief introduction

this plugin now have five parts (future will add more... ^v^)

1. chunk
2. indent
3. line_num
4. blank
5. context (experimental)

The script comes with the following defaults:

{
    chunk = {
        enable = true,
        notify = true,
        use_treesitter = true,
        -- details about support_filetypes and exclude_filetypes in https://github.com/shellRaining/hlchunk.nvim/blob/main/lua/hlchunk/utils/filetype.lua
        support_filetypes = ft.support_filetypes,
        exclude_filetypes = ft.exclude_filetypes,
        chars = {
            horizontal_line = "─",
            vertical_line = "│",
            left_top = "╭",
            left_bottom = "╰",
            right_arrow = ">",
        },
        style = {
            { fg = "#806d9c" },
            { fg = "#c21f30" }, -- this fg is used to highlight wrong chunk
        },
        textobject = "",
        max_file_size = 1024 * 1024,
        error_sign = true,
    },

    indent = {
        enable = true,
        use_treesitter = false,
        chars = {
            "│",
        },
        style = {
            { fg = vim.fn.synIDattr(vim.fn.synIDtrans(vim.fn.hlID("Whitespace")), "fg", "gui") }
        },
    },

    line_num = {
        enable = true,
        use_treesitter = false,
        style = "#806d9c",
    },

    blank = {
        enable = true,
        chars = {
            "․",
        },
        style = {
            vim.fn.synIDattr(vim.fn.synIDtrans(vim.fn.hlID("Whitespace")), "fg", "gui"),
        },
    },
}

setup example:

require('hlchunk').setup({
    indent = {
