Remove indent guide on empty lines

[omi-donlimit]

See line 47, that's an empty line and the | shouldnt appear. Using default config and tabs as indentation character with no expandtab

[lukas-reineke]

I cannot reproduce this.

Can you make a minimal init.lua and a code example for which this happens?

[omi-donlimit]

I'm using AstroVim, here's the config file

local M = {}

function M.config()
    local status_ok, indent_blankline = pcall(require, "indent_blankline")
    if not status_ok then
        return
    end

    vim.g.indentLine_enabled = 1
    vim.g.indent_blankline_show_trailing_blankline_indent = true
    vim.g.indent_blankline_show_first_indent_level = true
    vim.g.indent_blankline_use_treesitter = true
    vim.g.indent_blankline_show_current_context = true
    vim.g.indent_blankline_char = "▏"
    vim.g.indent_blankline_buftype_exclude = {
        "nofile",
        "terminal",
        "lsp-installer",
        "lspinfo",
    }
    vim.g.indent_blankline_filetype_exclude = {
        "help",
        "startify",
        "dashboard",
        "packer",
        "neogitstatus",
        "NvimTree",
        "neo-tree",
        "Trouble",
    }
    vim.g.indent_blankline_context_patterns = {
        "class",
        "return",
        "function",
        "method",
        "^if",
        "^while",
        "jsx_element",
        "^for",
        "^object",
        "^table",
        "block",
        "arguments",
        "if_statement",
        "else_clause",
        "jsx_element",
        "jsx_self_closing_element",
        "try_statement",
        "catch_clause",
        "import_statement",
        "operation_type",
    }

    vim.opt.list = true
    vim.opt.listchars:append("space:⋅")
    vim.opt.listchars:append("eol:↴")

    indent_blankline.setup {
        show_current_context = true,
        show_current_context_start = false,
        show_end_of_line = true,
        space_char_blankline = " ",
    }
end

return M

Can you also share the code from the screenshot? Or any code snipped where this happens

[omi-donlimit]

Happens on any code for me, lua or cpp code are what I've tested it with.

Snippet:

std::string Test() const
{
    while (true)
    {
        std::string substr = s1.seq.substr(i, j);
        if (substr.length() < min_size)
            continue;

        size_t pos = s2.seq.find(substr, 0);
        while (pos != std::string::npos)
        {
            count++;
            pos = s2.seq.find(substr, pos + 1);
        }
    }
    return "";
}

Thank you, I can reproduce.

This happens because of vim.g.indent_blankline_use_treesitter = true. Treesitter indent isn't that great yet. Sometimes it makes these mistakes.

You can open an issue in the treesitter grammar repo. It's a bug there, not in indent-blankline.

I don't use treesitter for this myself, because of these issues. The default algorithm built into indent-blankline usually does a better job. It should work fine if you do vim.g.indent_blankline_use_treesitter = false

Thank you! Im new to neovim, still migrating from vim.

Hi @lukas-reineke,

Not sure if I'm missing something, but I can still see indents on blank lines.

@chalmagean

What's your config look like? Did you vim.g.indent_blankline_use_treesitter = false?

[lukas-reineke]

You have trailing whitespace on that line

[chalmagean]

Yes. Exactly. I don't want to see indent guides there.

Is that different from the setup block? I thought that by putting it there, it was the same thing.

[lukas-reineke]

Yes. Exactly. I don't want to see indent guides there.

There is no way to turn this off. I explicitly don't hide it, so you don't miss it and can remove it. It's a feature not a bug.

I don't see the point of having both a dot to indicate whitespace, and the indent guide.
