⚑️ Requirements

πŸ“¦ Installation

Install the plugin with your preferred package manager:

packer

use {
    "SmiteshP/nvim-navbuddy",
    requires = {
        "neovim/nvim-lspconfig",
        "SmiteshP/nvim-navic",
        "MunifTanjim/nui.nvim",
        "numToStr/Comment.nvim",        -- Optional
        "nvim-telescope/telescope.nvim" -- Optional
    }
}

vim-plug

Plug "neovim/nvim-lspconfig"
Plug "SmiteshP/nvim-navic"
Plug "MunifTanjim/nui.nvim"
Plug "numToStr/Comment.nvim",        " Optional
Plug "nvim-telescope/telescope.nvim" " Optional
Plug "SmiteshP/nvim-navbuddy"

Lazy Loading

If you want to lazy load navbuddy you need to load it before your Lsp related Stuff.

For Example with Lazy and lspconfig

return {
    "neovim/nvim-lspconfig",
    dependencies = {
        {
            "SmiteshP/nvim-navbuddy",
            dependencies = {
                "SmiteshP/nvim-navic",
                "MunifTanjim/nui.nvim"
            },
            opts = { lsp = { auto_attach = true } }
        }
    },
    -- your lsp config or other stuff
}

βš™οΈ Setup

nvim-navbuddy needs to be attached to lsp servers of the buffer to work. You can pass the navbuddy's attach function as on_attach while setting up the lsp server. You can skip this step if you have enabled auto_attach option in setup function.

Example:

local navbuddy = require("nvim-navbuddy")

require("lspconfig").clangd.setup {
    on_attach = function(client, bufnr)
        navbuddy.attach(client, bufnr)
    end
}

πŸͺ„ Customise

Use setup to override any of the default options

  • icons : Indicate the type of symbol captured. Default icons assume you have nerd-fonts.
  • node_markers : Indicate whether a node is a leaf or branch node. Default icons assume you have nerd-fonts.
  • window : Set options related to window's "border", "size", "position".
  • use_default_mappings: If set to false, only mappings set by user are set. Else default mappings are used for keys that are not set by user.
  • mappings : Actions to be triggered for specified keybindings. For each keybinding it takes a table of format { callback = <function_to_be_called>, description = "string"}. The callback function takes the "display" object as an argument.
  • lsp :
    • auto_attach : Enable to have Navbuddy automatically attach to every LSP for current buffer. Its disabled by default.
    • preference : Table ranking lsp_servers. Lower the index, higher the priority of the server. If there are more than one server attached to a buffer, navbuddy will refer to this list to make a decision on which one to use. for example - In case a buffer is attached to clangd and ccls both and the preference list is { "clangd", "pyright" }. Then clangd will be prefered.
  • source_buffer :
    • follow_node : Keep the current node in focus on the source buffer
    • highlight : Highlight the currently focused node
    • reorient: Reorient buffer after changing nodes. options are "smart", "top", "mid" or "none"

πŸš€ Usage

Navbuddy command can be used to open navbuddy.

:Navbuddy

And alternatively lua function open can also be used to open navbuddy.

:lua require("nvim-navbuddy").open()
