Hierarchy

What is it?

hierarchy.nvim replicates the "Call Hierarchy" functionality from VS C*de, showing (recursively) the functions that a given function calls.

Functionality

With your LSP enabled, hover over a function, use the :FunctionReferences command, and observe the call hierarchy of that function. Press <Enter> over an item in the list to expand its list of children, and type gd over an item to jump to its definition.

Installation

Using lazy:

return {
    'lafarr/hierarchy.nvim'
}

Default Options

local opts = {
    -- Determines how many levels deep the call hierarchy shows
    depth = 3
}

Usage

In your init.lua:

vim.api.nvim_create_autocmd({ 'LspAttach' }, {
    group = 'Hierarchy',
    desc = 'Set up the :FunctionReferences user command',
    callback = function()
        local opts = {
            -- Your opts here
        }
        require('hierarchy').setup(opts)
    end
})

Now, navigate your cursor over a function and use the :FunctionReferences command
