hierarchy-tree-go

Hierarchy ui tree for go

Description

nvim-lspconfig displays incoming and outgoing in quickfix, which does not display hierarchical relationships and perform hierarchical expansion operations, so I wrote such a plugin.

Feature

Display the call chain of the symbol under the cursor, including incoming and outgoing

Expand or collapse the upper or lower call chain

Ability to switch window position, editor center, or bottom right corner via mapkey

Highlight in the current module or others module

The icon of the last layer of the call chain will change to ☉

Configurable

Default config

require("hierarchy-tree-go").setup({
	icon = {
		fold = "", -- fold icon
		unfold = "", -- unfold icon
		func = "₣", -- symbol
		last = '☉', -- last level icon
	},
	hl = {
		current_module = "guifg=Green", -- highlight cwd module line
		others_module = "guifg=Black", -- highlight others module line
		cursorline = "guibg=Gray guifg=White" -- hl  window cursorline
	},
	keymap = {
		--global keymap
		incoming = "<space>fi", -- call incoming under cursorword
		outgoing = "<space>fo", -- call outgoing under cursorword
		open = "<space>ho", -- open hierarchy win
		close = "<space>hc", -- close hierarchy win
		-- focus: if hierarchy win is valid but is not current win, set to current win
		-- focus: if hierarchy win is valid and is current win, close
		-- focus  if hierarchy win not existing,open and focus
		focus = "<space>fu",

		jump = "<CR>", -- jump
		move = "<space><space>" -- switch the hierarchy window position, must be current win
