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

Install

Requirement

Neovim0.7

nvim-lspconfig

gopls

Install

Packer

use {
    'crusj/hierarchy-tree-go.nvim',
    requires= 'neovim/nvim-lspconfig'
}

Start

require("hierarchy-tree-go").setup()

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",

        -- bufkeymap
        expand = "o", -- expand or collapse hierarchy
        jump = "<CR>", -- jump
        move = "<space><space>" -- switch the hierarchy window position, must be current win
    }
})
