How to enable visual mode copy content into the clipboard

Just add this line into the config in <your path>/lua/l3azh/set.lua

vim.opt.clipboard="unnamedplus"

DAP-Using nvim-dap for debug

Using this packeage Nvim-dap

Config for go:

1. Get package via Packer plugin: use 'mfussenegger/nvim-dap'
2. Using Mason from the LSP-zero plugin to install those packages: delve(This package is required for debug), golangci-lint, gopls, gotests
3. Creating a config and a adpater for dap-go: <your path>/after/plugin/nvim_dap.lua as following content:

local dap = require("dap") 
dap.adapters.delve = {
  type = 'server',
  port = '${port}',
  executable = {
    command = 'dlv',
    args = {'dap', '-l', '127.0.0.1:${port}'},
  }
}

-- https://github.com/go-delve/delve/blob/master/Documentation/usage/dlv_dap.md
dap.configurations.go = {
  {
    type = "delve",
    name = "Debug",
    request = "launch",
    program = "${file}"
  },
  {
    type = "delve",
    name = "Debug test", -- configuration for debugging test files
    request = "launch",
    mode = "test",
    program = "${file}"
  },
  -- works with go.mod packages and sub packages 
  {
    type = "delve",
    name = "Debug test (go.mod)",
    request = "launch",
    mode = "test",
    program = "./${relativeFileDirname}"
  } 
}

4. Creating key-maping:

vim.keymap.set('n', '<F7>', function() require('dap').continue() end)
vim.keymap.set('n', '<F8>', function() require('dap').step_over() end)
vim.keymap.set('n', '<F9>', function() require('dap').step_into() end)
vim.keymap.set('n', '<F10>', function() require('dap').step_out() end)
vim.keymap.set('n', '<Leader>b', function() require('dap').toggle_breakpoint() end)
vim.keymap.set('n', '<Leader>B', function() require('dap').set_breakpoint() end)
vim.keymap.set('n', '<F5>', function()
    local widgets = require('dap.ui.widgets')
    local my_sidebarsc = widgets.sidebar(widgets.scopes)
    my_sidebarsc.open()
    local my_sidebarsf = widgets.sidebar(widgets.frames)
    my_sidebarsf.open()
end)

5. Done - Formore detail please watch Debugging In Neovim (ft BashBunni) or read document on Nvim-dap
