How to substite g** keymaps with \** keymaps

[filchristou]

I want to replace all gc[whatever] gb[whatever] with '\c[whatever]' and '\c[whatever]' correspondingly.
My Comment set up is:

require('Comment').setup{
 toggler = {
        ---Line-comment toggle keymap
        line = '\\cc',
        ---Block-comment toggle keymap
        block = '\\bc',
    },
    ---LHS of operator-pending mappings in NORMAL and VISUAL mode
    opleader = {
        ---Line-comment keymap
        line = '\\c',
        ---Block-comment keymap
        block = '\\b',
    },
    ---LHS of extra mappings
    extra = {
        ---Add comment on the line above
        above = '\\cO',
        ---Add comment on the line below
        below = '\\co',
        ---Add comment at the end of line
        eol = '\\cA',
    },
}

As a result now both the keymaps starting with \ and the ones with g are enabled.
How to disable all the Comments.nvim keymaps that start with g in order to substitute them with \ ?

I've also faced a similar problem, and neither redefining keymaps nor opting out of basic ones like this:

opts = {
  -- Disable default mappings
  mappings = {
    basic = false,
    extra = false,
  },
}

helped me.

What did help was explicitly redefining the g* keymap right after the Comment.setup() call.

So I ended up with the following config:

{
    'numToStr/Comment.nvim',
    opts = {
      -- Disable default mappings
      mappings = {
        basic = false,
        extra = false,
      },
    },
    config = function()
      local comment = require 'Comment'
      comment.setup()

      -- Redefine gb keymap right after Comment setup to avoid conflicts
      vim.keymap.set('n', 'gb', '<C-o>', { noremap = true, desc = 'Go [b]ack' })

      -- Custom keymaps
      vim.keymap.set('n', '<leader>/', function()
        require('Comment.api').toggle.linewise.current()
      end, { desc = 'Toggle comment' })
      vim.keymap.set(
        'v',
        '<leader>/',
        '<ESC><CMD>lua require("Comment.api").toggle.linewise(vim.fn.visualmode())<CR>',
        { desc = 'Toggle comment' }
      )
    end,
}

The default gcc keymap is (frusteratingly) an oversight with the current state of neovim itself. It's created in the execution of the runtime defaults, which is ran after all of your initial user configuration. On most distros, this will be somewhere such as: /usr/share/nvim/runtime/lua/vim/_defaults.lua

The easiest way to counter act this is to:
a) Set your keybinds in the lua/after portion of your configuration (you can remap g to whatever here and it should be what you want
Or if you're like me and don't want to use the after directory for a single file,
b) Create a function that assigns your keybinds, and call it in an autocommand

vim.api.nvim_create_autocmd("VimEnter", {
    callback = function()
        vim.keymap.set("n", "gcc", ...)
        -- ...
    end
})
