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,
}
