Returning English characters in which-key

[IvanKarpov-1]

As far as I understood, the README section on which-key contains code that should return English characters back to which-key. I have rewritten this code for myself, but still have Cyrillic in which-key.

How can I make sure that the which-key does not have Cyrillic characters?

Which-key output:

langmapper configuration:

return {
    "Wansmer/langmapper.nvim",
    lazy = false,
    priority = 1,
    config = function()
        local langmapper = require("langmapper")

        langmapper.setup({})
    end,
}

Which-key configuration:

return {
    "folke/which-key.nvim",
    enabled = true,
    dependencies = { "Wansmer/langmapper.nvim" },
    config = function()
        vim.o.timeout = true
        vim.o.timeoutlen = 300

        local lmu = require("langmapper.utils")
        local view = require("which-key.view")
        local execute = view.execute

        view.execute = function(prefix_i, mode, buf)
            prefix_i = lmu.translate_keycode(prefix_i, "default", "ru")
            execute(prefix_i, mode, buf)
        end

        require("which-key").setup()
    end,
}

Also, I didn't quite understand how to set up mapping for other keyboard layouts other than ru.

I defined the langmap option to the layout I need and called the langmapper plugin simply as langmapper.setup({}) and it seems to work.

But in the standard configuration of the plugin there is a section that configures it, it seems, only for Russian.

  layouts = {
    ---@type table Fallback layout item. Name of key is a name of language
    ru = {
      ---@type string Name of your second keyboard layout in system.
      ---It should be the same as result string of `get_current_layout_id()`
      id = 'com.apple.keylayout.RussianWin',
      ---@type string Fallback layout to translate. Should be same length as default layout
      layout = 'ФИСВУАПРШОЛДЬТЩЗЙКЫЕГМЦЧНЯБЮЖЭХЪËфисвуапршолдьтщзйкыегмцчнябюжэхъё',
      ---@type string if you need to specify default layout for this fallback layout
      default_layout = nil,
    },
  },

So I'm a little confused whether I'm using the plugin correctly.

I looked at the other issues and saw that I need to add hack_get_keymap() after calling setup() so that the which-key does not contain Cyrillic.

Now the question of keyboard layouts for other languages remains.

Now the question of keyboard layouts for other languages remains.

To add another language, you need to add a new layout to layouts (with all fields as in Russian layout), e.g:

require("langmapper").setup({
  layouts = {
    ---@type table Fallback layout item. Name of key is a name of language
    ru = { --[[layout preset]] },
    fr = { --[[layout preset]] },
    gr = { --[[layout preset]] },
  },
})

Also, don't forget to set vim.opt.langmap for the additional input method.

I did, but I kept getting errors, so I asked about it because I thought I was doing something wrong.

Errors:

I was able to fix it by setting hack_keymap to false. This seemed to fix the problem, but I haven't used Neovim long enough after that to try all the keyboard shortcuts I use, so I can't say for sure.

Now my settings look like this. langmapper configuration:

return {
    "Wansmer/langmapper.nvim",
    lazy = false,
    priority = 1,
    config = function()
        local langmapper = require("langmapper")

        langmapper.setup({
            hack_keymap = false,
            layouts = {
                ua = {
                    id = "ua",
                    layout = "ФИСВУАПРШОЛДЬТЩЗЙКІЕГМЦЧНЯБЮЖЄХЇʼ,фисвуапршолдьтщзйкіегмцчнябюжєхї'.",
                    default_layout = [[ABCDEFGHIJKLMNOPQRSTUVWXYZ<>:"{}~?abcdefghijklmnopqrstuvwxyz,.;'[]`/]],
                }
            },
            os = {
                Linux = {
                    get_current_layout_id = function()
                        local cmd = "gsettings"
                        if vim.fn.executable(cmd) then
                            local output = vim.fn.system(
                                cmd .. " get org.gnome.desktop.input-sources mru-sources | sed -r \"s/\\S*\\s'([^']+).*/\\1/\""
                            )
                            return output
                        end
                    end,
                },
            },
        })

        langmapper.hack_get_keymap()
    end,
}

options.lua:

local function escape(str)
    local escape_chars = [[;,."|\]]
    return vim.fn.escape(str, escape_chars)
end

local en = [[abcdefghijklmnopqrstuvwxyz,.;'[]`/]]
local ua = [[фисвуапршолдьтщзйкіегмцчнябюжєхї'.]]
local en_shift = [[ABCDEFGHIJKLMNOPQRSTUVWXYZ<>:"{}~?]]
local ua_shift = [[ФИСВУАПРШОЛДЬТЩЗЙКІЕГМЦЧНЯБЮЖЄХЇʼ,]]
vim.opt.langmap = vim.fn.join({ escape(ua_shift) .. ";" .. escape(en_shift), escape(ua) .. ";" .. escape(en) }, ",")

I also added require("langmapper").automapping({ global = true, buffer = true }) to the end of init.lua.
