I won't develop this plugin anymore since I found which-key far better than mine: https://github.com/folke/which-key.nvim

🔭 telescope-command-palette.nvim

telescope-command-palette.nvim is a neovim plugin written entirely in lua that will help you to access your custom commands/function/key-bindings.

Demo

Installation

Vim-Plug

Plug "nvim-telescope/telescope.nvim"
Plug "LinArcX/telescope-command-palette.nvim"

Packer

use { "nvim-telescope/telescope.nvim" }
use { "LinArcX/telescope-command-palette.nvim" }

Setup and Configuration

First set up your commands in your Telescope config:

require('telescope').setup({
  extensions = {
    command_palette = {
      {"File",
        { "entire selection (C-a)", ':call feedkeys("GVgg")' },
        { "save current file (C-s)", ':w' },
        { "save all files (C-A-s)", ':wa' },
        { "quit (C-q)", ':qa' },
        { "file browser (C-i)", ":lua require'telescope'.extensions.file_browser.file_browser()", 1 },
        { "search word (A-w)", ":lua require('telescope.builtin').live_grep()", 1 },
        { "git files (A-f)", ":lua require('telescope.builtin').git_files()", 1 },
        { "files (C-f)",     ":lua require('telescope.builtin').find_files()", 1 },
      },
      {"Help",
        { "tips", ":help tips" },
        { "cheatsheet", ":help index" },
        { "tutorial", ":help tutor" },
        { "summary", ":help summary" },
        { "quick reference", ":help quickref" },
        { "search help(F1)", ":lua require('telescope.builtin').help_tags()", 1 },
      },
      {"Vim",
        { "reload vimrc", ":source $MYVIMRC" },
        { 'check health', ":checkhealth" },
        { "jumps (Alt-j)", ":lua require('telescope.builtin').jumplist()" },
        { "commands", ":lua require('telescope.builtin').commands()" },
        { "command history", ":lua require('telescope.builtin').command_history()" },
        { "registers (A-e)", ":lua require('telescope.builtin').registers()" },
        { "colorshceme", ":lua require('telescope.builtin').colorscheme()", 1 },
        { "vim options", ":lua require('telescope.builtin').vim_options()" },
        { "keymaps", ":lua require('telescope.builtin').keymaps()" },
        { "buffers", ":Telescope buffers" },
        { "search history (C-h)", ":lua require('telescope.builtin').search_history()" },
        { "paste mode", ':set paste!' },
        { 'cursor line', ':set cursorline!' },
        { 'cursor column', ':set cursorcolumn!' },
        { "spell checker", ':set spell!' },
        { "relative number", ':set relativenumber!' },
        { "search highlighting (F12)", ':set hlsearch!' },
      }
    }
  }
})

And then load the extension:

require('telescope').load_extension('command_palette')

The idea is that you declare some categories("Help", "Vim", etc..) and inside each category, you define your commands. Each command has three parts:

description(mandatory)
command(mandatory)
insert_mode/normal_mode flag(optional) (indicates that whether you want to be in insert_mode after run the command or not. 1 means: insert mode. everything else is normal mode)

Tip: CpMenu is just a simple table.

Per project configurations

If you're working on different projects and want to have special key_bindings per project, you can create a .nvimrc file in root of your project and append items to CpMenu like this:

table.insert(require('command_palette').CpMenu,
  {"Dap",
    { "pause", ":lua require'dap'.pause()" },
    { "step into", ":lua require'dap'.step_into()" },
    { "step back", ":lua require'dap'.step_back()" },
    { "step over", ":lua require'dap'.step_over()" },
    { "step out", ":lua require'dap'.step_out()" },
    { "frames", ":lua require'telescope'.extensions.dap.frames{}" },
    { "current scopes", ":lua ViewCurrentScopes(); vim.cmd(\"wincmd w|vertical resize 40\")" },
    { "current scopes floating window", ":lua ViewCurrentScopesFloatingWindow()" },
    { "current value floating window", ":lua ViewCurrentValueFloatingWindow()" },
    { "commands", ":lua require'telescope'.extensions.dap.commands{}" },
    { "configurations", ":lua require'telescope'.extensions.dap.configurations{}" },
    { "repl", ":lua require'dap'.repl.open(); vim.cmd(\"wincmd w|resize 12\")" },
    { "close", ":lua require'dap'.close(); require'dap'.repl.close()" },
    { "run to cursor", ":lua require'dap'.run_to_cursor()" },
    { "continue", ":lua require'dap'.continue()" },
    { "clear breakpoints", ":lua require('dap.breakpoints').clear()" },
    { "brakpoints", ":lua require'telescope'.extensions.dap.list_breakpoints{}" },
    { "toggle breakpoint", ":lua require'dap'.toggle_breakpoint()" },
  })

Default mappings (insert mode):

Key	Description
`c-b`	go back to categories

Default mappings (normal mode):

Key	Description
`c-b`	go back to categories

Usage

:Telescope command_palette.

Roadmap 🚙

✔️ use modules and setup function. (Thanks to: mrjones2014)
let users chose the separator icon.
make categories per os/distro.
allow users to define keybindings for items in categories/commands.
remember the selected item in come back to categories.
show frequently commands based on frecency algorithm.
add options to make telescope-command-palette.nvim more like vscode command-palatte. (like: @, ...)
