MenuHammer

A Spacemacs inspired menu system for macOS built for Hammerspoon.

example-menu

It displays user configured menus on the bottom of the screen. Each menu has series of menu items that can perform a series of actions when activated by the configured hotkey.

Those actions include:

  • Loading other menus
  • Opening applications
  • Getting user input
  • Executing a lua function
  • Executing key combinations
  • Typing text into current window
  • Executing a shell script (with root privileges if needed)
  • Executing a shell command
  • Opening a URL
  • Sleeping (pause) for a specified amount of time
  • Opening files
  • Apply window layouts

It has some default menus configured but you will most certainly want to customize it. Out of the box it will bind Command-Option-Control-q to enable/disable MenuHammer and Option-Space to show/hide MenuHammer.

It is still very much a work in progress. I have a large list of features I still want to add and some features are only partially implemented. Use at your own risk.

I've included the WinWin Spoon from Awesome Hammerspoon for resizing windows.

I'm new to both Hammerspoon and Lua so any feedback is welcome.

Installing

Install Hammerspoon.

Clone the repository and place MenuHammer.spoon in ~/.hammerspoon/Spoons

Add these two lines to your init.lua to load the menu when Hammerspoon starts:

    menuHammer = hs.loadSpoon("MenuHammer")
    menuHammer:enter()

For customizing menus, colors and other values, create a file called menuHammerCustomConfig.lua in ~/.hammerspoon and customize to your liking. Look at MenuHammer.spoon/MenuConfigDefaults.lua for what can be customized.

Example Configuration

Here is an example of a basic menu configuration that covers some of the things MenuHammer can do:

    menuHammerMenuList = {
        mainMenu = {
            parentMenu = nil,
            menuHotkey = {{'alt'}, 'space'},
            menuItems =  {
                {cons.cat.submenu, '', 'A', 'Applications', {
                      {cons.act.menu, "applicationMenu"}
                }},
                {cons.cat.action, '', 'T', "Terminal", {
                      {cons.act.launcher, 'Terminal'}
                }},
                {cons.cat.action, '', 'D', 'Desktop', {
                      {cons.act.launcher, 'Finder'},
                      {cons.act.keycombo, {'cmd', 'shift'}, 'd'},
                }},
                {cons.cat.action, '', 'E', "Split Safari/iTunes", {
                    {cons.act.func, function()
                          -- See Hammerspoon layout documentation for more info on this
                          local mainScreen = hs.screen{x=0,y=0}
                          hs.layout.apply({
                                  {"Safari", nil, mainScreen, hs.layout.left50, nil, nil},
                                  {"iTunes", nil, mainScreen, hs.layout.right50, nil, nil},
                          })
                    end }
                }},
                {cons.cat.action, '', 'H', "Hammerspoon Manual", {
                      {cons.act.func, function()
                          hs.doc.hsdocs.forceExternalBrowser(true)
                          hs.doc.hsdocs.moduleEntitiesInSidebar(true)
                          hs.doc.hsdocs.help()
                      end }
                }},
                {cons.cat.action, '', 'M', 'MenuHammer Default Config', {
                    {cons.act.openfile, "~/.hammerspoon/Spoons/MenuHammer.spoon/MenuConfigDefaults.lua"},
                }},
                {cons.cat.action, '', 'X', "Mute/Unmute", {
                      {cons.act.mediakey, "mute"}
                }},
            }
        },
        applicationMenu = {
            parentMenu = "mainMenu",
            menuHotkey = nil,
            menuItems = {
                {cons.cat.action, '', 'A', "App Store", {
                      {cons.act.launcher, 'App Store'}
                }},
            }
        },
    }

The above will configure two menus, the Main Menu which can be loaded with the hotkey "alt-space" and the Application Menu which it not bound to a hotkey but is accessible by pressing "A" in the main menu.

Customizing Menus

Menus are defined in the menuHammerMenuList table. Each menu can have the following values:

  • parentMenu - Optional. If set, MenuHammer will display a Back command to return to the parent menu. The value of parentMenu must match an identifier of another menu. E.g. to load the Applications menu defined above, the identifier must be exactly "applicationMenu".
  • menuHotkey - Optional. A hotkey for loading the menu. A hotkey is optional on menus but at least one must be set in order to load MenuHammer. Any menu that does not have a hotkey or is not linked to from another menu is unreachable.
  • menuItems - A table of menu items that will be shown in the menu.

Example of a basic menu configuration:

    mainMenu = {
        parentMenu = nil,                 -- The identifier of the parent menu.  Nil if no parent.
        menuHotkey = {{'alt'}, 'space'},  -- The hotkey that loads the menu.  Nil if no hotkey.
        menuItems =  {                    -- The menu items for this menu.
            <menu items go here>
        }
    }

Customizing Menu Items

Menu items are defined in the menuItems table for each menu. The values sent to them are:

  • category - Determines how to display the item. The background and text colors are chosen by the category. The "exit" category also closes the menu by default without requiring an action.
  • modifiers - The key modifiers (e.g. "alt", "cmd", "shift", "ctrl") to use for the hotkey for this menu item. If no modifiers are required, enter a blank string or nil.
  • key - Required field. The key to press in the menu to activate the menu item.
  • Description - The text to display to the user for this menu item.
  • Actions - A table of actions (outlined below) to perform when this menu item is activated.

Categories

Menu items have a category that are mostly used for formatting purposes. The only category that performs an action by default is the "exit" menu item which will always close the open menus. The category selected will determine what default colors are applied and what symbol is displayed as a prefix. Typically you will only need to use "submenu" and "action". You can use the cons.cat table to refer to specific categories. E.g. cons.cat.menu.

Sub Menu - cons.cat.submenu

This category is used when the menu item is for loading another menu.

For example, this menu item will load the Applications menu:

    {cons.cat.menu,                           -- Category is menu
     '',                                      -- No modifier
     'A',                                     -- "a" is the hotkey to open the menu
     'Applications',                          -- The description of the menu item to display
     {                                        -- The table of actions to perform
         {cons.act.menu, "applicationMenu"}  -- Action to open the Application menu
     }
    },

Action - cons.cat.action

This category is used when the menu item performs one or more actions. MenuHammer closes when actions are performed. MenuHammer will close the open menu when an action is performed, unless you specify true as the last argument.

For example, this menu item will launch the Terminal application, closing the menu immediately when the terminal is launched:

    {cons.cat.action,                        -- Category is action 
     '',                                     -- No modifier
     'T',                                    -- "t" is the hokey to activate the action
     "Terminal",                             -- The description of the action
     {                                       -- The table of actions to perform
         {cons.act.launcher, 'Terminal'}     -- Action to launch the Terminal application
     }
    },

And this one will increase the volume, without closing the menu:

    {cons.cat.action, '', 'K', "Volume Up 10%", {
         {cons.act.mediakey, "adjustVolume", 10}},
         true,
    },

Exit - cons.cat.display

This category is used to display data on the menu. It will display whatever text is returned from the function it is provided.

TODO: Currently, the function will block the menu from displaying until it completes but this should be fixed in the future.

TODO: The definition for display items requires a table to surround the function but this serves no purpose and should be fixed in the future.

For example, this definition will display "Hello" in the menu:

    {cons.cat.display,                       -- Category is display
     'MenuHammer Repo',                      -- A description (not displayed on the UI)
     {                                       -- A table that I just realized is unnecessary and I might remove.
         function()                          -- The function to execute to get the display value
             return "MH: " .. getGitStatus("~/code/MenuHammer", "master")
         end
     }
    },

Exit - cons.cat.exit

Used for menu items that close MenuHammer. There is an exit action defined by default on all menus that is bound to escape.

Back - cons.cat.back

Used for "back buttons" to go to the menu set as the parent menu to the current menu. There a back action defined by default on all menus that is bound to delete.

Navigation - cons.cat.navigation

A general category used for any nagivation item that isn't "exit" or "back". No menu items are defined by default with this category.

Actions

There are several types of actions that can be performed by menu items. Each menu item can perform a list of actions. You can use the cons.act table to refer to specific actions. E.g. cons.act.menu to load a menu.

Each action is defined as a table with an action type and a series of other values that are dependent on the action type.

Menu - cons.act.menu

This action loads the menu with the provided identifier.

Arguments:

  • Identifier - The identifier of the menu to load. If the menu identifier is not found in the menu table, it will cause an error.
    {cons.cat.menu, '', 'A', 'Applications', {
        {
            cons.act.menu,     -- Action type
            "applicationMenu"  -- Identifier
        }
    }},

Func - cons.act.func

This action will execute the provided function so it can be used to run other HammerSpoon or lua functionality.

Arguments:

  • Function - The function to execute when the menu item is activated.
    {cons.cat.action, 'shift', 'F', "Force Quit Frontmost App", {
        {
            cons.act.func,                                                -- Action type
