Using hammerspoon and the spaces module to move window to new space - macos

Question

I have installed the "undocumented spaces" module from https://github.com/asmagill/hs._asm.undocumented.spaces. In particular, it provides a method moveWindowToSpace that I am trying to use to bind cmd+1 to move the the current window to space 1 using the following:
local spaces = require("hs._asm.undocumented.spaces")
function MoveWindowToSpace(sp)
local spaceID = spaces.query()[sp]
spaces.moveWindowToSpace(hs.window.focusedWindow():id(), spaceID)
spaces.changeToSpace(spaceID)
end
hs.hotkey.bind({"cmd"}, "1",function() MoveWindowToSpace(1) end)
This works in the sense that it moves the window to a new space, however, the spaces appear to be in a pseudo random order.
Does any one know how to correctly map spaceIDs, as returned by spaces.query(), to the actual spaces?

Answer 1

As undocumented spaces has moved to spaces, the new code would be as follows (some lines could be merged, but I like the clarity of splitting operations):
spaces = require("hs.spaces")
-- move current window to the space sp
function MoveWindowToSpace(sp)
local win = hs.window.focusedWindow() -- current window
local cur_screen = hs.screen.mainScreen()
local cur_screen_id = cur_screen:getUUID()
local all_spaces=spaces.allSpaces()
local spaceID = all_spaces[cur_screen_id][sp]
spaces.moveWindowToSpace(win:id(), spaceID)
spaces.gotoSpace(spaceID) -- follow window to new space
end
hs.hotkey.bind(hyper, '1', function() MoveWindowToSpace(1) end)
hs.hotkey.bind(hyper, '2', function() MoveWindowToSpace(2) end)
hs.hotkey.bind(hyper, '3', function() MoveWindowToSpace(3) end)

Answer 2

After some hints from the author of the spaces module I came up with the following, which seems to do the trick.
local spaces = require("hs._asm.undocumented.spaces")
-- move current window to the space sp
function MoveWindowToSpace(sp)
local win = hs.window.focusedWindow() -- current window
local uuid = win:screen():spacesUUID() -- uuid for current screen
local spaceID = spaces.layout()[uuid][sp] -- internal index for sp
spaces.moveWindowToSpace(win:id(), spaceID) -- move window to new space
spaces.changeToSpace(spaceID) -- follow window to new space
end
hs.hotkey.bind(hyper, '1', function() MoveWindowToSpace(1) end)
Previously I was using a variation on the code at https://github.com/Hammerspoon/hammerspoon/issues/235, which hooks into osx defined hotkeys for switching spaces, but the code above is much faster!

For those in 2020 looking for simpler working solution, you could use apple scripts:
function moveWindowOneSpace(direction)
local keyCode = direction == "left" and 123 or 124
return hs.osascript.applescript([[
tell application "System Events"
keystroke (key code ]] .. keyCode .. [[ using control down)
end tell
]])
end
I tried to use solutions from this issue, but it didn’t work. On the other hand apple scripts work like charm.
