Paste text from hs.chooser in hammerspoon - lua

Question

I am trying to create a shortcut where I store a set of text templates by using hs.chooser. And, the user can paste this by clicking on the drop down from hs.chooser.
I use the below code which displays my template but doesn't paste the text.
Can someone point me what I am doing wrong?
hs.hotkey.bind({"Q"}, "W", function()
local current = hs.application.frontmostApplication()
local chooser = hs.chooser.new(function(choice)
if not choice then focusLastFocused(); return end
hs.pasteboard.setContents(choice["chars"])
focusLastFocused()
hs.eventtap.keyStrokes(hs.pasteboard.getContents())
end)
chooser:queryChangedCallback(function(string)
local choices = {
{
["text"] = "Testing",
["subText"] = "Testing my text"
}
}
chooser:choices(choices)
end)
chooser:searchSubText(true)
chooser:show()
end)

Answer 1

I figured out the answer
-- Focus the last used window.
local function focusLastFocused()
local wf = hs.window.filter
local lastFocused = wf.defaultCurrentSpace:getWindows(wf.sortByFocusedLast)
if #lastFocused > 0 then lastFocused[1]:focus() end
end
-- On selection, copy the text and type it into the focused application.
local chooser = hs.chooser.new(function(choice)
if not choice then focusLastFocused(); return end
hs.pasteboard.setContents(choice["subText"])
focusLastFocused()
hs.eventtap.keyStrokes(hs.pasteboard.getContents())
end)
chooser:choices({
{
["text"] = "Browser\n",
["subText"] = "I used these browsers",
},
{
["text"] = "Device\n",
["subText"] = "I used these devices",
},
})
hs.hotkey.bind({"E"}, "E", function() chooser:show() end)
