Hammerspoon: hs.window.focusedWindow() returns nil

[tornikenats]

I am using Hammerspoon as a window manager. I have shortcuts that put the window in each corner.

Initially everything works. However, sometimes after sleep/waking the computer .focusedWindow() starts returning nil for specific applications.

Finding the window with hs.window.allWindows() and doing .focus() on it works. However, focusedWindow() still returns nil.

I am having this issue for PyCharm.

note: I have seen comments that Hammerspoon doesn't work on X11 apps but I don't think PyCharm is X11.

Jetbrains apps seem to do weird things with windows - see here: https://github.com/Hammerspoon/hammerspoon/issues/736#issuecomment-184962738

Someone will need to breakpoint/debug the focusedWindow method when using IntelliJ/PyCharm.

it's not just X11 apps - anything that entirely avoids the OSX accessibility stuff is very hard to interact with. What does hs.window.frontmostWindow() do?

[tornikenats]

If you manualy get the window with pid (getApplication) then you can set the frame without issue.

I have the same problem. Window's moving hotkeys work with hammerspoon's console only.
And I also can't enable accessibility for hammerspoon app. Dot becomes yellow every time I quit hs.
But green one doesn't make window's functions work.
sudo sqlite3 /Library/Application Support/com.apple.TCC/TCC.db 'select * from access where client like "%hammerspoon%"'
gives me " kTCCServiceAccessibility|org.hammerspoon.Hammerspoon|0|0|1|| "
I have 0.9.45 hs version and os 10.11.4

Can anyone try whether using a "focused" windowfilter works around the problem?

focusedwf=hs.window.filter.new{default={focused=true}}:keepActive()
[...]
function f(...)
  --local w=hs.window.focusedWindow() --instead:
  local w=focusedwf:getWindows()[1]
  [...]
end

It doesn't work for me
focusedwf=hs.window.filter.new{default={focused=true}}:
function nudgeRight()
--local win = hs.window.focusedWindow()
local win = focusedwf:getWindows()[1]
local f = win:frame()
saved.win = win
saved.winframe = saved.win:frame()
f.x = f.x + 10
win:setFrame(f)
end

now "attempt to index a nil value (local 'win')" is in "local f = win:frame()"

I see this every time I first launch hammerspoon. If I don't focus a window after launching, hs.window.focusedWindow() returns nil.

[woodpeckeroloco]

I reinstalled OS. No problems with accessibility now and windows movement work fine.

I see this every time I first launch hammerspoon. If I don't focus a window after launching, hs.window.focusedWindow() returns nil.

I wonder if that's related to #651?

[cmsj]

@chdiza That was my thought too

I'm trying to clean up our list of issues. This one hasn't had any activity for a year, so I'm going to close it. Please re-open, or file a new issue if you are experiencing this specific issue.

osx: hs.window.focusedWindow() returns with nil until has not given right in system preferences/security/accessibility/privacy
