Filter windows by application, title, location on screen and more, and easily subscribe to events on these windows
Warning: this module is still somewhat experimental.
Should you encounter any issues, please feel free to report them on https://github.com/Hammerspoon/hammerspoon/issues
or #hammerspoon on irc.freenode.net
Windowfilters monitor all windows as they're created, closed, moved etc., and select some (or none) among these windows
according to specific filtering rules. These filtering rules are app-specific, i.e. they start off by selecting all windows
belonging to a certain application (but you can also define default and override filters - see :setAppFilter()
,
:setDefaultFilter()
, :setOverrideFilter()
) and they can allow or reject windows based on:
- visibility, focused and/or fullscreen status
- title length or patterns in the title
- position on screen (inside or outside a certain region or screen)
- accessibility role (standard window, dialog, etc.)
- whether they're in the current Mission Control Space or not
The filtering happens automatically in the background; windowfilters then:
- generate a dynamic list of the windows that currently satisfy the filtering rules (see
:getWindows()
)
- sanitize and expose all pertinent events on these windows (see
:subscribe()
and the module constants with all the events)
A default windowfilter (not to be confused with the default filter within a windowfilter) is provided as convenience;
it excludes some known apps and windows that are transient in nature, therefore unlikely to be "interesting" for e.g. window management.
hs.window.filter.new()
(with no arguments) returns a copy of the default windowfilter that you can further tailor
to your needs - see hs.window.filter.default
and hs.window.filter.new()
for more information.
Usage examples:
local wf=hs.window.filter
-- alter the default windowfilter
wf.default:setAppFilter('My IDE',{allowTitles=1}) -- ignore no-title windows (e.g. transient autocomplete suggestions) in My IDE
-- set the exact scope of what you're interested in - see hs.window.filter:setAppFilter()
wf_terminal = wf.new{'Terminal','iTerm2'} -- all visible terminal windows
wf_timewaster = wf.new(false):setAppFilter('Safari',{allowTitles='reddit'}) -- any Safari windows with "reddit" anywhere in the title
wf_leftscreen = wf.new{override={visible=true,fullscreen=false,allowScreens='-1,0',currentSpace=true}}
-- all visible and non-fullscreen windows that are on the screen to the left of the primary screen in the current Space
wf_editors_righthalf = wf.new{'TextEdit','Sublime Text','BBEdit'}:setRegions(hs.screen.primaryScreen():fromUnitRect'0.5,0/1,1')
-- text editor windows that are on the right half of the primary screen
wf_bigwindows = wf.new(function(w)return w:frame().area>3000000 end) -- only very large windows
wf_notif = wf.new{['Notification Center']={allowRoles='AXNotificationCenterAlert'}} -- notification center alerts
-- subscribe to events
wf_terminal:subscribe(wf.windowFocused,some_fn) -- run a function whenever a terminal window is focused
wf_timewaster:subscribe(wf.hasWindow,startAnnoyingMe):subscribe(wf.hasNoWindows,stopAnnoyingMe) -- fight procrastination :)

hs.window.filter.default |
Type |
Constant |
Description |
The default windowfilter; it filters apps whose windows are transient in nature so that you're unlikely (and often |
Notes |
- While you can customize the default windowfilter, it's usually advisable to make your customizations on a local copy via
mywf=hs.window.filter.new() ; - the default windowfilter can potentially be used in several Hammerspoon modules and changing it might have unintended consequences.
- Common customizations:
- to exclude fullscreen windows:
nofs_wf=hs.window.filter.new():setOverrideFilter{fullscreen=false} - to include invisible windows:
inv_wf=windowfilter.new():setDefaultFilter{} - If you still want to alter the default windowfilter:
- you should probably apply your customizations at the top of your
init.lua , or at any rate before instantiating any other windowfilter; this - way copies created via
hs.window.filter.new(nil,...) will inherit your modifications - to list the known exclusions:
hs.inspect(hs.window.filter.default:getFilters()) from the console - to add an exclusion:
hs.window.filter.default:rejectApp'Cool New Launcher' - to add an app-specific rule:
hs.window.filter.default:setAppFilter('My IDE',1) ; ignore tooltips/code completion (empty title) in My IDE - to remove an exclusion (e.g. if you want to have access to Spotlight windows):
hs.window.filter.default:allowApp'Spotlight' ; - for specialized uses you can make a specific windowfilter with
myfilter=hs.window.filter.new'Spotlight'

hs.window.filter.allowedWindowRoles |
Type |
Variable |
Description |
A table for window roles (as per hs.window:subrole() ) that are allowed by default. |
Notes |
- You can have fine grained control of allowed window roles via the
setAppFilter , setDefaultFilter , setOverrideFilter methods. - If you know what you're doing you can override the allowed window roles globally by changing this variable, but this is discouraged.
|
Signature |
hs.window.filter.forceRefreshOnSpaceChange |
Type |
Variable |
Description |
Tells all windowfilters whether to refresh all windows when the user switches to a different Mission Control Space. |
Notes |
- If you defined one or more Spaces-aware windowfilters (i.e. when the

Notes |
- As the name implies, even the empty, "allow all" windowfilter will ignore these apps.
- You don't need to keep this table up to date, since non GUI apps will simply never show up anywhere; this table is just used as a "root" filter to gain a (very small) performance improvement.

Returns |
|
Notes |
- Only use this function if "Displays have separate Spaces" and "Automatically rearrange Spaces" are OFF in System Preferences>Mission Control
- Calling this function will set

filter - Spaces-aware windowfilters might experience a (sometimes significant) delay after every Space switch, since (due to OS X limitations) they must re-query for the list of all windows in the current Space every time.
- If System Preferences>Mission Control>Displays have separate Spaces is on, the current Space is defined as the union of all the Spaces that are currently visible
- This table explains the effects of different combinations of
visible and currentSpace , showing which windows will be allowed: - ```

filters will overwrite the pre-existing one for the relevant application, if present; - this also applies to the special default and override filters, if included
|
Signature |
hs.window.filter:setOverrideFilter(filter) -> hs.window.filter object |
Type |
Method |
Description |
Set overriding filtering rules that will be applied for all apps before any app-specific rules |
Parameters |
- filter - see
hs.window.filter:setAppFilter
|
Returns |
- the
hs.window.filter object for method chaining
|
Signature |
hs.window.filter:setRegions(regions) -> hs.window.filter object |
Type |
Method |
Description |
Sets the allowed screen regions for this windowfilter |
Parameters |
- regions - an
hs.geometry rect or constructor argument, or a list of them, indicating the allowed region(s) for this windowfilter
|
Returns |
- the
hs.window.filter object for method chaining
|
Notes |
- This is just a convenience wrapper for setting the
allowRegions field in the override filter (other fields will be left untouched); per-app filters will maintain their allowRegions and rejectRegions fields, if present
|
Signature |
hs.window.filter:setScreens(screens) -> hs.window.filter object |
Type |
Method |
Description |
Sets the allowed screens for this windowfilter |
Parameters |
- regions - a valid argument for
hs.screen.find() , or a list of them, indicating the allowed screen(s) for this windowfilter
|
Returns |
- the
hs.window.filter object for method chaining
|
Notes |
- This is just a convenience wrapper for setting the
allowScreens field in the override filter (other - fields will be left untouched); per-app filters will maintain their
allowScreens and rejectScreens fields, if present
|
Signature |
hs.window.filter:setSortOrder(sortOrder) -> hs.window.filter object |
Type |
Method |
Description |
Sets the sort order for this windowfilter's :getWindows() method |
Parameters |
- sortOrder - one of the
hs.window.filter.sortBy... constants
|
Returns |
- the
hs.window.filter object for method chaining
|
Notes |
- The default sort order for all windowfilters (that is, until changed by this method) is
hs.window.filter.sortByFocusedLast
|
Signature |
hs.window.filter:subscribe(event, fn[, immediate]) -> hs.window.filter object |
Type |
Method |
Description |
Subscribe to one or more events on the allowed windows |
Parameters |
- event - string or list of strings, the event(s) to subscribe to (see the
hs.window.filter constants); alternatively, this can be a map {event1=fn1,event2=fn2,...} : fnN will be subscribed to eventN, and the parameter fn will be ignored - fn - function or list of functions, the callback(s) to add for the event(s); each will be passed 3 parameters
- a
hs.window object referring to the event's window - a string containing the application name (
window:application():name() ) for convenience - a string containing the event that caused the callback, i.e. (one of) the event(s) you subscribed to
- immediate - (optional) if
true , also call all the callbacks immediately for windows that satisfy the event(s) criteria
|
Returns |
- the
hs.window.filter object for method chaining
|
Notes |
- Passing lists means that all the
fn s will be called when any of the event s fires, so it's not a shortcut for subscribing distinct callbacks to distinct events; use a map or chained :subscribe calls for that. - Use caution with
immediate : if for example you're subscribing to hs.window.filter.windowUnfocused , fn (s) will be called for all the windows except the currently focused one. - If the windowfilter was paused with
hs.window.filter:pause() , calling this will resume it.
|
Signature |
hs.window.filter:unsubscribe([event][, fn]) -> hs.window.filter object |
Type |
Method |
Description |
Removes one or more event subscriptions |
Parameters |
- event - string or list of strings, the event(s) to unsubscribe; if omitted,
fn (s) will be unsubscribed from all events; - alternatively, this can be a map
{event1=fn1,event2=fn2,...} : fnN will be unsubscribed from eventN, and the parameter fn will be ignored - fn - function or list of functions, the callback(s) to remove; if omitted, all callbacks will be unsubscribed from
event (s)
|
Returns |
- the
hs.window.filter object for method chaining
|
Notes |
- You must pass at least one of
event or fn - If calling this on the default (or any other shared use) windowfilter, do not pass events, as that would remove
- all the callbacks for the events including ones subscribed elsewhere that you might not be aware of. You should
- instead keep references to your functions and pass in those.
|
Signature |
hs.window.filter:unsubscribeAll() -> hs.window.filter object |
Type |
Method |
Description |
Removes all event subscriptions |
Parameters |
|
Returns |
- the
hs.window.filter object for method chaining
|
Notes |
- You should not use this on the default windowfilter or other shared-use windowfilters
|
Signature |
hs.window.filter:windowsToEast(window, frontmost, strict) -> list of hs.window objects |
Type |
Method |
Description |
Gets all visible windows allowed by this windowfilter that lie to the east a given window |
Parameters |
- window - (optional) an
hs.window object; if nil, hs.window.frontmostWindow() will be used - frontmost - (optional) boolean, if true unoccluded windows will be placed before occluded ones in the result list
- strict - (optional) boolean, if true only consider windows at an angle between 45° and -45° on the
- eastward axis
|
Returns |
- A list of
hs.window objects representing all windows positioned east (i.e. right) of the window, in ascending order of distance
|
Notes |
- This is a convenience wrapper that returns
hs.window.windowsToEast(window,self:getWindows(),...) - You'll likely want to add
:setCurrentSpace(true) to the windowfilter used for this method call (or just use -
hs.window.filter.defaultCurrentSpace )
|
Signature |
hs.window.filter:windowsToNorth(window, frontmost, strict) -> list of hs.window objects |
Type |
Method |

- northward axis
|
Returns |
- A list of
hs.window objects representing all windows positioned north (i.e. up) of the window, in ascending order of distance
|
Notes |
- This is a convenience wrapper that returns
hs.window.windowsToNorth(window,self:getWindows(),...) - You'll likely want to add
:setCurrentSpace(true) to the windowfilter used for this method call (or just use -
hs.window.filter.defaultCurrentSpace )
|

- southward axis
|
Returns |
- A list of
hs.window objects representing all windows positioned south (i.e. down) of the window, in ascending order of distance
|
Notes |
- This is a convenience wrapper that returns
hs.window.windowsToSouth(window,self:getWindows(),...) - You'll likely want to add
:setCurrentSpace(true) to the windowfilter used for this method call (or just use -
hs.window.filter.defaultCurrentSpace )
|
Signature |
hs.window.filter:windowsToWest(window, frontmost, strict) -> list of hs.window objects |
Type |
Method |
Description |
