When copying and pasting content from Safari to Messages.app, all links are jarringly expanded, making the text hard to read: The best way to demonstrate the power of this module is through examples. Wouldn’t it be useful to have hotkeys bound in certain contexts or applications but not others? Organize windows and react to events on the basis of position, size, workflow, or any combination thereof? The extremely versatile hs.window.filter module allows this, enabling you to create complex window groupings and behaviors with filtering rules and event watchers. This may seem like a fairly complex set of options, but it’s worth spending some time learning, as it allows for extremely powerful window layouts, particularly in reaction to system events (such as the number of screens changing when you plug in a monitor, or even just press a particular hotkey to restore sanity to your windows). Note that we’re using the hs.geometry.rect() helper function to construct the rect table and that the y value is negative, meaning that the top of the window should start 48 pixels above the bottom of the display. This is shown in our example above, which will place the iTunes Mini Player window at the very bottom left of the screen, even if the dock is there. The sixth item is similar to the fifth, except it does take the OS menubar and dock into account. ![]() The fifth item is a rect that will be given to hs.window:setFrame() and should specify the position/size values as pixel positions on the screen, but without the OS menubar and dock taken into account.

Reply to this email directly or view it on GitHub. There are no errors in the log, it just seems that the handler stops at some point. Now I'm having the problem that the eventtap randomly stops working.

I'll look at the source later and see if its storing the eventtap in the registry or not. If that returns false, then its been stopped, but I'm not sure why since unless you request the stop explicitly (or it is garbage collected during a reload or Hammerspoon quitting) it should restart itself.Īctually, since you're not capturing the eventtap in a variable, it might be garbagecollection.
