![]() Local selection = currentElement : attributeValue ( "AXSelectedTextRange" ) and `loc` is where the cursor currently is in the text, between `` where `len` is the length of the current selection (0 if no text is selected) Local textLength = currentElement : attributeValue ( "AXNumberOfCharacters" ) Local value = currentElement : attributeValue ( "AXValue" ) You can ask it for the current value, length, and selection range: local systemElement = ax. Local currentElement = systemElement : attributeValue ( "AXFocusedUIElement" ) You can easily grab the currently focused input field: local systemElement = ax. To use it, follow the install instructions and require it in your scripts: local ax = require ( "hs._asm.axuielement" ) You can get cursor position, selection range, the value of the field, and even character index ranges for each wrapped line in a multi-line input, which helps when doing things like linewise Vim has written an awesome library for interacting with the Accessibility API from Hammerspoon called hs._asm.axuielement, which I’ve made extensive use of. Mac’s Accessibility API is really awesome, and in the best case, exposes more data than you could ever need about the currently focused input field. If anyone has any other clever ideas or techniques, I would really love to hear about them–please email me at and we can chat! The Accessibility API: almost perfect # Trying to work around when the Accessibility API fails to get a cursor position.Using the MacOS Accessibility API, and caveats/hacks.I’ve tried a number of different ways to achieve this, and I want to document those experiments here, along with the pros and cons. Mode to every input in the Mac operating system.Ī big part of this library’s success is being able to read the current value and cursor position of the currently focused input field from Hammerspoon. In my spare time, I work on a library called Can we get around the Electron selection problem?.Lots of people! You can find out more on our Contributors page.Retrieving input field values and cursor position/selection with Hammerspoon If you find a bug, or have a suggestion, you can also file an issue on the issue tracker. You can usually get a quick answer in our IRC channel, #hammerspoon on Libera. For more information, see the contribution guidelines on GitHub.īugs found on can be reported on GitHub Where can I get help? They can either be pure Lua scripts that offer useful helper functions, or you can write Objective-C extensions to expose new areas of system functionality to users. More extensions will always be a huge benefit to Hammerspoon. You can learn more about the Lua scripting language at lua.org. If you are new to Hammerspoon, read the Getting Started Guide with reference to the full API documentation. You will need to create a Lua script in ~/.hammerspoon/a using our APIs and standard Lua APIs. Out of the box, Hammerspoon does nothing. If you are using an older Mac which is not running a recent version of macOS, please consult our Release Notes for a version which is compatible with your system. How do I install it?ĭownload the latest release and then drag the application to /Applications/. You might want to do something crazy like have iTunes automatically start playing when your Mac detects you are in Paris. ![]() You might want to display an alert when your battery drops below a certain percentage. You might want to run a series of commands when your wifi interface connects to your home network. You might want to bind a keyboard shortcut to a series of window operations, or an applescript. Typically you would write a configuration file in Lua that connects events to actions. If you want to explore the options Hammerspoon offers, check out the Getting Started Guide and the full API documentation as well as the already pre-made plugins called Spoons. You can write Lua code that interacts with macOS APIs for applications, windows, mouse pointers, filesystem objects, audio devices, batteries, screens, low-level keyboard/mouse events, clipboards, location services, wifi, and more. What gives Hammerspoon its power is a set of extensions that expose specific pieces of system functionality, to the user. At its core, Hammerspoon is just a bridge between the operating system and a Lua scripting engine. This is a tool for powerful automation of macOS.
