This submodule allows hs.axuielement to support using AXTextMarker and AXTextMarkerRange objects as parameters for parameterized Accessibility attributes with applications that support them.
Most Accessibility object values correspond to the common data types found in most programming languages -- strings, numbers, tables (arrays and dictionaries), etc. AXTextMarker and AXTextMarkerRange types are application specific and do not have a direct mapping to a simple data type. The description I've found most apt comes from comments within the Chromium source for the Mac version of their browser:
// A serialization of a position as POD. Not for sharing on disk or sharing // across thread or process boundaries, just for passing a position to an // API that works with positions as opaque objects.
This submodule allows Lua to represent these as userdata which can be passed in to parameterized attributes for the application from which they were retrieved. Examples are expected to be added to the Hammerspoon wiki soon.
As this submodule utilizes private and undocumented functions in the HIServices framework, if you receive an error using any of these functions or methods indicating an undefined CF function (the function or method will return nil and a string of the format "CF function AX... undefined"), please make sure to include the output of the following in any issue you submit to the Hammerspoon github page (enter these into the Hammerspoon console):
