With this Windows program you can intercept and generate keyboard events with a Lua script.
- Edit the script.lua file for your application
The demo script expects a consecutive 56 digits number from a barcode scanner for Australian Post 2D barcode, which is consumed by the script, and then extracts the tracking number, which is sent as new key events to the program which is in focus.
- Start the LuaKeyboardHelper program
You should see a minimal Windows program with a File and Help menu. As long as this program is running, the Lua script is running as well. The LuaKeyboardHelper.exe file and the script.lua file must be in the same directory.
In the Lua script, you have to define the function onKeyPressed and onKeyReleased, which are called when a key is pressed or released. From the script you can call the timeout function, which causes the onTimeout function to be called after the specified number of milliseconds. If you want to simulate a key press / release sequence, you can call the sendKey function, with the ASCII code of the desired key.
Install Visual Studi 2017 or later, open the LuaKeyboardHelper.sln project file, and build as usual. Tested for the 32 bit target.
