The first argument is + the text in the console. You can close the console from within the + callback by calling ``input.terminate()``. If you don't, the console + stays open and the user can input more text. + + ``opened`` + A callback invoked when the console is shown. This can be used to + present a list of options with ``input.set_log()``. + + ``edited`` + A callback invoked when the text changes. This can be used to filter a + list of options based on what the user typed with ``input.set_log()``, + like dmenu does. The first argument is the text in the console. + + ``complete`` + A callback invoked when the user presses TAB. The first argument is the + text before the cursor. The callback should return a table of the string + candidate completion values and the 1-based cursor position from which + the completion starts. console.lua will filter the suggestions beginning + with the the text between this position and the cursor, sort them + alphabetically, insert their longest common prefix, and show them when + there are multiple ones. + + ``closed`` + A callback invoked when the console is hidden, either because + ``input.terminate()`` was invoked from the other callbacks, or because + the user closed it with a key binding.
