How do I get/process input?
Construct the real time input struct outside your loop then use
getch if you're only interested in the core keyboard ascii
stuff or nextEvent if you want everything.
The esc key, in particular, is considered a non-character key
event by terminal.d, so it will not be there on a simple call
to getch(). (this might have been a mistake but is the way it
is)
Search the code for "void handleEvent" to see an example
function. There's various event types you can react to and to
get the info, you do
auto specialized_event =
generic_event.get!(InputEvent.Type.TYPE HERE);
and look at the members. character event has ev.character.
noncharacter event has ev.key which is an enum, defined on line
2057.
PasteEvent doesn't work perfectly so dont' rely on it.
MouseEvent, if you opt into them, has buttons, x, y, and
modifierState which might be available.
See the source for each struct to see more.
If you're happy with keys from the middle part of the keyboard,
getch is the easiest way though, they are sent as simple dchars.
You can also fetch lines at a time with terminal.getline (it is
on terminal rather than real time input because it is still
conceptually line buffered (though the implementation turns
that off to allow editing)).
Perfect, thank you again for a thorough answer.
