pos_in_line is necessary because the cursor could be positioned like
this on the moment of pressing tab:
cp /var/lo[cursor] /home/foo
I thought passing the last "symbol" as convenience (in this example,
'/var/lo') could be handy, but it would bloat the hook too much.
I guess I'll pass a "Struct" object, where the hook would be:
print event.line, event.pos_in_line, event.symbol, event.command
(where 'command' would be the first word).
symbol and command are there purely for the convenience.
I think the completion hooks should be dispatchable by both of:
- Dictionary lookup with 'command' (for performance)
- Regexp (where the hooks with empty regexp are always tried).
