You can't really do this through torquescript, to really do it you gotta use an external program to attach to blockland on startup.
Client-sided or server-sided?
Huh? You can't detect anything from a client's console serverside, so obviously it's clientside. And either way, there's no TS callback for when things are printed to console, and testArrayCtrl.dump(); reveals no way to even grab text from the console.
I'm asking the OP. If it's server-sided, not possible. But there is definitely a callback on the console control for when a new line is added, I've had to use it before.
Badspot should make a callback for console output
I reckon it can be abusuable.
Please enlighten us then, because I just went looking for one and couldn't find one, and this is a very useful thing to have.
ConsoleEntry::eval
that's for when a command is put into the console, not when a line is output into the console.
