Trying to create it as a global tries to make it as a static
variable which means it constructs at compile time. It can't
access the TERM environment variable at compile time and that
causes the error.
Putting Terminal at global scope isn't really ideal, there'd be
potential destructor problems (the terminal needs to be cleaned
up at program termination). You could stick a pointer to it up
there though:
Terminal* terminal; // maybe make it shared too but i'd try to
avoid that, terminal isn't quite thread safe
void main() {
auto main_terminal = Terminal(options...);
terminal = &main_terminal;
scope(exit) terminal = null; // clean up the pointer too
when it goes invalid
// the rest of your program goes normally
// and other functions can use the global pointer
}
Just make sure you set it in main before doing anything else so
the pointer isn't null and you should be good to go. Then when
main returns, it will clean up.
I see, thanks once again :D I don't know why the environment
variable isn't accessible at compilation (from a terminal) but
that's OS business I guess rather than D related.
I did try something similar to your solution but not using a
pointer - I'd prefer to avoid using pointers if at all possible!
