Almost all of my programs are in the following pattern:
import std.stdio;
void main(string[] args) {
version (unittest) {
// Don't execute the main program when unit testing
return;
}
try {
// Dispatch to the actual "main" function
doIt(args);
} catch (Exception exc) {
// Note .msg because we don't want to print stack trace
stderr.writefln!"ERROR: %s"(exc.msg);
} catch (Error err) {
// Note NO .msg because we DO want to print stack trace
stderr.writefln!"ERROR: %s"(err);
}
}
// This is the actual "main"
void doIt(string[] args) {
// ...
}
