Stops the program with a message when arg is false. message can hold % markers filled from args, the same way
print does. The failure goes through context.assertion_failed, which prints the location and a stack trace and exits by
default.
assert :: (arg: bool, message := "", args: ..Any, loc := #caller_location)
Asserts are compiled out when Basic is imported with ENABLE_ASSERT = false, and the arguments are not evaluated then.
Parameters
- arg: bool
- message := ""
- args: ..Any
- loc := #caller_location
count := 3;
assert(count > 0, "count must be positive, got %", count);This one is only checked to compile, not run.
assert :: (arg: bool, message := "", args: ..Any, loc := #caller_location)
Parameters
- arg: bool
- message := ""
- args: ..Any
- loc := #caller_location
