`static: echo "compiling..." proc display[T](message: T) = when not (T is
string): {.fatal: "T is not a string".} echo message # works
display[string]("hello") # fatal error, compilation aborted # display[int](5) `
Run
The answer to my question in another thread lead to the answer to this one.
Replace the "compile error" line with:
static:
doAssert(false, "T is not a string")
Run
The the doAssert will run at compile time.
How do you gracefully stop the compiler? You can specify garbage to stop it,
but is there a better way?
static:
echo "compiling..."
proc display[T](message: T) =
when not (T is string):
compile error: "T is not a string"
