Compiler SyntaxError

[ahopkins]

It would be helpful to add a catch for SyntaxError in the compiler to output the source. Something like this, except abstracted so that line numbers and source can be displayed in other uses as well:

            try:
                compiled_src = compile(
                    self.find_route_src,
                    "",
                    "exec",
                )
            except SyntaxError as e:
                lines = self.find_route_src.split("\n")
                pad = len(str(len(lines)))
                logger.error(
                    "\n".join(
                        f"{str(idx+1).rjust(pad)}: {line}"
                        for idx, line in enumerate(lines)
                    )
                )
                raise e
