isnumber() is not a function in that library. What he likely meant is isdigit().

Thank you for the reporting this. Yes, I'm interested.
I recommend you try the newest version of Nymph.

It looks like ctype.h should include isnumber(), but doesn't. I am running gcc 6.3.0 on Debian 9.0 (Stretch) for the above output. Clang outputs a similar error message during the linking step. Do I need to use a different compilation command?

@roecrew The latest commit fixes this issue. Thanks.
