nim idetools --track:tc.nim,14,6 --def
I tried different switches but it's hard to know what might be wrong since it just seems to fail silently. nim_debug.exe at least returns an "index out of bounds" error, but I'm not sure what that refers to, since I've tried many different line/col combinations with no difference.
