Reading the documentation for aug_defvar it seems that I was wrong about how that works. It parses and evaluates the path parameter. However it would be nice to make this work, so I propose: aug_defconst (aug, const char *name, const char *value); Instead of evaluating the 'value', this would simply add (name, T_STRING value) to aug->symtab, thus doing no parsing and requiring no escaping. I'll see if I can implement something like this and if it works ...
