Dear Lazyweb,

Is there a more modern, GLib'ish version of gperf? I want to go from string->enum and emun->string faster than just using strcmp in a loop. I don't think I want to use GHashTable as it needs to be bi-directional. I like nice compact simple C code, and don't like awk in makefiles. Ideas?

Why reinvent the wheel? Is it really /that/ important to have a dependency on glib?

I've used an array of interned string pointers before for this sort of thing. enum->string is O(1) (array index lookup), string->enum is O(n) (compare string pointers for equality) plus a hash table lookup when calling g_intern_string() on the input string. The downside is you have to initialize the array at runtime.
