With the enum:
(.h)
enum advice_type {
ADVICE_FOO,
ADVICE_BAR
};
(.c)
static const char *advice_config_keys[] = {
[ADVICE_FOO] = "advice.foo",
[ADVICE_BAR] = "advice.bar"
};
/* No need for all_advice_type because we can loop over advice_config_keys */
With the bunch of variables of type const char []:
(.h)
extern const char ADVICE_FOO[];
extern const char ADVICE_BAR[];
(.c)
const char ADVICE_FOO[] = "advice.foo";
const char ADVICE_BAR[] = "advice.bar";
static const char *all_advice_type[] = {
ADVICE_FOO,
ADVICE_BAR
};
Junio, is this what you meant? It seems to me that there is an extra array to
be managed in the latter case. Admittedly, this is a tradeoff against needing
to convert the enum to a string when checking config, as you describe [1].
