FWIW, I'm in favor of the patch as it sits.
As a followup: So I was thinking about the "%s" specifier for string types.
Assuming char-ptr types are all strings is a LITTLE dangerous, but more so the
way we're doing it. Its a shame we don't have some way of setting a 'max'
limit to the number of characters we have for 2 reasons:
1- For safety: If the char-ptr points to non-null-terminated memory, it'll stop
us from just arbitrarily printing into space by limiting at least the NUMBER of
characters we print into nonsense.
2- For readability: printing a 'long' string likely makes this output look like
nonsense and breaks everything up. Limiting us to only a few characters is
likely a good idea.
3- <Bonus #3 from @aaron.ballman >: It might discourage SOME level of attempts
at using this for reflection, or at least make it a little harder.
What I would love would be for something like a 10 char max:
struct S {
char *C;
};
S s { "The Rest of this string is cut off"};
print as:
struct U20A a = {
.c = 0x1234 "The Rest o"
};
Sadly, I don't see something like that in printf specifiers? Unless someone
smarter than me can come up with some trickery. PERHAPS have the max-limit
compile-time configurable, but I don't feel strongly.
