If I'm gonna write RAII wrappers around every tiny little thing that I happen to need to call once... I might as well just use Rust and make the wrappers do FFI.
If I'm constructing a particular C object once in my entire code base, calling a couple functions on it, then freeing it, I'm not much more likely to get it right in the RAII wrapper than in the one place in my code base I do it manually. At least if I have tools like defer to help me.
- feelamee 9mo agoif you do it once - why do you care about "ugly" scope_exit? btw, writing such wrappers is easy and does not require a lot of code.
- mort96 9mo agoWhat do you mean with '"ugly" scope_exit'? Do you mean why I care that I have to call the free function at every exit point of the scope? That's easy: because it's error prone. Defer is much less error prone.
- feelamee 8mo agoyour words... > C++ implementations of defer are either really ugly I agree with @pjmlp - you need to write wrappers around the C api. But if you.. > If I'm gonna write RAII wrappers around every tiny little thing that I happen to need to call once use them just once.. so, why care about ugliness, just write ugly code just once? Code can't be perfect.
