Title: GCC warnings
Post by: TheWaffle on November 29, 2018, 03:37:55 AM

I am playing with GCC's warnings, and I haven't been able to figure out how to suppress some of them.

The most annoying warning I enabled is with -Wshadow.
https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html (https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html)

I learned this pattern:

Code: [Select]

Person::Person(string name)
{
this->name = name;
My shadowing in the constructor is intentional. I do this a lot.  Is there a way to suppress the warning:

Quote

declaration of ‘name’ shadows a member of ‘Person’

on a case by case basis? Maybe with a macro? How do you guys do it?
I know a lot of people would do something like

Code: [Select]

this->myName = namebut I find the extra 'my' cringy. I don't know why I don't like it. I just don't.

rules for Wshadow have been changing in response to complaints from devs -
