Please change SDK header fiels to contain #pragma once at start of file

Hi,

could you please in a following release foresee all headers of a #pragma once statement at the beginning of the header file?

I know this is probably not needed for the way you develop code, but we have other best practices and it would make life a lot easier. It doesn't hurt either for your way of working, and, it is a common practice.

Thx

Wim

Sorry this contradicts our best practises, so we won't change that.

Maybe consider header guards, which are for sure a common practice in C++ development and not compiler dependent:

https://google.github.io/styleguide/cppguide.html#The__define_Guard

https://rules.sonarsource.com/c/tag/unpredictable/RSPEC-5259

Anyway, we worked around the issue to avoid the massive amount of redefinition errors one quickly gets without one of these. Other people that might encounter same issue can quickly construct an innovaphone.h file in their project with following content:

#pragma once

//Important: order does matter!

#include "platform/platform.h"
#include "common/os/iomux.h"
#include "common/interface/task.h"
#include "common/interface/socket.h"
#include "common/interface/webserver_plugin.h"
#include "common/interface/database.h"
#include "common/interface/json_api.h"
#include "common/ilib/str.h"
#include "common/ilib/json.h"
#include "common/interface/random.h"
#include "common/interface/pbx_admin.h"
#include "common/lib/appservice.h"
#include "common/lib/config.h"
#include "common/lib/tasks_postgresql.h"
#include "common/lib/appwebsocket.h"
#include "common/lib/app_updates.h"
#include "common/lib/badgecount_signaling.h"

After that, just use #include innovaphone.h which makes life easier.

Anyway, just something that would make life easier... case closed.

Yes you can solve it this way. We believe in well maintained include statements, which actually provide information about dependencies.
