"pragma once in main file" warning reported in header files #53

Open vittorioromeo opened 7 years ago

vittorioromeo commented 7 years ago

Even when #pragma once is used in an header file, the plugin incorrectly reports a diagnostic mentioning that it's being used in a main file. This issue has appeared (and has been fixed) in other editor plugins making use of clang. See:

A workaround would simply be to check the extension of the current fail and get rid of the diagnostic if it's an header.

Moreover, the files using these headers are marked as being affected as well in the explorer sidebar, and so on and so forth. This can easily spread over a significant part of the workspace, which is quite irritating.

After working for a while, lots of files are marked and I never know if these are "real" warnings or just pragma once virus spreading.

Looks like this has been sitting quite a while. Is there a way to at least disable this in the IDE?

You can disable the warning by setting "clang.cxxflags": ["-Wno-pragma-once-outside-header"]
