Hi Fabien,

Thanks for the suggestions.

Can you please be clearer about which files or folders you want to be relative?

The sketch/Visual Micro can be excluded from source control. It is an auto generated file.

Library and Arduino core paths should auto refresh when the project is opened or certain events happen such as change board?

The C++ project properties are auto refreshed when a project is opened or certain events happen such as change board?

So is your question only about the .ino, cpp and .h sketch sources?

I need help to understand exactly the problem?

thanks

Hi Fabien.

The properties of the cppproj are not used for Arduino build, only for intellisense. Visual Micro also updates these properties when an Arduino sketch/project is opened (or it's a bug if this does not happen)

When an Arduino project is opened Visual Micro will also add any .ino/cpp/c/h sources that exist in the project/sketch folder but do not exist in the project. The reason being is that an Arduino in it's purest form does not need or know anything about Visual Studio. 

At all times, all of the properties/sources used by visual studio and/or the build/upload process are deduced from the physical files of the current sketch and also of the selected arduino core/libraries. The information in the cppproj is irrelevant to everything except the intellisense of the local visual studio sketch.

This complete separation from Visual Studio ensures that the source code of the sketch can be opened and compiled in the Arduino IDE just as it can in Visual Studio with Visual Micro.

So my question is now to understand where this becomes a problem. 

The vs locations should be re-written when each user uses Visual Micro so it would be useful to know what error you are seeing and at what stage in the checkin/checkout process?

Thanks

If your source control monitor works on a files & folder basis with auto discovery then I think it makes sense for Arduino to be without proj files.

It also means the source control has a very clean Arduino project (without Visual Studio or Visual Micro)

Yes if you want to work outside of a standard Arduino project you need the proj.

We will try to include this in the next release. 

In the meantime you could create a custom boards.txt entry in sketchbook/hardware/... (documents/arduino/hardware) and add your own boards.txt entry with the options you require. Then you will not need to use the pre-processor defines in the sketch project

The result will be a unique board of your own in the boards list that includes your additional defines. You can then create a cpp project that only includes the boards.txt you have created for source control.
