[cmake-developers] C# support?

Thu Jul 2 09:53:44 EDT 2015

Hi all,

I got the first sort of working version running. Would be great if some people could have a look at it if it's going into a good direction.

Some explanations:

Patch 0001:
 - adds the necessary Module/* files for enabling C# as a language
 - CAUTION: only Visual Studio 2013 generators are supported at the moment
 - there is a verbose message which is shown when C# is used to guide people where to go for improvement

Patch 0002:
 - some minor changes to mostly visual studio related classes to enable .csproj support
   o .csproj GUID is added
   o a method to check if the target is C# is added

Patch 0003:
 - the actual implementation of the .csproj generation
 - all generation takes place inside VisualStudio10TargetGenerator class

There is an example project in the appendix of this mail which you can use to see how .csproj can be generated now.

And yes, there are still quite some things missing:

 - Tests (!!!!)
 - NMake support (even though that should not bee too hard)
   o better handling of the flagtable that I added (not sure if I understood correctly how the concept is supposed to be used)
 - documentation (!!!!)

Most questions on how to use the C# language and mixing with C++ targets should be answered by looking at the example project.

Some VS_* target properties already existed which I reused.

I added two Property-"Groups":
 - VS_DOTNET_REFERENCE_<NAME>        properties for references with a <Hint> tag, though they 
                                     also can be added to the normal VS_DOTNET_REFERENCES. This is
                                     a target-property
 - CSharpPROJ_<name>                 the tag <name> will be added to the <Compile> tag of the specified
                                     Source files. This is a source property.
 - CSharpPROJ_SubType                the currently only used case of above property group. It's needed
                                     to tell visual studio what kind of file is added. You can safely omit
                                     this, but visual studio will not be able to run the designer in the
                                     correct mode without it.

Project references are added by simply using target_link_libraries(). All other references must use done in one of the above described ways.

It would be great if some people could try if the example project works for them. If you have improvements don't hesitate to submit any patch to my current fork on github (branch "csharp"):

https://github.com/micst/CMake.git

The example project can be found there as well:

Michael
