How can I modify <<ExternLibrary>> std? [message #1835199]

I was wondering if it is possible to modify the <<ExternLibrary>> std because I need to work with std::thread and it is not contained in it.

You can't. Libraries deployed in bundles in the Eclipse/Papyrus workbench are read-only resources.

But you can create your own library with the types you need, to share them amongst your design models. Only I don't know what would be the semantics of importing multiple distinct packages named 'std'. Probably for code generation it wouldn't matter.

HTH,

Well, that sucks. I was fearing I would have to do that.

Yeah, it's only for code generation. Do you know how can I create my own library? Is that process just as a regular project?

A model library is just a package that contains reusable constructs meant to be imported into/referenced by your models. So, yeah, the very same process.

You might choose to stereotype your library package as «ModelLibrary» for documentation purposes; maybe some tools would treat it specially, I don't know.

... or you create a bug for Papyrus SW designer with the lists of elements missing for you in the C++ std library. Of course, are lot are missing as the C++ library is huge. Thus, I don't aim for a complete library, but it would be good if the likelihood to find relevant classes inside becomes a bit bigger.

Well, I could do that, but that means I would be creating a lot of bugs and I don't think that you should use your time on adding stuff to std when you can use it for more valuable activities like fixing real issues.

I will just create my own std and add stuff as I need it. I just thought it was a way of modifying the included one myself, hence the question in the original post.
