GPS/Gnat Studio: Code completion with other projects

GPS/Gnat Studio: Code completion with other projects

[John Perry]

Hi!

Suppose I've developed a package A, saved as a project. Now I'm working on package B. I make A available by specifying it in my gpr file, either as a with statement or by adding it to Source_Dirs. In package B I have the statement "with A;".

At this point, while I edit package B, Gnat Studio will code-complete any entity of package B, as well as any entity from the Ada standard library, but it won't code-complete entities from package A, such as A.Some_Feature.

How do I get Gnat Studio to do that?

thanks
john perry

It is a bug introduced in the latest version. Cross-referencing (it 
seems more than just auto-completion affected) across packages worked 
fine in earlier GPS versions.

Thank you very much. One place it fails for me is indeed the most recent Gnat Studio. However, I can't get it to work in a previous version, either, perhaps because I'm using the wrong method to include it. (GPS 2019, last one on Mac)

One thing I tried was

    with "path/to/package/A.gpr";
    project B is
        -- etc.

Another thing I tried was

    project B is
        for Source_Dir use ("src","path/to/package/src");
        -- etc.

Apparently neither of those does what I want. Does it look as if I am missing something?

You might try this ... 

To enable 'Find All References' => Append 'GPS.LSP.ADA_SUPPORT=no' to ~/.gnatstudio/traces.cfg

... it should help with finding references and refactoring.

What error message did this give?

You probably have to put the package directory in the environment variable
GPR_PROJECT_FILES.

Wow, that worked. Can you explain why? I don't see the connection at all. (I don't know what "GPS.LSP" means, either.)

...oddly, once I remove that file it still works. I know it wasn't working before; that's why I asked. Very confusing. I'll look into it more & report back.

I *think* it's "Language Server Plugin".
