Print database in newer scheme

[LKlemens]

I am asking for support of newer scheme in compile_commands.json For instance:

{
        "arguments": [
            "c++",
            "-c",
            "TestMain.hpp"
        ],
        "directory": "/home/user/test",
        "file": "TestMain.hpp"
 }

Newer clang versions do not support scheme with "command" ;/ LIBCLANG TOOLING ERROR: json-compilation-database: Expected array.

Thanks in advance!

If you replace manually:

        "arguments": [
            "c++",
            "-c",
            "TestMain.hpp"
        ],

By:

        "command": "c++ -c TestMain.hpp",

You don't have the error anymore?

[LKlemens]

Works like a charm

        "arguments": [
            "c++",
            "-c",
            "TestMain.hpp"
        ],

Error appearing with this:

"command": "c++ -c TestMain.hpp",

What version of Clang do you use?

[LKlemens]

clang version 5.0.1 ERR with rtags: rc -J . LIBCLANG TOOLING ERROR: json-compilation-database: Expected array.

Output with clang-check clang-check TestMain.cpp -p . Skipping /home/user/test/TestMain.cpp. Compile command not found.

I don't think Clang is the issue, I also use Clang 5.0.1, clang-tidy uses the Clang parsing facilities, and the compilation database is read without issues using command:

/tmp/testdir$ clang-tidy --version

    }
]

Wow, I've created json file with bear, and modified it with compdb again and it starts work :P Sorry for bothering you, next time I will be more careful and double check before create issue.
