it seems it would be good idea to refactor

if (global.params.v.messageStyle == MessageStyle.lsp)
            {
                printLSPDiagnostic(format, ap, info);
                return;
            }
            if (global.params.v.messageStyle == MessageStyle.sarif)
            {
                addSarifDiagnostic(loc, format, ap, kind);
                return;
            }
            printDiagnostic(format, ap, info);

and make printDiagnostic take the message style as an argument

leave to newline at EOF in place

also you will probably have to update frontend.h with this change, see the CircleCI failure

[Iskaban10]

Like this in frontend.h?

enum class MessageStyle : uint8_t
{
    digitalmars = 0u,
    gnu = 1u,
    sarif = 2u,
    lsp = 3u,
};

[thewilsonator]

yes
