How do i get the variable names directly from the diagnostic engine output?

[trile127]

I would like to get the arguments from the following error diagnostic message: "data_to_send" and "data_to_send_buff"

How would i do so?

for (auto &diag : diags) {
diagEngine.issue(diag);
SPDLOG_INFO("Diag: Code {}", slang::toString(diag.code));
std::string message = diagEngine.formatMessage(diag);
SPDLOG_INFO("Diag: message {}", message);
}

uart_tx_reg_change.v:124:13: error: use of undeclared identifier 'data_to_send'; did you mean 'data_to_send_buf'?
            data_to_send <= uart_tx_data;

The Diagnostic object has an args member containing all of the arguments, in order.

How would i print out the arg as a string? Its like this weird custom type

Because i. need to do something like this:

 // Dynamically build up the list of arguments to pass to the formatting routines.
    fmt::dynamic_format_arg_store<fmt::format_context> args;
    for (auto& arg : diag.args) {
        // Unwrap the argument type (stored as a variant).
        std::visit(
            [&](auto&& t) {
                // If the argument is a pointer, the fmtlib API needs it unwrapped into a reference.
                using T = std::decay_t<decltype(t)>;
                if constexpr (std::is_same_v<Diagnostic::CustomArgType, T>) {
                    if (auto it = formatters.find(t.first); it != formatters.end())
                        args.push_back(it->second->format(t.second));
                    else
                        SLANG_THROW(std::runtime_error("No diagnostic formatter for type"));
                }
                else if constexpr (std::is_same_v<ConstantValue, T>) {
                    if (t.isReal())
                        args.push_back(double(t.real()));
                    else if (t.isShortReal())
                        args.push_back(float(t.shortReal()));
                    else
                        args.push_back(t.toString());
                }
                else {
                    args.push_back(t);
                }
            },
            arg);
    }

But formatters is private

That method could be made public if it were helpful.
