Log Format

Backend format

See spdlog wiki : Custom formatting

The default pattern is : [%D %T] [%=10n] %^[pid : %P] [tid : %t] [%L] %v%$

Frontend format

All the frontend message will be the %v value to backend.

The default MessageConvert is below:

public typealias MessageConvert = (_ message: CustomStringConvertible?, _ filename: String, _ function: String, _ line: Int) -> String

public func register(messageConvert: @escaping MessageConvert) {
    __messageConvert = messageConvert
}

var __messageConvert: MessageConvert = { message, filename, function, line in
    let fileName = filename.components(separatedBy: "/").last ?? ""
    let allMessage = "[\(fileName):\(line)] \(function) - \(message?.description ?? "")"
    return allMessage
}

You can call

Senna.register(messageConvert: your_custom_message_convert)

to disable filename,function,line or whatever you want.
