log
An O(1) constant time logging system that allows you to connect one log to multiple writers (e.g. stdout, a file and a TCP connection).
Installation
go get -u github.com/aerogo/log/...
Example
hello := log.New() // Create a new log
hello.AddWriter(log.File("hello.log")) // Add a writer
hello.Info("Hello World %d %d %d", 1, 2, 3) // Write non-critical data (buffered)
hello.Error("Something went wrong") // Force an immediate I/O flush for error messages
Under the hood
All Write calls are queued into a channel that is read in a separate goroutine. Once the channel receives new data it writes the data to all registered outputs.

type Log ¶
type Log struct {
// contains filtered or unexported fields
}
Log is a log data source used for a specific part of your application, e.g. "web", "database", "api" or other categories. It can be connected to multiple writers.
func (*Log) Error ¶
Error writes critical information to the log. It will instantly flush the I/O buffers and guarantees that the message will have been written persistenly to disk at the time this function returns.
