Leveled execution logs for Go.

This is an efficient pure Go implementation of leveled logs in themanner of the open source C++ packageglog.

By binding methods to booleans it is possible to use the log package without paying the expense of evaluating the arguments to the log. Through the-vmodule flag, the package also provides fine-grainedcontrol over logging at the file level.

The comment fromglog.go introduces the ideas:

Packageglog implements logging analogous to the Google-internal C++ INFO/ERROR/V setup. It provides the functions Info, Warning, Error, Fatal, plus formatting variants such as Infof. It also provides V-style loggingcontrolled by the-v and-vmodule=file=2 flags.

Basic examples:

glog.Info("Prepare to repel boarders")glog.Fatalf("Initialization failed: %s",err)

See the documentation for the V function for an explanation of these examples:

ifglog.V(2) {glog.Info("Starting transaction...")}glog.V(2).Infoln("Processed",nItems,"elements")

The repository contains an open source version of the log package used inside Google. The master copy of the source lives inside Google, not here. The code in this repo is for export only and is not itself under development. Feature requests will be ignored.
