     4  Leveled execution logs for Go.
     5  
     6  This is an efficient pure Go implementation of leveled logs in the
     7  manner of the open source C++ package
     8  	https://github.com/google/glog
     9  
    10  By binding methods to booleans it is possible to use the log package
    11  without paying the expense of evaluating the arguments to the log.
    12  Through the -vmodule flag, the package also provides fine-grained
    13  control over logging at the file level.
    14  
    15  The comment from glog.go introduces the ideas:
    16  
    17  	Package glog implements logging analogous to the Google-internal
    18  	C++ INFO/ERROR/V setup.  It provides functions Info, Warning,
    19  	Error, Fatal, plus formatting variants such as Infof. It
    20  	also provides V-style logging controlled by the -v and
    21  	-vmodule=file=2 flags.
    22  	
    23  	Basic examples:
    24  	
    25  		glog.Info("Prepare to repel boarders")
    26  	
    27  		glog.Fatalf("Initialization failed: %s", err)
    28  	
    29  	See the documentation for the V function for an explanation
    30  	of these examples:
    31  	
    32  		if glog.V(2) {
    33  			glog.Info("Starting transaction...")
    34  		}
    35  	
    36  		glog.V(2).Infoln("Processed", nItems, "elements")
    37

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