Great! First, read this page (including the small print at the end). ### Before you contribute Before we can use your code, you must sign the [Google Individual Contributor License Agreement] (https://cla.developers.google.com/about/google-individual) (CLA), which you can do online. The CLA is necessary mainly because you own the copyright to your changes, even after your contribution becomes part of our codebase, so we need your permission to use and distribute your code. We also need to be sure of various other things—for instance that you'll tell us if you know that your code infringes on other people's patents. You don't have to sign the CLA until after you've submitted your code for review and a member has approved it, but you must do it before we can put your code into our codebase. Before you start working on a larger contribution, you should get in touch with us first through the issue tracker with your idea so that we can help out and possibly guide you. Coordinating up front makes it much easier to avoid frustration later on. ### Code reviews All submissions, including submissions by project members, require review. We use Github pull requests for this purpose. ### The small print Contributions made by corporations are covered by a different agreement than the one above, the [Software Grant and Corporate Contributor License Agreement] (https://cla.developers.google.com/about/google-corporate). logger-1.1.1/LICENSE000066400000000000000000000261361404427702100140070ustar00rootroot00000000000000 Apache License Version 2.0, January 2004 http://www.apache.org/licenses/ TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 1.

This is not an official Google product. ## Usage ## Set up the default logger to log the system log (event log or syslog) and a file, include a flag to turn up verbosity: ```go import ( "flag" "os" "github.com/google/logger" ) const logPath = "/some/location/example.log" var verbose = flag.Bool("verbose", false, "print info level logs to stdout") func main() { flag.Parse() lf, err := os.OpenFile(logPath, os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0660) if err != nil { logger.Fatalf("Failed to open log file: %v", err) } defer lf.Close() defer logger.Init("LoggerExample", *verbose, true, lf).Close() logger.Info("I'm about to do something!") if err := doSomething(); err != nil { logger.Errorf("Error running doSomething: %v", err) } } ``` The Init function returns a logger so you can setup multiple instances if you wish, only the first call to Init will set the default logger: ```go lf, err := os.OpenFile(logPath, os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0660) if err != nil { logger.Fatalf("Failed to open log file: %v", err) } defer lf.Close() // Log to system log and a log file, Info logs don't write to stdout. loggerOne := logger.Init("LoggerExample", false, true, lf) defer loggerOne.Close() // Don't to system log or a log file, Info logs write to stdout.. loggerTwo := logger.Init("LoggerExample", true, false, ioutil.Discard) defer loggerTwo.Close() loggerOne.Info("This will log to the log file and the system log") loggerTwo.Info("This will only log to stdout") logger.Info("This is the same as using loggerOne") ``` ## Custom Format ## | Code | Example | |--------------------------------------|----------------------------------------------------------| | `logger.SetFlags(log.Ldate)` | ERROR: 2018/11/11 Error running Foobar: message | | `logger.SetFlags(log.Ltime)` | ERROR: 09:42:45 Error running Foobar: message | | `logger.SetFlags(log.Lmicroseconds)` | ERROR: 09:42:50.776015 Error running Foobar: message | | `logger.SetFlags(log.Llongfile)` | ERROR: /src/main.go:31: Error running Foobar: message | | `logger.SetFlags(log.Lshortfile)` | ERROR: main.go:31: Error running Foobar: message | | `logger.SetFlags(log.LUTC)` | ERROR: Error running Foobar: message | | `logger.SetFlags(log.LstdFlags)` | ERROR: 2018/11/11 09:43:12 Error running Foobar: message | ```go func main() { lf, err := os.OpenFile(logPath, …, 0660) defer logger.Init("foo", *verbose, true, lf).Close() logger.SetFlags(log.LstdFlags) } ``` More info: https://golang.org/pkg/log/#pkg-constants logger-1.1.1/go.mod000066400000000000000000000001461404427702100141010ustar00rootroot00000000000000module github.com/google/logger go 1.12 require golang.org/x/sys v0.0.0-20210426230700-d19ff857e887 logger-1.1.1/go.sum000066400000000000000000000003171404427702100141260ustar00rootroot00000000000000golang.org/x/sys v0.0.0-20210426230700-d19ff857e887 h1:dXfMednGJh/SUUFjTLsWJz3P+TQt9qnR11GgeI3vWKs= golang.org/x/sys v0.0.0-20210426230700-d19ff857e887/go.mod h1:h1NjWce9XRLGQEsW7wpKNCjG9DtNlClVuFLEZdDNbEs= logger-1.1.1/logger.go000066400000000000000000000326241404427702100146070ustar00rootroot00000000000000/* Copyright 2016 Google Inc.
