From 8c49f9305be23f0abe90fb540185b8fc8d41ff1e Mon Sep 17 00:00:00 2001 From: ArditZubaku Date: Tue, 2 Sep 2025 11:45:44 +0200 Subject: [PATCH] feat: replace go-logging with logrus and expose native logger - Replace github.com/op/go-logging with github.com/sirupsen/logrus - Expose goesl.Logger directly for full logrus functionality access - Maintain backward compatibility with existing logging functions - Add support for structured logging with fields and context - Preserve environment variable configuration (GOESL_LOG_LEVEL, GOESL_LOG_FORMAT) - Use logrus native ParseLevel() for better error handling - Enable thread-safe logging operations with built-in atomics - Update documentation with advanced usage examples - Add Go module support (go.mod/go.sum) Breaking changes: None - all existing logging function calls remain compatible New features: Direct access to logrus logger for advanced logging capabilities --- .travis.yml | 4 +-- README.md | 95 +++++++++++++++++++++++++++++++++++++++++++++++++++-- logger.go | 72 ++++++++++++++++++++++++++++++---------- 3 files changed, 150 insertions(+), 21 deletions(-) diff --git a/.travis.yml b/.travis.yml index 1f333fc..ec86094 100644 --- a/.travis.yml +++ b/.travis.yml @@ -5,10 +5,10 @@ go: - 1.4 - 1.5 - tip - + install: - go get -v "github.com/smartystreets/goconvey" - - go get -v "github.com/op/go-logging" + - go get -v "github.com/sirupsen/logrus" script: - go test -run="TestJustToTest" diff --git a/README.md b/README.md index 3e290bb..8f39c65 100644 --- a/README.md +++ b/README.md @@ -14,7 +14,7 @@ Point of this library is to fully implement FreeSWITCH ESL and bring outbound se Before using this code, please read following discussion: https://github.com/0x19/goesl/discussions/35 -In short, I don't have time right now contributing to this project. +In short, I don't have time right now contributing to this project. ### TODO? @@ -28,8 +28,99 @@ There are few different types of examples that can be found at [GoESL Examples]( Feel free to suggest more examples :) +### Logging -### Contributions / Issues? +GoESL now uses [logrus](https://github.com/sirupsen/logrus) for structured logging. The underlying logrus logger is exposed directly as `goesl.Logger`, giving you full access to all logrus functionality including atomic operations, structured logging with fields, hooks, and advanced configuration. + +#### Direct Logger Access + +The most powerful way to configure logging is to use the exposed logger directly: + +```go +import ( + "github.com/0x19/goesl" + "github.com/sirupsen/logrus" +) + +// Set log level using logrus types (thread-safe with built-in atomics) +goesl.Logger.SetLevel(logrus.DebugLevel) + +// Use any logrus formatter +goesl.Logger.SetFormatter(&logrus.JSONFormatter{}) + +// Add structured logging with fields +goesl.Logger.WithFields(logrus.Fields{ + "user_id": 123, + "action": "login", +}).Info("User logged in") + +// Use context-aware logging +goesl.Logger.WithField("component", "auth").Warn("Authentication failed") +``` + +#### Convenience Functions (Backward Compatibility) + +For backward compatibility, the original logging functions are still available: + +```go +goesl.Debug("Debug message") +goesl.Info("Info message") +goesl.Warning("Warning message") +goesl.Error("Error message") +goesl.Fatal("Fatal message") +goesl.Panic("Panic message") +goesl.Trace("Trace message") +``` + +#### Environment Variables + +You can also configure logging via environment variables: + +```bash +# Set log level (panic, fatal, error, warn, info, debug, trace) +export GOESL_LOG_LEVEL=debug + +# Set log format (text or json) +export GOESL_LOG_FORMAT=json +``` + +#### Advanced Usage Examples + +```go +package main + +import ( + "github.com/0x19/goesl" + "github.com/sirupsen/logrus" +) + +func main() { + // Configure logger directly with full logrus power + goesl.Logger.SetLevel(logrus.TraceLevel) + goesl.Logger.SetFormatter(&logrus.JSONFormatter{ + PrettyPrint: true, + }) + + // Structured logging + logger := goesl.Logger.WithFields(logrus.Fields{ + "service": "freeswitch-client", + "version": "1.0.0", + }) + + logger.Info("Service starting") + + // Context-aware logging + goesl.Logger.WithField("call_id", "123").Debug("Processing call") + + // Use all logrus features: hooks, custom formatters, etc. + // Check current level + if goesl.Logger.IsLevelEnabled(logrus.DebugLevel) { + goesl.Logger.Debug("Debug logging is enabled") + } +} +``` + +This approach gives you the full power of logrus while maintaining backward compatibility with the original GoESL logging functions.### Contributions / Issues?
