Minimalist Logger based on slog with Otel for GoogleCloud

sog stands for Structured Otel GoogleCloud, inspired by clog. Special thanks to nownabe.

Key Features

When the log level is set to error, a stack trace will be displayed.


	The display of stack traces can be easily controlled at initialization. For example, you can configure it to hide stack traces locally, while enabling them on Google Cloud.

You can add additional information from the context (ctx) to labels.


	Insert code that corresponds to the following type during initialization `type LabelFieldInjector func(ctx context.Context) (key, value string, found bool)`

You can initialize slog with a one-liner at server startup, allowing you to use its default slog methods throughout your application

slog.SetDefault(slog.New(soglog.NewCloudLoggingHandler("your-project-id", &soglog.Options{IsStackTraced: true, LabelFieldInjector: yourLabelFieldInjector})

Note

soglog is strictly designed within the functionalities of the slog to support cloud logging. Therefore, soglog supports only 4 log levels: Debug, Info, Warn, and Error.
