Clay Logging Section
This package provides a Glazed field section for configuring logging in Clay applications.
Documentation
📖 For API reference and detailed usage, see: Logging Section API Reference
🎓 To learn how to create custom sections, see: Custom Section Tutorial
Quick Overview
The logging section provides:
- Log Level: Control verbosity (
debug,info,warn,error,fatal) - Log Format: Choose between text and JSON formats
- Log File: Specify output file (defaults to stderr)
- Caller Info: Include caller information in logs
Quick Usage
import "github.com/go-go-golems/glazed/pkg/cmds/logging"
// In your command's Run method:
if err := logging.SetupLoggingFromValues(parsedSections); err != nil {
return err
}
log.Info().Msg("Logging is now configured!")

Functions ¶
func AddLoggingSectionToCommand ¶ added in v1.0.0
AddLoggingSectionToCommand adds the logging section to a Glazed command
func AddLoggingSectionToRootCommand ¶ added in v1.0.0
func InitEarlyLoggingFromArgs ¶ added in v0.7.5
InitEarlyLoggingFromArgs initializes logging from command-line arguments before cobra commands are registered. This allows logging configuration (like --log-level) to be respected during command discovery/loading.
This function: - Filters args to only logging flags (ignores unknown flags) - Parses flags using a standalone pflag.FlagSet - Initializes the global logger with parsed settings
Defaults match AddLoggingSectionToRootCommand in section.go.
func InitLoggerFromCobra ¶ added in v0.7.0
InitLoggerFromCobra initializes the logger using flags parsed by Cobra on the given command. Call this in PersistentPreRun(E) to initialize logging after Cobra parsed flags but before command execution. Flags are added by AddLoggingSectionToRootCommand.
func InitLoggerFromSettings ¶
func InitLoggerFromSettings(settings *LoggingSettings) error
InitLoggerFromSettings initializes the logger based on the provided settings
func InitLoggerWithConfig ¶
func NewLoggingSection ¶ added in v1.0.0
NewLoggingSection creates a new section for logging configuration
func SetupLoggingFromValues ¶ added in v1.0.0
SetupLoggingFromValues configures global logger from command-line fields
Types ¶
type LoggingSettings ¶
type LoggingSettings struct {
WithCaller bool `glazed:"with-caller"`
LogLevel string `glazed:"log-level"`
LogFormat string `glazed:"log-format"`
LogFile string `glazed:"log-file"`
LogToStdout bool `glazed:"log-to-stdout"`
}
LoggingSettings holds the logging configuration fields
func GetLoggingSettings ¶ added in v0.6.2
func GetLoggingSettings(parsedValues *values.Values) (*LoggingSettings, error)
GetLoggingSettings extracts logging configuration for custom validation or setup
