Stapler Squad Logging System

This package implements a configurable logging system for Stapler Squad with the following features:

Key Features

  • Configurable Log Location: Logs are stored in ~/.stapler-squad/logs/ by default, but this can be changed in the config.
  • Global and Session-Specific Logs: Separate log files are created for each session.
  • Log Rotation: Logs are automatically rotated based on size and age.
  • Configuration Options: Several options can be configured in ~/.stapler-squad/config.json

Configuration

The following logging options can be configured in config.json:

{
  "logs_enabled": true,
  "logs_dir": "",  // Empty for default location (~/.stapler-squad/logs/)
  "log_max_size": 10,  // Max log file size in MB before rotation
  "log_max_files": 5,  // Max number of rotated files to keep
  "log_max_age": 30,  // Max age in days for rotated files
  "log_compress": true,  // Whether to compress rotated files
  "use_session_logs": true  // Whether to create separate log files for each session
}

Usage

Global Logging

The global loggers (InfoLog, WarningLog, and ErrorLog) can be used directly:

log.InfoLog.Printf("This is an info message")
log.WarningLog.Printf("This is a warning message")
log.ErrorLog.Printf("This is an error message")
Session-Specific Logging

For session-specific logging, use the LogForSession function:

// Log to session-specific file and global log
log.LogForSession("session-id", "info", "This is an info message for session %s", "session-id")
log.LogForSession("session-id", "warning", "This is a warning message for session %s", "session-id")
log.LogForSession("session-id", "error", "This is an error message for session %s", "session-id")

Implementation Details

  • Log files are stored in ~/.stapler-squad/logs/ by default
  • Global log file is named claudesquad.log
  • Session log files are named session_<session-id>.log
  • Log rotation is implemented using the lumberjack package
  • Logs are rotated when they reach the configured size
  • Old log files are compressed if the log_compress option is enabled

Functions

func Close 

func Close()

func DebugS 

func DebugS(message string, fields ...map[string]interface{})

DebugS logs a structured debug message

func ErrorS 

func ErrorS(message string, fields ...map[string]interface{})

ErrorS logs a structured error message

func FatalS 

func FatalS(message string, fields ...map[string]interface{})

FatalS logs a structured fatal message

func GetActiveSessionLogPaths 

func GetActiveSessionLogPaths() map[string]string

GetActiveSessionLogPaths returns the paths to all active session log files

func GetConfigDir 

func GetConfigDir() (string, error)

GetConfigDir returns the path to the application's configuration directory

func GetGlobalLogPath 

func GetGlobalLogPath() string

GetGlobalLogPath returns the path to the global log file

func GetLogDir 

func GetLogDir(cfg *LogConfig) (string, error)

GetLogDir returns the directory where logs should be stored

func GetLogFilePath 

func GetLogFilePath(cfg *LogConfig) (string, error)

GetLogFilePath returns the full path to the log file

func GetSessionLogFilePath 

func GetSessionLogFilePath(cfg *LogConfig, sessionID string) (string, error)

GetSessionLogFilePath returns the full path to a session-specific log file

func GetTestLogDir 

func GetTestLogDir() (string, error)

GetTestLogDir returns the directory where test logs should be stored Test logs are isolated in a dedicated subdirectory for easy cleanup

func InfoS 

func InfoS(message string, fields ...map[string]interface{})

func Initialize 

func Initialize(daemon bool)

func InitializeForTests 

func InitializeForTests(fileLevel LogLevel, consoleLevel LogLevel)

InitializeForTests sets up logging specifically for test environments with dual-stream configuration. This allows DEBUG logs to go to file while ERROR logs appear in console for immediate visibility.

Parameters:

  • fileLevel: Minimum level for file logging (typically DEBUG to capture everything)
  • consoleLevel: Minimum level for console logging (typically ERROR to avoid noise)

Example: 

log.InitializeForTests(log.DEBUG, log.ERROR)  // DEBUG→file, ERROR→console

func InitializeWithConfig 

func InitializeWithConfig(daemon bool, externalConfig interface{})

InitializeWithConfig sets up logging with the provided configuration.

func LogForSession 

func LogForSession(sessionID, level, format string, v ...interface{})

LogForSession logs a message to the session-specific log file

func LogSessionPathsToStderr 

func LogSessionPathsToStderr()

LogSessionPathsToStderr outputs session log file paths to stderr on exit

func WarningS 

func WarningS(message string, fields ...map[string]interface{})

WarningS logs a structured warning message

Types

type Every 

type Every struct {
	// contains filtered or unexported fields
}

Every is used to log at most once every timeout duration.

func NewEvery 

func NewEvery(timeout time.Duration) *Every

func (*Every) ShouldLog 

func (e *Every) ShouldLog() bool

ShouldLog returns true if the timeout has passed since the last log.
