# slog
Simple logger for Go with no dependencies
A simple logger for Go with no dependencies
I know there are many go loggers out there that offer various logging features such as file rotation, granular verbosity settings, colored and JSON output, etc.
_Slog is not one of them._
Slog lets you hide or show debug logs as well as provides a simpler way to log messages with Warning and Error prefixes for consistency.
Also provided are a few simple methods for handling returned `error` variables, logging them out and optionally panicing or fatally exiting.
## Documentation
package slog // import "git.iamthefij.com/iamthefij/slog"
Package slog is a super simple logger that allows a few convenience methods
for handling debug vs warning/error logs. It also adds a few conveniences
for handling errors.
VARIABLES
var (
// DebugLevel indicates if we should log at the debug level
DebugLevel = true
)
FUNCTIONS
func Debug(format string, v ...interface{})
Debug will log with a DEBUG prefix if DebugLevel is se
func Error(format string, v ...interface{})
Error will log with a ERROR prefix
func FatalOnErr(err error, format string, v ...interface{})
FatalOnErr if error provided, will log out details of an error and exi
func Info(format string, v ...interface{})
Info formats logs with an INFO prefix
func Log(format string, v ...interface{})
Log formats logs directly to the main logger
func PanicOnErr(err error, format string, v ...interface{})
PanicOnErr if error provided, will log out details of an error and exi
func SetFlags(flag int)
SetFlags allows changing the logger flags using flags found in `log`
func WarnOnErr(err error, format string, v ...interface{})
WarnOnErr if error provided, will provide a warning if an error is provided
func Warning(format string, v ...interface{})
Warning will log with a WARNING prefix
