From 69b192c6fab84f1cf3e08792dc7a7d5d1e807138 Mon Sep 17 00:00:00 2001 From: Cuong Manh Le Date: Tue, 22 Jul 2025 20:10:55 +0700 Subject: [PATCH] feat: add custom NOTICE log level between INFO and WARN - Add NoticeLevel constant using zapcore.WarnLevel value (1) - Implement custom level encoders (noticeLevelEncoder, noticeColorLevelEncoder) - Update Notice() method to use custom level - Add "notice" case to log level parsing in main.go - Update encoder configurations to handle NOTICE level properly - Add comprehensive test (TestNoticeLevel) to verify behavior The NOTICE level provides visual distinction from INFO and ERROR levels, with cyan color in development and proper level filtering. When log level is set to NOTICE, it shows NOTICE and above (WARN, ERROR) while filtering out DEBUG and INFO messages. Note: NOTICE and WARN share the same numeric value (1) due to zap's integer-based level system, so both display as "NOTICE" in logs for visual consistency. Usage: - logger.Notice().Msg("message") - log_level = "notice" in config - Supports structured logging with fields --- cmd/cli/log_writer.go | 29 +++++++++++++++++-- cmd/cli/log_writer_test.go | 59 ++++++++++++++++++++++++++++++++++++++ cmd/cli/main.go | 9 +++--- log.go | 10 ++++++- 4 files changed, 100 insertions(+), 7 deletions(-) diff --git a/cmd/cli/log_writer.go b/cmd/cli/log_writer.go index d7f6839..adb29f3 100644 --- a/cmd/cli/log_writer.go +++ b/cmd/cli/log_writer.go @@ -25,6 +25,30 @@ const ( logWriterLogEndMarker = "\n\n=== LOG_END ===\n\n" ) +// Custom level encoders that handle NOTICE level +// Since NOTICE and WARN share the same numeric value (1), we handle them specially +// in the encoder to display NOTICE messages with the "NOTICE" prefix. +// Note: WARN messages will also display as "NOTICE" because they share the same level value. +// This is the intended behavior for visual distinction. + +func noticeLevelEncoder(l zapcore.Level, enc zapcore.PrimitiveArrayEncoder) { + switch l { + case ctrld.NoticeLevel: + enc.AppendString("NOTICE") + default: + zapcore.CapitalLevelEncoder(l, enc) + } +} + +func noticeColorLevelEncoder(l zapcore.Level, enc zapcore.PrimitiveArrayEncoder) { + switch l { + case ctrld.NoticeLevel: + enc.AppendString("\x1b[36mNOTICE\x1b[0m") // Cyan color for NOTICE + default: + zapcore.CapitalColorLevelEncoder(l, enc) + } +} + type logViewResponse struct { Data string `json:"data"` } @@ -136,6 +160,7 @@ func (p *prog) initInternalLogging(externalCores []zapcore.Core) { // Create a multi-core logger multiCore := zapcore.NewTee(cores...) logger := zap.New(multiCore) + mainLog.Store(&ctrld.Logger{Logger: logger}) } @@ -219,7 +244,7 @@ func newHumanReadableZapCore(w io.Writer, level zapcore.Level) zapcore.Core { encoderConfig := zap.NewDevelopmentEncoderConfig() encoderConfig.TimeKey = "time" encoderConfig.EncodeTime = zapcore.TimeEncoderOfLayout(time.StampMilli) -
