Custom Labels

Override the default level labels with SetLevelLabels:

clog.SetLevelLabels(clog.LevelMap{
  clog.InfoLevel:  "INFO",
  clog.WarnLevel:  "WARNING",
  clog.ErrorLevel: "ERROR",
})

Missing levels fall back to the defaults. Use DefaultLabels() to get a copy of the default label map.

Level Alignment

When custom labels have different widths, control alignment with SetLevelAlign:

clog.SetLevelAlign(clog.AlignRight)   // default: "   INFO", "WARNING", "  ERROR"
clog.SetLevelAlign(clog.AlignLeft)    //          "INFO   ", "WARNING", "ERROR  "
clog.SetLevelAlign(clog.AlignCenter)  //          " INFO  ", "WARNING", " ERROR "
clog.SetLevelAlign(clog.AlignNone)    //          "INFO",    "WARNING", "ERROR"
