Functions ¶

func CloseDB ¶

func CloseDB(db *sql.DB, dbPath string)

CloseDB closes the database and removes the temp file without writing output.

func OpenDB ¶

func OpenDB() (*sql.DB, string, error)

OpenDB reads a serialized sqlite database from stdin (if piped) or creates a fresh one, ensures the standard schema exists, and returns an open *sql.DB along with the temp file path. The caller must call OutputDB or CloseDB when done.

func OutputDB ¶

func OutputDB(db *sql.DB, dbPath string) error

OutputDB writes the database to stdout if piped, or prints a message to stderr if stdout is a terminal. It closes the database and removes the temp file in all cases.

func ZeroFill ¶

func ZeroFill(a string, size int) string

ZeroFill left-pads a string with zeros to the given size.

Types ¶

type Logger ¶

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

Logger writes log entries to both a database table and stderr. INFO and WARN go to the database only. ERROR goes to both.

func NewLogger ¶

func NewLogger(db *sql.DB, component string) *Logger

NewLogger creates a logger that tags entries with the given component name.

func (*Logger) Error ¶
