Overview ¶

Package log prints install progress, preserving the "[step]: name" output the shell scripts produced so existing CI log scrapers keep working.

Functions ¶

func Elapsed ¶ added in v0.2.0

func Elapsed(start time.Time, label string)

Elapsed prints how long an operation took, as "(label took 1.234s)", so a slow install can be attributed to a step from its log alone. Use it as `defer log.Elapsed(time.Now(), "ko resolve")`: the start time is captured when the defer statement runs.

func Infof ¶

func Infof(format string, args ...any)

Infof prints an unadorned progress line.

func SetOutput ¶

func SetOutput(w io.Writer)

SetOutput redirects progress output, for tests.

func Step ¶

func Step(msg string)

Step announces a named install step. It takes a plain string rather than a format because most step names are computed (a demo name plus a suffix, a namespace/name pair), and a stray % in one of those should not be read as a verb.

func Stepf ¶

func Stepf(format string, args ...any)

Stepf announces a formatted install step.

func Warnf ¶

func Warnf(format string, args ...any)

Warnf prints a warning to stderr.

func Writer ¶ added in v0.4.0

func Writer() io.Writer

Writer is the destination progress output goes to, for callers that render several lines themselves rather than one step at a time.
