Overview

Package log centralizes slog setup. The root cobra command installs the process-wide default logger in its PersistentPreRunE (internal/cli/root.go), which is what makes a slog.Warn from internal/render or internal/marketplace render as an agentsync diagnostic instead of a timestamped stdlib log line.

That wiring IS this package. Without it, library-side slog falls through to slog's default handler — the shape #211 was reported against.

Functions

func Detach added in v0.13.0

func Detach()

Detach points the process default at a discarding handler.

For TEST BINARIES. A real process installs once and exits, so the handler's writer outlives it. A test binary runs many Execute() cycles, each leaving slog.Default() bound to that invocation's stderr — usually a *bytes.Buffer owned by a test that has already finished. A later library slog.Warn then writes into a dead buffer: silent today, a data race under t.Parallel.

Discarding, not restoring the original: the original is the stdlib handler, whose timestamped stderr lines are the shape this package replaces. A test that wants to observe records installs its own handler.

func Install added in v0.13.0

func Install(w io.Writer, p *ui.Printer, verbose bool)

Install makes New's logger the process-wide slog default. Detach is the undo.

func New

func New(w io.Writer, p *ui.Printer, verbose bool) *slog.Logger

New returns a slog.Logger that renders through p's diagnostic vocabulary, writing to w. Debug level when verbose, otherwise Info.

This level gates only slog-sourced diagnostics. It is not a global quiet switch: a command's own output and its direct p.Warnf calls are not slog records and are unaffected.
