Types

type Shutdown

type Shutdown func()

Shutdown is a function that needs to be called to perform the final cleanup.

func Init

func Init() Shutdown

Init should be called once at the beginning at each executable that doesn't use the github.com/grailbio/base/cmdutil. The Shutdown function should be called to perform the final cleanup (closing logs for example).

Init also applies a default configuration profile (see package github.com/grailbio/base/config), and adds profile flags to the default flag set. The default profile path used is $HOME/grail/profile.

Note that this function will call flag.Parse().

Suggested use:

shutdown := grail.Init()
defer shutdown()

type VlogOutputter struct{}

VlogOutputter implements base/log.Outputter backed by vlog.

func (VlogOutputter) Level
