Functions ¶

func Fail ¶

func Fail(err error)

func Failf ¶

func Failf(msg string, args ...interface{})

func FuzzParseFlags ¶

func FuzzParseFlags(data []byte) int

func Init ¶

func Init() func()

Init handles common tasks for command line tools:

invokes flag.Parse
adds support for optional flags (see OptionalFlags)
adds support for cpu/mem profiling (-cpuprofile/memprofile flags)

Use as defer tool.Init()().

func OptionalFlags ¶

func OptionalFlags(flags []Flag) string

OptionalFlags produces command line flag value that encapsulates the given flags as optional. This is intended for programmatic use only when we invoke older versions of binaries with new unsupported flags. Use tool.Init to support optional flags in the binary. The format keeps flags reasonably readable ("-optional=foo=bar:baz=123"), not subject to accidental splitting into multiple arguments due to spaces and supports bool/non-bool flags.

func ParseFlags ¶

func ParseFlags(set *flag.FlagSet, args []string) error

Types ¶

type CfgsFlag ¶

type CfgsFlag []string

CfgsFlag allows passing a list of configuration files to the same flag and provides parsing utilities.

func (*CfgsFlag) Set ¶

func (cfgs *CfgsFlag) Set(value string) error

Set is used by flag.Parse to correctly parse the command line arguments.

func (*CfgsFlag) String ¶

func (cfgs *CfgsFlag) String() string

String correctly converts the flag values into a string which is required to parse them afterwards.

type Flag ¶

type Flag struct {
	Name  string
	Value string
}
