Functions

func AddEnableDisableFlags added in v1.0.0 

func AddEnableDisableFlags(flags *pflag.FlagSet, target *OptionalBoolean, name, subject string)

AddEnableDisableFlags is a convenience method to generate --enable-something and --disable-something flags with the correct settings.

*name* specifies the name of the flags (eg. '--enable-[name]') *subject* is used to create the usage description for the flags, in the form of 'Enable [subject]'.

func AddEnableOrDisableFlag added in v1.0.0 

func AddEnableOrDisableFlag(flags *pflag.FlagSet, target *OptionalBoolean, defaultValue bool, name, subject string)

AddEnableOrDisableFlag is a convenience method to generate --enable-something *or* --disable-something flag with the correct settings, to overrider the default value. eg. if default is true, flag --disable-something will be generated.

*name* specifies the name of the flag (eg. '--enable-[name]') *subject* is used to create the usage description for the flag, in the form of 'Enable [subject]'.

func AddToggleFlag added in v1.0.0 

func AddToggleFlag(flags *pflag.FlagSet, target *OptionalBoolean, name string, defaultValue bool, usage string)

AddToggleFlag is a convenience method to generate --toggle type of a flag with the correct settings and a default value.

type Config 

type Config struct {

	// TODO: remove this after refactored
	Service     internal.Wrapper
	GlobalFlags GlobalFlags
	// contains filtered or unexported fields
}

Config holds the configuration for running upctl

func New

ClientTimeout is a convenience method that returns the user specified client timeout

func (*Config) ConfigBindFlagSet 

func (s *Config) ConfigBindFlagSet(flags *pflag.FlagSet)

ConfigBindFlagSet sets the config flag set and binds them to the viper instance

func (*Config) CreateService 

func (s *Config) CreateService() (internal.AllServices, error)

CreateService creates a new service instance and puts in the conf struct

func (*Config) FlagByKey 

func (s *Config) FlagByKey(key string) *pflag.Flag

FlagByKey returns pflag.Flag associated with a key in config

func (*Config) Get 

func (s *Config) Get(key string) interface{}

Get return the value of the key in the current namespace

func (*Config) GetString 

func (s *Config) GetString(key string) string

GetString is a convenience method of getting a configuration value in the current namespace as a string

func (*Config) IsSet 

func (s *Config) IsSet(key string) bool

IsSet return true if the key is set in the current namespace

func (*Config) Load 

func (s *Config) Load() error

Load loads config and sets up service

func (*Config) Output 

func (s *Config) Output() string

Output is a convenience method for getting the user specified output

func (*Config) OutputHuman 

func (s *Config) OutputHuman() bool

type GlobalFlags 

type GlobalFlags struct {
	ConfigFile    string        `valid:"-"`
	ClientTimeout time.Duration `valid:"-"`
	Debug         bool          `valid:"-"`
	OutputFormat  string        `valid:"in(human|json|yaml)"`
	NoColours     OptionalBoolean
	ForceColours  OptionalBoolean
}

GlobalFlags holds information on the flags shared among all commands

type OptionalBoolean added in v1.0.0 

type OptionalBoolean int

OptionalBoolean represents a boolean that can also be 'not set', eg. having three possible states. OptionalBoolean implements pflag.Value and flag.Value and as such, can be used with flag.Var() and friends. However, it does not allow to be set more than once, in order to support multiple flags touching the same boolean, eg. when the use case is --enable-something'/--disable-something 

const (
	// Unset is the OptionalBoolean value representing not set
	Unset OptionalBoolean = iota // 0
	// True is the OptionalBoolean value representing true
	True
	// False is the OptionalBoolean value representing false
	False

	// DefaultTrue is the OptionalBoolean value representing not set, but with a default value of true.
	// It returns false from IsSet, to allow for overriding the default (once)
	DefaultTrue
	// DefaultFalse is the OptionalBoolean value representing not set, but with a default value of false.
	// It returns false from IsSet, to allow for overriding the default (once)
	DefaultFalse
)

func (OptionalBoolean) AsUpcloudBoolean added in v1.0.0 

func (s OptionalBoolean) AsUpcloudBoolean() upcloud.Boolean

AsUpcloudBoolean return OptionalBoolean as upcloud.Boolean nb. DefaultTrue and DefaultEmpty return upcloud.Empty, as upcloud.Boolean has no concept of default values

func (OptionalBoolean) IsSet added in v1.0.0 

func (s OptionalBoolean) IsSet() bool

IsSet returns true if OptionalBoolean has been set

func (OptionalBoolean) OverrideNotSet added in v1.0.0 

func (s OptionalBoolean) OverrideNotSet(b bool) OptionalBoolean

OverrideNotSet returns a OptionalBoolean set to b if the original OptionalBoolean was not set

func (*OptionalBoolean) Set added in v1.0.0 

func (s *OptionalBoolean) Set(value string) error

Set implements flag.Value nb. OptionalBoolean will not allow itself to be set twice, if you want to have an underlying default value, use SetDefault()

func (*OptionalBoolean) SetDefault added in v1.0.0 

func (s *OptionalBoolean) SetDefault(b bool)

SetDefault sets the default value of OptionalBoolean to b Default value is returned from Value() if the OptionalBoolean has not been set

func (s OptionalBoolean) String() string

String implements flag.Value

func (OptionalBoolean) Type added in v1.0.0 

func (s OptionalBoolean) Type() string

Type implements pflag.Value

func (OptionalBoolean) Value added in v1.0.0
