Types ¶

type Profile ¶

type Profile struct {
	Name          string
	DataDir       string // Where to store config and cache
	ConfigPerm    os.FileMode
	SecurePerm    os.FileMode
	DirPerm       os.FileMode
	UseHardwareID bool   // Use device-specific encryption
	DeviceIDPath  string // Path to hardware identifier
}

Profile defines deployment-specific configuration

func Detect ¶

func Detect() *Profile

Detect identifies the deployment environment and returns the matching Profile. It is cheap (a few os.Stat calls + runtime.GOOS) — callers that need the profile repeatedly should cache the returned pointer locally instead of re-invoking.

func (*Profile) GetCachePath ¶

func (p *Profile) GetCachePath() (string, error)

GetCachePath returns the full cache file path.

func (*Profile) GetConfigPath ¶

func (p *Profile) GetConfigPath() (string, error)

GetConfigPath returns the full config file path.

func (*Profile) GetDataDir ¶

func (p *Profile) GetDataDir() (string, error)

GetDataDir returns the expanded data directory path. It fails loudly when $HOME/$APPDATA cannot be resolved — silently returning "/.dddns" would cause dddns to try to write under the filesystem root.

func (*Profile) GetSecurePath ¶

func (p *Profile) GetSecurePath() (string, error)

GetSecurePath returns the full secure config path.
