Constants ¶
This section is empty.
Variables ¶
var ( Timeout = 3 * time.Second ErrTimeout = errors.New("command timed out") )
var BigEndian bigEndian
BigEndian is the big-endian implementation of ByteOrder.
var ErrNotImplementedError = errors.New("not implemented yet")
var LittleEndian littleEndian
LittleEndian is the little-endian implementation of ByteOrder.
Functions ¶
func BootTimeWithContext ¶
func ByteToString ¶
func CallLsofWithContext ¶
func GetEnv ¶
GetEnv retrieves the environment variable key. If it does not exist it returns the default.
func GetEnvWithContext ¶
func GetEnvWithContext(ctx context.Context, key string, dfault string, combineWith ...string) string
GetEnvWithContext retrieves the environment variable key. If it does not exist it returns the default. The context may optionally contain a map superseding os.EnvKey.
func GetOSRelease ¶
func GetOSReleaseWithContext ¶
func HostDevWithContext ¶
func HostEtcWithContext ¶
func HostProcWithContext ¶
func HostRootWithContext ¶
func HostRunWithContext ¶
func HostSysWithContext ¶
func HostVarWithContext ¶
func IntContains ¶
IntContains checks the src in any int of the target int slice.
func IntToString ¶
func IsLittleEndian ¶
func IsLittleEndian() bool
IsLittleEndian checks if the current platform uses little-endian. copied from https://github.com/ntrrg/ntgo/blob/v0.8.0/runtime/infrastructure.go#L16 (MIT License)
func PathExists ¶
func PathExistsWithContents ¶
PathExistsWithContents returns the filename exists and it is not empty
func Read ¶
Read reads structured binary data from r into data. Data must be a pointer to a fixed-size value or a slice of fixed-size values. Bytes read from r are decoded using the specified byte order and written to successive fields of the data. When reading into structs, the field data for fields with blank (_) field names is skipped; i.e., blank field names may be used for padding. When reading into a struct, all non-blank fields must be exported.
func ReadLine ¶
ReadLine reads a file and returns the first occurrence of a line that is prefixed with prefix.
func ReadLines ¶
ReadLines reads contents from a file and splits them by new lines. A convenience wrapper to ReadLinesOffsetN(filename, 0, -1).
func ReadLinesOffsetN ¶
ReadLinesOffsetN reads contents from file and splits them by new line. The offset tells at which line number to start. The count determines the number of lines to read (starting from offset): n >= 0: at most n lines n < 0: whole file
func Size ¶
func Size(v interface{}) int
Size returns how many bytes Write would generate to encode the value v, which must be a fixed-size value or a slice of fixed-size values, or a pointer to such data. If v is neither of these, Size returns -1.
func StringsContains ¶
StringsContains checks the src in any string of the target string slice
func StringsHas ¶
StringsHas checks the target string slice contains src or not
func UintToString ¶
func Virtualization ¶
func Write ¶
Write writes the binary representation of data into w. Data must be a fixed-size value or a slice of fixed-size values, or a pointer to such data. Bytes written to w are encoded using the specified byte order and read from successive fields of the data. When writing structs, zero values are written for fields with blank (_) field names.
Types ¶
type ByteOrder ¶
type ByteOrder interface {
Uint16([]byte) uint16
Uint32([]byte) uint32
Uint64([]byte) uint64
PutUint16([]byte, uint16)
PutUint32([]byte, uint32)
PutUint64([]byte, uint64)
String() string
}
A ByteOrder specifies how to convert byte sequences into 16-, 32-, or 64-bit unsigned integers.
type FakeInvoke ¶
type FakeInvoke struct {
Suffix string // Suffix species expected file name suffix such as "fail"
Error error // If Error specified, return the error.
}
func (FakeInvoke) Command ¶
func (i FakeInvoke) Command(name string, arg ...string) ([]byte, error)
Command in FakeInvoke returns from expected file if exists.
