func GetPluginName added in v0.17.0

func GetPluginName(plugin string) string

GetPluginName function is used to get the plugin name required while installing/updating/removing a plugin. External plugins require the repo names to be prefixed(eg: francois2metz/scalingo). Sample input 1: hub.steampipe.io/plugins/francois2metz/scalingo@latest Sample output 1: francois2metz/scalingo Sample input 2: hub.steampipe.io/plugins/turbot/aws@latest Sample output 2: aws

func IsContextCancelled

func IsContextCancelled(ctx context.Context) bool

func IsMacM1

func IsMacM1() (bool, error)

IsMacM1 returns whether the system is a Mac M1 machine

func IsPortBindable

func IsPortBindable(port int) error

func IsWSL

func IsWSL() bool

IsWSL detects whether app is running in WSL environment refer to: https://github.com/Microsoft/WSL/issues/423#issuecomment-679190758

func LocalAddresses

func LocalAddresses() ([]string, error)

func LogTime

func LogTime(operation string)

func Map

func Map[V any, M any](elements []V, mapper func(V) M) []M

Map returns a new slice where every value is mapped to a new value through the mapper

The mapper is invoked with each element

func MergeMaps added in v0.17.0

func MergeMaps[M ~map[K]V, K comparable, V any](old, new M) M

MergeMaps merges 'new' onto 'old'. Values existing in old already have precedence Any value existing in new but not old is added to old

func MoveFile

func MoveFile(source string, destination string) error

MoveFile moves a file from source to destiantion.

It first attempts the movement using OS primitives (os.Rename)
If os.Rename fails, it copies the file byte-by-byte to the destination and then removes the source

func PadRight added in v0.16.2

func PadRight(str string, length int, pad byte) string

PadRight returns a new string of a specified length in which the end of the current string is padded with spaces or with a specified Unicode character.

func ParseCertificateInLocation added in v0.17.0

func ParseCertificateInLocation(location string) (*x509.Certificate, error)

func Partition

func Partition[V any](elements []V, predicate func(V) bool) ([]V, []V)

Partition splits the array of elements into two groups: the left partition contains elements that the predicate returns `true` for. the right partition contains elements that the predicate returns `false` for.

The predicate is invoked with each element

func PidExists

func PidExists(targetPid int) (bool, error)

PidExists scans through the list of PIDs in the system and checks for the `targetPID`.

PidExists uses iteration, instead of signalling, since we have observed that signalling does not always work reliably when the destination of the signal is a child of the source of the signal - which may be the case then starting implicit services

func Pluralize

func Pluralize(base string, count int) string

Pluralize :: pluralizes a word (if applicable) based on provided count

func PrettifyJsonFromReader added in v0.17.0

func PrettifyJsonFromReader(dataToExport io.Reader) (io.Reader, error)

func RemoveDirectoryContents(removePath string) error

func Resize added in v0.16.2

func Resize(s string, length uint) string

Resize resizes the string with the given length. It ellipses with '…' when the string's length exceeds the desired length or pads spaces to the right of the string when length is smaller than desired

func SafeIntEqual

func SafeIntEqual(i1, i2 *int) bool

func SafeStringsEqual

func SafeStringsEqual(s1, s2 interface{}) bool

func SendRequest

func SendRequest(signature string, method string, sendRequestTo url.URL, payload *bytes.Buffer, timeout time.Duration) (*http.Response, error)

Types

type ExitCode

type ExitCode int

ExitCode :: alias for exitcode

type InteractiveExitStatus

type InteractiveExitStatus struct {
	// TODO remove altogether
	ExitCode int
}

InteractiveExitStatus :: exist status from the interative prompt

We exit go-prompt after every query (in order to manage the prompt history to only include complete queries) We therefore need to distinguish between:

a user requested exit (ctrl+D or .exit) - indicated by a non-nil exit code and restart=false and a value , go-prompt being terminated after a query completion and requiring restarting - indicated by restart=true

type Semaphore added in v0.17.0

type Semaphore struct {
	// contains filtered or unexported fields
}

Semaphore is a struct wrapping a sema`phore thast makes it easier to debug deadlocvks and failures to release
