func Filter

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

Filter returns a new slice only containing the elements for which invoking the predicate returned true

The predicate is invoked with each element

func FindProcess

func FindProcess(targetPid int) (*psutils.Process, error)

FindProcess tries to find the process with the given pid returns nil if the process could not be found

func GetMD5Hash

func GetMD5Hash(text string) string

func HandleCancelError

func HandleCancelError(err error) error

func IsPortBindable(port int) error

func IsWSL

func IsWSL() (bool, error)

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 MergeStringMaps

func MergeStringMaps(old, new map[string]string) map[string]string

MergeStringMaps merges 'new' onto old. Any vakue existing in new but not old is added to old NOTE this mutates 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 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 PrefixError

func PrefixError(err error, prefix string) error

func RemoveDirectoryContents

func RemoveDirectoryContents(removePath string) error

func SafeIntEqual

func SafeIntEqual(i1, i2 *int) bool

func SafeStringsEqual

func ShowErrorWithMessage

func ShowErrorWithMessage(ctx context.Context, err error, message string)

ShowErrorWithMessage displays the given error nicely with the given message

func ShowWarning

func ShowWarning(warning string)

func SortedStringKeys

func SortedStringKeys[V any](m map[string]V) []string

func SplitByRune

func SplitByRune(str string, r rune) []string

Types

type ExitCode

type ExitCode int

ExitCode :: alias for exitcode

type FileWatcher

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

func NewWatcher

func NewWatcher(opts *WatcherOptions) (*FileWatcher, error)

}

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 LifecycleEvent

type LifecycleEvent struct {
	Event string
	Time  time.Time

type WatcherOptions struct {
	Directories []string
	Include     []string
	Exclude     []string
	OnChange    func([]fsnotify.Event)
