Functions

func ContainsInt

func ContainsInt(needle int, haystack []int) bool

func GetNKeyValuePairsStringMap

func GetNKeyValuePairsStringMap(kvd map[string]string) int

GetNKeyValuePairsStringMap returns the number of key-value mappings stored in the provided `kvd` (key-value dictionary)

func IsPathType

func IsPathType(pathInfo os.FileInfo, pathType PathType) bool

func PathExists

func PathExists(asType PathType, pathFragments ...string) (bool, error)

func ResolvePath

func ResolvePath(relativePathFragments ...string) (string, error)

func Untar

func Untar(options UntarOptions) []error

Untar takes the .zip file located at options.InputPath and untars its contents to options.OutputPath; returns an error if something unexpected happened, or nil if all is well

Made possible with guidance from: https://medium.com/@skdomino/taring-untaring-files-in-go-6b07cf56bc07

func Unzip

func Unzip(options UnzipOptions) []error

Unzip takes the .zip file located at options.InputPath and unzips its contents to options.OutputPath; returns an error if something unexpected happened, or nil if all is well

Made possible with guidance from: https://golangcode.com/unzip-files-in-go/

Types

type PathType

type PathType string

func (PathType) String

func (pt PathType) String() string

type UntarEvent

type UntarEvent struct {
	// State is a string code that indicates the underlying operation
	State UntarState
	// Path is a string indicating path to a file if it's non-empty
	Path string
	// Message is an arbitrary string
	Message string
	// Status should provide metadata on the underlying operation
	Status *UntarStatus
}

UntarEvent is an object that is passed to the events stream for the consumer to know what's going on inside

type UntarOptions

type UntarOptions struct {
	// Events, if populated, receives events for logging purposes
	Events chan UntarEvent
	// InputPath defines the path to the .zip file we want to untar
	InputPath string
	// OutputPath defines the path to a directory where the untarred files
	// should go
	OutputPath string
	// ReturnOnFileError indicates whether to return an error instantly
	// when an error is encountered
	ReturnOnFileError bool
}

type UntarState

type UntarState string

const (
	UntarStateStarting   UntarState = "untar_starting"

type UntarStatus

type UntarStatus struct {
	// BytesTotal is the total number of bytes to extract
	BytesTotal int64
	// BytesProcessed is the number of bytes processed so far
	BytesProcessed int64
	// FilesTotalCount is the total number of files to extract
	FilesTotalCount int
	// FilesProcessedCount is the number of files processed so far
	FilesProcessedCount int
}

UntarStatus stores the status of the untarring process and is returned through the UntarEvent object

	// Message is an arbitrary string
	Message string
	// Status should provide metadata on the underlying operation
	Status *UnzipStatus
}

UnzipEvent is an object that is passed to the events stream for the consumer to know what's going on inside

type UnzipOptions

	BytesProcessed int64
	// FilesTotalCount is the total number of files to extract
	FilesTotalCount int
	// FilesProcessedCount is the number of files processed so far
