Functions

func Contains

func Contains[T comparable](list []T, val T) bool

Contains returns true if the provided list has a matching element

func ContainsAll

func ContainsAll(str string, terms []string) bool

ContainsAll returns true if all of the provided search terms are a substring of 'str'

func ContainsAny

func ContainsAny(str string, terms []string) bool

ContainsAny returns true if any of the provided search terms are a substring of 'str'

func FileExists

func FileExists(path string) (bool, error)

FileExists checks if a file *of any type* is present at the given path

func GetArchAliases

func GetArchAliases() []string

GetArchAliases returns all commonly used names for the system's architecture. ie - An 'amd64' system is functionally equivalent to 'x86_64' for our purposes

func GetFedoraGPGKeys

func GetFedoraGPGKeys() (io.ReadCloser, error)

func GetLineInFileMatchingKey

func GetLineInFileMatchingKey(filepath string, key string) (res string, err error)

GetLineInFileMatchingKey searches the provided file for a line that contains the provided key. A key is a pattern that will be either at the begin/end of line and will have ::spaces:: characters around. If a match is found, the entire line is returned. Only the first result is returned. If no lines match, an error is returned

func GetLineInReader

func GetLineInReader(reader io.Reader, match string) (res string, err error)

GetLinInReader searches the provided reader for a line that contains the provided string. If a match is found, the entire line is returned. Only the first result is returned. If no lines match, an error is returned

func GetOSAliases

func GetOSAliases() []string

GetOSAliases returns all commonly used names for the system's OS. ie - A system running 'darwin' is functionally equivalent to 'mac' for our purposes

func Keys

func Keys[T, U comparable](myMap map[T]U) []T

Keys returns a slice containing the keys of the provided map. Order is preserved

func Sha256sum

func Sha256sum(filepath string) (string, error)

Checksum reads the file at the provided path and calculates the sha256sum

func Unarchive

func Unarchive(source string, destination string) error

Unarchive decompresses and extracts the contents of .tar.gz bundles to the specified destination

func Unzip

func Unzip(source string, destination string) error

Unzip extracts files from a zip archive to the specified destination directory.

func VerifyGPGSignature

func VerifyGPGSignature(targetFilePath, signatureFilePath string) error

func WriteFile

func WriteFile(from io.Reader, to string, permissions os.FileMode) error

WriteFile creates a new file using the contents provided ('from') at the path provided ('to')
