Functions

func CommonMiddleware

func CommonMiddleware(next http.Handler) http.Handler

CommonMiddleware --Set content-type

func DefaultErrorHandler

func DefaultErrorHandler(w http.ResponseWriter, status int)

func EnsureDir

func EnsureDir(fileName string) bool

EnsureDir checks a file could be written to a path, creates the directories as needed

func ErrorLog

func FileExists

func FileExists(filePath string) bool

FileExists returns whether a file exists

func GPFiles

func GPFiles(p string) (s []string)

GPFiles reads in the list of template files

func GetIP

func GetIP(s string) (ip, port string)

GetIP reads an IP from a string (this doesn't look to me like it is correctly written)

func GetJSON

func GetJSON(completeURL string) (interface{}, error)

GetJSON reads a JSON file and returns an map containing the parsed data

func InsertFloat

func InsertFloat(i interface{}) (f float64)

func InsertString

func InterceptHandler

func InterceptHandler(next http.Handler, errH ErrorHandler) http.Handler

func MakeSlug

func MakeSlug(text string) string

MakeSlug slugifies a string. The result will only contain lowercase letters, digits and dashes. It will not begin or end with a dash, and it will not contain runs of multiple dashes.

It is NOT forced into being ASCII, but may contain any Unicode characters, with the above restrictions.

func SHA384

func SHA384(filename string) string

func Truncate

func Truncate(s string, l int) string
