Functions ¶
func Abort ¶
func Abort(err error)
Abort does nothing if err is nil, otherwise logs the error and exits
func AbortWithString ¶
func AbortWithString(msg string)
func BigEndianUint32 ¶
func BigEndianUint64 ¶
func BoolFromQuery ¶
BoolFromQuery return false if query is missing or set to false
func BytesToString ¶
func CloneStringSlice ¶
func DefaultToExecutable ¶
Default to executable returns full path. If input path is relative, it will considered relative to the the folder of the executable
func DivideRoundUp ¶
func DownloadFile ¶
DownloadFile will download a file from a url. Assumes that url is a file download url
func EraseString ¶
func FileExists ¶
func FileSizeString ¶
func GetTempFile ¶
func InitLogging ¶
func InitLogging(filePath string)
InitLogging initializes a rotating logger. This should be done once by the executable filePath is the full path of the log file
func InvalidArgs ¶
func InvalidArgs(msg string)
func IsFullPath ¶
func IsLegalFilePath ¶
IsLegalFilePath checks for forbidden characters
func IsLegalUserName ¶
IsLegalUserName checks for forbidden characters
func MakeFolders ¶
func MakeStringOfLen ¶
func PromptForInput ¶
PromptForInput prompts on stdin and reads a line. Empty string is returned on error
func Rewind ¶
func Rewind(r io.ReadSeeker)

func SetLoggingLevelFromName ¶
func SetLoggingLevelFromName(level string)
func StringKeysOf ¶
func StringToBytes ¶
func StringToEthAddress ¶
func ToJsonString ¶
func ToJsonString(data interface{}) string
func WriteLastLines ¶
WriteLastLines writes the last numLines from filepath to w
func WriteTempFile ¶
WriteTempFile writes from the reader to a temp file and returns the path of the file or an empty string on error
Types ¶
