Functions ¶
func AddDays ¶
AddDays adds the given number of days to the given date. The number of days can be negative.
func AllFilesUnderDir ¶
AllFilesUnderDir returns a list of all filenames that exist under the supplied directory. If the supplied directory does not exist then it returns an empty list.
func CopyFile ¶
func CopyFile(fromPath, toPath, label string)
CopyFile copies a given file. alert.Exit on failure (via WriteFile)
func DaysBetween ¶
DaysBetween returns the number of days between the two dates. Remember that the difference between a date and itself is zero.
func ExecPath ¶
func ExecPath() string
ExecPath returns a string containing the full executable path.
func F32toa ¶
F32toa converts a float32 into a string. This is simply a convenience wrapper around `strconv.FormatFloat`.
func F64toa ¶
F64toa converts a float64 into a string. This is simply a convenience wrapper around `strconv.FormatFloat`.
func FileExists ¶
FileExists return true of the supplied filename exists
func Hostname ¶
func Hostname() string
Hostname returns a string containing the hostname. Returns the value "unknown_host" on failure
func InTimeRange ¶
InTimeRange returns true if the first time is between the second and third times inclusive
func MakeDate ¶
MakeDate converts a date in literal-integer format (i.e. 2015-06-01 is represented by the integer 20150601) to a time.Time value in the local timezone.
func MakeDateI ¶
MakeDateI converts a date in literal-integer format (i.e. 2015-06-01 is represented by the integer 20150601) to a time.Time value in the local timezone.
func MakeDateList ¶
MakeDateList returns a list of consecutive dates starting and ending on the given dates (inclusive)
func MakeDateS ¶
MakeDateS converts a date from string formats "2015-06-01" and "20150601" to a time.Time value. The time will be midnight UTC.
func ParseFloat64 ¶
ParseFloat64 parses a string and returns a float64. On failure it displays an error message and calls exit.
func ParseUint32 ¶
ParseUint32 parses a string and returns a uint32. On failure it displays an error message and calls exit.
func ReadYAML ¶
func ReadYAML(filename string, config interface{})
ReadYAML reads a YAML file into an arbitrary structure.
func SideBySide ¶
SideBySide takes two (multi-line) strings and returns a string that displays them side by side:
Apple Pear Banana Grapefruit Canteloupe
They do not have to have the same number of lines
func StackTrace ¶
StackTrace returns a string containing stack-trace information up to the supplied depth. Supplying a depth of zero results in a full stack-trace.
func StripColors ¶
StripColors returns a string by removing color-coding characters from the supplied string
func SubDays ¶
SubDays subtracts the given number of days to the given date. The number of days can be negative.
