Summary

Check whether the expected (e) widget is in the slice (s) of widgets.

Prevent special CSV characters ("," and ";") from splitting a column.

Repeat a character (typically used for simple formatting of output).

Copy makes a recursive deep copy of obj and returns the result.

FileExists returns true if the file exists.

Check whether the expected (e) string is in the slice (s) of stings.

Iif_string is and immediate if helper that takes a boolean expression and returns a string, true_val if the expression is true else false_val.

Find index of search string in target string, starting at startPos Ex: domain := email[IndexOf("@", email, 0)+1:].

IndexOfGeneric returns the index of an element in any type of slice ints := []int{1, 2, 3} strings := []string{"A", "B", "C"} IndexOfGeneric(len(ints), func(i int) bool { return ints[i] == 2 }) IndexOfGeneric(len(strings), func(i int) bool { return strings[i] == "B" }).

Check whether the expected (e) int is in the slice (s) of ints.

reflect doesn't consider 0 or "" to be zero, so we double check those here Can handle a struct field (only one level).

Assumes the argument is not a struct.

Assumes the argument is a struct.

Printf("isLower(\"a\"): %v\n", isLower("a")) // isLower("a"): true Printf("isLower(\"A\"): %v\n", isLower("A")) // isLower("A"): false.

Concat joins the strings in a slice, delimiting them with a comma, but it allows you to pass the delimiter string to create a single string Ex: data: []string{"A", "B", "C"}; Join(data) ==> "A,B,C" ; Join(data, "|") ==> "A|B|C".

LengthOf returns the number if items in argument.

NewSingleton is a singleton object which restricts object creation to only one instance.

PadLeft pads a string (s) with with a specified string (optional parameter) for padLen characters If no string argument is passed, then s will be padded, to the left, with a single space character.

PadRight pads a string (s) with with a specified string (optional parameter) for padLen characters If no string argument is passed, then s will be padded, to the right, with a single space character.

A: 65 B: 66 .

QueryString takes an http request object and returns its query string.

Check whether the expected (e) string is in the slice (s) of stings.

Substr returns a portion (length characters) of string (s), beginning at a specified position (pos).

ToCurrency converts the value to a dollar and cents string.

ToFloat converts the argument to a float64 throws panic if argument is non-numeric parameter.

ToInt64 converts the argument to a int64 throws panic if argument is non-numeric parameter.

ToString converts the value to a string.

ToTS converts the value to a timestamp string (accepts both time.Time and *time.Time as argument).

ToUnsignedInteger converts the argument to a uint64 throws panic if argument is non-numeric parameter.

TypeOf returns the reflection Type of the value in the interface{}.
