// - Sequence "ftp".
// - Sequence "io".
// - Sequence of digits.

Reverse returns reversed string
RightTrim trims characters from the right side of the input. If second argument is empty, it will remove trailing spaces.
RuneLength check string's length Alias for StringLength
SafeFileName returns safe string that can be used in file names
SetFieldsRequiredByDefault causes validation to fail when struct fields do not include validations or are not explicitly marked as exempt (using `valid:"-"` or `valid:"email,optional"`). This struct definition will fail govalidator.ValidateStruct() (and the field values do not matter):
type exampleStruct struct {
Name string ``
Email string `valid:"email"`
This, however, will only fail when Email is empty or an invalid email address:
type exampleStruct2 struct {
Name string `valid:"-"`
Email string `valid:"email"`
Lastly, this will only fail when Email is an invalid email address but not when it's empty:
type exampleStruct2 struct {
Name string `valid:"-"`
Email string `valid:"email,optional"`
SetNilPtrAllowedByRequired causes validation to pass for nil ptrs when a field is set to required. The validation will still reject ptr fields in their zero value state. Example with this enabled:
type exampleStruct struct {
Name *string `valid:"required"`
With `Name` set to "", this will be considered invalid input and will cause a validation error. With `Name` set to nil, this will be considered valid by validation. By default this is disabled.
Sign returns signum of number: 1 in case of value > 0, -1 in case of value < 0, 0 otherwise
StringLength check string's length (including multi byte strings)
StringMatches checks if a string matches a given pattern.
StripLow removes characters with a numerical value < 32 and 127, mostly control characters. If keep_new_lines is true, newline characters are preserved (\n and \r, hex 0xA and 0xD).
ToBoolean convert the input string to a boolean.
ToFloat convert the input string to a float, or 0.0 if the input is not a float.
ToInt convert the input string or any int type to an integer type 64, or 0 if the input is not an integer.
ToJSON convert the input to a valid JSON string
ToString convert the input to a string.
Trim trims characters from both sides of the input. If second argument is empty, it will remove spaces.
This small example illustrate how to work with Trim function.
Code:
// Remove from left and right spaces and "\r", "\n", "\t" characters println(Trim(" \r\r\ntext\r \t\n", "") == "text") // Remove from left and right characters that are between "1" and "8". // "1-8" is like full list "12345678". println(Trim("1234567890987654321", "1-8") == "909")
Truncate a string to the closest length without breaking words.
TruncatingErrorf removes extra args from fmt.Errorf if not formatted in the str object
UnderscoreToCamelCase converts from underscore separated form to camel case form. Ex.: my_func => MyFunc
ValidateMap use validation map for fields. result will be equal to `false` if there are any errors. s is the map containing the data to be validated. m is the validation map in the form:
map[string]interface{}{"name":"required,alpha","address":map[string]interface{}{"line1":"required,alphanum"}}
ValidateStruct use tags for fields. result will be equal to `false` if there are any errors. todo currently there is no guarantee that errors will be returned in predictable order (tests may to fail)
Code:
type Post struct {
Title string `valid:"alphanum,required"`
Message string `valid:"duck,ascii"`
AuthorIP string `valid:"ipv4"`
}
post := &Post{"My Example Post", "duck", "123.234.54.3"}
//Add your own struct validation tags
TagMap["duck"] = Validator(func(str string) bool {
return str == "duck"
})
result, err := ValidateStruct(post)
if err != nil {
println("error: " + err.Error())
}
println(result)
WhiteList removes characters that do not appear in the whitelist.
This small example illustrate how to work with WhiteList function.
Code:
// Remove all characters from string ignoring characters between "a" and "z"
println(WhiteList("a3a43a5a4a3a2a23a4a5a4a3a4", "a-z") == "aaaaaaaaaaaa")
ConditionIterator is the function that accepts element of slice/array and its index and returns boolean
CustomTypeValidator is a wrapper for validator functions that returns bool and accepts any type. The second parameter should be the context (in the case of validating a struct: the whole object being validated).
type Error struct {
Name string
Err error
CustomErrorMessageExists bool
// Validator indicates the name of the validator that failed
Validator string
Path []string
}Error encapsulates a name, an error and whether there's a custom error message or not.
Errors is an array of multiple errors and conforms to the error interface.
Errors returns itself.
