Functions ¶
func Alpha ¶
Alpha returns only alpha characters. Set the parameter spaces to true if you want to allow space characters. Valid characters are a-z and A-Z.
View examples: sanitize_test.go
Example (NoSpaces) ¶
ExampleAlpha_noSpaces example using Alpha() and no spaces flag
fmt.Println(Alpha("Example String!", false))
Output: ExampleString
Example (WithSpaces) ¶
ExampleAlpha_withSpaces example using Alpha with spaces flag
fmt.Println(Alpha("Example String!", true))
Output: Example String
func AlphaNumeric ¶
AlphaNumeric returns only alphanumeric characters. Set the parameter spaces to true if you want to allow space characters. Valid characters are a-z, A-Z and 0-9.
View examples: sanitize_test.go
Example (NoSpaces) ¶
ExampleAlphaNumeric_noSpaces example using AlphaNumeric() with no spaces
fmt.Println(AlphaNumeric("Example String 2!", false))
Output: ExampleString2
Example (WithSpaces) ¶
ExampleAlphaNumeric_withSpaces example using AlphaNumeric() with spaces
fmt.Println(AlphaNumeric("Example String 2!", true))
Output: Example String 2
func Custom ¶
Custom uses a custom regex string and returns the sanitized result. This is used for any additional regex that this package does not contain.
View examples: sanitize_test.go
Example (Alpha) ¶
ExampleCustom_alpha example using Custom() using an alpha regex
fmt.Println(Custom("Example String 2!", `[^a-zA-Z]`))
Output: ExampleString
Example (Numeric) ¶
ExampleCustom_numeric example using Custom() using a numeric regex
fmt.Println(Custom("Example String 2!", `[^0-9]`))
Output: 2
func Decimal ¶
Decimal returns sanitized decimal/float values in either positive or negative.
View examples: sanitize_test.go
Example (Negative) ¶
ExampleDecimal_negative example using Decimal() for a negative number
fmt.Println(Decimal("$ -99.99!"))
Output: -99.99
Example (Positive) ¶
ExampleDecimal_positive example using Decimal() for a positive number
fmt.Println(Decimal("$ 99.99!"))
Output: 99.99
func Domain ¶
Domain returns a proper hostname / domain name. Preserve case is to flag keeping the case versus forcing to lowercase. Use the removeWww flag to strip the www sub-domain. This method returns an error if parse critically fails.
View examples: sanitize_test.go
Example ¶
ExampleDomain example using Domain()
fmt.Println(Domain("https://www.Example.COM/?param=value", false, false))
Output: www.example.com <nil>
Example (PreserveCase) ¶
ExampleDomain_preserveCase example using Domain() and preserving the case
fmt.Println(Domain("https://www.Example.COM/?param=value", true, false))
Output: www.Example.COM <nil>
Example (RemoveWww) ¶
ExampleDomain_removeWww example using Domain() and removing the www sub-domain
fmt.Println(Domain("https://www.Example.COM/?param=value", false, true))
Output: example.com <nil>
func Email ¶
Email returns a sanitized email address string. Email addresses are forced to lowercase and removes any mail-to prefixes.
View examples: sanitize_test.go
Example ¶
ExampleEmail example using Email()
fmt.Println(Email("mailto:Person@Example.COM", false))
Output: person@example.com
Example (PreserveCase) ¶
ExampleEmail_preserveCase example using Email() and preserving the case
fmt.Println(Email("mailto:Person@Example.COM", true))
Output: Person@Example.COM
func FirstToUpper ¶
FirstToUpper overwrites the first letter as an uppercase letter and preserves the rest of the string.
View examples: sanitize_test.go
Example ¶
ExampleFirstToUpper example using FirstToUpper()
fmt.Println(FirstToUpper("this works"))
Output: This works
func FormalName ¶
FormalName returns a formal name or surname (for First, Middle and Last)
View examples: sanitize_test.go
Example ¶
ExampleFormalName example using FormalName()
fmt.Println(FormalName("John McDonald Jr.!"))
Output: John McDonald Jr.

Output: This Works?
func IPAddress ¶
IPAddress returns an ip address for both ipv4 and ipv6 formats.
View examples: sanitize_test.go

fmt.Println(IPAddress(" 192.168.0.1 "))
Output: 192.168.0.1
Example (Ipv6) ¶
ExampleIPAddress_ipv6 example using IPAddress() for IPV6 address
fmt.Println(IPAddress(" 2602:305:bceb:1bd0:44ef:fedb:4f8f:da4f "))
Output: 2602:305:bceb:1bd0:44ef:fedb:4f8f:da4f
