Functions

func EscapeJoin

func EscapeJoin(elems []string, sep string) string

EscapeJoin acts like strings.Join, except it first escapes elements via net/url

func ExecuteTemplate

func ExecuteTemplate(tmpl *template.Template, data any) (string, error)

ExecuteTemplate executes the given text template with the given data, and returns the resulting string.

func RandomHash

func RandomHash() string

RandomHash returns a 64 hex character random string

func SingleWordCamel

func SingleWordCamel(w string) string

SingleWordCamel takes a single word and returns is in Camel case; basically just capitalizing the first letter and making sure the rest are lower case.

func SplitDelimitedList

func SplitDelimitedList(s string) (list []string)

SplitDelimitedList splits a given string by comma, semi-colon or space, and returns non-empty strings

func SplitUnescape

func SplitUnescape(s string, sep string) ([]string, error)

SplitUnescape acts like strings.Split, except it then unescapes tokens via net/url

func Title

func Title(s string) string

Title returns a copy of the string s with all Unicode letters that begin words mapped to their Unicode title case.

This is a simplified version of `strings.ToTitle` which is deprecated as it doesn't handle all Unicode characters correctly. But we don't care about those, so we can use this. This avoids having all of `x/text` as a dependency.

func UUIDv5

func UUIDv5(inputs ...string) string

UUIDv5 creates a UUID v5 string based on the given inputs. We use a SHA256 algorithm. Return format is textual

func UUIDv5Base36

func UUIDv5Base36(inputs ...string) string

UUIDv5Base36 creates a UUID v5 string based on the given inputs. Return value is a 25 character, base36 string

func UUIDv5Val

func UUIDv5Val(inputs ...string) big.Int

UUIDv5Val creates a UUID v5 string based on the given inputs. Return value is a big.Int

func ValueIsSimulatedNull

func ValueIsSimulatedNull(val any) bool

ValueIsSimulatedNull returns true if the value represents a NULL or unknown/unspecified value. This is used to distinguish between a zero value / default and a user provided value that is equivalent (e.g. an empty string or slice).
