String.count(String) -> Integer
Returns the number of UTF-8 codepoints in the string.
String.lower(String) -> String
Converts all the characters of the string to lowercase.
String.upper(String) -> String
Converts all the characters of the string to uppercase.
String.capitalize(String) -> String
Capitalize the string to title case. All the first characters of words will be uppercase.
String.capitalize("hello world") // "Hello World"String.trim(String, subset String) -> String
Removes all the characters from subset from the start and end of the string.
String.trim("!@hello@!", "!@") // "hello"String.trimLeft(String, subset String) -> String
Removes all the characters from subset from the start of the string.
String.trimRight(String, subset String) -> String
Removes all the characters from subset from the end of the string.
String.reverse(String) -> String
Reverses the characters of the string.
String.reverse("hello") // "olleh"String.replace(String, search String, replace String) -> String
Replaces replace with search in the string.
String.replace("hello", "ll", "LL") // "heLLo"String.slice(String, start Integer, length Integer) -> String
Returns a substring from start with length length.
String.slice("hello", 2, 3) // "llo"String.join(Array, glue String) -> String
Joins an array with glue into a string.
String.join(["hello", "world"], " beautiful ") // "hello beautiful world"String.split(String, separator String) -> Array
Splits a string by separator into an array.
String.split("hello world", " ") // ["hello", "world"]String.first(String) -> String
Returns the first character of the string.
String.last(String) -> String
Returns the last character of the string.
String.contains?(String, search String) -> Boolean
Checks if the string contains search.
String.contains?("hello", "ll") // trueString.starts?(String, prefix String) -> Boolean
Checks if the string starts with prefix.
String.ends?(String, suffix String) -> Boolean
Checks if the string ends with suffix.
String.match?(String, regex String) -> Boolean
Checks if the string matches a PCRE-compatible regular expression.
String.match?("123", "[a-z]+") // trueEnum.size(Array|String) -> Integer
Returns the number of elements in the enumerable.
Enum.empty?(Array|String) -> Boolean
Checks if the enumerable is empty.
Enum.contains?(Array|String, search Any) -> Boolean
Checks if the enumerable contains an element search.
Enum.contains?(["hello", "world"], "hello") // trueEnum.reverse(Array|String) -> Array
Reverses the elements of the enumerable.
Enum.reverse([1, 2, 3]) // [3, 2, 1]Enum.first(Array|String) -> Any
Returns the first element of the array.
Enum.last(Array|String) -> Any
Returns the last element of the array.
Enum.insert(Array, value Any) -> Array
Insert value at the end of the array.
Enum.insert([1, 2], 3) // [1, 2, 3]Enum.delete(Array, index Integer) -> Array
Delete an element at index index.
Enum.random(Array|String) -> Any
Returns a random element from the array.
The function that calculates the random index is not cryptographically secure, if that matters.
Enum.random(1..100)Enum.unique(Array|String) -> Array
Removes all duplicate values from the array.
Enum.unique([0, 1, 1, 2, 3]) // [0, 1, 2, 3]Enum.map(Array|String, fn Function(element)) -> Array
Maps function fn to every element of the array.
The element parameter represents the array element in iteration.
Enum.map([1, 2, 3], (x) -> x * x) // [1, 4, 9]Enum.reduce(Array|String, start Any, fn Function(element, accumulator)) -> Any
Maps function fn to every element of the array, accumulating the start value.
element is the array element in iteration and accumulator the accumulated value.
Enum.reduce([1, 2, 3], 0, (x, acc) -> x + acc) // 6Enum.filter(Array|String, fn Function(element)) -> Array
Keeps every element of the array for which the function fn returns true.
element is the array element in iteration.
Enum.filter(1..10, (x) -> x % 2 == 1) // [1, 3, 5, 7, 9]Enum.find(Array|String, fn Function(element)) -> Any
Returns the first element for which the function fn returns true.
This is a shortcut to running: Enum.first(Enum.filter(...))
element is the array element in iteration.
Enum.find("abac", (x) -> x == "b") // "b"Dict.size(Dictionary) -> Integer
Returns the number of elements in a dictionary.
Dict.contains?(Dictionary, key String) -> Boolean
