String

length

$string.length

Property. Character length of the string.

uppercase

$string.uppercase

Property. A string based on the original with an uppercase transformation.

lowercase

$string.lowercase

Property. A string based on the original with a lowercase transformation.

split

$string.split()

Returns a list of substrings based on the division of the original string by the provided separator.

• optional separator: Str | Rgx - Substring separator. The default is the empty string, which results in a list of individual characters.

• optional limit: Num - Number of substrings to extract. If specified, the returned list will have at most this number of strings. The final string in that list may include occurrences of the separator.

fill

$string.fill()

Returns a string based on the original string with placeholders within the delimiters << and >> replaced with the provided values.

This method takes named arguments whose values should be strings or objects capable of string conversion.

.fill() will also respect indentation. If the provided values are multi-line, they will be indented at the same depth as the placeholder.

For example, "Hi <<name>>!".fill(name: "Steve") returns "Hi Steve!".

• optional valueHash: Hash - If provided, the keys and values in this hash will be used to fill the placeholders rather than the named argument pairs.

hasPrefix

$string.hasPrefix($prefix: Str)

Returns a boolean true value if the prefix exists.

• prefix: Str - Prefix to look for.

trimPrefix

$string.trimPrefix($prefix: Str)

Returns a string with the provided substring removed from the beginning (left side) of the original string. If the string does not have that prefix, a copy of the original string is returned.

• prefix: Str - Prefix to remove.

hasSuffix

$string.hasSuffix($suffix: Str)

Returns a boolean true value if the suffix exists.

• suffix: Str - Suffix to look for.

trimSuffix

$string.trimSuffix($suffix: Str)

Returns a string with the provided substring removed from the end (right side) of the original string. If the string does not have that suffix, a copy of the original string is returned.

• suffix: Str - Suffix to remove.

NonEmpty

An interface to which only non-empty strings comply.

In order to comply, the object must satisfy each of the following conditions.

1. isa: Must be an instance of Str.
2. satisfies: The string length is not zero (.length != 0).

Uppercase

Performs an uppercase transformation.

In order to comply, the object must satisfy each of the following conditions.

1. isa: Must be an instance of Str.
2. transform: The string transforms to an uppercase version (.uppercase).

Lowercase

Performs a lowercase transformation.

In order to comply, the object must satisfy each of the following conditions.

1. isa: Must be an instance of Str.
2. transform: The string transforms to an lowercase version (.lowercase).
