C# Class FP.Text.Strings

Provides a set of static (Shared in Visual Basic) methods for strings.
The source of each method includes the Haskell version as a comment at the end. Some methods are not safe to use with mutable collections. These cases are mentioned in the documentation for the method. The order of arguments has generally been inverted compared to the Haskell versions to facilitate method chaining. See also the Remarks for Enumerable.

Public Methods

Method Description
AsString ( this charSequence ) : string

Converts a sequence of chars to a string. This should be called ToString, but this is impossible for the obvious reason.
Clear ( this sb ) : void

Clears the specified StringBuilder. This is equivalent to calling sb.Count = 0.
IsNullOrEmpty ( this s ) : bool

Determines whether the string is null or empty. This is merely string.IsNullOrEmpty(s) as an extension method.
Lines ( this charSequence ) : IEnumerable

Breaks the specified char sequence into a sequence of strings at newline characters. The resulting strings do not contain newlines.
ReverseIterator ( this s ) : IEnumerable

Enumerates the specified string in the reverse order.
UnLines ( this lines ) : IEnumerable

An inverse to Lines. Joins lines, after appending a terminating newline to each.
UnLinesAsString ( this lines ) : string

Equivalent to UnLines().AsString(), but more efficient.
UnLinesCS ( this lines ) : IEnumerable

An inverse to Lines. It joins lines, after appending a terminating newline to each.
UnWords ( this words ) : IEnumerable

An inverse to Words. It joins words, separating them by a single space.
UnWordsAsString ( this words ) : string

Equivalent to UnWords().AsString(), but more efficient.
UnWordsCS ( this words ) : IEnumerable

An inverse to Words. It joins words, separating them by a single space.
Words ( this charSequence ) : IEnumerable

Breaks the specified char sequence into a sequence of words delimited by whitespace. The resulting strings do not contain whitespace.

Method Details

AsString() public static method

Converts a sequence of chars to a string. This should be called ToString, but this is impossible for the obvious reason.
public static AsString ( this charSequence ) : string
charSequence this The char sequence.
