Replication

replicateA :: Series m Text

["","a","aa","aaa","aaaa"]

Use this when you don't care about the Chars inside Text.

replicateNull :: Series m Text

A Text Series that grows by replicating the NUL Char.

>>> list 4 replicateNull
["","\NUL","\NUL\NUL","\NUL\NUL\NUL","\NUL\NUL\NUL\NUL"]

replicateChar :: Char -> Series m Text

A Text Series that grows by replicating the given Char.

>>> list 4 $ replicateChar '☃'
["","\9731","\9731\9731","\9731\9731\9731","\9731\9731\9731\9731"]

Enumeration

enumAlphabet :: Series m Text

A Text Series that grows by enumerating the latin alphabet.

>>> list 4 enumAlphabet
["","a","ab","abc","abcd"]

enumChars :: Series m Text

A Text Series that grows by enumerating every Char.

>>> list 4 enumChars
["","\NUL","\NUL\SOH","\NUL\SOH\STX","\NUL\SOH\STX\ETX"]

enumString :: String -> Series m Text

A Text Series that grows by enumerating every Char in the given String. Notice that the String can be infinite.

>>> list 5 $ enumString "xyz"
["","x","xy","xyz"]

Printing

jack :: Series m Text

A Text Series that grows with English words.

This is useful when you want to print Series.

>>> let s = list 20 jack
>>> take 3 s
["","All","All work"]
>>> last s
"All work and no play makes Jack a dull boy. All work and no play makes Jack a dull boy."

Extra Unicode planes

enumNonBmp :: Series m Text

A Text Series that grows with the first character of each Unicode plane.

>>> list 3 enumNonBmp
["","\NUL","\NUL\65536","\NUL\65536\131072"]

Notice that this covers the 16 unicode planes.

>>> last (list 16 enumNonBmp) == last (list 17 enumNonBmp)
True
