`strreverse(X;Y)`

Returns the characters, or the elements delimited by a particular value, of a given string in reverse.

Syntax

strreverse(X;Y)
bstrreverse(X;Y)

Input

Argument	Type	Description
`X`	text	The string on which to apply the function A scalar value or the name of a column
`Y`	text	The character or string to be used as the delimiter in `X` A scalar value or the name of a column

Return Value

If Y is empty, the function returns the text value corresponding to the reversed characters of the string X. Otherwise, it splits string X using Y as a delimiter and returns a text value corresponding to a reversed, delimited list of the elements.

If X is N/A, the result is N/A. If Y is N/A, the result is a character-by-character (rather than element-by-element) reversal of X.

Sample Usage


`value`	`delimiter`	`strreverse(value;delimiter)`
'apple,banana,cherimoya'	','	'cherimoya,banana,apple'
'foo<>bar<>baz'	'<>'	'baz<>bar<>foo'
'foo<>bar<>baz'	''	'zab><rab><oof'

Additional Information

strreverse is Unicode (UTF-8) compliant and will work with Unicode or plain ASCII text fields.
If passed a string argument that is not legal Unicode, it will by default signal an error (configurable as a user preference).
A corresponding function bstrreverse can be used with non-Unicode strings (e.g., binary or legacy encodings).
