Map a function over all values in the map.
Combinator for the
<map> element.
Example:
map $ span $ toHtml "foo"
Result:
<map><span>foo</span></map>
O(n) map f xs is the ByteString obtained by
applying
f to each element of
xs.
O(n) map f xs is the ByteString obtained by
applying
f to each element of
xs
O(n) map f xs is the ShortByteString obtained
by applying
f to each element of
xs.
Transform the original string-like value but keep it case insensitive.
Apply function to every element of matrix
O(n) map f xs is the OsString obtained by
applying
f to each element of
xs.
O(n) map f xs is the ShortByteString obtained
by applying
f to each element of
xs.
O(n) map f xs is the OsString obtained by
applying
f to each element of
xs.
O(n) map f xs is the OsString obtained by
applying
f to each element of
xs.
Apply a function to all values flowing downstream
map id = cat
map (g . f) = map f >-> map g
O(n) Modify every value in the queue.
O(n) Modify every value in the queue.
O(n) Modify every value in the queue.
O(n) map f t is the
Text
obtained by applying
f to each element of
t.
Example:
>>> let message = pack "I am not angry. Not at all."
>>> T.map (\c -> if c == '.' then '!' else c) message
"I am not angry! Not at all!"
Performs replacement on invalid scalar values.
