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!"

Since 0.3.0
Combinator for the
<map> element.
Example:
map $ span $ toHtml "foo"
Result:
<map><span>foo</span></map>
Apply a function to all values flowing downstream
map id = cat
map (g . f) = map f >-> map g
Maps a pure function over an
InputStream.
map f s passes all output from
s through the
function
f.
Satisfies the following laws:
Streams.map (g . f) === Streams.map f >=> Streams.map g
Streams.map id === Streams.makeInputStream . Streams.read
