Re: Semigroup repeat (base package)

Indeed it is cycle1, sorry to have missed it. It will be easier to spot it if it close to the stimes* functions in the beginning of the docs. It is placed too far down below even after Monoid re-exports. -harendra On 10 September 2017 at 14:09, Herbert Valerio Riedel wrote:

I could not find a function that repeats a value using a semigroup append. I am looking for something like this:

srepeat :: Semigroup a => a -> a srepeat x = xs where xs = x <> xs

Is it already available somewhere? Does it make sense to add it to Data.Semigroup?

What you seem to be searching for looks more like what we know as `cycle :: [a] -> [a]`, and in fact there is its generalisation at
