Hello,

I have code which uses Text.Printf.printf with String. Now I'm moving the code to use strict Text everywhere (I picked strict since all my strings are very short, mostly less than 400 chars). What should I use instead of printf now?

One solution I found is the text-format package, which seems to simply split a Text on occurences of "{}" and insert values there. Are there other simple and efficient options? All I need is to append Text values and sometimes Ints too, so it's enough to have

(1) efficient append and concat (2) A function that is :: Int -> Text

Why is strict Text not a Monoid instance? And Builder has no `toStrictText` function? There is a function to convert Int to Builder and a Buildable instance for Int, but for a simple Int->Text it seems I'm left with an ugly `T.pack . show`.

Suggestions / advice / comments on this?

Thanks in advance :)

Since Text does have a Monoid instance after all, another question: The docs say 'append' is subject to fusion, but it isn't said about 'concat'. When I need to append several texts together, does it matter whether I just use <> between then or I 'concat' a list of them? Any one of them recommended / more efficient? I don't have any performance issues in my program, I just want to create good habits now and not get used to bad ones :P --fr33
