How to print comma-separated list with hamlet?

由 Deadly 提交于 2020-01-03 12:37:15
问题 With the hamlet templating language that comes with yesod, what is the best way of printing a comma-separated list? E.g. assume this code which just prints one entry after another, how do I insert commas in between the elements? Or maybe even add an “and” before the last entry: The values in the list are $ forall entry <- list #{entry} and that is it. Some templating languages such as Template Toolkit provide directives to detect the first or last iteration. 回答1: I don't think there's

Yesod's shakespearean templates (hamlet) and IO

由 痞子三分冷 提交于 2019-12-20 02:28:32
问题 In Hamlet, how does one uses the result of an IO operation inside #{...} ? For instance : someIO :: IO String ----------------- $with stuff <- someIO <p>#{stuff} Fails with No instance for (blaze-markup-0.6.0.0:Text.Blaze.ToMarkup (IO String)) arising from a use of `toHtml' I fear that I have not approached the problem from the right angle, could someone shed some light on this issue for me? Thank you 回答1: Hamlet is just providing an alternate syntax for normal Haskell code, so like normal

I'm working in a Haskell Yesod site for college on a C9 workspace, I've already installed by command Yesod and update cabal, but when I try "stack build" command, this miserable error message appears: $ stack build aulahaskell-0.0.0: build (lib + exe) Preprocessing library aulahaskell-0.0.0...

Rendering static HTML with hamlet

由 ◇◆丶佛笑我妖孽 提交于 2019-12-10 16:33:43
问题 How can I use the hamlet framework to generate static HTML pages from inside Haskell? Note: This question intentionally doesn't show research effort. For my research effort, see the Q&A-style answer below. 回答1: hamlet yields QuasiQuoters that are evaluated to blaze expressions. Using Text.Blaze.Html.Renderer.String.renderHtml you can render them to a string. Let's start with a simple non-HTML example: {-# LANGUAGE QuasiQuotes #-} import Text.Blaze.Html.Renderer.String (renderHtml) import Text
