for example for lists []

map :: (a -> b) -> [a] -> [b]

and for Maybe

map :: (a -> b) -> Maybe a -> Maybe b

It is not immediately obvious how to use the play console so this might help.

Play2 provides an equivalent of the rails console you might be used to.

Use

cd myapp
play console

Notes about your presentation draft

As kindly requested :)

• http://aurelien.thier.io/casperjs-ghost-tour/#selectors: you should mention the import of var x = require('casper').selectXPath
• on the same slide, it probably misses a run() final call
• http://aurelien.thier.io/casperjs-ghost-tour/#evaluates: you may want to mention the remoteScripts option as well
• on the same slide, this.test.assertEval(function(title)}, 'google.fr title is "Google"', 'Google'); should be this.test.assertEval(function(title)}, 'Google', 'google.fr title is "Google"');
• http://aurelien.thier.io/casperjs-ghost-tour/#debug: you should mention the existence of a bookmarklet
• http://aurelien.thier.io/casperjs-ghost-tour/#more: maybe add the link to the casperjs github org listing its whole ecosystem: https://github.com/casperjs

#Play2 : Les Iteratees expliqués aux humains... francophones!

Disclaimer : Ce qui suit est la traduction d'un article anglophone paru sur le blog mandubian.com

Vous pouvez retrouver l'article original ici

Vous avez probablement remarqué une nouvelle fonctionnalité intrigante de Play2 nommée Iteratee (ainsi que ses compagnons Enumerators et Enumeratee). Le but de cet article est d'essayer de rendre le concept d'Iteratee compréhensible pour le plus grand nombre avec des arguments simples, en évitant l'approche mathématique / fonctionnelle.

Cet article ne prétend pas tout expliquer à propos des Iteratee / Enumerator / Enumeratee mais traite plutôt les idées qui se cachent derrière.
