Perhaps tryhaskell.org matches what you're looking for? It comes with an interactive tutorial which might be a good place to start—or, if you want, I'm sure you could use it to set up your own tutorial just by changing the code. However, I think it's mainly interactive and doesn't support writing and loading modules.

It's a shame that paste.hskll.org is down, especially because it had support for the diagrams library.

Hi Cafe,

Does anyone know of a website where I can write a few lines of Haskell and have them run? Ideally, there would be a place to write a module and then a place to load the module into GHCi. I seem to recall something that fit my needs at paste.hskll.org, but that site is no longer working.

I'm asking because I'll be teaching an undergraduate course this fall in introductory Haskell. There are no prerequisites for the course, and my course roster suggests that I'll have several students with no programming background at all. (This is great, actually -- I love facilitating a new programmer's first steps!) It might be nice to get students off the ground quickly before bogging them down with installation details -- hence the website I'm looking for.

Thanks!
Richard
