Folks, I have finished an alpha version of my EasyLanguage [1] to C# compiler and need to deploy it on Amazon EC2/S3. The compiler web interface is very simple: paste EL code, get back C# code or the same EL code with the error highlighted. I view the site as more than just a compiler, though, and want a blog, forums, etc. Last but not least, I want to be able to update portions of the site without shutting it down. My choice seems to boil down to HAppS [2], HOPE [3], or a combination of Ruby/Rails with Lambdabot. At first glance, HAppS lacks publishing (my ultimate need) but promises an interface to S3 sometime in the future. My understanding is that it's ready but is not being released. HAppS is heavy on features that I may not make use of. I had a hard time understanding the HPaste [4] code written using HAppS and I don't fancy using XSLT as my HTML template language. HOPE has a publishing framework (blog, RSS, comments). I could write the forums or just use Google Groups. I like the module system and the FCGI interface should let me couple HOPE with Lighty [5]. The HOPE code base looks clean and simple and I'm guessing that adding Lambdabot-style dynamic loading of modules would be straightforward. Overall, HOPE has everything that I need, without unnecessary extras. It does not have an interface to Amazon S3, though, and I would need that to rewrite the storage bits to use S3 instead of a regular database. Lambdabot by itself doesn't offer much apart from robust dynamic loading of Haskell code. Its features have been heavily tested, though, which gives me a warm feeling. I'm thinking that the same hot- loading technology that Lambdabot uses could be coupled with either HAppS or HOPE. Lambdabot has a FCGI which should make mixing it with HOPE particularly easy. Going with Ruby and Rails I will have everything I need and more. The compiler could run in a separate server (think Lambdabot) but I would need to manage two different platforms. Is my assessment correct? Did I miss anything? What approach do you favor? Thanks, Joel P.S. I have the same compiler written in OCaml which is what I started with. Developing it has been a relative breeze but deploying on the web was a tale of frustration. I gave up and finished the Haskell version.
