F# from your browser

Be sure to check out the content on the Learn pages [1], which present a structured introduction to various aspects of the language (as opposed to the blank slate of the Create page). The examples really show off what you can do with F#, even in the browser environment (type providers with IntelliSense, charting, etc.).

  That's the first thing I did and that is what makes this an impressive offering. The smoothness of the introduction is very well done and you can easily see how it slowly introduces a novice, which you can easily skip as a more experienced dev because of how well it is structured. A difficult challenge which they've pulled off well.

The Intellisense doesn't seem to work for me. Ctr-Space brings up the dialog which just contains "Loading..."

I can't help notice some similarity in name and motivation to http://tryclj.com http://tryclj.com . http://www.tryfsharp.org/Help http://www.tryfsharp.org/Help 404s for me. My browser "does not support the execution of F# code in the browser", probably because I don't have Silverlight. I install Silverlight (for Chrome on OS X). "Could not load Silverlight Plug-In."

  you may have missed it but sites like this have been around for a lot of time, so the similarity and motivation are obviously similar :) TryRuby (which I believe was the first for a non-toy language, and the starter of the try* nomenclature) was put online somewhen in 2005 IIRC.

This seems to depend on Silverlight and so doesn't work on my system. (Actually, I'm just guessing that it needs Silverlight--the page explaining why it doesn't work also doesn't work. Either way, it doesn't work.) You should check out OCaml on the browser[1]. This takes advantage of js_of_ocaml, which is a very good OCaml to JavaScript compiler. You can also try running OCaml with access to the browser apis[2], which is pretty cool.

  The reason the dependency exists is because silverlight includes the .net compiler and, in addition to literally executing the code on the client, is used for a lot of the IDE sugar, like Intellisense. Additionally, you don't just get the f# language here but also access to a lot of the standard .net libraries. So while I agree it's annoying that the dependency exists, it's not an arbitrary requirement to do accomplish something that could have easily been replicated in another technology
  - loeg 14y ago
    Sure, but what makes the whole "in a browser" genre interesting is that (usually) you don't need special dependencies to get started. If I need Silverlight and the whole .NET compiler, why not just tell me to download Visual F# Express Edition to get started?
    - vailripper 14y ago
      Because silverlight takes all of 15 seconds to download and install, and Visual F# is an hour+ to install, plus a couple hundred megabytes of additional assets?

        Complexity. Target achieved.

That's a very interesting learning resource. I wish something similar came for Scala or Clojure (as opposed to tryclj, which does not have all those "Learn" pages).

  What I found very useful was http://4clojure.org http://4clojure.org . The elementary-level and easy-level problems provide a good start.

  Here's a monstrous list of online sandboxed REPLs, i think the first group, codepad, IDEone, etc can do scala and clojure but probably you'll want to go with one of the one click donwloads like Haskell platform, the typesafe installer or leiningen, unless they've somehow developed a miraculous classpath hell resolver. http://jkirchartz.com/2012/06/rocking-stackoverflow-sites-to.html http://jkirchartz.com/2012/06/rocking-stackoverflow-sites-to... http://joel.franusic.com/Online-REPs-and-REPLs http://joel.franusic.com/Online-REPs-and-REPLs

I'm interested in learning F# but can't get past the "Your system does not support the execution of F# code in the browser." Any other pretty painless way to try it? I've been messing with Haskell and like it a lot but it would be nice to have access to the .NET libraries when I wanted them.

  You can run it in mono (it's part of the standard package now) or you can give it a go on tryfs.net once the load goes down. If you're on windows, there's an addon for VS2012 Express Web Edition for F#: http://blogs.msdn.com/b/fsharpteam/archive/2012/09/12/announcing-the-release-of-f-tools-for-visual-studio-express-2012-for-web.aspx http://blogs.msdn.com/b/fsharpteam/archive/2012/09/12/announ...

    Chrome on Debian user here, that link actually provided a link to a moonlight installer for chrome (crx file), however chrome no longer allows downloaded extensions to be installed. Just tried firefox (called Iceweasel in Debian), and moonlight installed ok, but I got this message: // Due to differences between Silverlight and Moonlight, the Linux version of the // Try F# control is not fully functional at this time. // // We will make the Try F# control available on this page as soon as all issues // are resolved. Please check back later and thank you for your understanding. //

      That is a shame. Thanks for putting the effort in.

Also cool, all of the samples on http://fssnip.net http://fssnip.net can be loaded into tryfsharp.org and tryfs.net with the click of a button.

F# really does look like an amazing language. I'll consider it seriously when someone ports it to the JVM.
