ElixirScript - converts Elixir to JavaScript

bryanjos

Hi, I just published version 0.23.0 of Elixirscript.

https://github.com/bryanjos/elixirscript/blob/master/CHANGELOG.md

Most of the changes are around JavaScript interop now that Elixirscript uses the Elixir compiler to compile and load files during compilation. This also means you can define macros in the same file now. Another bonus is that this release makes it a bit easier to share code between Elixir and Elixirscript.

That’s about it. Try it out and any feedback is always helpful.

I’ve been tempted to write a little webcomponent or polymer or so integration with it to see how it works, be a nice little bite-size thing to test with.

Hello I just published the latest version of Elixirscript. For a full list of the changes, take a look at the changelog The major changes in this version are:

Can select between ES, CommonJS, or UMD module formats for output
Can use and compile dependencies in mix projects (if dependency has the elixirscript compiler in its mix compilers)
Default input and output paths in mix projects

There is now an elixirscript organization with the projects that it uses. Also there is a newly created blog with the first post giving more details about the majors changes.

Finally, a gitter room was created for the project. The elixirscript channel on the elixir-lang slack still exists and I’ll still be there. The gitter room allows for integrations and keeps the history.

Just published version 0.27.0 of elixirscript. One major change is that super and defoverridable are now implemented. The other is that JavaScript functions, properties, and modules can now be accessed from the JS module, examples: JS.alert("hi"), JS.console.log("hi"), JS.Date.now()

For the rest of the changes, please check the changelog

No new release just yet, but thought I’d send an update.

Thanks to the changes in OTP 20 and Elixir 1.5, ElixirScript was rewritten and can now support almost all Elixir features besides receive. More information is in this blog post.

Another addition is a change in JavaScript interoperability with an FFI module. More information on that can be found here

Next I’ve update the Todo Example to work with ElixirScript in master. I have taken the react parts in made it into a library that it uses. Showing how an ElixirScript library could look. Basically a normal mix project with javascript files in the priv folder if neeeded.

Most of the work now is implementing whatever Erlang calls Elixir makes in JavaScript. That’s where contributions to the project are definitely the most helpful. The other is in fixing bugs that appear along the way.

For a release, hoping to have something before ElixirConf.

P.S: receive

Want to support this eventually. I would like to be able to implement a process system in JavaScript using async/await and use that in ElixirScript, but my brain can’t quite grasp how to do so. Any help there would be appreciated

Edit: Or using the current implementation that uses generators is a possibility, but async functions seem to play better with normal javascript functions.

Hmmm… maybe you would like using OCaml syntax instead of ReasonML syntax (both compiled to JS by Bucklescript) if you want a less verbose syntax. Although in that case not sure how you can use JSX. There is the bucklescript-tea project but instead of JSX it uses an Elm-style list-of-list representation of the DOM.

Maybe someone knowledgable over on the ReasonML Forums would know how you could use ReasonReact and JSX (which like you said is just calls to React.createElement) with the less verbose OCaml syntax. It must be possible I’ve just not seen examples.

I’m not as interested in the syntax but the excellent inferred typing (without using TS or Flow) is the big win for me. Biggest drawbacks is having to find (or write) bindings to random 3rd party JS libraries (if you need them) and the relatively small (but friendly) community. Anyway it might be close to what you are looking for.
