elixir_script v0.23.0 Release Notes

Release Date: 2016-11-15 // over 7 years ago

  • ➕ Added

    • 👍 with now supports else
    • Implement context option on quote
    • 🆕 New compiler pipeline
    • @on_js_load. Expects a 0 arity function. This function will be called when the compiled module is loaded in JavaScript
    • 0️⃣ JS.import\3. Just like JS.import\2 but expects options to decide if the import should be a default one or a namespace on. Only option allowed is default. Set to true by default
      # translates to "import A from 'a'"
  JS.import A, "a"

  #translates to "import * as A from 'a'"
  JS.import A, "a", default: false

    ✂ Removed

    • 0️⃣ The form of JS.import that accepted a list of atoms as the first arg. Used JS.import\3 with default: false instead to create a namespace import
    • env and root are no longer options for ElixirScript's compile functions and cli
    • 👍 Syntax once supported by Elixirscript JQuery.("#element"), is no longer supported

    🔄 Changed

    • Changed CHANGELOG.md to adhere the format from Keep a Changelog
    • 👍 defmacro now supported. No longer have to separate macros from functions in separate files. defmacrop still unsupported
    • To use anything in the JS module, you must require the JS module first
    • Elixirscript files must now contain valid Elixir syntax.
    • 👍 Now compiles exjs and ex files within the path can be compiled all the same. Dependencies from hex are still unsupported so these files must not rely on any code outside of the path. What this does mean is that it is now possible to share code between Elixir and Elixirscript as long as the Elixir files functionality fall within what Elixirscript currently supports.
    • defgen, defgenp, yield, yield_to, and object are now in the JS module
    • To access functions in the global JavaScript scope, either use JS.global\0 or use the erlang module call syntax
      #calling alert
  JS.global().alert("hi")

  #calling alert
  :window.alert("hi")

    Calling JavaScript modules in the global scope works without using the above methods

      #calls window.Date.now()
  Date.now()
