  • v0.8.0

    March 13, 2020

    This release contains 122 commits from 6 contributors 🎉

    🍱 🚧 Breaking changes 🚧

    Mint now uses Preact instead of React (this should not break anything though) which will result in smaller compile files.

    🍱 External assets are now handled differently:

    • stylesheets are now supported as well
    • javascripts and stylesheets are now compiled into their own file

    - more information in issues and PRs: #151 #155 #183

    CSS rules whith multiple selectors are now compiled separately f2eab4b:

    div,p { color: red; }
    

    now compiles as:

    div { color: red; }p { color: red; }

  • v0.7.0

    December 09, 2019

    Global components

    🛠 Components can be prefixed with the global keyword, this will add them to the DOM automatically and it's methods can be called the same way as a store or module.

    It is useful for components that only need one instance in the application,
    like modals and notifications:

    global component AlertModal {
      state shown : Bool = false
    
      fun open : Promise(Never, Void) {
        next { shown = true }
      }
    
      fun close : Promise(Never, Void) {
        next { shown = flase }
      }
    
      style base {
        position: fixed;
        bottom: 0;
        right: 0;
        left: 0;
        top: 0;
      }
    
      fun render : Html {
        if (shown) {
          <div::base> 
            <p>
              Are you sure?
            </p>
    
            <button onClick={close}>
              Ok
            </button>
          </div>
        } else {
          <></>
        }
      }
    }
    
    /* Later on somewhere else */
    AlertModal.open()
    

    Statically compiled components / HTML

    🚀 In this release the compiler will detect components and HTML fragments that are essentially static, meaning that subsequent renders would always result in the same virtual DOM structure.

    These fragments and components will be cached so to speak, they will only rendered once and get reused after that.

    To give you an example, the following component will only be rendered once and is reused after that:

    component Icons.Checkmark {
      fun render : Html {
        <svg>
          /* The svg data */
        </svg>
      }
    }
    
    component Main {
      fun render : Html {
        <div>
          <Icons.Checkmark/>
          <Icons.Checkmark/>
        </div>
      }
    }

    💥 Breaking Changes

    • References of elements and components now return a Maybe

    Implemented safe operators (&. and &() for dealing with Maybe in specific cases:

    JavaScript output optimizations

    ⚡️ All generated JavaScript code is now optimized in the following way:

    • top level entity names are now mangled (Components, Stores, Modules, etc.)
    • entity level names are now mangled
    • 🏗 white space is removed from the generated code (build only)
    • the CSS selectors and variables are now mangled

    This change means that inlined JavaScripts no longer can access arguments by name.

    This will result in a runtime error because the argument message is mangled:

    fun log (message : String) : Void {
      `console.log(message)`
    }
    

    To fix this we need to interpolate the argument:

    fun log (message : String) : Void {
      `console.log(#{message})`
    }
    

    Calls on expressions

    Previously the calls to functions were implemented in two forms: call on a
    variable and call on a module function.

    This meant that calling a function which
    is in a record or which is a result of a function call were not possible.

    🚀 This release makes it possible to make a call on the result of an expression.

    This is an example which raises in error in 0.4.0 but compiles properly in 0.5.0:

    module Test {
      fun a (message : String) : Function(String) {
        () : String => { message }
      }
    
      fun b : String {
        a("Hello")()
      }
    
      fun c : String {
        try {
          record = {
            function = (message : String) : String => { message }
          }
    
          record.message("Hello")
        }
      }
    }
    

    Partial Application

    Functions now can be partially applied by calling them with less arguments than
    needed.

    An example of using partial application:

      /* Format a number by thousands, output: 1,000,000 */
    
      "1000000"
      |> String.split("")
      |> Array.groupsOfFromEnd(3)
      |> Array.map(String.join(""))
      |> String.join(",")
    
      /* 
        The argument String.join("") (to Array.map) is a partially applied function
        where it's type is Function(Array(String), String)
      */
    

    ⚠ Warning for unkown CSS properties

    CSS properties are now checked against a list and will result in an error if
    they are not in the list.

    🔄 Changes

    • 🛠 Fixed array access ([]) when an expression is used as an index
    • 0️⃣ Default values of properties are now only calucated once when the component is initialized
    • Providers can now be accessed the same a stores, or modules for introspection
    • Records now can be created without type definition. Such records have a temporary type definition created for them during type checking
    • [Runtime] Functions are bound to components and modules only once (in the constructor) instead of using .bind every time they are called

    Formatter

    • Inline functions can now be forced to format the body on a new line by adding
      a line break after the opening bracket {
    • 0️⃣ Properties can now be forced to format the default values on a new line by
      ➕ adding a line break after the equal sign =
    • ➕ Added missing formatter for array access ([])

    Core

    • ➕ Added Array.groupsOfFromEnd which is the same as Array.groupsOf but grouping from the end
    • ➕ Added Array.indexBy to get an items index by a function
    • ➕ Added Http.requests for inspection purposes
    • ➕ Added String.rchop
    • ➕ Added String.lchop
    • Html.Event is now wrapped in an actual record, so it can now be safely used in sequence or parallell expression
