0.16.0

Parser

The parser has been speeded up thanks to @asterite (#537) - it should parse twice as fast and consume half the memory in the general case.

Type Checker

• Fixed a bug in scoping #529

Bundler

• The service worker now only falls back to paths that matches any routes defined for the application @Eternahl #370 #539

Language Server

• Added FoldingRange provider.
• Added CodeAction provider.
• Added a code action to sort the module entities in order.

Standard Library

• Added Math.trunc
• Added String.padLeft
• Added String.takeRight

Time module rewrite

The time module has been completely reworked, check the PR: #526 and the docs for more information.

Housekeeping (@Sija @gdotdesign)

• Bumped Crystal version requirement to 1.3.2
• Makefile: Build the binary only if there are changed files
• Updated dependencies

0.15.3

Fixed runtime error in Clipboard.set

0.15.2

• Fixed a bug in function scoping #529
• Fixed a bug in runtime which broke it on Safari

0.15.1

Fixed a regression in inline styles handling, where using an non-string attribute could lead to runtime errors (mint-lang/mint-runtime#24)

0.15.0

Language

• Time is now automatically serialized into String #357
• Tuples now can be automatically serialized #519
• Fixed selector reference & in styles #479
• or operator can be used with Result(error, value) as well

LSP

• Added basic completions for HTML tags and CSS properties #511
• Added completions for enum options #518
• Fixed cursor position lookup #481
• Fixed some compatibility issues with specific clients #493
• Honor snippetSupport client setting #520

CLI

• A custom runtime can be used with the --runtime flag for the build and compile commands #476

Service Worker

• Fix service-worker generation issue #506

Standard Library

• Clipboard.set now returns a string and restores focus and text selection #524
• Added Time.fromUnixTimestampInMs and Time.toUnixTimestampInMs #522

Web Components

• Components can now be exported as web components #501

  A new field was added to the mint.json for this purpose:

  {
    "name": "my-library",
    "web-components": {
      "Button": "my-button"
    },
    "source-directories": [
      "source"
    ]
  }

  In the object, the key of the field refers to the component and the value refers to the tag name of the web component, in this case, the Button component will be exported as <my-button>.

Housekeeping

• More cleanups and refactors by @Sija

0.14.0

Documentation Generator

• Fix documentation generation for modules.

Installer

  Don't use these CSS classes for targeting - either with DOM or as sub styles - because they are minimized in production!

• Update the list of valid CSS property names - @Sija

• Fixes in the generated service worker.

Standard Library

• BREAKING CHANGE Renamed treshold field to threshold in the subscription for Provider.Intersection.

• Update documentation viewer app.

0.13.1

0.13.0

Breaking Changes

• Enum destructuring within case statements now uses parentheses and commas instead of whitespaces.

  Given this enum:

  enum Status {
    LoggedIn(Time, User)
    LoggedOut
  }

  Destructuing before:

  case (maybe) {
    Status::LoggedIn time user => true
    Status::LoggedOut => flase
  }

  After:

  case (maybe) {
    Status::LoggedIn(time, user) => true
    Status::LoggedOut => flase
  }

  This was a necessary step to make nested destructuring work.

Language

• #81 #451 Added line comments: 🎉

  // Line comment
  fun render : Html {
    ...
  }

• Added @inline directive which inlines a text file into Mint code as String:

  @inline(path/to/file.html) /* String */

• #418 #419 Added index variable to the for loops:

  /* Iterating over Array(item) or Set(item). */
  for (item, index of array) {
    ...
  }
  
  /* Iterating over Map(key, value). */
  for (key, value, index of map) {
    ...
  }

• #437 Tuples can be destructured recursively (@matthewmcgarvey):

  case ({"A", {"B", "C"}}) {
    {a, {b, c}} => c
    => ""
  }

0.12.0

This release brings language server support and asset handling to Mint!

Language Server 🎉

One of the highly requested features the language server is now available using the mint ls command.

Having this shipped allows us to incrementally implement other features such as showing errors and goto declaration / implementation.

Format on save

The files are formatted when saved if they don't contain any errors.

Hover Provider

The type information of most entities can be checked by hovering over them also, if available the documentation is displayed as well.

Completion

Completions are provided for entities in stores, components, modules and also in scope variables (depending on where to cursor is).

New App Template

A new application template has been implemented!

Language Features

The asset directive was implemented also support for constants in tests.

Asset Directive

The asset directive allows you to reference an asset (image, stylesheet, video, etc..) - relative to the current file. These assets are bundled in the production build.

component Main {
  fun render : Html {
    /* The image should be in the same directory as this file. */
    <img src={@asset(some-image.jpg)}/>
  }
}

Only those assets get bundled which are touched during type checking, for example if a component references some assets then those assets are only bundled if that component is used.

Constants in Tests

Constants can now be used in tests:

suite "Some tests" {
  const VALUE = "Hello"

  test "Constant equals Hello" {
    VALUE == "Hello"
  }
}

Runtime

• Fixed Preact to 10.4.4 (last known working version).
• Don't use shouldComponentUpdate in components #316.
• Normalize dataTransfer and clipboardData fields in events.
• Properly resolve page position after navigation (hash jump, scroll to top).
• Don't handle links that point out of the current frame.

Formatter

• Implemented missing CSS keyframes formatter.
• Properly format Html body when there are only comments inside.
• Open modules now format properly (not duplicating entities).
• Format Html body properly if it's children has new lines.
• Format inline functions as multiline if they contain new lines.
• Format state statements as multiline if appropriate.

Housekeeping

• Crystal 1.0 compatibility.
• Builds now use the latest crystal version.
• #375 Contribution guide has been updated (@itsgreggreg).
• #383 Github actions has been improved (@Sija).

Standard Library

• Added Map.fromArray.
• Added String.wrap.
• Added String.indent.
• Added String.indentWithOptions.
• Added Time.nextWeek.
• Added Time.previousWeek.
• Added Function.debounce1.
• Added Html.Portals.Head component.
• String.parameterize now converts titlecase to dash case.
• Window.isActiveURL now ignores search (query) parameters and the hash.
• Window.open now works again #390.
• Make sure the copy clipboard function does not scroll the page.

Minor changes / fixes

• Use Array(Char) instead of String in the parser which speeds up parsing in some cases.
• #385 Rename manifest.json to manifest.webmanifest (@jonathanoberg).

Fixed issues

• #371 Case does not unify branches which can lead to unexpected behaviour.
• #372 Make sure that module functions are resolved in the proper scope.
• #373 Convert string literals in CSS values to string unless they contain interpolations.
• #376, #358 Make sure that error messages render properly.
• #381 Try now can return a result directly (@itsgreggreg).
• #366 Gracefully shut down the test runner in case of uncaught exceptions in JavaScript (@Sam647254).

0.11.0

This release focused on bug fixes, although there are some new language features.

Language Features

Regular Expression Literal #250

Mint now supports regular expression literals:

Regexp.match("abbc", /ab+c/i) == true

Open Modules #265

Modules now can be defined in multiple places allowing to define constants and functions.

module Greeter {
  fun greet (name : String) {
    "Hello #{name}!"
  }
}

module Greeter {
  fun greetPolitely (name : String) {
    "Have a nice day Mr. #{name}!"
  }
}

This is mostly useful if you want to extend a module in the standard library (like Array).

Or operator

Added the or operator as an alias to Maybe.withDefault:

Maybe.withDefault("Hello", Maybe::Just("Value")) /* "Value" */
Maybe.withDefault("Hello", Maybe::Nothing)       /* "Hello" */

Maybe::Just("Value") or "Hello" /* "Value" */
Maybe::Nothing or "Hello"       /* "Hello" */

[] access on tuples

It is now possible to use [] on tuples:

{"Name", "Joe"}[0] == "Name"

Only literal numbers are valid since it's the only way we can only determine the type.

Formatter

• Format the type signature of the inline JavaScript if given.
• Format the type signature of an array literal if given.

Housekeeping

• Moved the CI from Travis to Github actions.

Standard Library
