0.17.0

🚧 !!! This is a big release containing many breaking changes !!! 🚧

---

This release got pretty big and it would take a long time to gather all the changes, apologies for that.

Breaking Language Changes (check PRs for detailed changes)

• #503
  • Allow multiple statements per block and added standalone block notation.
  • Promises changed to take a single parameter instead of two Promise(value).
  • Removed try, parallel, sequence, with, where, catch, finally and then language features.
  • Removed partial application language feature (conflicting with default arguments) until we can figure out a solution for the ambiguity.
  • Removed safe operators &. and &(.
  • Added block expressions.
  • Added optional await keyword to statements.
  • Added optional await keyword to the condition of case expressions.
  • Added the ability to define default values for function arguments.
  • Added the ability to create decoder functions using the decode feature by omitting the decodable object: decode as Array(String).
  • Records are now using : instead of =.
  • Added here document support:

    <<#MARKDOWN
    Renders markdown content to Html
    MARKDOWN
    
    <<-TEXT
    Text content which leaves leading indentation intact.
    TEXT

    TEXT
    

• The pipe operator |> now puts the left hand side value as the first argument instead of the last. #571

Standard Library

Language Server

• Fix 100% CPU in Language Server when receiving EOF from STDIN #573 @jansul

Housekeeping

0.16.1

Make sure the build command succeeds if the public/assets folder is present.

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

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

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

• Eliminate versions of packages with missing or invalid mint.json when installing dependencies.

Compiler

• #467 #115 Don't minimize the CSS classes in development.

  

  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.
• Fixes documentation comments for some functions.

Housekeeping

• More cleanups and refactors - @Sija
• 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
    => ""
  }
