• Fix typo in program initializer agrument.

Formatter

• Add separator to locale formatter.

Bundling

• Make sure public files are available when using --hash-routing in reactor.
• Use main.js file for initialization.

Type Checker

0.27.0

Language

• Removed syntaxes which were deprecated in 0.20.0 (to migrate automatically run mint format with any binary between 0.20.0 and 0.26.0):

  • Constant access using colon :
  • Type variants using double colon ::
  • enum, record keywords
  • HTML expressions <{ }>

• Added context feature to pass down props without prop drilling. (#783)

• Allow testing and unboxing on Maybe, Result and Html in if.

• Allow record destructuring in statements.

LSP

Housekeeping

• Update dependencies (#788, #784, #785)

0.26.0

Standard Library

• Added arguments for upload and download progress to Http.send.
• Added FormData variant to Http.ResponseBody.
• Added FormData.getFile and FormData.getString functions.
• Added File.fromUrl function.
• Added Regexp.exec function.
• Added Html.DataTransfer.getMimeTypes function.

Exporting Entities

The build command now takes any number of --export arguments which allows exporting entities from the final bundle.

Functions and constants can be exported from modules, variant constructors from types and components. Components are exported in a way that they can be used easily.

Here is a minimal example:

component Greeter {
  property name : String = ""

  fun render {
    "Hello #{name}!"
  }
}

mint build --export Greeter

import { Greeter } from `index.js`;

// Render the component into a DOM element.
Main.render(document.querySelector('div'), { name: "Joe" })

Bugfixes

• Properly resolve static type signature of Ast::Type
• Make sure that variable labels survive pruning. (#780)

0.25.0

CLI

• Add command line switch to display browser output during mint test. (#770 @MathiusD)
• Add more information for the lint command with the --json flag. (#465)
• Show warning for port mismatch when running tests. (#684)

Language Server

• Implement textDocument/documentSymbol request for the language server. (#647)
