  • Default content types and schema associations are defined for the most common web editor related JSON files (e.g. package.json, .eslintrc).

Upgraded all language servers

Edition assistance should be improved on many aspects, and several bugs now fixed.

Refactored ESLint support

ESLint support is now a standalone language server, which doesn't require TypeScript, tsconfig nor anything else tan plain ESLint configuration files to work. The support now use the same language server has the VSCode ESLint extension, which delegates to the ESLint command available in customer's node_modules folder.

Trimmed embedded node_modules

Less node_modules are embedded, this should result in a reduced disk footprint.

Enable upgrade of "web" components without upgrading XML support

This allows to more easily installed Wild Web Developer beside potentially conflicting/restratining 3rd party features and plugins.

0.11.3

Upgraded YAML language server

Adds support for some new yaml features.

0.11.2

Upgraded Angular and YAML language servers

This fixes a few bugs, and improves support for some new yaml features.

which includes...

Support for TypeScript 3.9

Upgrade of typescript and tsserver bring 3.9 support out of the box

0.11.0

Embedded Node.js

Node.js is now embedded into Wild Web Developer. Unless the "org.eclipse.wildwebdeveloper.nodeJSLocation" system property is set and developer's system suits the supported OSs (Linux, MacOS and Win32) and architectures (x86_64), the embedded version of Node.js will be used by Language Servers and Node Debugger.

By adding the org.eclipse.wildwebdeveloper.embedder.node.feature into the dependencies, developers might use the Node.js Embedder's NodeJSManager class in order to automatic install/use of the embedded version of Node.js in their products.

TypeScript program debug support

TypeScript programs can now be directly debugged using Node program Debug Configuration.

TypeScript 3.8 demo

XML Catalogs preference page

You can now define XML catalogs via preference page.

Language Servers update

Most language servers got updated to their latest version, bringing new features and bugfixes.

⚠️ Breaking extensions ⚠️ Move to LemMinX 0.12.0

LemMinX XML language server was upgraded to 0.12.0, with a lot of improvements. However, please note that the extension API has changed in a non-backward compatible way; so to work with newer Wild Web Developer, ensure the extensions to org.eclipse.wildwebdeveloper.xml.lemminx are compatible with LemMinX 0.12.0.

0.10.0

Extension point to define initializationOptions to LemMinX XML Language Server

The extension point org.eclipse.wildwebdeveloper.xml now allows a new initializationOptionsProvider child element type, which can be used to specify some initialize options. This is typically useful for language server who should be configured according some some user preferences already configured somewhere else in the IDE, so such preferences can be propageted to the language server.

Extension point to define JSON Schema URLs

The extension point org.eclipse.wildwebdeveloper.json.schema allows record JSON schema for filename pattern. This records are registered in JSON Language Server during initialization:

<extension point="org.eclipse.wildwebdeveloper.json.schema">
      <schema pattern="composer.json" url="http://json.schemastore.org/composer" />
</extension>

0.9.1

Support for Node.js 14

Wild Web Developer was successfully tested against node.js 14, so it's been added to the list of compatible versions, and no warning pop-up will show for users of Node.js 14.

Install XML support separately

A feature containing XML editor was extracted and can be installed separately, without installing all other Web tools (HTML, JS and so on).

0.9.0

Breaking changes

  • Extension point org.eclipse.wildwebdeveloper.lemminxExtension now replaces org.eclipse.wildwebdeveloper.xmllsExtension
  • Interface LemminxClasspathExtensionProvider now replaces XMLLSClasspathExtensionProvider
  • XML Language server is now Eclipse Lemminx 0.11.0. Extensions must be built targetting this language server (package name have changed)

Select Chrome/Chromium instance in Debug configurations

When debugging against Chrome/Chromium, the related Debug Configurations now shows an extra tab that allow to select the browser instance to use. This is convenient when user has multiple instances of Chrome/Chromium installed and want to test against multiple ones. The default behavior didn't change and will look for a relevant instance in the PATH.

0.8.3

TypeScript 3.8 support

Wild Web Developer supports the latest release of TypeScript, 3.8

0.8.1

📅 Release Date: January 20th, 2020

Proxy honored for XML resolution

The proxy settings are now used by the XML edition assistance (eg to resolve XSD elements). The network settings of Eclipse IDE are used, and if the network settings are blank, the related System Properties of the running/host Eclipse process itself are forwarded to XML resolution. This fixes issue #192.

ESLint and Typescript-ESLint support

ESLint is now supported in Wild Web Developer, providing both code diagnostics and quick fixes (when available) for JavaScript and Typescript files.

To enable ESLint for a project, a .eslintrc, tsconfig.json as well as the required node_modules must reside within the project's directory (or in a parent directory). The required node_modules can be installed with npm install eslint@6.0.0 @typescript-eslint/eslint-plugin@2.7.0 @typescript-eslint/parser@2.7.0 typescript@3.6.4.

An example .eslintrc can be found here and a example tsconfig.json can be found here

For more information on configuring ESLint, visit https://eslint.org/docs/user-guide/configuring.

Improved XML language server extensibility

Extension point to add jars to XML Language Server has been augmented to allow passing a dynamic resolution of multiple jars.

0.8.0

📅 Release Date: 19th November, 2019

XML language server extension support

XML-LS extension jars can now be integrated into Wild Web Developer through the xmllsExtension extension point, allowing additional functionality to be provided from the language server.

The extension jars must implement the IXMLExtension interface and must register with Java Service Provider Interface (SPI) mechanism in the /META-INF/services/org.eclipse.lsp4xml.services.extensions.IXMLExtension file. To use the extension point, create an xmllsExtension extension in a plug-in project and set the path to the location of the extension jar (which must reside within the plug-in project).

Usage example:

    <extension
          point="org.eclipse.wildwebdeveloper.xml.xmllsExtension">
       <jar
             path="path/to/extension.jar">
