Installation

From the VS Code Marketplace

In the UI5 Language Assistant VS Code marketplace page, click Install.

From GitHub Releases

1. Go to GitHub Releases.
2. Search for the .vsix archive under ui5-language-assist\@x.y.z releases. (Replace x.y.z with the desired version number.)
3. Follow the instructions for installing an extension from a .vsix file in the VSCode's guide.

Usage

This extension's features are automatically enabled when opening/editing relevant SAPUI5 source files. For SAPUI5 XML views, this means:*.view.xml or *.fragment.xml files.

Note that the extension lazily downloads the SAPUI5 metadata needed for its features. This means that there may be a delay between starting VS Code and having the relevant features available.

Limitations

SAPUI5 version

This extension currently uses a hard-coded (1.71.x) version for the SAPUI5 metadata.

Custom controls

This extension does not currently support custom controls, some features, such as validations, may use heuristics to guess that a tag is a custom control. However, no auto-complete is currently offered for custom controls.

Support

You can open issues on GitHub.
