Features

XML Views Auto-Complete/Context-Assist

For example: • Auto-insertion of name for closing tags for classes and aggregations. • Auto-insertion of ="" for attribute key suggestions. • Auto-insertion of the xmlns prefix for classes and aggregation tags. • Tooltips displayed while browsing the suggestions including a clickable link to the SAPUI5 SDK (Demo Kit).

Description

The list of validations and their severity are currently hard-coded and cannot be configured by the end user.

Validation List

• Errors: • Invalid boolean values • Unknown attribute keys • Unknown eum values • Unknown xmlns namespace • Unknown tag names • Duplicate ID tags • Wrong cardinality of aggregation • Wrong type of tags inside aggregations • Missing or empty ID when flexEnabled is true in manifest.json (stableID) • Property binding info or aggregation binding info • missing key • missing or extra colon(s) • missing or wrong value • missing or extra comma(s) • duplicate keys • unknown key or char(s) • recursive composite bindings (only property binding info) • Warnings: • Use of deprecated classes • Use of deprecated aggregations • Use of deprecated properties • Use of deprecated events • Use of deprecated associations • References to annotations that cannot be found in current project • References to filter bars that cannot be found in current file • Use of context paths that do not lead to the annotations of types expected for the given building block

Relevant User/Workspace

• UI5LanguageAssistant.LimitUniqueIdDiagnostics is set off by default to check all *.fragment.xml and *.view.xml files for unique IDs. If you like to limit this validation to the current file, set it on.

XML View Quick Fix

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.

When working with CAP projects, make sure you have @sap/cds module installed. For this, run npm install on your project. This command will download and install all necessary modules from the npm package repository.

Enabling offline work

You can set up a local web server to host one or more supported versions of SAPUI5 SDK and register it in the user/workspace setting "UI5LanguageAssistant.SAPUI5WebServer". This overrides the public CDN of SAPUI5 SDK in the extension and enables offline work with the apps having the matching hosted "minUI5Version" in manifest.json. When configuring local web server, make sure it responds to the exact UI5 version defined in manifest.json e.g /1.111.0…
