Specific XSLT extension settings

Creating User and Workspace Settings

From the Command Palette (⇧⌘P) you can either invoke Preferences: Open User Settings or Preferences: Open Workspace Settings. Editor settings can also be applied in a language-specific way, for this, use the command Preferences: Configure Language Specific Settings.

Settings are either edited in the Settings form opened or in a JSON editor. Open the JSON editor by clicking the Open Settings (JSON) button at the top right of the Editor Group (see screenshot). This opens the corresponding settings.json file directly.

XSLT Extension Specific Settings

Type xslt to show a short-list of settings specific to XSLT:

XSLT Packages

To allow XSLT package names to be resolved to file paths, package details should be added to the setting XSLT.resources.xsltPackages.

Sample XSLT package settings

"XSLT.resources.xsltPackages": [
  { "name": "example.com.package1", 
    "version": "2.0", 
    "path": "included1.xsl"
  },
  { "name": "example.com.package2",
    "version": "2.0", 
    "path": "features/included2.xsl"
  },
]

CODE

XSLT Tasks

The Saxon XSLT-Java and XSLT-JS TaskProviders are enabled by default. These can be enabled or disabled using the following settings properties:

"XSLT.tasks.java.enabled": true
"XSLT.tasks.js.enabled": true

CODE

General Settings For XSLT

You can set your preferences for XSLT and XML editing so they don't affect coding in languages managed by other extensions: this.name

  "[xslt]": {   
    "editor.defaultFormatter": "deltaxml.xslt-xpath",
    "editor.formatOnSaveMode": "modifications",
    "editor.formatOnSave": true,
    "editor.formatOnPaste": true,
    "editor.formatOnType": true,
    "editor.semanticHighlighting.enabled": true,
    "editor.wordSeparators": "`~!@#%^&*()=+[{]}\\|;'\",:<>/?$",
  },
  "[xml]": {
    "editor.defaultFormatter": "deltaxml.xslt-xpath",
    "editor.formatOnSaveMode": "modifications",
    "editor.formatOnSave": false,
    "editor.formatOnPaste": true,
    "editor.formatOnType": true,
    "editor.wordSeparators": "`~!@#%^&*()=+[{]}\\|;'\",:<>/?$",
  },

CODE

Code Formatting

The following settings directly affect code formatting in the XSLT/XPath extension:

    "editor.defaultFormatter": "deltaxml.xslt-xpath",
    "editor.formatOnSaveMode": "modifications",
    "editor.formatOnSave": true,
    "editor.formatOnPaste": true,
    "editor.formatOnType": true,

CODE

The editor.formatOnSaveMode setting can be used to only format XSLT lines changed since the last commit on Git.

Syntax Highlighting

Syntax highlighting for XSLT and XPath is achieved using Visual Studio Code's Semantic Highlighting tokens alone. Almost all other languages in Visual Studio Code use a TextMate Grammar for tokens which may be supplemented by Semantic Highlighting.

To ensure XSLT and XPath is syntax highlighted in any Color Theme, you should explicitly enable Semantic Highlighting with the setting:

"editor.semanticHighlighting.enabled": true

CODE

Word Separators

The editor.wordSeparators setting affects how the full 'word' is selected when you double-click on a part of the word. The characters listed are used as word separators. Typically in XSLT, you do not want characters like - and . treated as word separators as these characters are valid within a QName like an arrtibute name or a variable name.

Emmet Snippets

Emmet Snippets provide a convenient shorthand for inserting a number of literal result elements and attributes into your XSLT in one go. To enable Emmet snippets for XSLT, add the following setting:

"emmet.includeLanguages": {
    "xslt": "xml"
},
