Bladed 5 Tools for Visual Studio Code

The Bladed 5 Tools extension provides input validation, auto-completion, tooltips, and enhanced syntax highlighting making it easier to create Bladed 5 JSON input files using Visual Studio Code.

Activate the extension features

After installing the Bladed 5 Tools extension, make sure your JSON file includes the $schema property at the top of your JSON file, pointing to a valid Bladed JSON schema. This line activates the extension’s features.

For example, this URI points to the root Bladed 5 schema, which is required to validate all inputs used in a simulation:

{
    "$schema": "bladed-schema://5.0.0/simulate/BladedAnalysis.json"
}

Validation

Get real-time validation as you edit. Errors are visible directly in your editor or you can look at them by opening up the Problems panel (Ctrl + Shift + M on Windows).

Auto-complete

When authoring properties, the schema provides auto-complete suggestions to show what Bladed 5 supports. If a default value exists, it will be inserted automatically.

Additionally, auto-complete suggestions can be triggered at any point in the document by pressing Ctrl + Space.

Tooltips

Hover over any field name or object to view contextual details such as its description, required JSON input type, unit, and — where relevant — its default value.

Syntax highlighting

Bladed-specific JSON properties are rendered with custom syntax highlighting, making key fields easy to spot and understand.
