Other Useful Enhancements

  • Editor decorations for Hprompt frontmatter and role lines. You can customize their appearance via settings.
  • Foldable & sticky-scroll headings for easier navigation.
  • Snippets for relatively complex Hprompt constructs.
  • Frontmatter YAML validation with real-time feedback. Requires installation of the YAML extension and proper schema configuration (see next section).

Frontmatter Validation Setup

Follow these steps to enable YAML validation for Hprompt frontmatter.

  • Install the Red Hat YAML extension.
  • Configure a schema for *.hprompt.yaml (hprompt frontmatter virtual documents) by adding the following to your settings.json: 
    {
	"yaml.schemas": {
		"https://raw.githubusercontent.com/atomiechen/HandyLLM/main/assets/hprompt-fm.schema.json": "*.hprompt.yaml"
	}
}
    You can also download the schema file and reference it locally if preferred.

Once configured, the frontmatter area supports schema-based hovers and completions while you type.
