Description

This assumes we implement the feature using JSON ZObject encoding urls. Some requirements are up for discussion still in the WIP meetings!

Implement the frontend functionality to generate a shareable link to a function call that encodes the entire call as a URL-encoded JSON ZObject (Z7). This allows contributors to share, reproduce, and debug function calls easily.

When someone opens such a link, the frontend should parse the JSON ZObject, prefill the arguments, and (if configured) automatically run the function.

Requirements

1. Add a "Share" button in:
   • Special:RunFunction , ... TBD by design
2. Clicking “Share” should:
   • Create a JSON ZObject representing the current function call (type Z7), including:
     • Z7K1 – target function ID
     • Z7K2, Z7K3, … – argument values
   • URL-encode this JSON and append it as a query parameter (e.g. ?call=%7B...%7D).
   • Copy the full URL to clipboard and display a “Link copied!” message.
3. On page load:
   • Detect the call= parameter. (name up for discussion)
   • Parse the JSON into a ZObject and prefill the function call interface.

Implementation Notes

• JSON ZObject approach replaces plaintext or mixed encoding approaches.
• Considers URL length limits — this approach is designed for longer and more complex function calls. We do nothing about this.
• Must handle invalid JSON gracefully (show error message, don’t crash).

Acceptance Criteria

• “Share” button present on supported pages.
• Generated URL contains a valid Z7 JSON ZObject of the function call.
• Opening the link pre-fills all arguments.
• (Optional) Function auto-runs if configured.
• Robust error handling and accessibility requirements met.
