what else do we need for javascript extension

[supervoidcoder]

it doesn't work for whatever reason #159 but anyways uh um um uh uh uhm um uh uh uh uh uh uh

uh oh yeah
so like
i noticed when in penguinmod, the blocks have like a little mini code editor with syntax highlighting and line coutner.

in the few hours i got it to partially work I only got regular block inputs

👋 Hi @supervoidcoder! I've detected potential duplicate issues:

• when javascript extension #85: when javascript extension

Please check if any of these existing issues describe the same problem. If so, feel free to add your comments there instead! 🙂

Hi @supervoidcoder! Thank you for sharing this issue.

It seems you're trying to implement a JavaScript extension with additional features similar to the mini code editors in PenguinMod, like syntax highlighting and line counters. From what you've mentioned, the work you've done so far only allows basic block inputs to function. This might indicate missing components or incomplete integration between the editor features and the OmniBlocks environment. It could also be worth examining #159, as you referenced it, for any unresolved issues that might be contributing to this.

If you could provide some additional details or outline what you've already tried, it would be easier to pinpoint where the issue lies. Let me know how else I can assist—happy to help!

@supervoidcoder, I'm here to help! 👋

What would you like me to assist you with regarding the JavaScript extension? I can help with:

1. Investigating the current implementation - I can examine the codebase to understand why the JavaScript extension isn't working (issue Extensions #159)

2. Understanding PenguinMod's code editor blocks - I can look into how PenguinMod implements the mini code editor with syntax highlighting and line counter, so we can replicate it in OmniBlocks

3. Comparing implementations - I can compare what OmniBlocks currently has versus what PenguinMod has for the JavaScript extension

4. Specific file analysis - If you have particular files you want me to examine or help with, let me know!

Just let me know what you'd like me to focus on, and I'll dive into the codebase to help you get the JavaScript extension working properly with those fancy code editor blocks! 🚀

Learning: PenguinMod’s current JavaScript extension folder is src/extensions/jg_javascript with getInfo().id = 'jgJavascript' (camelCase). OmniBlocks should register it with mapping key 'jgJavascript' pointing to '../extensions/jg_javascript' and use extensionId 'jgJavascript' in the GUI.

no @github-actions it's the same extension as the penguinmod one i just copied the extension js but it's not workingg (also don't worry both our proejcts are gplv3)

[github-actions]

Hi @supervoidcoder! It sounds like you're trying to reuse PenguinMod's JavaScript extension, but it's not functioning as expected in OmniBlocks despite being GPL-compatible. Since you've copied the extension code directly, some integration steps may be missing—such as properly registering it in OmniBlocks' extension manager or connecting it to the GUI with the correct IDs.

Additionally, if the mini code editor features like syntax highlighting and line counters aren't appearing, it may be worth verifying if OmniBlocks has the required dependencies or modules set up to support these advanced features. Let me know if you need help reviewing your integration or troubleshooting specific areas!

[supervoidcoder]

@coderabbitai #159 isn't an issue it's a pr but yeah thats the one im trying to impement it in that's the feature pr but it's still a draft for obivous reasons
but yeah could you snoop around in pmods code

also @github-actions do you not realize that both being the same license doesn't fix the issue or have LITERALLY ANYTHING TO DO with the functionality... -_-

[github-actions]

Hi @supervoidcoder! Thanks for clarifying. I understand you're integrating PenguinMod's JavaScript extension into OmniBlocks using the code from its original repository, but it's not behaving as intended. Since both projects share the same GPLv3 license, the compatibility is fine, but as you said, licensing definitely doesn't impact functionality.

From your description, it seems likely there are unresolved integration steps, such as configuring the extension manager, correctly registering IDs, or ensuring required features like syntax highlighting and line counters have functional dependencies within OmniBlocks. I'd recommend closely examining how PenguinMod wires its JavaScript extension into its extension manager and GUI—particularly looking into unique settings or additional files and modules that enable its mini code editor features.

Feel free to let me know which areas you'd like more help investigating or if you'd like some assistance reviewing your current implementation steps. We’ll get this extension working smoothly! 🚀

@supervoidcoder Got it — I snooped around the repo and what’s happening lines up with your experience: the PMod JS extension is loading as a regular text input because the GUI doesn’t have the code-editor field type or editor library wired up.

Here’s what I found and what’s missing

• PR Extensions #159 adds the JavaScript entry to the extension library (extension-library.jsx, index.jsx) and an icon, but there’s no registration for a custom Blockly field or any code editor library:

  • No CodeMirror/Monaco/Ace in the tree.
  • No custom field registration (no FieldCode/FieldMonaco, no Blockly.fieldRegistry usage).
  • Result: Scratch/Blockly renders plain STRING inputs.

• The repo has TurboWarp-style hooks (e.g., src/components/tw-custom-extension-modal, src/lib/tw-extension-gui-api.js), and a userscript that only auto-loads music/pen/text2speech/translate. Nothing currently loads 'jgJavascript'.

• Learned context used: PMod’s JS extension lives at src/extensions/jg_javascript with getInfo().id = 'jgJavascript' (camelCase). OmniBlocks’ GUI should refer to 'jgJavascript'.

What you need to get the mini code editor working like PMod

1. Load the JS extension by the correct ID

• In the GUI library entry, make sure the extensionId is exactly 'jgJavascript' (matching getInfo().id).
• If you want it auto-loaded for testing, update src/addons/addons/load-extensions/userscript.js to include 'jgJavascript' in EXTENSIONS and call vm.extensionManager.loadExtensionIdSync('jgJavascript') (only as a dev aid).
• If you plan to load it externally via TurboWarp’s modal, that’s fine too; just keep the IDs consistent.

2. Add the custom Blockly field used by PMod for code editing

• PMod’s extension renders a code editor via a custom Blockly field (often named FieldCode/FieldMonaco or similar). OmniBlocks currently doesn’t register such a field, so you only see default text inputs.

Implement a small shim to register the field in the GUI bootstrap:

• Create a field module (e.g., src/lib/blockly/field-code.js) that wraps your editor (Monaco/Ace/CodeMirror) and conforms to Blockly’s Field API (show editor, setValue, getValue, serialization).
• Register it before the workspace is injected:

Example (skeleton) to register a custom field

// src/lib/blockly/register-custom-fields.js
import * as Blockly from 'blockly/core';
// If you bring in monaco/ace/codemirror, import or lazy-load it here.

class FieldCode extends Blockly.Field {
  static fromJson(options) {
    return new FieldCode(options.text || '', options);
  }

  showEditor_() {
    // Lazy-load editor assets if needed, then open inline popup or widget div
    // Hook onChange to this.setValue(newValue);
  }

  // Optional: size, render, CSS classes, etc.
}

Blockly.fieldRegistry.register('field_code', FieldCode);

• Import this early in your GUI init (where blockly is set up), e.g., in the module that sets up blocks/workspace (TurboWarp GUI typically has a blockly bootstrap file). Ensure it runs before the editor opens a project.

3. Include and lazy-load the editor library

• PMod uses a real editor for syntax highlighting + line numbers (Monaco or Ace or CodeMirror in different forks). You need to bundle one of these or load it from a CDN at runtime.
• Easiest path: lazy-load on first open to avoid increasing initial bundle size.
• Add minimal CSS so the field’s popup is the desired size. Example: 400x300 inline widget, mono font, gutter for line numbers.

4. Wire the field into the PMod blocks

• PMod’s jg_javascript extension refers to the custom field in its block definition. If PMod emits JSON that names the field type (e.g., "field_code"), it’ll work once the field is registered.
• If it uses a plain STRING arg in getInfo(), PMod likely patches the generated scratch-blocks block to swap a string field for the custom field at runtime. Keep that logic or add a tiny transform when the extension loads.

5. Styling, focus, and platform quirks

• Add CSS to ensure the widget doesn’t overlap the toolbox or flyout and closes on blur/ESC.
• Respect theme fonts and color for a consistent look.
• Ensure the field serializes reliably to project JSON (this.setValue/getValue returning plain text so save/load works even without the editor library).

6. Sanity check the extension ID mapping end-to-end

• The GUI’s extension card should point to 'jgJavascript'.
• vm.extensionManager must be able to resolve that ID:
  • If your VM build doesn’t embed jg_javascript, either backport PMod’s extension into your VM or use TurboWarp’s custom-extension URL path (the modal you already have).
  • For dev, temporarily auto-load it (see step 1).

Concrete touch points in your repo

• Add + register field: create e.g., src/lib/blockly/register-custom-fields.js, import it wherever blockly is initialized.
• Editor assets: add monaco/ace/codemirror (lazy module or CDN) and load it inside FieldCode.showEditor_().
• Extension auto-load (optional, for dev): src/addons/addons/load-extensions/userscript.js → add 'jgJavascript' to EXTENSIONS.
• Library entry: verify 'jgJavascript' in src/lib/libraries/extensions/index.jsx and the gallery icon you added.

Why you’re only seeing plain inputs right now

• Without a custom Blockly field and editor library present, the block argument renders as a normal text field. PMod’s code editor UX comes from their patched scratch-blocks + the custom field class + editor assets. OmniBlocks doesn’t have those yet.

If you want, I can help you:

• add the field scaffolding,
• pick an editor (Monaco or CodeMirror) and wire a lazy loader,
• and sketch the import spot so it’s only included once during GUI init.

Also, let me know if you prefer embedding the extension into your VM build vs. loading it externally through the modal. I’ll tailor the steps accordingly.

Notes

• I used the earlier PMod learnings about the extension folder and ID so we don’t mismatch IDs in the GUI.
• I didn’t assume a specific editor library from PMod’s current build; if you want me to match theirs exactly, I can dig into their repo and mirror it one-to-one.

@coderabbitai actually i was wrong, pmod and me both use the sp_javascriptV2 extension.
