Code Bundle is a tool that packs your project together with additional relevant information into a single json file, that can be provided to AI assistants for debugging, learning, refactoring and other tasks.

The bundle is created with a click of a button (Ctrl + R). The bundle includes:

• Project code + list of public APIs. Keys are sanitized based on heuristic templates.
• (optional) Logs + compilation output + warnings and errors list. Compilation output is included when the dialog is visible.
• (optional) Layouts + designer script.
• (optional) Paths configuration.
• List of files. Files content is not added.
• List of libraries with additional information for each library.
• Current caret location with the code around it - the AI knows where you are focused on right now.
• Additional information about the IDE and useful links for the AI to find more information.

How to use:
- Click on Ctrl + R. A json file will be created and copied to the clipboard. Paste into the AI assistant and ask questions.

I tested it with several AI platforms and the results are quite good. The answers are mostly to the point. Not always so be cautious.

Other improvements:

• Autocomplete in #If lines:

• Fix for String.ToLower not explicitly setting the locale. Mainly fixes the Turkish I: https://www.b4x.com/android/forum/t...ctly-for-the-turkish-language.163961/#content
• PyBridge template updated.
• New #Macro / comment link options:
  • librariesrefresh - set to True to automatically refresh the libraries after the task runs.
  • codesync - set to True to force the IDE to synchronize the code modules with the files.
  • autosave - set to True to automatically save the project BEFORE running the task. Note that Tools - IDE Options - Auto Save should be enabled for this to have effect.
  • filessync (not new) - set to True to synchronize the Files tab after the task.
  • cleanproject (not new) - set to True to "clean project" after the task
  • %STATE1% - new variable that causes the IDE to create a temporary file with the IDE state based on the new options under Tools - IDE Options. The file path will be passed to the process. This is used by Code Bundle and can be used by other similar tools. Note that the format is not final and can be modified.
• Objects\Temp folder is deleted when cleaning project.
• Json library updated and maps now preserve order when writing or reading.
• Other bug fixes and minor improvements.

Hello Erel, thank you for the new release

Code bundle is working just like previously.

None coding test:
I uploaded the JSON file to Gemini from my nearly production ready professinal business desktop software (37k+ lines of code in the B4J project), and I had a full voice conversation with Gemini about it.

The text you see below, is just a small fractions of the words from the Gemini voice that I can hear. This was part of a five minutes conversation that also included questions and answers, plus a conversatoin on how the fully integrated invoice, quote, stock control, contact management, purchasing, bookkeeping, sales modules, faults, and returns screens all work together. Gemini also talked about how the software can help small to medium size businesses to run smoothly and efficiently, thus helping employees to be more productive. Gemini just kept going which I personally found impressive.

The information in the JSON file really is fully loaded Erel, congratulations on such a great idea. At one point Gemini was even giving me basic direction (about 70% to 80% correct) on how to created invoices, including clicking on the new and saved buttons , seriously impressive.

A Gemini conversation with myself that lasted about 5 minutes or so. Onlookers must have thought that I was going mad or something like that, as I was chatting away to my phone, it was like talking to KITT lol

The next things I asked Gemini to do via the JSON file, was to create a podcast about the software between two people, Gemini did that task with east. Here is part of the chat that I listened too between virtual Sarah and virtual Jake. Using the information in the JSON file, Sarah and Jake had an extremely long conversation regarding my business software. They even talked about the customer sales, purchase orders and debt (money owed) charts incoused in the software, as well as other key features

I just listened and listened and listened to their conversation, it was actually interesting to me.

I didn't even have time to ask Gemini to find any bugs, or to debug anything issues (as I've not seen any myself). I thought to myself what else could I do apart from asking it about code issues what don't really exist.

Tomorrow, I'll switch over to Copilot to see how that a fares.

Very impressive:
I'm more than sure that this feature will come in handy for developers. Not only for the simple tasks like what I've done above, but also for serious diagnostics, finding solutions to developers problems like hopefully debugging issues, asking IA about missing features or what would be good to add to solutions, plus other helpful features that I'm more than sure B4X developers like @aeric, @Magma, @Alessandro71 et al will find extremely useful. I can see developers posting hint on what they use code bundle for, which could in fact be a thread all by itself).

Anyway Erel, this is an excellent feature that I will definitely be exploring in more detail.


Thank you Erel...

From my point of view, the project‑bundle feature is valuable because it gives me the kind of structured, high‑signal context that makes code assistance more accurate, more aligned with the project’s architecture, and less dependent on guesswork. The benefit isn’t that I “need” the whole project to answer syntax questions — it’s that when deeper reasoning is required, the bundle provides the right information in the right shape.

---

How the bundle improves code assistance​

The bundle exposes the project in a way that mirrors how a developer thinks about it:

• Module boundaries are clear, so I can see how responsibilities are divided.
• Handlers, WebSocket classes, and entry points are visible, so I understand the event flow.
• Build configuration and libraries are included, so I know what APIs are available.
• Project‑wide patterns and naming conventions are visible, so generated code can match the existing style.
• The overall architecture is apparent, so I can place new code in the correct location without relying on assumptions.

This is the level of context that allows me to generate additions or modifications that fit naturally into the project rather than feeling bolted on.

---

Why this matters even when the user only needs small things​

Most day‑to‑day questions are local: function signatures, API usage, small code snippets. But when a question touches structure — adding a new handler, extending a class, reorganising logic, or understanding how modules interact — the bundle removes ambiguity. It prevents incorrect assumptions about:

• where new code belongs
• how state is managed
• how modules communicate
• what conventions the project follows

That makes the assistance more reliable and reduces the need for the user to manually provide context.

---

What worked well in the test project​

With the sample project, the bundle made it possible to:

• understand the server setup and routing
• see how the HTTP and WebSocket components relate
• recognise the project’s coding style and match it
• reason about where new features would integrate cleanly

This is exactly the kind of clarity that improves the quality of generated code.

---

Why this is a meaningful addition to B4X tooling​

The feature gives B4X a modern capability that many ecosystems still lack: a structured, machine‑readable representation of the entire project. That enables:

• more accurate code generation
• safer refactoring
• better architectural guidance
• fewer misunderstandings caused by missing context

It’s a foundation that can support increasingly sophisticated AI‑assisted development without requiring changes to how developers write code.

Tip: press Ctrl + R to export IDE state for AI assistants.

The only version that I can get this particular background worker app to compile with in debug mode is OpenJDK...\JDK_V25.0.2\bin\javac.exe, but even the compile windows says that it is infact Java Version: 8, which it isnt.

B4X:

B4J Version: 10.50 BETA #1
Parsing code.    (0.04s)
    Java Version: 8
Building folders structure.    (0.02s)
Compiling code.    (0.11s)
Compiling layouts code.    (0.00s)
Organizing libraries.    (0.00s)
Compiling generated Java code.    (0.01s)
Compiling debugger engine code.    (0.01s)
Running application.    (0.00s)
Completed successfully.

Please note, that this is only happening in debug mode of a background worker app. In debug mode with every other desktop(JFX) app using my default java version which is Java Version: 19, all desktop apps work in both debug and also release mode.

i've gone back to using B4J V10.30 (x64).exe where the background worker app that i'm working on can be compiled and debugged using Java Version: 19, which 10.50 BETA #1 currently will not allow me to do.

I hope that this is enough information to help you clear up this issue. debug_java_modules.txt does clearly exist under B4J V10.30, but t appears that debug_java_nonui_modules.txt does not exist under B4J V10.50 BETA #1.

But saying that, I have absolutely no idea what I'm talking about...

The code bundle tool doesn't do anything else except of creating the bundle file. It has no control over the AI behavior or terms. You can run a local LLM if you want.

Note that your code will not become public domain by uploading it to ChatGPT or similar services. In some cases it can be used to train the model.

Click to expand...

Model “regurgitation” risk (low, but not zero): Any large model can sometimes reproduce snippets it has seen during training, especially if that text appears many times or is very distinctive. Modern systems try to reduce this, but it’s best to assume sensitive or proprietary code should not be uploaded unless you’ve disabled training / are using a business/API plan. (The safest practical stance is: training ≠ sharing, but memorization risk is not literally zero.)

Are you sure that you put JavaFX in the correct place?

Erel said:

JavaFX isn't included with Java since Java 11. If you are not using the Java package from b4x.com, then you need to add JavaFX from https://gluonhq.com/products/javafx/

This is however not related to the beta version, so please start a new thread if need further assistance with it.
