headless code generator

[Chi Ng]

Hi,

I was quite excited about the generator presented in this video from the 2023 summit:

I'm curious about which version of Blockly the headless generator is available in. I couldn't find any documentation related to it.

Many thanks,

Hi Chi,

Thanks for your interest in that generator demo. That was a technical demo of a different way of doing headless generation, but adding it to the library is not currently on the roadmap: if we added it, we would have to support two different types of generators. 

However, you can use our existing generators just fine with a headless workspace. There's a demo here which includes a link to the code that's running.

Cheers,

Rachel

Hi Rachel,

The core version of the generator requires importing Blockly and the Workspace class, which results in the transpiled bundle including a reference to the document object.

I have a Flutter app in which I want to generate code from serialized workspace JSON using flutterjs—an embedded JS engine.

The new generator seems perfect for my use case. Is the new generator open source?

Thanks,

-- Chi

Hi Chi,

Does that mean that Blockly's doesn't work headlessly for you, such as in Node? If yes, that's a regression, so please file a bug with your repro case.

Neil's generator is probably open source--I've CCed him to comment.

Cheers,

Rachel

Hi Rachel,

Thank you for taking the time to answer my questions.

I haven't tried running the generator headless with Node.js yet. I suppose it should work since V8 is embedded in it. 

I will try it when I get around to it, and if I discover anything, I will let you know.

Many thanks,
