[Help] [Molten] Cell not Found

[teimurlu]

Molten cannot find cells and using Quarto produces the following message:

No code chunks found for the current language, which is detected based on the current code block. Is your cursor in a code block?

Below are my plugin.lua files. What am I doing wrong?

I'll copy my response from the closed issue

Also using Quarto complains about code runner not being initialised

You need to run :QuatoActivate probably

Finally Molten cannot find cells.

I assume you're using :MoltenEvaluateCell when a cell doesn't exist yet. Molten cell != markdown/quarto cell.

Molten cells are defined in the molten readme

Is this a correct cell? I use Jupytext to convert the file to markdown format, then I do call :QuatoActivate command. Then I run :MoltenReEvaluateCell and I get the error. I do not get any errors when I run line by line.

When you execute some code, it will create a cell. You can recognize a cell because it will be highlighted when your cursor is in it.

Please read the README. Molten knows nothing about the file format that your code is in
