Add `--layout` flag to `marimo run` -- or perhaps just a documentation issue?

[stephenlf]

Description

I would like to serve my notebook in slides mode. The notebook has dependencies that make it impossible to export as a WASM file.

Suggested solution

Add support for a --layout flag in the CLI command marimo run

Edit: Solution

Updating this PR with information from the comments below.

This is already possible. I needed to include the "layouts/" folder in my deployment. I could have verified that it was set up correctly by noting:

1. "my_notebook.md" has this line (note the layout_file argument):

# Autogenerated by Marimo; specified layout file
app = marimo.App(layout_file="layouts/my_notebook.slides.json") 

2. layouts/my_notebook.slides.json exists.

$ cat layouts/my_notebook.slides.json
{
  "type": "slides",
  "data": {}
}

Update - it looks like maybe including the layouts/mynotebook.slides.json in the deployment resolves this issue? Is that the intended approach?

@stephenlf yes, for layouts to take effect, you need the layout files. this is true for both Grid and Slides. in the case of slides.json, there is not much (yet) since we don't support customizing slides.

If you'd like, we'd appreciate a PR to our docs to make this clearer

Also interested in this. It'd be great if user can set marimo run --layout slides notebook.py. Deploying a notebook as a presentation is very helpful.

@sghng, this is already possible. you just need to include the layouts directory in your deployment files
