I don't know if it's enough.
Maybe a dedicated section about the behavior of turbo when a LiveAction of a Live Component is returning a RedirectResponse should be more appropriate ?

I'm not sure to understand the RST Linter failing.
Executing locally the command docker run --rm -it -e DOCS_DIR='/docs' -v ${PWD}:/docs oskarstark/doctor-rst -vvv as mentioned in the CONTRIBUTING.md#working-on-documentation didn't trigger any error.

Hi, here some explanations:

1. for the error Please ensure title "Downloading files" and underline length are matching, it means that the title Downloading files and the underline (usually --------(...), or ~~~~~~~(...)) does not have the same length
2. for the error Please add 4 spaces for every indention., it looks like there is a space missing for each lines you added in the code blocks.

For the docker run ... from the documentation, I believe you must adjust the DOCS_DIR env variable to point to src/LiveComponent/doc.

Hi @Kocal and thanks.

I don't want to pollute this PR with a non related topic but before fixing the index.rst file for the errors triggered by the github RST Linter check, here is what the local command was outputting before and after the fix.

docker run --rm -it -e DOCS_DIR='/symfony-ux' -v ${PWD}:/symfony-ux oskarstark/doctor-rst -vvv

 [OK] All files are valid!         

For testing purpose in order to see if the .doctor-rst.yaml was correctly loaded and the *.rst file where checked, when uncommenting some currently commented rules in the .doctor-rst.yaml the checks failed "as expected".
So, i still don't understand why the rules underline length are matching and 4 spaces for every indention where not triggered locally.

Minor comments on the code examples, and it should be good.

About the disparities between the local order and the CI, I don't really know, maybe the container version is different? Let's continue talking about this in a dedicated issue. Thanks 🙏🏻

Status: Needs Work

[zefyx]

Sorry for missing the unrelated modification introduced with the commit 99d3d21
the reStructuredText formatter of the IDE automatically removed the 2 white spaces when saving.
(consistent but not related to the current PR)

[smnandre]

The small note to remove and let's merge this! 😄

Thanks @zefyx.
