Get current session id.

[clsource]

Hello,
Is there a way to get the current session id?

for example we have __DIR__.

Maybe another variable can be used as __LIVEBOOK_SESSION__ or similar?.

Thanks

What is the use case? It isn’t possible but we would like to understand what it would be used for. :)

Thanks :)

I have a list of livebook files and using Kino to render a table (this code was abstracted and imported from a dep).

I need this because rendering using Kino it generates weird url when using relative href

the element is

this is what I should see (rendering with a markdown cell)

I think this is something related to iframes and that the browser is messing up the relative urls.

If for example I could create the full url using a helper from server side, this can be overcome.

Maybe inside the env?

System.fetch_env!("LIVEBOOK_SESSION_ID")
System.fetch_env!("LIVEBOOK_PORT")
System.fetch_env!("LIVEBOOK_HOST")

Hey @clsource!

You can use relative path in the notebook directly, for example in index.livemd you can have [Chapter 1](./chapter_1.livemd). Clicking on the link will automatically go to that notebook (open it if necessary). It also works when importing notebooks from GitHub/ExDoc.

If you need to generate links dynamically, it should work inside Kino.Markdown. However, the links won't work inside a custom Kino.JS component, because those are inside an iframe and clicking a link inside an iframe would navigate within that iframe either way, which is not what we want.

Thanks!.

But using Kino.Markdown.new instead, is generating another wrong url without the session

Ok so in my findings I think there is a problem when using <a> tags directly in Markdown rendering

[Good URL](#{relative_level1})
<a href="#{relative_level1}">Bad URL</a>

Ah, that makes sense, we only rewrite the urls in markdown elements. #1491 generalizes it :)

There is a difference on rendering markdown links with html links.
For now the solution is always using markdown links.
