Is there a reason why Livebook secrets are automatically prepended with LB?

—skip—

I see no reason other than well intended namespacing…with confusion as result.

I think one of the reasons is that a defined namespace allows Livebook to detect “environment variables” that Livebook is supposed to manage and give them special treatment.

Here’s a quick GIF video showing that difference:

If that’s all there is to it, a simple helper text in the config modal would clarify.

This secret can be fetched with System.fetch_env!(“LB_SOME”)

@dmitriid maybe open issue marked as “usability issue”?

I didn’t think it warranted an issue, but I might just do that the next time I run into this

Added an issue: [Usability] Help text/popup/description that env variables are prefixed with LB_ · Issue #1827 · livebook-dev/livebook · GitHub

And while writing it discovered that there’s help text, but I never saw it
