This is under a heading "Sensitive Resource Attributes" on the assumption
that if we later stabilize this feature then this heading will live on
with some different content that describes the propagation of sensitive
values from resource attributes, rather than describing the experiment.
The resources, expressions, and modules pages were all split into smaller, more
navigable pages, but the old URLs had accumulated a large number of deep links
to their section headers. To help people recover when they click an old link, we
converted those old URLs to landing pages, which preserve all of the old in-page
anchors and point readers to the appropriate new destinations.
However, because the new link-to-new-page sections are so small, it was kind of
hard to tell which section you had clicked into! Especially if you were near the
bottom of the page and the browser wasn't able to position the desired section
at the very top of the window.
This commit aims to improve that by putting one full screen of whitespace in
between every linkable section on these landing pages. Yes, it's a hack, but
you're meant to only view these pages for three seconds or so before moving on
to the place you wanted to be, and this should help dispel any confusion about
which place that is.
This tutorial uses references to local values, conditional expressions,
and splat expressions, so I've added it to those pages as well as the
expressions overview.
The default cli Warn calls always write to the error writer (stderr by
default), however the output is intended to be viewed in the UI by the
user, rather than in a separate stream. Terraform also generally does
not consider warnings to be errors from the cli point of view, and does
not need to output the warning text to stderr.
By redirecting Warn calls to Output calls at the lowest level in the
main package, we can eliminate the chance that Warn and Output
messages are interleaved, while still allowing the internal `cli.Ui`
implementations to format `Warn` and `Output` calls separately.
