There is no list of built-in functions (circular avoidance)

[mike-feldmeier]

Terraform Version

v1.10.x (latest)

Affected Pages

https://developer.hashicorp.com/terraform/language/expressions/function-calls
https://developer.hashicorp.com/terraform/language/functions

What is the docs issue?

The "Function Calls" page lists "For a full list of available functions, see the function reference."

The "Functions" page shows a single function (max), and then points back to the "Function Calls" page, promising a "page for all of the available built-in-functions"

"For more details on syntax, see [Function Calls](https://developer.hashicorp.com/terraform/language/expressions/function-calls) in the Expressions section.

The Terraform language does not support user-defined functions, and so only the functions built in to the language are available for use. The documentation includes a page for all of the available built-in functions."

Proposal

Please add a list of available functions and link correctly to them.

The list of functions is in the sidebar, there are too many to repeat on that page. Admittedly, this is not particularly obvious based on where attention is focused on these pages. It also is a bit of a limitation of the way our docs site is structured, and may be unavoidable. I'll refer this to the docs team, they may know a trick to better highlight this.
