So far the output command has had a default output format intended for human consumption and a JSON output format intended for machine consumption. However, until Terraform v0.14 the default output format for primitive types happened to be _almost_ a raw string representation of the value, and so users started using that as a more convenient way to access primitive-typed output values from shell scripts, avoiding the need to also use a tool like "jq" to decode the JSON. Recognizing that primitive-typed output values are common and that processing them with shell scripts is common, this commit introduces a new -raw mode which is explicitly intended for that use-case, guaranteeing that the result will always be the direct result of a string conversion of the output value, or an error if no such conversion is possible. Our policy elsewhere in Terraform is that we always use JSON for machine-readable output. We adopted that policy because our other machine-readable output has typically been complex data structures rather than single primitive values. A special mode seems justified for output values because it is common for root module output values to be just strings, and so it's pragmatic to offer access to the raw value directly rather than requiring a round-trip through JSON. |

Terraform Documentation
This directory contains the portions of the Terraform website that pertain to the core functionality, excluding providers and the overall configuration.
The files in this directory are intended to be used in conjunction with
the terraform-website repository, which brings all of the
different documentation sources together and contains the scripts for testing and building the site as
a whole.
