terraform-documenter

A quick utility for analysing a Terraform directory and outputting Github flavoured Markdown documentation for input and output variables.

The tool can be used to verify the existence of description fields on all input and output variables before outputting (-verify).

Additionally, if a source Markdown file is provided (-source <file>) then the full file will be formatted before being output, with any existing "Inputs/Outputs" section replaced or otherwise appended.
