👩‍⚕️🤖 docgen

This tool generates JSON that can then be used to generate docs for Overmind sources. The format of the comments is as follows:

//go:generate docgen ./docs
// +overmind:type ec2-instance
// +overmind:descriptiveType EC2 Instance
// +overmind:get Get an EC2 instance by ID
// +overmind:list List all EC2 instances
// +overmind:search Search for EC2 instances by name
// +overmind:group AWS
// +overmind:link ip
// +overmind:link ec2-security-group
// +overmind:terraform:method SEARCH
// +overmind:terraform:queryMap aws_autoscaling_group.name
// +overmind:terraform:scope global

Produces this markdown:

{
  "type": "ec2-instance",
  "descriptiveType": "EC2 Instance",
  "getDescription": "Get an EC2 instance by ID",
  "listDescription": "List all EC2 instances",
  "searchDescription": "Search for EC2 instances by name",
  "group": "AWS",
  "links": [
    "ip",
    "ec2-security-group"
  ]
}

Note that the format of the go generate comment is:

//go:generate docgen {destination_folder}

Where destination_folder is relative to the current file

Comment Tags

All tags gor a given type should exist within the same file, however they can live anywhere withing that file.

Single-Line Tags

These tags must include the desired documentation following the tag on a single line

  • +overmind:type: The type that the source returns e.g. ec2-instance
  • +overmind:descriptiveType: The desriptive type e.g. EC2 Instance
  • +overmind:get: Description of the Get method for this source
  • +overmind:list: Description of the List method for this source
  • +overmind:search: Description of the Search method for this source
  • +overmind:group: The group that this source belongs to e.g. "AWS"
  • +overmind:link: Types of items that this can be linked to
  • +overmind:terraform:method: The method the query should have when converting from a terraform plan to an overmind query. Defaults to GET. Valid values: GET, LIST, SEARCH
  • +overmind:terraform:queryMap: Where the query data should come from when converting a terraform plan to an Overmind query. This is in the format {resource_type}.{attribute_name}. This can be specified multiple times if there are many terrafrom resources taht could affect this overmind type
  • +overmind:terraform:scope: The scope that the query should have when converting from a terraform plan to an Overmind query, defaults to *. This field supports interpolationwhich allows you to interpolate variables in the scope string. Interpolation is done using the Terraform interpolation syntax. These variables can come from the following places:
    • outputs - These are the outputs from the plan
    • values - These are the values from the resource in question
