Ft/read languages from repo data source

[vini-mw]

Description

Reading and adding the languages attribute to the opslevel_repository data source.

the intended use here is for people to be able to programatically read the languages of any one repo, detect the language with the highest coverage, and assign it to the opslevel_service resource corresponding with the repo.

use case example:

locals {
  // identify the highest coverage out of all detected languages
  highest_lang_coverage = max([for k, v in data.opslevel_repository.this.languages : tonumber(v.usage)]...)
  // find the object of the language w the highest coverage from the returned list of languages by using the previously identified highest coverage number
  main_repo_language = element([for k, v in data.opslevel_repository.this.languages : v if lookup(v, "usage") == tostring(local.highest_lang_coverage)], 0)
}

data "opslevel_repository" "this" {
  alias = "github.com:cool-org/cool-service"
}

resource "opslevel_service" "this" {
  name = "cool-service"

  lifecycle_alias = data.opslevel_lifecycle.this.alias
  tier_alias      = data.opslevel_tier.this.alias
  owner           = opslevel_team.cool-team.id

  // set language using the newly added datasource output
  language = local.main_repo_language.name
}

// attach repo to service
resource "opslevel_service_repository" "this" {
  service    = opslevel_service.this.id
  repository = data.opslevel_repository.this.id

  name           = "cool-service"
  base_directory = "/"
}

this method allows us to populate the language attribute of the service efficiently. as even if a repo is attached to a service (like i do with the opslevel_service_repository resource in the example above), the service will not inherit the available language details of the repository.

Changelog

• [ ] add a new output (languages) to the opslevel_repository data source
• [ ] format the output into a list of objects.
• [ ] update repository data source docs as per the change

data source languages output

output "data" {
  value = data.opslevel_repository.this.languages
}

result in:

Outputs:

data = tolist([
  {
    "name" = "HCL"
    "usage" = "0.55404"
  },

    "name" = "JavaScript"
    "usage" = "0.07078"
