Yet Another Markup Language

See yq

A superset of [JSON], with comments! Also see [TOML] and HCL

TODO: Document this
LEARN: Because of [Ansible]. [Octopus Deploy] & [[azure_devops_pipelines]]
Some questions have been raised about it’s (or it’s libraries) security.

Wouldn’t it be fun to use Google’s Protocol buffers for this Ansible use case?

Convert to & from JSON via yamljs

npm install -g yamljs

then manipulate with jq

yaml2json octopipe.yaml | jq '.variables[].name'

Example file

From Octopus

variables:
- name: variable1
  value: value1
- name: variable2
  values:
    Dev: dev_value
    Test: test_value
- name: variable3
  value: octopusdeploy-account
  type: AzureAccount
  description: Account used for deployments
project:
  name: OctopusProject
  description: My Octopus Project
  group: OctopusProjectGroup
  lifecycle: OctopusProject.Lifecycle
process:
  steps:
  - name: Init
    type: PowerShell
    file: scripts/init.ps1
  - name: Deploy VM
    type: PowerShell
    file: scripts/deploy.ps1

yaml2json octopus.yaml | jq > y.json && json2yaml -d 10 y.yaml && yq r y.yaml
