This would move the `when` task further away from the rest of the task properties. A `when` from the last task inside the block can +easily be confused as being at the block level, or the reverse. When tasks are +moved from one location to another, there is a real risk of moving the block +level when with it. + +By putting the `when` before the `block`, we avoid that kind of risk. The same risk applies to any simple property at the task level, so that is why +we concluded that the block keys must be the last ones. + +Another common practice was to put `tags` as the last property.

See the section below for details. + +As these schemas are still experimental, creating pull requests to improve the +schema is of much greater help. Though you are still welcome to report bugs but +expect them to take a long time until someone finds time to fix them. + +If you want to help improve the schemas, have a look at the +[development documentation](CONTRIBUTING.md). + +## Schema Bundle + +We are currently migrating towards a single [ansible.json](/f/ansible.json) +schema bundle, one that contains subschema definitions for all the supported +file types. + +To configure your validator or editor to use the bundle, use the new URLs below, +the part after the `#` in the URLs is essential for informing the loader about +which subschema to use. You can also look at our +[settings.json](.vscode/settings.json) to understand how to configure the +[vscode-yaml](https://marketplace.visualstudio.com/items?itemName=redhat.vscode-yaml) +extension. + +- [playbook subschema url](https://raw.githubusercontent.com/ansible-lint/main/src/ansiblelint/schemas/ansible.json#/$defs/playbook) +- [tasks subschema uri](https://raw.githubusercontent.com/ansible-lint/main/src/ansiblelint/schemas/ansible.json#/$defs/tasks) + +## Jinja2 implicit vs explicit templating + +While Ansible might allow you to combine implicit and explicit templating, our +schema will not. Our schemas will only allow you to use the recommended form, +either by forbidding you to use the curly braces on implicit ones or forcing you +to add them on explicit ones. + +Examples: + +```yaml +- name: some task + command: echo 123 + register: result + vars: + become_method_var: sudo + become_method: become_method_var # <-- schema will not allow this + # become_method: "{{ become_method_var }}" # <-- that is allowed +``` + +### How to find if a field is implicit or explicit? + +Run assuming that your keyword is `no_log`, you can run +`ansible-doc -t keyword no_log`, which will give you the following output: + +```yaml +failed_when: + applies_to: + - Task + description: + Conditional expression that overrides the task's normal 'failed' status. + priority: 0 + template: implicit + type: list +``` + +As you can see the `template` field tells you if is implicit or explicit. + +Being more restrictive, schema protects you from common accidents, like writing +a simple string in an explicit field. That will always evaluate as true instead +of being evaluated as a jinja template. + +## Activating the schemas + +At this moment installing +[Ansible VS Code Extension by Red Hat](https://marketplace.visualstudio.com/items?itemName=redhat.ansible) +will activate these schemas. The file patterns used to trigger their use can be +seen +[here](https://github.com/ansible-community/vscode-ansible/blob/master/package.json#L44-L94) + +Because these schemas are generic, you can easily use them with any validators +that support them. diff --git a/src/ansiblelint/schemas/__init__.py b/src/ansiblelint/schemas/__init__.py new file mode 100644 index 0000000..bc93fe4 --- /dev/null
