All standards check take a candidate object, which has a path attribute. The type can be inferred from the class name (i.e. `type(candidate).__name__`) or from the table [here](#candidates).
They return a `Result` object, which contains a possibly empty list of `Error` objects. `Error` objects are formed of a line number and a message. If the error applies to the whole file being reviewed, set the line number to `None`. Line numbers are important as `ansible-later` can review just ranges of files to only review changes (e.g. through piping the output of `git diff` to `ansible-later`).
They return a `Result` object, which contains a possibly empty list of `Error` objects. `Error` objects are formed of a line number and a message. If the error applies to the whole file being reviewed, set the line number to `None`.

title: The standards file
---
A standards file comprises a list of standards, and optionally some methods to
check those standards.
Create a file called standards.py (this can import other modules)
<!-- prettier-ignore-start -->
<!-- spellchecker-disable -->
{{< highlight Python "linenos=table" >}}
from ansiblelater include Standard, Result
tasks_are_uniquely_named = Standard(dict(
# ID's are optional but if you use ID's they have to be unique
id="ANSIBLE0003",
# Short description of the standard goal
name="Tasks and handlers must be uniquely named within a single file",
check=check_unique_named_task,
version="0.1",
types=["playbook", "task", "handler"],
))
standards = [
tasks_are_uniquely_named,
role_must_contain_meta_main,
]
{{< /highlight >}}
<!-- spellchecker-enable -->
<!-- prettier-ignore-end -->
When you add new standards, you should increment the version of your standards. Your playbooks and roles should declare what version of standards you are using, otherwise ansible-later assumes you're using the latest. The declaration is done by adding standards version as first line in the file.
<!-- prettier-ignore-start -->
<!-- markdownlint-disable -->
<!-- spellchecker-disable -->
{{< highlight INI "linenos=table" >}}
# Standards: 1.2
{{< /highlight >}}
<!-- spellchecker-enable -->
<!-- markdownlint-restore -->
<!-- prettier-ignore-end -->
To add standards that are advisory, don't set the version. These will cause a message to be displayed but won't constitute a failure. When a standard version is higher than declared version, a message will be displayed 'WARN: Future standard' and won't constitute a failure.
An example standards file is available [here](https://github.com/thegeeklab/ansible-later/blob/main/ansiblelater/data/standards.py).
If you only want to check one or two standards quickly (perhaps you want to review your entire code base for deprecated bare words), you can use the `-s` flag with the name of your standard. You can pass `-s` multiple times.
<!-- prettier-ignore-start -->
<!-- spellchecker-disable -->
{{< highlight Shell "linenos=table" >}}
git ls-files | xargs ansible-later -s "bare words are deprecated for with_items"
{{< /highlight >}}
<!-- spellchecker-enable -->
<!-- prettier-ignore-end -->
You can see the name of the standards being checked for each different file by running `ansible-later` with the `-v` option.
