title: Minimal standards checks
|
||
|
|
---
|
||
|
|
|
||
|
|
A typical standards check will look like:
|
||
|
|
|
||
|
|
{{< highlight Python "linenos=table" >}}
|
||
|
|
def check_playbook_for_something(candidate, settings):
|
||
|
|
result = Result(candidate.path) # empty result is a success with no output
|
||
|
|
with open(candidate.path, 'r') as f:
|
||
|
|
for (lineno, line) in enumerate(f):
|
||
|
|
if line is dodgy:
|
||
|
|
# enumerate is 0-based so add 1 to lineno
|
||
|
|
result.errors.append(Error(lineno+1, "Line is dodgy: reasons"))
|
||
|
|
return result
|
||
|
|
{{< /highlight >}}
|
||
|
|
|
||
|
|
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`).
