Use this rule to prevent values with octal numbers. In YAML, numbers that
start with ``0`` are interpreted as octal, but this is not always wanted.
For instance ``010`` is the city code of Beijing, and should not be
converted to ``8``.
.. rubric:: Examples
#. With ``octal-values: {forbid-implicit-octal: true}``
the following code snippets would **PASS**:
::
user:
city-code: '010'
the following code snippets would **PASS**:
::
user:
city-code: 010,021
the following code snippets would **FAIL**:
::
user:
city-code: 010
#. With ``octal-values: {forbid-explicit-octal: true}``
the following code snippets would **PASS**:
::
user:
city-code: '0o10'
the following code snippets would **FAIL**:
::
user:
city-code: 0o10
