Andrew Imeson 404656394c docs: Explicitly specify language even when it's plain text
rstcheck succeeds with a failure (heh) when there's a code block without
a language specified. This can lead to false negatives as the file is no
longer being checked by rstcheck.

Error:

    An `AttributeError` error occured. This is most propably due to a
    code block directive (code/code-block/sourcecode) without a
    specified language. This may result in a false negative for source:
    'docs/disable_with_comments.rst'. See
    https://rstcheck-core.readthedocs.io/en/latest/faq/#code-blocks-without-language-sphinx
    for more information.  Success! No issues detected.

Disable with comments
=====================
Disabling checks for a specific line
------------------------------------
To prevent yamllint from reporting problems for a specific line, add a
directive comment (``# yamllint disable-line ...``) on that line, or on the
line above. For instance:
.. code-block:: yaml
# The following mapping contains the same key twice,
# but I know what I'm doing:
key: value 1
key: value 2 # yamllint disable-line rule:key-duplicates
- This line is waaaaaaaaaay too long but yamllint will not report anything about it. # yamllint disable-line rule:line-length
This line will be checked by yamllint.
or:
.. code-block:: yaml
# The following mapping contains the same key twice,
# but I know what I'm doing:
key: value 1
# yamllint disable-line rule:key-duplicates
key: value 2
# yamllint disable-line rule:line-length
- This line is waaaaaaaaaay too long but yamllint will not report anything about it.
This line will be checked by yamllint.
It is possible, although not recommend, to disabled **all** rules for a
specific line:
.. code-block:: yaml
# yamllint disable-line
- { all : rules ,are disabled for this line}
You can't make yamllint ignore invalid YAML syntax on a line (which generates a
`syntax error`), such as when templating a YAML file with Jinja. In some cases,
you can workaround this by putting the templating syntax in a YAML comment. See
`Putting template flow control in comments`_.
If you need to disable multiple rules, it is allowed to chain rules like this:
``# yamllint disable-line rule:hyphens rule:commas rule:indentation``.
Disabling checks for all (or part of) the file
----------------------------------------------
To prevent yamllint from reporting problems for the whole file, or for a block
of lines within the file, use ``# yamllint disable ...`` and ``# yamllint
enable ...`` directive comments. For instance:
.. code-block:: yaml
# yamllint disable rule:colons
- Lorem : ipsum
dolor : sit amet,
consectetur : adipiscing elit
# yamllint enable rule:colons
- rest of the document...
It is possible, although not recommend, to disabled **all** rules:
.. code-block:: yaml
# yamllint disable
- Lorem :
ipsum:
dolor : [ sit,amet]
- consectetur : adipiscing elit
# yamllint enable
If you need to disable multiple rules, it is allowed to chain rules like this:
``# yamllint disable rule:hyphens rule:commas rule:indentation``.
Disabling all checks for a file
-------------------------------
To prevent yamllint from reporting problems for a specific file, add the
directive comment ``# yamllint disable-file`` as the first line of the file.
For instance:
.. code-block:: yaml
# yamllint disable-file
# The following mapping contains the same key twice, but I know what I'm doing:
key: value 1
key: value 2
- This line is waaaaaaaaaay too long but yamllint will not report anything about it.
or:
.. code-block:: jinja
# yamllint disable-file
# This file is not valid YAML because it is a Jinja template
{% if extra_info %}
key1: value1
{% endif %}
key2: value2
Putting template flow control in comments
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Alternatively for templating you can wrap the template statements in comments
to make it a valid YAML file. As long as the templating language doesn't use
the same comment symbol, it should be a valid template and valid YAML (pre and
post-template processing).
Example of a Jinja2 code that cannot be parsed as YAML because it contains
invalid tokens ``{%`` and ``%}``:
.. code-block:: text
# This file IS NOT valid YAML and will produce syntax errors
{% if extra_info %}
key1: value1
{% endif %}
key2: value2
But it can be fixed using YAML comments:
.. code-block:: yaml
# This file IS valid YAML because the Jinja is in a YAML comment
# {% if extra_info %}
key1: value1
# {% endif %}
key2: value2
