====
Doc8
====
Doc8 is an *opinionated* style checker for `rst`_ (with basic support for
plain text) styles of documentation.
QuickStart
==========
::
pip install doc8
To run doc8 just invoke it against any doc directory::
$ doc8 coolproject/docs
Usage
=====
Command line usage
******************
::
$ doc8 -h
usage: doc8 [-h] [--config path] [--allow-long-titles] [--ignore code]
[--no-sphinx] [--ignore-path path] [--ignore-path-errors path]
[--default-extension extension] [--file-encoding encoding]
[--max-line-length int] [-e extension] [-v] [--version]
[path [path ...]]
Check documentation for simple style requirements.
What is checked:
- invalid rst format - D000
- lines should not be longer than 79 characters - D001
- RST exception: line with no whitespace except in the beginning
- RST exception: lines with http or https urls
- RST exception: literal blocks
- RST exception: rst target directives
- no trailing whitespace - D002
- no tabulation for indentation - D003
- no carriage returns (use unix newlines) - D004
- no newline at end of file - D005
positional arguments:
path Path to scan for doc files (default: current
directory).
optional arguments:
-h, --help show this help message and exit
--config path user config file location (default: doc8.ini, tox.ini,
pep8.ini, setup.cfg).
--allow-long-titles allow long section titles (default: false).
--ignore code ignore the given error code(s).
--no-sphinx do not ignore sphinx specific false positives.
--ignore-path path ignore the given directory or file (globs are
supported).
--ignore-path-errors path
ignore the given specific errors in the provided file.
--default-extension extension
default file extension to use when a file is found
without a file extension.
--file-encoding encoding
override encoding to use when attempting to determine
an input files text encoding (providing this avoids
using `chardet` to automatically detect encoding/s)
--max-line-length int
maximum allowed line length (default: 79).
-e extension, --extension extension
check file extensions of the given type (default:
.rst, .txt).
-q, --quiet only print violations
-v, --verbose run in verbose mode.
--version show the version and exit.
Ini file usage
**************
Instead of using the CLI for options the following files will also be examined
for ``[doc8]`` sections that can also provided the same set of options. If
the ``--config path`` option is used these files will **not** be scanned for
the current working directory and that configuration path will be used
instead.
* ``$CWD/doc8.ini``
* ``$CWD/tox.ini``
* ``$CWD/pep8.ini``
* ``$CWD/setup.cfg``
An example section that can be placed into one of these files::
[doc8]
ignore-path=/tmp/stuff,/tmp/other_stuff
max-line-length=99
verbose=1
ignore-path-errors=/tmp/other_thing.rst;D001;D002
**Note:** The option names are the same as the command line ones (with the
only variation of this being the ``no-sphinx`` option which from
configuration file will be ``sphinx`` instead).
Option conflict resolution
**************************
When the same option is passed on the command line and also via configuration
files the following strategies are applied to resolve these types
of conflicts.
====================== =========== ========
Option Overrides Merges
====================== =========== ========
``allow-long-titles`` Yes No
``ignore-path-errors`` No Yes
``default-extension`` Yes No
``extension`` No Yes
``ignore-path`` No Yes
``ignore`` No Yes
``max-line-length`` Yes No
``file-encoding`` Yes No
``sphinx`` Yes No
====================== =========== ========
**Note:** In the above table the configuration file option when specified as
*overrides* will replace the same option given via the command line. When
*merges* is stated then the option will be combined with the command line
option (for example by becoming a larger list or set of values that contains
the values passed on the command line *and* the values passed via
configuration).
