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:



Note: The option names are the same as the command line ones but instead of dashes underscores are used instead (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
extension No Yes
ignore-path No Yes
ignore No Yes
max-line-length 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).
