"""
User-interface related functions for building bots.

This module supports several different bot classes which could be used in
conjunction. Each bot should subclass at least one of these four classes:

* :py:obj:`BaseBot`: Basic bot class in case where the site is handled
  differently, like working on multiple sites in parallel. No site
  attribute is provided. Instead site of the current page should be used.
  This class should normally not be used directly.

* :py:obj:`SingleSiteBot`: Bot class which should only be run on a
  single site. They usually store site specific content and thus can't
  be easily run when the generator returns a page on another site. It
  has a property ``site`` which can also be changed. If the generator
  returns a page of a different site it'll skip that page.

* :py:obj:`MultipleSitesBot`: An alias of :py:obj:`BaseBot`. Should not
  be used if any other bot class is used.

* :py:obj:`ConfigParserBot`: Bot class which supports reading options from a
  scripts.ini configuration file. That file consists of sections, led by a
  ``[section]`` header and followed by ``option: value`` or ``option=value``
  entries. The section is the script name without .py suffix. All options
  identified must be predefined in available_options dictionary.

* :py:obj:`Bot`: The previous base class which should be avoided. This
  class is mainly used for bots which work with Wikibase or together
  with an image repository.

Additionally there is the :py:obj:`CurrentPageBot` class which
automatically sets the current page to the page treated. It is
recommended to use this class and to use ``treat_page`` instead of
``treat`` and ``put_current`` instead of ``userPut``. It by default
subclasses the ``BaseBot`` class.

With :py:obj:`CurrentPageBot` it's possible to subclass one of the
following classes to filter the pages which are ultimately handled by
``treat_page``:

* :py:obj:`ExistingPageBot`: Only handle pages which do exist.
* :py:obj:`CreatingPageBot`: Only handle pages which do not exist.
* :py:obj:`RedirectPageBot`: Only handle pages which are redirect pages.
* :py:obj:`NoRedirectPageBot`: Only handle pages which are not redirect pages.
* :py:obj:`FollowRedirectPageBot`: If the generator returns a redirect
  page it'll follow the redirect and instead work on the redirected class.

It is possible to combine filters by subclassing multiple of them. They are
new-style classes so when a class is first subclassing
:py:obj:`ExistingPageBot` and then :py:obj:`FollowRedirectPageBot` it
will also work on pages which do not exist when a redirect pointed to
that. If the order is inversed it'll first follow them and then check
whether they exist.

Additionally there is the :py:obj:`AutomaticTWSummaryBot` which subclasses
:py:obj:`CurrentPageBot` and automatically defines the summary when
``put_current`` is used.

GLOBAL OPTIONS
==============
(Global arguments available for all bots)

-dir:PATH         Read the bot's configuration data from directory given
                  by PATH, instead of from the default directory.

-config:xyn       The user config filename. Default is user-config.py.

-lang:xx          Set the language of the wiki you want to work on,
                  overriding the configuration in user config file.
                  xx should be the site code.

-family:xyz       Set the family of the wiki you want to work on, e.g.
                  wikipedia, wiktionary, wikivoyage, ... This will
                  override the configuration in user config file.

-site:xyz:xx      Set the wiki site you want to work on, e.g.
                  wikipedia:test, wiktionary:de, wikivoyage:en, ... This
                  will override the configuration in user config file.

-user:xyz         Log in as user 'xyz' instead of the default username.

-daemonize:xyz    Immediately return control to the terminal and redirect
                  stdout and stderr to file xyz.
                  (only use for bots that require no input from stdin).

-help             Show this help text.

-log              Enable the log file, using the default filename
                  '{}-bot.log'
                  Logs will be stored in the logs subdirectory.

-log:xyz          Enable the log file, using 'xyz' as the filename.

-nolog            Disable the log file (if it is enabled by default).
                  Also disable command.log.

-maxlag           Sets a new maxlag parameter to a number of seconds.
                  Defer bot edits during periods of database server lag.
                  Default is set by config.py

-putthrottle:n    Set the minimum time (in seconds) the bot will wait
-pt:n             between saving pages.
-put_throttle:n

-debug:item       Enable the log file and include extensive debugging
-debug            data for component "item" (for all components if the
                  second form is used).

-verbose          Have the bot provide additional console output that may be
-v                useful in debugging.

-cosmeticchanges  Toggles the cosmetic_changes setting made in config.py
-cc               or user config file to its inverse and overrules it.
                  All other settings and restrictions are untouched. The
                  setting may also be given directly like `-cc:True`;
                  accepted values for the option are `1`, `yes`, `true`,
                  `on`, `y`, `t` for True and `0`, `no`, `false`, `off`,
                  `n`, `f` for False. Values are case-insensitive.

-simulate         Disables writing to the server. Useful for testing and
                  debugging of new code (if given, doesn't do any real
                  changes, but only shows what would have been changed).
                  An integer or float value may be given to simulate a
                  processing time; the bot just waits for given seconds.

-<config var>:n   You may use all given numeric config variables as
                  option and modify it with command line.

     - VERBOSE: optional progress information for display to user.
     - INFO: normal (non-optional) progress information for display to user.
