`bot` — Classes for Building Bots#

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:

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.
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.
MultipleSitesBot: An alias of BaseBot. Should not be used if any other bot class is used.
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.
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 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 CurrentPageBot it’s possible to subclass one of the following classes to filter the pages which are ultimately handled by treat_page:

ExistingPageBot: Only handle pages which do exist.
CreatingPageBot: Only handle pages which do not exist.
RedirectPageBot: Only handle pages which are redirect pages.
NoRedirectPageBot: Only handle pages which are not redirect pages.
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 ExistingPageBot and then 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 AutomaticTWSummaryBot which subclasses CurrentPageBot and automatically defines the summary when put_current is used.

bot.critical(msg, text='[deprecated name of msg]', *args, **kwargs)[source]#

Output a critical record to the user with level CRITICAL.

msg will be sent to stderr via pywikibot.userinterfaces. The arguments are interpreted as for logoutput().

class bot.LoggingFormatter(fmt=None, datefmt=None, style='%')[source]#

Bases: Formatter

Format LogRecords for output to file.

Initialize the formatter with specified format strings.

Initialize the formatter either with the specified format string, or a default as described above. Allow for specialized date formatting with the optional datefmt argument. If datefmt is omitted, you get an ISO8601-like (or RFC 3339-like) format.

Use a style parameter of ‘%’, ‘{’ or ‘$’ to specify that you want to use one of %-formatting, str.format() ({}) formatting or string.Template formatting in your format string.

Changed in version 3.2: Added the style parameter.

format(record)[source]#: Strip trailing newlines before outputting text to file.

bot.set_interface(module_name)[source]#

Configures any bots to use the given interface module.

Search for user interface module in the pywikibot.userinterfaces subdirectory and initialize UI. Calls init_handlers() to re-initialize if we were already initialized with another UI.

New in version 6.4.

Parameters:: module_name (str) –
Return type:: None

bot.init_handlers()[source]#

Initialize the handlers and formatters for the logging system.

This relies on the global variable ui which is a UI object.

See also

pywikibot.userinterfaces

Calls writelogheader() after handlers are initialized. This function must be called before using any input/output methods; and must be called again if ui handler is changed. Use set_interface() to set the new interface which initializes it.

Note

this function is called by any user input and output function, so it should normally not need to be called explicitly.

All user output is routed through the logging module. Each type of output is handled by an appropriate handler object. This structure is used to permit eventual development of other user interfaces (GUIs) without modifying the core bot code.

The following output levels are defined:

DEBUG: only for file logging; debugging messages.

STDOUT: output that must be sent to sys.stdout (for bots that may have their output redirected to a file or other destination).

VERBOSE: optional progress information for display to user.

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

INPUT: prompts requiring user response.

WARN: user warning messages.

ERROR: user error messages.

CRITICAL: fatal error messages.

Return type:: str

bot.handle_args(args=None, do_help=True)[source]#

Handle global command line arguments and return the rest as a list.

Takes the command line arguments as strings, processes all global parameters such as -lang or -log, initialises the logging layer, which emits startup information into log at level ‘verbose’. This function makes sure that global arguments are applied first, regardless of the order in which the arguments were given. args may be passed as an argument, thereby overriding sys.argv.

>>> local_args = pywikibot.handle_args()  # sys.argv is used
>>> local_args  
[]
>>> local_args = pywikibot.handle_args(['-simulate', '-myoption'])
>>> local_args  # global optons are handled, show the remaining
['-myoption']
>>> for arg in local_args: pass  # do whatever is wanted with local_args

Changed in version 5.2: -site global option was added

Changed in version 7.1: -cosmetic_changes and -cc may be set directly instead of toggling the value. Refer tools.strtobool() for valid values.

Changed in version 7.7: -config global option was added.

Changed in version 8.0: Short site value can be given if site code is equal to family like -site:meta.

Parameters:

args (Optional[Iterable[str]]) – Command line arguments. If None, pywikibot.argvu is used which is a copy of sys.argv
do_help (bool) – Handle parameter ‘-help’ to show help and invoke sys.exit

Returns:

list of arguments not recognised globally

Return type:

List[str]

bot.show_help(module_name=None, show_global=False)[source]#

Parameters:: page (BasePage) –
Return type:: None

class bot.OptionHandler(**kwargs)[source]#

Bases: object

Class to get and set options.

How to use options of OptionHandler and its BaseBot subclasses: First define an available_options class attribute for your own option handler to define all available options:

>>> default_options = {'foo': 'bar', 'bar': 42, 'baz': False}
>>> class MyHandler(OptionHandler): available_options = default_options

Or you may update the predefined setting in the class initializer. BaseBot predefines a ‘always’ options and sets it to False:

self.available_options.update(always=True, another_option=’Yes’)

Now you can instantiate an OptionHandler or BaseBot class passing options other than default values:

>>> bot = MyHandler(baz=True)

You can access bot options either as keyword item or attribute:

>>> bot.opt.foo
'bar'
>>> bot.opt['bar']
42
>>> bot.opt.baz  # default was overridden
True

You can set the options in the same way:

>>> bot.opt.bar = 4711
>>> bot.opt['baz'] = None
>>>

Or you can use the option as a dict:

>>> 'Option opt.{foo} is {bar}'.format_map(bot.opt)
'Option opt.bar is 4711'

Warning

You must not access bot options as an attribute if the keyword is a dict method.

Only accept options defined in available_options.

Parameters:: kwargs (Any) – bot options

available_options: Dict[str, Any] = {}#: Handler configuration attribute. Only the keys of the dict can be passed as __init__ options. The values are the default values. Overwrite this in subclasses!

set_options(**options)[source]#

Set the instance options.

Parameters:: options (Any) –
Return type:: None

class bot.BaseBot(**kwargs)[source]#

Bases: OptionHandler

Generic Bot to be subclassed.

Only accepts generator and options defined in available_options.

This class provides a run() method for basic processing of a generator one page at a time.

If the subclass places a page generator in self.generator, Bot will process each page in the generator, invoking the method treat() which must then be implemented by subclasses.

Each item processed by treat() must be a page.BasePage type. Use init_page() to upcast the type. To enable other types, set BaseBot.treat_page_type to an appropriate type; your bot should derive from BaseBot in that case and handle site properties.

If the subclass does not set a generator, or does not override treat() or run(), NotImplementedError is raised.

For bot options handling refer OptionHandler class above.

Changed in version 7.0: A counter instance variable is provided.

Parameters:: kwargs (Any) – bot options
