``Bot`` and ``BotConfig``
~~~~~~~~~~~~~~~~~~~~~~~~~

- ``bot.wiki``: entry into `the Wiki Toolset`_, explained below.
`earwigbot.bot.Bot`_ is EarwigBot's main class. You don't have to instantiate
this yourself, but it's good to be familiar with its attributes and methods,
because it is the main way to communicate with other parts of the bot. A
``Bot`` object is accessible as an attribute of commands and tasks (i.e.,
``self.bot``).

The most useful attributes are:

- ``bot.config``: an instance of ``BotConfig``, for accessing the bot's
configuration data (see below).

- ``bot.commands``: the bot's ``CommandManager``, which is used internally to
run IRC commands (through ``bot.commands.call()``, which you shouldn't have
to use); you can safely reload all commands with ``bot.commands.load()``.

- ``bot.tasks``: the bot's ``TaskManager``, which can be used to start tasks
with ``bot.tasks.start(task_name, **kwargs)``. ``bot.tasks.load()`` can be
used to safely reload all tasks.

- ``bot.frontend`` / ``bot.watcher``: instances of ``earwigbot.irc.Frontend``
and ``earwigbot.irc.Watcher``, respectively, which represent the bot's
connections to these two servers; you can, for example, send a message to the
frontend with ``bot.frontend.say(chan, msg)`` (more on communicating with IRC
below).

- ``bot.wiki``: interface with `the Wiki Toolset`_ (see below).

XXX: TODO
- Finally, ``bot.restart()`` (restarts IRC components and reloads config,
commands, and tasks) and ``bot.stop()`` can be used almost anywhere. Both
take an optional "reason" that will be logged and used as the quit message
when disconnecting from IRC.

`earwigbot.config.BotConfig`_ stores configuration information for the bot. Its
``__doc__``string explains what each attribute is used for, but essentially
each "node" (one of ``config.components``, ``wiki``, ``tasks``, ``irc``, or
``metadata``) maps to a section of the bot's ``config.yml`` file. For example,
if ``config.yml`` includes something like::

irc:
frontend:
nick: MyAwesomeBot
channels:
- "##earwigbot"
- "#channel"
- "#other-channel"

...then ``config.irc["frontend"]["nick"]`` will be ``"MyAwesomeBot"`` and
``config.irc["frontend"]["channels"]`` will be ``["##earwigbot", "#channel",

EarwigBot's answer to the `Pywikipedia framework`_ is the Wiki Toolset
(``earwigbot.wiki``), which you will mainly access through ``bot.wiki``.

XXX: TODO
``bot.wiki`` provides three methods for the management of Sites -
``get_site()``, ``add_site()``, and ``remove_site()``. Sites are objects that
simply represent a MediaWiki site. A single instance of EarwigBot (i.e. a
single *working directory*) is expected to relate to a single site or group of
sites using the same login info (like all WMF wikis with CentralAuth).

Load your default site (the one that you picked during setup) with
``site = bot.wiki.get_site()``.

Dealing with other sites
^^^^^^^^^^^^^^^^^^^^^^^^

*Skip this section if you're only working with one site.*

If a site is *already known to the bot* (meaning that it is stored in the
``sites.db`` file, which includes just your default wiki at first), you can
load a site with ``site = bot.wiki.get_site(name)``, where ``name`` might be
``"enwiki"`` or ``"frwiktionary"`` (you can also do
``site = bot.wiki.get_site(project="wikipedia", lang="en")``). Recall that not
giving any arguments to ``get_site()`` will return the default site.

``add_site()`` is used to add new sites to the sites database. It may be called
with similar arguments as ``get_site()``, but the difference is important.
``get_site()`` only needs enough information to identify the site in its
database, which is usually just its name; the database stores all other
necessary connection info. With ``add_site()``, you need to provide enough
connection info so the toolset can successfully access the site's API/SQL
databases and store that information for later. That might not be much; for
WMF wikis, you can usually use code like this::

project, lang = "wikipedia", "es"
try:
site = bot.wiki.get_site(project=project, lang=lang)
except earwigbot.SiteNotFoundError:
# Load site info from http://es.wikipedia.org/w/api.php:
site = bot.wiki.add_site(project=project, lang=lang)

This works because EarwigBot assumes that the URL for the site is
``"//{lang}.{project}.org"`` and the API is at ``/w/api.php``; this might
change if you're dealing with non-WMF wikis, where the code might look
something more like::

project, lang = "mywiki", "it"
try:
site = bot.wiki.get_site(project=project, lang=lang)
except earwigbot.SiteNotFoundError:
Load site info from http://mysite.net/mywiki/it/s/api.php:
base_url = "http://mysite.net/" + project + "/" + lang
db_name = lang + project + "_p"
sql = {host: "sql.mysite.net", db: db_name}
site = bot.wiki.add_site(base_url=base_url, script_path="/s", sql=sql)

``remove_site()`` does the opposite of ``add_site()``: give it a site's name
or a project/lang pair like ``get_site()`` takes, and it'll remove that site
from the sites database.

Sites
^^^^^

``Site`` objects provide the following attributes:

- ``name``: the site's name (or "wikiid"), like ``"enwiki"``
- ``project``: the site's project name, like ``"wikipedia"``
- ``lang``: the site's language code, like ``"en"``
- ``domain``: the site's web domain, like ``"en.wikipedia.org"``

and the following methods:

- ``api_query(**kwargs)``: does an API query with the given keyword arguments
as params
- ``sql_query(query, params=(), ...)``: does an SQL query and yields its
results (as a generator)
- ``get_replag()``: returns the estimated database replication lag (if we have
the site's SQL connection info)
- ``namespace_id_to_name(id, all=False)``: given a namespace ID, returns the
primary associated namespace name (or a list of all names when ``all`` is
``True``)
- ``namespace_name_to_id(name)``: given a namespace name, returns the
associated namespace ID
- ``get_page(title, follow_redirects=False)``: returns a ``Page`` object for
the given title (or a ``Category`` object if the page's namespace is
"``Category:``")
- ``get_category(catname, follow_redirects=False)``: returns a ``Category``
object for the given title (sans namespace)
- ``get_user(username)``: returns a ``User`` object for the given username

Pages (and Categories)
^^^^^^^^^^^^^^^^^^^^^^

Create ``Page`` objects with ``site.get_page(title)``,
``page.toggle_talk()``, ``user.get_userpage()``, or ``user.get_talkpage()``.
They provide the following attributes:

- ``title``: the page's title, or pagename
- ``exists``: whether the page exists
- ``pageid``: an integer ID representing the page
- ``url``: the page's URL
- ``namespace``: the page's namespace as an integer
- ``protection``: the page's current protection status
- ``is_talkpage``: ``True`` if the page is a talkpage, else ``False``
- ``is_redirect``: ``True`` if the page is a redirect, else ``False``

and the following methods:

- ``reload()``: forcibly reload the page's attributes (emphasis on *reload* -
this is only necessary if there is reason to believe they have changed)
- ``toggle_talk(...)``: returns a content page's talk page, or vice versa
- ``get()``: returns page content
- ``get_redirect_target()``: if the page is a redirect, returns its destination
- ``get_creator()``: returns a ``User`` object representing the first user to
edit the page
- ``edit(text, summary, minor=False, bot=True, force=False)``: replaces the
page's content with ``text`` or creates a new page
- ``add_section(text, title, minor=False, bot=True, force=False)``: adds a new
section named ``title`` at the bottom of the page
- ``copyvio_check(...)``: checks the page for copyright violations
- ``copyvio_compare(url, ...)``: checks the page like ``copyvio_check()``, but
against a specific URL

Additionally, ``Category`` objects (created with ``site.get_category(name)`` or
``site.get_page(title)`` where ``title`` is in the ``Category:`` namespace)
provide the following additional method:

- ``get_members(use_sql=False, limit=None)``: returns a list of page titles in
the category (limit is ``50`` by default if using the API)

Users
^^^^^

Create ``User`` objects with ``site.get_user(name)`` or
``page.get_creator()``. They provide the following attributes:

- ``name``: the user's username
- ``exists``: ``True`` if the user exists, or ``False`` if they do not
- ``userid``: an integer ID representing the user
- ``blockinfo``: information about any current blocks on the user (``False`` if
no block, or a dict of ``{"by": blocking_user, "reason": block_reason,
"expiry": block_expire_time}``)
- ``groups``: a list of the user's groups
- ``rights``: a list of the user's rights
- ``editcount``: the number of edits made by the user
- ``registration``: the time the user registered as a ``time.struct_time``
- ``emailable``: ``True`` if you can email the user, ``False`` if you cannot
- ``gender``: the user's gender (``"male"``, ``"female"``, or ``"unknown"``)

and the following methods:

- ``reload()``: forcibly reload the user's attributes (emphasis on *reload* -
this is only necessary if there is reason to believe they have changed)
- ``get_userpage()``: returns a ``Page`` object representing the user's
userpage
- ``get_talkpage()``: returns a ``Page`` object representing the user's
talkpage

Additional features
^^^^^^^^^^^^^^^^^^^

Not all aspects of the toolset are covered here. Explore `its code and
docstrings`_ to learn how to use it in a more hands-on fashion. For reference,
``bot.wiki`` is an instance of ``earwigbot.wiki.SitesDB`` tied to the
``sites.db`` file in the bot's working directory.

Tips
----

- Logging_ is a fantastic way to track the bot's progress
- Logging_ is a fantastic way to monitor the bot's progress as it runs. It has
a slew of built-in loggers, and enabling log retention (so logs are saved to
``logs/`` in the working directory) is highly recommended. In the normal
setup, there are three log files, each of which "rotate" at a specific time
(``filename.log`` becomes ``filename.log.2012-04-10``, for example). The
``debug.log`` file rotates every hour, and maintains six hours of logs of
every level (``DEBUG`` and up). ``bot.log`` rotates every day at midnight,
and maintains seven days of non-debug logs (``INFO`` and up). Finally,
``error.log`` rotates every Sunday night, and maintains four weeks of logs
indicating unexpected events (``WARNING`` and up).

To use logging in your commands or tasks (recommended), ``BaseCommand`` and
``BaseTask`` provide ``logger`` attributes configured for the specific
command or task. If you're working with other classes, ``bot.logger`` is the
root logger (``logging.getLogger("earwigbot")`` by default), so you can use
``getChild`` to make your logger. For example, task loggers are essentially
``bot.logger.getChild("tasks").getChild(task.name)``.

- A very useful IRC command is "``!reload``", which reloads all commands and
tasks without restarting the bot. [3]_ Combined with using the `!git plugin`_
for pulling repositories from IRC, this can provide a seamless command/task
development workflow if the bot runs on an external server and you set up
its working directory as a git repo.

- You can run a task by itself instead of the entire bot with ``earwigbot
path/to/working/dir --task task_name``.

- Questions, comments, or suggestions about the documentation? `Let me know`_
so I can improve it for other people.
