+This files describes mwclient-0.6.5. The latest version is available in the
+subversion repository <https://mwclient.svn.sourceforge.net/svnroot/mwclient>
+and also browsable <http://mwclient.svn.sourceforge.net/viewvc/mwclient/>.
+
+Mwclient is a client to the MediaWiki API <http://mediawiki.org/wiki/API>
+and allows access to almost all implemented API functions. Mwclient requires
+Python 2.4. This version supports MediaWiki 1.11 and above. However, for
+functions not available in the current MediaWiki, a MediaWikiVersionError
+is raised.
+
+This framework is written by Bryan Tong Minh and serves most of his bots.
+The framework and this documentation are primarily written for personal
+use and may or may not work for you. In case it doesn't, Bryan can be
+contacted on btongminh@users.sourceforge.net.
+
+This framework heavily depends on simplejson, (c) copyright Bob Ippolito.
+
+
+== Implementation notes ==
+Most properties and generators accept the same parameters as the API, without
+their two letter prefix. Exceptions to this rule:
+* Image.imageinfo is the imageinfo of the latest image. Earlier versions can be
+ fetched using imagehistory()
+* Site.all* : parameter [ap]from renamed to start
+* categorymembers is implemented as Category.members
+* deletedrevs is deletedrevisions
+* usercontribs is usercontributions
+* First parameters of search and usercontributions are search and user
+ respectively
+
+Properties and generators are implemented as Python generators. Their limit
+parameter is only an indication of the number of items in one chunk. It is not
+the total limit. Doing list(generator(limit = limit)) will return ALL items of
+generator, and not be limited by the limit value.
+Default chunk size is generally the maximum chunk size.
+
+== HTTPS ==
+To use https, specify the host as a tuple in the form of ('https', hostname).
+
+== Example ==
+## For more information, see REFERENCE.txt
+# Init site object
+import mwclient
+site = mwclient.Site('commons.wikimedia.org')
+site.login(username, password) # Optional
+
+# Edit page
+page = site.Pages['Commons:Sandbox']
+text = page.edit()
+print 'Text in sandbox:', text.encode('utf-8')
+page.save(text + u'\nExtra data', summary = 'Test edit')
+
+# Printing imageusage
+image = site.Images['Example.jpg']
+print 'Image', image.name.encode('utf-8'), 'usage:'
+for page in image.imageusage():
+ print 'Used:', page.name.encode('utf-8'), '; namespace', page.namespace
+ print 'Image info:', image.imageinfo
+
+# Uploading a file
+site.upload(open('file.jpg'), 'destination.jpg', 'Image description')
+
+# Listing all categories (don't do this in reality)
+for category in site.allcategories():
+ print category

+This file is intended to be a reference to mwclient. The current version is
+mwclient 0.6.6.
+
+The mwclient framework provides an access to the MediaWiki API. It provides the
+functions of the MediaWiki API in a Pythonic manner.
+
+== Sites ==
+The 'Site' object is the most important class. It represents a MediaWiki site.
+Its constructor accepts various arguments, of which the first two, host and
+path are the most important. They represent respectively the hostname without
+protocol and the root directory where api.php is located. The path parameter
+should end with a slash /. Other protocols than HTTP are currently not
+supported.
+
+site = mwclient.Site(host, path = '/w/', ...)
+
+=== Pages ===
+Sites provide access to pages via various generators and the Pages object. The
+base Page object is called Page and from that derive Category and Image. When
+the page is retrieved via Site.Pages or a generator, it will check
+automatically which of those three specific types should be returned. To get
+a page by its name, call Site.Pages as a scriptable object:
+
+page = site.Pages['Template:Stub']
+image = site.Pages['Image:Wiki.png'] # This will return an Image object
+image2 = site.Images['Wiki.png'] # The same image
+
+Alternatively Site.Images and Site.Categories are provided, which do exactly
+the same as Site.Pages, except that they require the page name without its
+namespace prefixed.
+
+==== PageProperties ====
+The Page object provides many generators available in the API. In addition to
+the page properties listed in the API documentation, also the lists backlinks
+and embeddedin are members of the Page object. See for more information about
+using generators the section about generators below.
+
+Category objects provide an extra property members to list all members of the
+category. The Category object can also be used itself as an iterator yielding
+all its members.
+
+category = site.Pages['Category:Help']
+for page in category:
+ print category
+
+Image objects have additional functions imagehistory and imageusage which
+represent the old images and the usage respectively. Image.download returns a
+file object to the full size image.
+
+fr = image.download()
+fw = open('Wiki.png', 'rb')
+while True:
+ s = fr.read(4096)
+ if not s: break
+ fw.write(s)
+fr.close() # Always close those file objects !!!
+fw.close()
+
+==== Editting pages ====
+Call Page.edit() to retrieve the page content. Use Page.save(text, summary =
+u'', ...) to save the page. If available, Page.save uses the API to edit, but
+falls back to the old way if the write API is not available.
+
+== Generators ==
+== Exceptions ==
+
+== Implementation notes ==
+Most properties and generators accept the same parameters as the API, without
+their two letter prefix Exceptions:
+* Image.imageinfo is the imageinfo of the latest image. Earlier versions can be
+ fetched using imagehistory()
+* Site.all* : parameter (ap)from renamed to start
+* categorymembers is implemented as Category.members
+* deletedrevs is deletedrevisions
+* usercontribs is usercontributions
+* First parameters of search and usercontributions are search and user
+ respectively
+
+Properties and generators are implemented as Python generators. Their limit
+parameter is only an indication of the number of items in one chunk. It is not
+the total limit. Doing list(generator(limit = limit)) will return ALL items of
+generator, and not be limitted by the limit value. Use list(generator(
+max_items = max_items)) to limit the amount of items returned.
+Default chunk size is generally the maximum chunk size.

+
+This is mwclient 0.6.6. The following are the release notes for this version.
+
+== Changes in version 0.6.6 ==
+No changes yet.
+
+== Changes in version 0.6.5 ==

+* Handle readapidenied error in site init
+* Fix version parsing for almost any sane version string
+
+== Changes in version 0.6.4 ==
+* Added support for upload API
+* Added prop=duplicatefiles
+* Properly fix detection of alpha versions
+* Added support for builtin json library
+* Handle badtoken once
+* Bug 2690034: Fix revision iteration
+* Fix module conflict with simplejson-1.x by inserting mwclient path at the
+ beginning of sys.path instead of the end
+* Supply token on login if necessary
+
+== Changes in version 0.6.3 ==
+* Added domain parameter to login.
+* Applied edit fix to page_nowriteapi
+* Allow arbitrary data to be passed to page.save
+* Fix mwclient on WMF wikis
+
+== Changes in version 0.6.2 ==
+Mwclient was released on 2 May 2009.
+* Compatibility fixes for MediaWiki 1.13
+* Download fix for images
+* Full support for editing pages via write api and split of compatibility to
+ another file.
+* Added expandtemplates api call
+* Added and fixed moving via API
+* Raise an ApiDisabledError is the API is disabled
+* Added support for HTTPS
+* Fixed email code
+* Mark edits as bots by default.
+* Added action=parse. Modified patch by Brian Mingus.
+* Improved general HTTP and upload handling.
+
+== Changes in version 0.6.1 and 0.6.0 ==
+Mwclient 0.6.1 was released in May 2008. No release notes were kept for
+that version.
+
+Mwclient 0.6.0 was released in February 2008. It was the first official
+release via Sourceforge. This version removed some Pywikipedia influences
+added in 0.4.
+
+== Mwclient 0.5 ==
+Mwclient 0.5 was an architectural redesign which accomplished easy
+extendibility and added proper support for continuations.
+
+== Mwclient 0.4 ==
+Mwclient 0.4 was somewhat the basis for future releases and shows the current
+module architecture. It was influenced by Pywikipedia that was by then
+discovered by the author.
+
+== Mwclient 0.2 and 0.3 ==
+Mwclient 0.2 and 0.3 were probably a bit of a generalization, and maybe
+already used the API for some part, but details are unknown.
+
+== Mwclient 0.1 ==
+Mwclient 0.1 was a non-API module for accessing Wikipedia using an XML parser.

+r"""JSON (JavaScript Object Notation) <http://json.org> is a subset of
+JavaScript syntax (ECMA-262 3rd edition) used as a lightweight data
+interchange format.
+
+:mod:`simplejson` exposes an API familiar to users of the standard library
+:mod:`marshal` and :mod:`pickle` modules. It is the externally maintained
+version of the :mod:`json` library contained in Python 2.6, but maintains
+compatibility with Python 2.4 and Python 2.5 and (currently) has
+significant performance advantages, even without using the optional C
+extension for speedups.
+
+Encoding basic Python object hierarchies::
+
+ >>> import simplejson as json
+ >>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
+ '["foo", {"bar": ["baz", null, 1.0, 2]}]'
+ >>> print json.dumps("\"foo\bar")
+ "\"foo\bar"
+ >>> print json.dumps(u'\u1234')
+ "\u1234"
+ >>> print json.dumps('\\')
+ "\\"
+ >>> print json.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True)
+ {"a": 0, "b": 0, "c": 0}
+ >>> from StringIO import StringIO
+ >>> io = StringIO()
+ >>> json.dump(['streaming API'], io)
+ >>> io.getvalue()
+ '["streaming API"]'
+
+Compact encoding::
+
+ >>> import simplejson as json
+ >>> json.dumps([1,2,3,{'4': 5, '6': 7}], separators=(',',':'))
+ '[1,2,3,{"4":5,"6":7}]'
+
+Pretty printing::
+
+ >>> import simplejson as json
+ >>> s = json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=' ')
+ >>> print '\n'.join([l.rstrip() for l in s.splitlines()])
+ {
+ "4": 5,
+ "6": 7
+ }
+
+Decoding JSON::
+
+ >>> import simplejson as json
+ >>> obj = [u'foo', {u'bar': [u'baz', None, 1.0, 2]}]
+ >>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]') == obj
+ True
+ >>> json.loads('"\\"foo\\bar"') == u'"foo\x08ar'
+ True
+ >>> from StringIO import StringIO
+ >>> io = StringIO('["streaming API"]')
+ >>> json.load(io)[0] == 'streaming API'
+ True
+
+Specializing JSON object decoding::
+
+ >>> import simplejson as json
+ >>> def as_complex(dct):
+ ... if '__complex__' in dct:
+ ... return complex(dct['real'], dct['imag'])
+ ... return dct
+ ...
+ >>> json.loads('{"__complex__": true, "real": 1, "imag": 2}',
+ ... object_hook=as_complex)
+ (1+2j)
+ >>> from decimal import Decimal
+ >>> json.loads('1.1', parse_float=Decimal) == Decimal('1.1')
+ True
+
+Specializing JSON object encoding::
+
+ >>> import simplejson as json
+ >>> def encode_complex(obj):
+ ... if isinstance(obj, complex):
+ ... return [obj.real, obj.imag]
+ ... raise TypeError(repr(o) + " is not JSON serializable")
+ ...
+ >>> json.dumps(2 + 1j, default=encode_complex)
+ '[2.0, 1.0]'
+ >>> json.JSONEncoder(default=encode_complex).encode(2 + 1j)
+ '[2.0, 1.0]'
+ >>> ''.join(json.JSONEncoder(default=encode_complex).iterencode(2 + 1j))
+ '[2.0, 1.0]'
+
+
+Using simplejson.tool from the shell to validate and pretty-print::
+
+ $ echo '{"json":"obj"}' | python -m simplejson.tool
+ {
+ "json": "obj"
+ }
+ $ echo '{ 1.2:3.4}' | python -m simplejson.tool
+ Expecting property name: line 1 column 2 (char 2)
