  1. mwparserfromhell
  2. ================
  3. **mwparserfromhell** (the *MediaWiki Parser from Hell*) is a Python package
  4. that provides an easy-to-use and outrageously powerful parser for MediaWiki_
  5. wikicode. It supports Python 2 and Python 3.
  6. Developed by Earwig_ with help from `Σ`_.
  7. Installation
  8. ------------
  9. The easiest way to install the parser is through the `Python Package Index`_,
  10. so you can install the latest release with ``pip install mwparserfromhell``
  11. (`get pip`_). Alternatively, get the latest development version::
  12. git clone git://github.com/earwig/mwparserfromhell.git
  13. cd mwparserfromhell
  14. python setup.py install
  15. You can run the comprehensive unit testing suite with
  16. ``python setup.py test -q``.
  17. Usage
  18. -----
  19. Normal usage is rather straightforward (where ``text`` is page text)::
  20. >>> import mwparserfromhell
  21. >>> wikicode = mwparserfromhell.parse(text)
  22. ``wikicode`` is a ``mwparserfromhell.Wikicode`` object, which acts like an
  23. ordinary ``unicode`` object (or ``str`` in Python 3) with some extra methods.
  24. For example::
  25. >>> text = "I has a template! {{foo|bar|baz|eggs=spam}} See it?"
  26. >>> wikicode = mwparserfromhell.parse(text)
  27. >>> print wikicode
  28. I has a template! {{foo|bar|baz|eggs=spam}} See it?
  29. >>> templates = wikicode.filter_templates()
  30. >>> print templates
  31. ['{{foo|bar|baz|eggs=spam}}']
  32. >>> template = templates[0]
  33. >>> print template.name
  34. foo
  35. >>> print template.params
  36. ['bar', 'baz', 'eggs=spam']
  37. >>> print template.get(1).value
  38. bar
  39. >>> print template.get("eggs").value
  40. spam
  41. Since every node you reach is also a ``Wikicode`` object, it's trivial to get
  42. nested templates::
  43. >>> code = mwparserfromhell.parse("{{foo|this {{includes a|template}}}}")
  44. >>> print code.filter_templates()
  45. ['{{foo|this {{includes a|template}}}}']
  46. >>> foo = code.filter_templates()[0]
  47. >>> print foo.get(1).value
  48. this {{includes a|template}}
  49. >>> print foo.get(1).value.filter_templates()[0]
  50. {{includes a|template}}
  51. >>> print foo.get(1).value.filter_templates()[0].get(1).value
  52. template
  53. Additionally, you can include nested templates in ``filter_templates()`` by
  54. passing ``recursive=True``::
  55. >>> text = "{{foo|{{bar}}={{baz|{{spam}}}}}}"
  56. >>> mwparserfromhell.parse(text).filter_templates(recursive=True)
  57. ['{{foo|{{bar}}={{baz|{{spam}}}}}}', '{{bar}}', '{{baz|{{spam}}}}', '{{spam}}']
  58. Templates can be easily modified to add, remove, or alter params. ``Wikicode``
  59. can also be treated like a list with ``append()``, ``insert()``, ``remove()``,
  60. ``replace()``, and more::
  61. >>> text = "{{cleanup}} '''Foo''' is a [[bar]]. {{uncategorized}}"
  62. >>> code = mwparserfromhell.parse(text)
  63. >>> for template in code.filter_templates():
  64. ... if template.name == "cleanup" and not template.has_param("date"):
  65. ... template.add("date", "July 2012")
  66. ...
  67. >>> print code
  68. {{cleanup|date=July 2012}} '''Foo''' is a [[bar]]. {{uncategorized}}
  69. >>> code.replace("{{uncategorized}}", "{{bar-stub}}")
  70. >>> print code
  71. {{cleanup|date=July 2012}} '''Foo''' is a [[bar]]. {{bar-stub}}
  72. >>> print code.filter_templates()
  73. ['{{cleanup|date=July 2012}}', '{{bar-stub}}']
  74. You can then convert ``code`` back into a regular ``unicode`` object (for
  75. saving the page!) by calling ``unicode()`` on it::
  76. >>> text = unicode(code)
  77. >>> print text
  78. {{cleanup|date=July 2012}} '''Foo''' is a [[bar]]. {{bar-stub}}
  79. >>> text == code
  80. True
  81. Likewise, use ``str(code)`` in Python 3.
  82. Integration
  83. -----------
  84. ``mwparserfromhell`` is used by and originally developed for EarwigBot_;
  85. ``Page`` objects have a ``parse`` method that essentially calls
  86. ``mwparserfromhell.parse()`` on ``page.get()``.
  87. If you're using Pywikipedia_, your code might look like this::
  88. import mwparserfromhell
  89. import wikipedia as pywikibot
  90. def parse(title):
  91. site = pywikibot.getSite()
  92. page = pywikibot.Page(site, title)
  93. text = page.get()
  94. return mwparserfromhell.parse(text)
  95. If you're not using a library, you can parse templates in any page using the
  96. following code (via the API_)::
  97. import json
  98. import urllib
  99. import mwparserfromhell
  100. API_URL = "http://en.wikipedia.org/w/api.php"
  101. def parse(title):
  102. data = {"action": "query", "prop": "revisions", "rvlimit": 1,
  103. "rvprop": "content", "format": "json", "titles": title}
  104. raw = urllib.urlopen(API_URL, urllib.urlencode(data)).read()
  105. res = json.loads(raw)
  106. text = res["query"]["pages"].values()[0]["revisions"][0]["*"]
  107. return mwparserfromhell.parse(text)
