  1. Changelog
  2. =========
  3. v0.5
  4. ----
  5. Unreleased
  6. (`changes <https://github.com/earwig/mwparserfromhell/compare/v0.4.4...develop>`__):
  7. - Added :meth:`.Wikicode.contains` to determine whether a :class:`.Node` or
  8. :class:`.Wikicode` object is contained within another :class:`.Wikicode`
  9. object.
  10. - Added :meth:`.Wikicode.get_ancestors` and :meth:`.Wikicode.get_parent` to
  11. find all ancestors and the direct parent of a :class:`.Node`, respectively.
  12. - Fixed a long-standing performance issue with deeply nested, invalid syntax
  13. (`issue #42 <https://github.com/earwig/mwparserfromhell/issues/42>`_). The
  14. parser should be much faster on certain complex pages. The "max cycle"
  15. restriction has also been removed, so some situations where templates at the
  16. end of a page were being skipped are now resolved.
  17. - Made :meth:`Template.remove(keep_field=True) <.Template.remove>` behave more
  18. reasonably when the parameter is already empty.
  19. - Added the *keep_template_params* argument to :meth:`.Wikicode.strip_code`.
  20. If *True*, then template parameters will be preserved in the output.
  21. - :class:`.Wikicode` objects can now be pickled properly (fixed infinite
  22. recursion error on incompletely-constructed :class:`.StringMixIn`
  23. subclasses).
  24. - Fixed :meth:`.Wikicode.matches`\ 's behavior on iterables besides lists and
  25. tuples.
  26. - Fixed ``len()`` sometimes raising ``ValueError`` on empty node lists.
  27. - Fixed release script after changes to PyPI.
  28. v0.4.4
  29. ------
  30. `Released December 30, 2016 <https://github.com/earwig/mwparserfromhell/tree/v0.4.4>`_
  31. (`changes <https://github.com/earwig/mwparserfromhell/compare/v0.4.3...v0.4.4>`__):
  32. - Added support for Python 3.6.
  33. - Fixed parsing bugs involving:
  34. - wikitables nested in templates;
  35. - wikitable error recovery when unable to recurse;
  36. - templates nested in template parameters before other parameters.
  37. - Fixed parsing file-like objects.
  38. - Made builds deterministic.
  39. - Documented caveats.
  40. v0.4.3
  41. ------
  42. `Released October 29, 2015 <https://github.com/earwig/mwparserfromhell/tree/v0.4.3>`_
  43. (`changes <https://github.com/earwig/mwparserfromhell/compare/v0.4.2...v0.4.3>`__):
  44. - Added Windows binaries for Python 3.5.
  45. - Fixed edge cases involving wikilinks inside of external links and vice versa.
  46. - Fixed a C tokenizer crash when a keyboard interrupt happens while parsing.
  47. v0.4.2
  48. ------
  49. `Released July 30, 2015 <https://github.com/earwig/mwparserfromhell/tree/v0.4.2>`__
  50. (`changes <https://github.com/earwig/mwparserfromhell/compare/v0.4.1...v0.4.2>`__):
  51. - Fixed setup script not including header files in releases.
  52. - Fixed Windows binary uploads.
  53. v0.4.1
  54. ------
  55. `Released July 30, 2015 <https://github.com/earwig/mwparserfromhell/tree/v0.4.1>`__
  56. (`changes <https://github.com/earwig/mwparserfromhell/compare/v0.4...v0.4.1>`__):
  57. - The process for building Windows binaries has been fixed, and these should be
  58. distributed along with new releases. Windows users can now take advantage of
  59. C speedups without having a compiler of their own.
  60. - Added support for Python 3.5.
  61. - ``<`` and ``>`` are now disallowed in wikilink titles and template names.
  62. This includes when denoting tags, but not comments.
  63. - Fixed the behavior of *preserve_spacing* in :meth:`.Template.add` and
  64. *keep_field* in :meth:`.Template.remove` on parameters with hidden keys.
  65. - Removed :meth:`._ListProxy.detach`. :class:`.SmartList`\ s now use weak
  66. references and their children are garbage-collected properly.
  67. - Fixed parser bugs involving:
  68. - templates with completely blank names;
  69. - templates with newlines and comments.
  70. - Heavy refactoring and fixes to the C tokenizer, including:
  71. - corrected a design flaw in text handling, allowing for substantial speed
  72. improvements when parsing long strings of plain text;
  73. - implemented new Python 3.3
  74. `PEP 393 <https://www.python.org/dev/peps/pep-0393/>`_ Unicode APIs.
  75. - Fixed various bugs in :class:`.SmartList`, including one that was causing
  76. memory issues on 64-bit builds of Python 2 on Windows.
  77. - Fixed some bugs in the release scripts.
  78. v0.4
  79. ----
  80. `Released May 23, 2015 <https://github.com/earwig/mwparserfromhell/tree/v0.4>`_
  81. (`changes <https://github.com/earwig/mwparserfromhell/compare/v0.3.3...v0.4>`__):
  82. - The parser now falls back on pure Python mode if C extensions cannot be
  83. built. This fixes an issue that prevented some Windows users from installing
  84. the parser.
  85. - Added support for parsing wikicode tables (patches by David Winegar).
  86. - Added a script to test for memory leaks in :file:`scripts/memtest.py`.
  87. - Added a script to do releases in :file:`scripts/release.sh`.
  88. - *skip_style_tags* can now be passed to :func:`mwparserfromhell.parse()
  89. <.parse_anything>` (previously, only :meth:`.Parser.parse` allowed it).
  90. - The *recursive* argument to :class:`Wikicode's <.Wikicode>` :meth:`.filter`
  91. methods now accepts a third option, ``RECURSE_OTHERS``, which recurses over
  92. all children except instances of *forcetype* (for example,
  93. ``code.filter_templates(code.RECURSE_OTHERS)`` returns all un-nested
  94. templates).
  95. - The parser now understands HTML tag attributes quoted with single quotes.
  96. When setting a tag attribute's value, quotes will be added if necessary. As
  97. part of this, :class:`.Attribute`\ 's :attr:`~.Attribute.quoted` attribute
  98. has been changed to :attr:`~.Attribute.quotes`, and is now either a string or
  99. ``None``.
  100. - Calling :meth:`.Template.remove` with a :class:`.Parameter` object that is
  101. not part of the template now raises :exc:`ValueError` instead of doing
  102. nothing.
  103. - :class:`.Parameter`\ s with non-integer keys can no longer be created with
  104. *showkey=False*, nor have the value of this attribute be set to *False*
  105. later.
  106. - :meth:`._ListProxy.destroy` has been changed to :meth:`._ListProxy.detach`,
  107. and now works in a more useful way.
  108. - If something goes wrong while parsing, :exc:`.ParserError` will now be
  109. raised. Previously, the parser would produce an unclear :exc:`.BadRoute`
  110. exception or allow an incorrect node tree to be build.
  111. - Fixed parser bugs involving:
  112. - nested tags;
  113. - comments in template names;
  114. - tags inside of ``<nowiki>`` tags.
  115. - Added tests to ensure that parsed trees convert back to wikicode without
  116. unintentional modifications.
  117. - Added support for a :envvar:`NOWEB` environment variable, which disables a
  118. unit test that makes a web call.
  119. - Test coverage has been improved, and some minor related bugs have been fixed.
  120. - Updated and fixed some documentation.
  121. v0.3.3
  122. ------
  123. `Released April 22, 2014 <https://github.com/earwig/mwparserfromhell/tree/v0.3.3>`_
  124. (`changes <https://github.com/earwig/mwparserfromhell/compare/v0.3.2...v0.3.3>`__):
  125. - Added support for Python 2.6 and 3.4.
  126. - :meth:`.Template.has` is now passed *ignore_empty=False* by default
  127. instead of *True*. This fixes a bug when adding parameters to templates with
  128. empty fields, **and is a breaking change if you rely on the default
  129. behavior.**
  130. - The *matches* argument of :class:`Wikicode's <.Wikicode>` :meth:`.filter`
  131. methods now accepts a function (taking one argument, a :class:`.Node`, and
  132. returning a bool) in addition to a regex.
  133. - Re-added *flat* argument to :meth:`.Wikicode.get_sections`, fixed the order
  134. in which it returns sections, and made it faster.
  135. - :meth:`.Wikicode.matches` now accepts a tuple or list of
  136. strings/:class:`.Wikicode` objects instead of just a single string or
  137. :class:`.Wikicode`.
  138. - Given the frequency of issues with the (admittedly insufficient) tag parser,
  139. there's a temporary *skip_style_tags* argument to :meth:`~.Parser.parse` that
  140. ignores ``''`` and ``'''`` until these issues are corrected.
  141. - Fixed a parser bug involving nested wikilinks and external links.
  142. - C code cleanup and speed improvements.
  143. v0.3.2
  144. ------
  145. `Released September 1, 2013 <https://github.com/earwig/mwparserfromhell/tree/v0.3.2>`_
  146. (`changes <https://github.com/earwig/mwparserfromhell/compare/v0.3.1...v0.3.2>`__):
  147. - Added support for Python 3.2 (along with current support for 3.3 and 2.7).
  148. - Renamed :meth:`.Template.remove`\ 's first argument from *name* to *param*,
  149. which now accepts :class:`.Parameter` objects in addition to parameter name
  150. strings.
  151. v0.3.1
  152. ------
  153. `Released August 29, 2013 <https://github.com/earwig/mwparserfromhell/tree/v0.3.1>`_
  154. (`changes <https://github.com/earwig/mwparserfromhell/compare/v0.3...v0.3.1>`__):
  155. - Fixed a parser bug involving URLs nested inside other markup.
  156. - Fixed some typos.
  157. v0.3
  158. ----
  159. `Released August 24, 2013 <https://github.com/earwig/mwparserfromhell/tree/v0.3>`_
  160. (`changes <https://github.com/earwig/mwparserfromhell/compare/v0.2...v0.3>`__):
  161. - Added complete support for HTML :class:`Tags <.Tag>`, including forms like
  162. ``<ref>foo</ref>``, ``<ref name="bar"/>``, and wiki-markup tags like bold
  163. (``'''``), italics (``''``), and lists (``*``, ``#``, ``;`` and ``:``).
  164. - Added support for :class:`.ExternalLink`\ s (``http://example.com/`` and
  165. ``[http://example.com/ Example]``).
  166. - :class:`Wikicode's <.Wikicode>` :meth:`.filter` methods are now passed
  167. *recursive=True* by default instead of *False*. **This is a breaking change
  168. if you rely on any filter() methods being non-recursive by default.**
  169. - Added a :meth:`.matches` method to :class:`.Wikicode` for page/template name
  170. comparisons.
  171. - The *obj* param of :meth:`.Wikicode.insert_before`, :meth:`.insert_after`,
  172. :meth:`~.Wikicode.replace`, and :meth:`~.Wikicode.remove` now accepts
  173. :class:`.Wikicode` objects and strings representing parts of wikitext,
  174. instead of just nodes. These methods also make all possible substitutions
  175. instead of just one.
  176. - Renamed :meth:`.Template.has_param` to :meth:`~.Template.has` for consistency
  177. with :class:`.Template`\ 's other methods; :meth:`.has_param` is now an
  178. alias.
  179. - The C tokenizer extension now works on Python 3 in addition to Python 2.7.
  180. - Various bugfixes, internal changes, and cleanup.
  181. v0.2
  182. ----
  183. `Released June 20, 2013 <https://github.com/earwig/mwparserfromhell/tree/v0.2>`_
  184. (`changes <https://github.com/earwig/mwparserfromhell/compare/v0.1.1...v0.2>`__):
  185. - The parser now fully supports Python 3 in addition to Python 2.7.
  186. - Added a C tokenizer extension that is significantly faster than its Python
  187. equivalent. It is enabled by default (if available) and can be toggled by
  188. setting :attr:`mwparserfromhell.parser.use_c` to a boolean value.
  189. - Added a complete set of unit tests covering parsing and wikicode
  190. manipulation.
  191. - Renamed :meth:`.filter_links` to :meth:`.filter_wikilinks` (applies to
  192. :meth:`.ifilter` as well).
  193. - Added filter methods for :class:`Arguments <.Argument>`,
  194. :class:`Comments <.Comment>`, :class:`Headings <.Heading>`, and
  195. :class:`HTMLEntities <.HTMLEntity>`.
  196. - Added *before* param to :meth:`.Template.add`; renamed *force_nonconformity*
  197. to *preserve_spacing*.
  198. - Added *include_lead* param to :meth:`.Wikicode.get_sections`.
  199. - Removed *flat* param from :meth:`.get_sections`.
  200. - Removed *force_no_field* param from :meth:`.Template.remove`.
  201. - Added support for Travis CI.
  202. - Added note about Windows build issue in the README.
  203. - The tokenizer will limit itself to a realistic recursion depth to prevent
  204. errors and unreasonably long parse times.
  205. - Fixed how some nodes' attribute setters handle input.
  206. - Fixed multiple bugs in the tokenizer's handling of invalid markup.
  207. - Fixed bugs in the implementation of :class:`.SmartList` and
  208. :class:`.StringMixIn`.
  209. - Fixed some broken example code in the README; other copyedits.
  210. - Other bugfixes and code cleanup.
