wikitextparser 0.6.4

A simple, purely python, WikiText parsing tool.

A simple, purely python, WikiText parsing tool.

The purpose is to allow users easily extract and/or manipulate templates, template parameters, parser functions, tables, external links, wikilinks, etc. in wikitexts.

Installation

Use pip install wikitextparser

Usage

Here is a short demo of some of the functionalities:

>>> import wikitextparser as wtp

WikiTextParser can detect sections, parserfunctions, templates, wikilinks, external links, arguments, tables, and HTML comments in your wikitext:

>>> wt = wtp.parse("""
== h2 ==
t2

=== h3 ===
t3

== h22 ==
t22

{{text|value1{{text|value2}}}}

[[A|B]]""")
>>>
>>> wt.templates
[Template('{{text|value2}}'), Template('{{text|value1{{text|value2}}}}')]
>>> wt.templates[1].arguments
[Argument("|value1{{text|value2}}")]
>>> wt.templates[1].arguments[0].value = 'value3'
>>> print(wt)

== h2 ==
t2

=== h3 ===
t3

== h22 ==
t22

{{text|value3}}

[[A|B]]

It provides easy-to-use properties so you can get or set names or values of templates, arguments, wikilinks, etc.:

>>> wt.wikilinks
[WikiLink("[[A|B]]")]
>>> wt.wikilinks[0].target = 'Z'
>>> wt.wikilinks[0].text = 'X'
>>> wt.wikilinks[0]
WikiLink('[[Z|X]]')
>>>
>>> from pprint import pprint
>>> pprint(wt.sections)
[Section('\n'),
 Section('== h2 ==\nt2\n\n=== h3 ===\nt3\n\n'),
 Section('=== h3 ===\nt3\n\n'),
 Section('== h22 ==\nt22\n\n{{text|value3}}\n\n[[Z|X]]')]
>>>
>>> wt.sections[1].title = 'newtitle'
>>> print(wt)

==newtitle==
t2

=== h3 ===
t3

== h22 ==
t22

{{text|value3}}

[[Z|X]]

There is a pprint function that pretty-prints templates:

>>> p = wtp.parse('{{t1 |b=b|c=c| d={{t2|e=e|f=f}} }}')
>>> t2, t1 = p.templates
>>> print(t2.pprint())
{{t2
    |e=e
    |f=f
}}
>>> print(t1.pprint())
{{t1
    |b=b
    |c=c
    |d={{t2
        |e=e
        |f=f
    }}
}}

If you are dealing with [[Category:Pages using duplicate arguments in template calls]] there are two functions that may be helpful:

>>> t = wtp.Template('{{t|a=a|a=b|a=a}}')
>>> t.rm_dup_args_safe()
>>> t
Template('{{t|a=b|a=a}}')
>>> t = wtp.Template('{{t|a=a|a=b|a=a}}')
>>> t.rm_first_of_dup_args()
>>> t
Template('{{t|a=a}}')

Extracting cell values of a table is easy:

>>> p = wtp.parse("""{|
|  Orange    ||   Apple   ||   more
|-
|   Bread    ||   Pie     ||   more
|-
|   Butter   || Ice cream ||  and more
|}""")
>>> pprint(p.tables[0].getdata)
[['Orange', 'Apple', 'more'],
 ['Bread', 'Pie', 'more'],
 ['Butter', 'Ice cream', 'and more']]

And values are rearranged according to colspan and rowspan attributes (by default):

>>> t = wtp.Table("""{| class="wikitable sortable"
|-
! a !! b !! c
|-
!colspan = "2" | d || e
|-
|}""")
>>> t.getdata(span=True)
[['a', 'b', 'c'], ['d', 'd', 'e']]
