Expansion engine for MediaWiki wiki pages based on mwparserfromhell
Project description
wikiexpand
Expansion engine for pages written using MediaWiki syntax, based on mwparserfromhell.
Wikiexpand tries to mimic the expansion of transcluded text (templates) and magic words (parser functions and variables).
Usage
First, we need to create an expansion context (wikiexpand.expand.ExpansionContext), and provide a place where to look for our templates (wikiexpand.expand.templates.TemplateStore):
# expansion context
from wikiexpand.expand import ExpansionContext
# a template store using `dict` as storage
from wikiexpand.expand.templates import TemplateDict
tpl = TemplateDict()
# define a simple template
tpl["helloworld"] = "Hello World"
# create the expansion context
ctx = ExpansionContext(templates=tpl)
# expand text transcluding our template
ctx.expand("Lorem {{helloworld}}! Ipsum")
'Lorem Hello World! Ipsum'Parser functions and magic words
Most common used parser functions and magic words can also be expanded:
# expand text using a parser functions
ctx.expand("{{#if:x|1|0}} {{#if:|1|0}}")
'1 0'Many magic words provide contextual data which are defined for a site (namespaces, server time, etc.) or a given page (title, url, etc.). In order to be able to expand those magic words, providing site (wikiexpand.expand.context.SiteContext) and page context (wikiexpand.expand.context.PageContext) is required.
# implementation using pywikibot to retrieve info from a Wikimedia site
import pywikibot as pw
from wikiexpand.wiki.context import Wiki
# site context for es.wiktionary.org
eswikt = Wiki(pw.Site("es", "wiktionary"))
# set page context for a page named "hello"
ctx.set_context(eswikt.page_context("hello"))
ctx.expand("Using page context: {{PAGENAME}}, {{TALKSPACE}}. Using site context: [{{fullurl:hello}}], {{NAMESPACE:Template:helloworld}}")

Lua modules
Modules written in Lua and executed using {{#invoke:}} are not recognised, but can be replaced by implementing callable templates (that is, functions that render Wikicode). See the doc in wikiexpand.expand.templates.TemplateStore.callable_templates.
