Formats text following the MediaWiki (http://meta.wikimedia.org/wiki/Help:Editing) syntax.

Usage

To return HTML from Wiki:

from wikimarkup import parse

html = parse(text[, show_toc=True])

To return HTML without certain "annoying" (TODO: define annoying) elements, such as headings:

from wikimarkup import parselite

parselite(text)

Adding New Tags

You can add new tags with the registerTagHook method.:

from wikimarkup import registerTagHook, parse
import cgi

def blockquoteTagHook(parser_env, body, attributes={}):
    """<quote[ cite="Person"]>A paragraph of text.</quote>"""
    text = ['<blockquote>']
    if 'cite' in attributes:
        text.append('<cite>%s</cite>' % (cgi.escape(attributes['cite']),))
    text.append(parse(body.strip()))
    text.append('</blockquote>')
    return u'\n'.join(text)
registerTagHook('quote', blockquoteTagHook)

Adding Internal Links

You can support [[internal links]] with the registerInternalLinkHook method. There is no default handling for internal links. If no hook handles the link, it will appear unchanged in the output. An internal link may have a namespace: prefix. Hooks are registered per namespace, with 'None' for unprefixed links:

def internalLinkHook(parser_env, namespace, body):

... return replacement

registerInternalLinkHook(None, internalLinkHook) # called for [[link]] registerInternalLinkHook('Wikipedia', hook) # called for [[Wikipedia: Link]] registerInternalLinkHook(':en', hook) # called for [[:en:link] registerInternalLinkHook(':', hook) # called for [[:any:link]] registerInternalLinkHook('*', hook) # called for [[anything]]

Examples:

from wikimarkup import parse, registerInternalLinkHook

def wikipediaLinkHook(parser_env, namespace, body):

# namespace is going to be 'Wikipedia' (article, pipe, text) = body.partition('|') href = article.strip().capitalize().replace(' ', '_') text = (text or article).strip() return '<a href="http://en.wikipedia.org/wiki/%s">%s</a>' % (href, text)

registerInternalLinkHook('Wikipedia', wikipediaLinkHook)

print parse("[[Wikipedia:public transport|public transportation]]") print parse("[[Wikipedia: bus]]")

import settings from pytils.translit import slugify from blog.models import Post

def byteflowLinkHook(parser_env, namespace, body):

(article, pipe, text) = body.partition('|') slug = slugify(article.strip()) text = (text or article).strip() try:

post = Post.objects.get(slug=slug) href = post.get_absolute_url()

except Post.DoesNotExist:

href = '#'

return '<a href="%s">%s</a>' % (href, text)

registerInternalLinkHook(None, byteflowLinkHook)

parse("[[Blog post title]]")
