Paste this code below into file: models/plugin_wiki_extra.py
class PluginWikiWidgets(PluginWikiWidgets):
@staticmethod
def encode_text(text='',mailto=''):
"""
Purpose: To foil most superficial harvesters
Input: any text
Output: the text encoded as either a decimal or hex entity,
optionally with a mailto link
widget inspired from python implementation of Markdown (MIT license)
"""
def _xml_encode_text_char_at_random(ch):
from random import random
r = random()
# Roughly 20% raw, 40% hex, 40% dec.
# '@' and '_' are always encoded.
if r > 0.8 and ch not in "@_":
return ch
elif r < 0.4:
# [1:] drops leading '0': 0x63 -> x63
return '&#%s;' % hex(ord(ch))[1:]
else:
return '&#%s;' % ord(ch)
def _encode_text(text,mailto):
if mailto.lower()=='true':
chars = [_xml_encode_text_char_at_random(ch)
for ch in "mailto:" + text]
# make link and strip mailto: from the visible email address
text = '<a href="%s">%s</a>' \
% (''.join(chars),
''.join(chars[7:]))
else:
chars = [_xml_encode_text_char_at_random(ch)
for ch in text]
text = ''.join(chars)
return text
return _encode_text(text, mailto)
Now in your wiki page enter something like these following examples:
Example 1 - Text
`` name:encode_text text:My private telephone number 01 234567 ``:widget
Example 2 - Email Address
`` name:encode_text text:foo@bar.com mailto:true ``:widget
If you look at the HTML source produced, you will see something like the text below, which isn't very nice for the average bot to parse::
My private telephone number: 01 234567
Note that apart from the text, there is just one other optional parameter mailto:true which makes an email address into a mailto: link.
Hope you find it useful or interesting as a simple example of adding an extra plugin_wiki widget.
