Creating a wiki format with Flexifilter

Flexifilter currently ships with a wiki format, but let's step through it so you can understand how it works.

1. Go to the flexifilter administration area by clicking Administer -> Site Building -> Flexifilters, and click 'Add new flexifilter'.
2. Set the label to 'Wiki'.
3. Set the description to 'A flexifilter for a wiki'.
4. Prepend with </nowiki>.
5. Append with <nowiki>
6. Do a chunk grab on </nowiki> and <nowiki>.
7. Add several pattern-based text replace components:
8. Replace ''' (three single dashes) with alternating <strong> and </strong>.
9. Replace '' (two single dashes) with alternating <em> and </em>.
10. Replace ==== (four equals signs) with alternating <h4> and </h4>
11. Replace === (three equals signs) with alternating <h3> and </h3>
12. Replace == (two equals signs) with alternating <h2> and </h2>
13. Create a chunk grabber on [[ and ]].
14. Add an IF component within the chunk grabber.
15. Add the condition "text contains" with the parameter |.
16. As subcomponents of this IF statement, prepend with <a href="/drupalwikipath/
17. String replace | with ">.
18. Append </a>.
19. Now, outside the if statement, create an IF NOT statement with the same condition.
20. String replace ~ with \~ (escape the character).
21. Append ~~.
22. Add an advanced append. Step 20 should be added to this component.
23. String replace ~~ with </a>.
24. Now, outside of the advanced append, prepend with <a href="/drupalwikipath/
25. String replace ~~ with ">
26. String replace \~ with ~.
