Editing Module:Wikitext Parsing/doc (section)

== PrepareText ==
{{Module rating|release}}
<code>PrepareText(text, keepComments)</code> will run any content within certain tags that disable processing ({{tag|nowiki|o}}, {{tag|pre|o}}, {{tag|syntaxhighlight|o}}, {{tag|source|o}}, {{tag|math|o}}) through mw.text.nowiki and remove HTML comments to avoid irrelevant text being processed by modules, allowing tricky syntax to be parsed through more basic means such as <code>%b{}</code>.

If the second parameter, <code>keepComments</code>, is set to true, the content of HTML comments will be passed through mw.text.nowiki instead of being removed entirely.

Any code using this function directly should consider using mw.text.decode to correct the output at the end if part of the processed text is returned, though this will also decode any input that was encoded but not inside a no-processing tag, which likely isn't a significant issue but still something worth considering.
