WikiSyntaxTextMod → Syntax polishing → Step 5

Protecting regions

The fifth step protects further areas (after nowiki, codes, and link targets etc.) against general modifications.

This is not always necessary and will be executed only if there is a reason.

Within protected areas nothing is searched, so nothing found or even worse: replaced.

Necessity of protection

There are two levels:

1. Hide from further analysis
   Comments, nowiki and syntaxhighlight
   These regions influence further interpretation and processing of wikitext.
2. Protection against user defined modifications and some changes triggered internally.

In the first case the referred ranges are always protected, while parts deserve to be protected only if later acivity has been scheduled.

Protection of sections with coded information

Ranges with coded information are to be skipped.

Sequence and identification of protected ranges

Begin	Content	End
<!-- <hiddentext>	Comment	--> </hiddentext>
<nowiki>	No wiki formatting	</nowiki>
<syntaxhighlight…> <source…>	syntaxhighlight	</syntaxhighlight> </source>
<hiero> <imagemap> <inputbox> <math> <poem> <pre> <timeline>	hieroglyphs link sensitive images input fields math poem preformatted time line	</hiero> </imagemap> </inputbox> </math> </pre> </timeline>
space at beginning of line	preformatted text	line end (last line in block)
<code>	code	</code>
<tt>	type writer (monospace)	</tt>
<dfn> <kbd> <samp>	code	</dfn> </kbd> </samp>

If in doubt the extension is spread in conservating direction; may be wider than actually intended. If end marks have not been found, since illegal nesting happened in source text, the range is extended at maximum, in extreme cases until end of the entire wikitext.

Keys for sorting of categories and the entire DEFAULTSORT are always protected against user defined modifications.

Since the processing order brings tags into standardised form first and consecutively protected regions are built from those tags, it is possible to show scaring examples for bad formatting of wikisyntax or similar ML only by < or enclosing by <syntaxhighlight>.

Protection of link targets

It is reasonable to modify changed URL and wikilinks of moved pages or disambiguation pages. In particular cases it is meaningful to modify link targets which have been protected before. However, these link targets have to be protected against spelling correction and typographic refinement.

Identification of link target ranges

Begin	Content	End
after [[	wikilink (internal / external) including [[File: (link target only)	before | or before ] or end of line
after[ at [// [http:// [https:// [ftp://	URL	before ] or before space or end of line
http:// https:// ftp://		one of < | > or space or end of line
end of line or space before File: or file name	within <gallery…>	| or end of line
after {{	template name	last non-space before | or }} or end of line
first character of parameter after =	media ID in template	last character of file extension before | or }}

Syntax elements of template transclusion (parameter names with | and =) might be protected as well, but not the parameter values.
