re.place is a module wich acts as a content filter. It searches for pre-defined 
regular expressions and replaces matches with pre-defined replacements.
It is possible to specify different replacements based on several 
“replacement restrictions” — for authenticated users and guests, 
for pages and non-pages currently (see “Screenshots”).
For example, you can implement the functionality of cross-linker module, while 
adding the possibility to insert “target” parameter, “rel=nofollow”, style 
information, etc.
As another example, you can insert in your posts custom smiles or the like.
As another example, you can add custom markup to you blog, like 
 Google(something) would insert link to <code>www.google.com/search?q=something</code>, 
 TouTube(youtube_id) will insert <code><object ...></code>, wich displays that video, 
etc-etc. See “Other notes” for more examples.
You can replace http links with some other stuff for guests, leaving as is for 
authenticated users (see https://wordpress.org/support/topic/297405).
Every entry can have custom “order” number, so you can chain your replacements.
re.place stores entries in database.
Management GUI provided to list entries, add, edit or delete entries.
See changelog for some changes tracking.
<h3>A brief examples</h3>
<ol>
<li>
As a search field, use ‘<code>_—</code>‘ (space in place of <code>_</code>!), 
as a replace — ‘<code>#160;—</code>‘. This will insert non-breaking space 
before every em-dash.
Mmm… You may wish even use ‘<code><span 
style="letter-spacing:0.1ex;">#160;—</code>‘ as a replase to insert 
narrower non-breaking space… If you love typography too much… And you 
can make space after dot wider…
</li>
<li>
Search for ‘<code>:-)</code>‘ and replace with:
‘<code><img src="http://www.kolobok.us/smiles/standart/smile3.gif"' . 
 'alt=":-)" title=":-) (nice smile -- http://www.kolobok.us/smiles/standart/smile3.gif)"' . 
 'style="vertical-align: middle;" /></code>‘
</li>
<li>
Search pattern: <code>YouTube\(([a-zA-Z_0-9\-]*)\)</code>
Replace pattern:
‘<code><object width="425" height="344" data="http://www.youtube.com/v/\1" type="application/x-shockwave-flash"> 
 <param name="movie" value="http://www.youtube.com/v/\1"></param> 
</object></code>‘
This will allow you to use markups like <code>YouTube(TMCf7SNUb-Q)</code> to insert 
Youtube video fragments easily.

How to Mass Remove Link (mass deactivate URL Linked text inside posts)? 
(https://wordpress.org/support/topic/288020)
Search pattern: <code><a [^>]*>([^<]*)<\/a></code>
Replace pattern: <code>\1</code>
This will “deactivate” all links in all posts 
(e.g. replace <code><a href="...">Try!</a></code> with just <code>Try!</code>). 
Note, you can activate them back, deactivating this <code>re.place</code> entry.
</li>
<li>
Want to insert drop caps easily?.. Use ‘<code><drop>L</drop>orem ipsum...</code>‘ in your 
posts and replace it with <code>\1</code>‘. Use angle brackets, 
and if you (accidentally) deactivate re.place, these “tags” won’t mess you page.
</li>
<li>
New — in v0.1.3 — [beta-] feature: you can specify different replace patterns 
for authenticated users and “guests”. Sorry, i’ll update screenshots and doc 
ASAP. 🙂
