I'm a relative newcomer to NPP and, although I've adapted NPP as my default text processor, I find the status of regular expression editing confusing. So my question is, What's the skinny on regular expressions?

What does NPP have in the way of regular expressions, and what is in them. It's clear that they do not meet 'standards' for regular expressions, not that I'm expert.

I'm happy to summarise the status of REs but I need access to information.

I've used REs in both normal search-and-replace mode (Ctrl/H) and advanced search-and-replace mode (Ctrl/R). Neither are the full quid. The documentation for normal (or what some people call simple) search-and-replace (http://notepad-plus.sourceforge.net/uk/regExpList.php ) is incomplete. For example, it doesn't say what can be used in replacement strings.  (Not much from what I've seen, unless I'm not doing it right.)

As for advanced search-and-replace, I haven't been able to find any documentation.

I've skimmed the messages in Help and Open Discussion and I would summarise them as follows:

  * messages about the deficiencies in REs
  * pleas for replacement of Scintilla for REs by something else
  * requests and solutions for things that do not appear possible in REs but should be
  * reasons why somethings are not possible in REs in NPP

Pointers to information releveant to REs in NPP will be much appreciated
