Guide to Regex in Calibre Editor vs Notepad++

[Agama]

I've been using Tweak Book and Notepad++ to edit ePubs from within calibre but the new integrated book editor is a much better option, (great work Kovid!), but I would just like to know whether the flavour of regex used in this editor is the same as in Notepad++ or whether there is an online guide to calibre's editor regex.

I believe the REGEX is the same as Sigil used: PCRE

This post from Manichean got e started:

Not used Sigil, (what's PCRE?), but thanks for Manichean's post. I'll have a play with the regex features that I use in Notepad++ and see what happens in calibre.

"Notepad++ regular expressions use the standard PCRE (Perl) syntax, only departing from it in very minor ways. "

(From the Notepad ++ wiki)

So it should be all but identical.

From the PCRE website:

The PCRE library is a set of functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5

And in case you haven't spotted it - PCRE = PERL Compatible Regular Expression. ( http://en.wikipedia.org/wiki/PCRE )

It helps to remember what it is if you know what the abbreviation stands for.

Thanks for the infos. Looks like a nice easy transition to calibre's new integrated book editor and the preview pane is a real bonus. Feels like an early Christmas present.

BTW, Kovid indicated that calibre uses the regex engine which can be found here https://pypi.python.org/pypi/regex
