RegexCase Changing

GregTheGrate · 12-03-2014, 12:47 AM

There are a number of times where a scanned book (out of copyright of course) has the first character of a sentence in lower case. I would like to change these to upper.

I understand that \U and \L are not supported in the Regex engine used in the Calibre editor.

Is there any other way to change case in a Regex replace statement in the Calibre editor?

Yes, using the just-created function mode.

A little overkill, in simple cases like this, but the regex engine calibre uses doesn't support those switches.

http://manual.calibre-ebook.com/function_mode.html

There are builtin functios for titlecasing, capitalizing, uppercasing and lowercasing. That should work here, although arbitrary case-changing would require a function.

Thank you. I hadn't gone there yet - scared - but it proved to be very simple
