search and replace - drops blanks in replace ?

i tried using S&R in epub to epub conversion to replace all mdash with space ndash space.

it seems that the replace function drops the leading & training spaces so what it actually does is to replace all mdash with ndash - not what I wanted ???

i then tried escaping the space characters but got failed conversion with that approach

that is self defeating, I want to make the change so that lines can be split on either side of the ndash ( once converted to Kindle) if needs be - a non breaking space either side would prevent that I assume.

other search / replace engines ( e.g. sigil) support leading / trailing spaces - they are somewhat essential when using regex to remove unwanted line feeds. as you need constructs like space\1 in your replace box.

it would be MUCH faster to do a single find+replace & epub to epub convert in calibre that it is to go to sigil, set it to code view, set its find /replace to all files, all instances & then make the changes that way, but if leading trailing space cant be used....

& I guess there are other valid reasons for wanting to add extra ( normal) space via the search / replace engine

Use a unicode space character that isn't stripped. Since I didn;t write this bit of code, I cannot comment on why leading/trailing spaces are stripped, but I'd imagine it is to be consistent with the way spaces are handled everywhere else in calibre.

class Widget function get_value in calibre/gui2/convert/__init__.py is stripping white space at the beginning and end of QLineEdit and QTextEdit. So the spaces are never propagated along to the conversion pipeline.

You can override that behavior in the widget for search and replace. I don;t want to change it globally.

Change for white space to be kept only in the S&R widget pushed to my branch and ready for review.

The majority (I think all but one) of the bugs and enhancements cybmole has brought up have been either fixed or implemented.

He had string of rejections that had him seem to be down in the dumps. Just celebrating a victory.

Thanks for the fix, it sounds like one I might have run into in the future if it hadn't been fixed now.
