How to modify calibre text sort algorithm

[khonshu]

Hello all.

Most of my books are in spanish and so I have titles with beginning exclamation and question marks (¿ and ¡). I would like to add that symbols to the list of articles to be ignored when sorting text but I'm getting an error.

The items I'm adding are:

u'¿\\s+'),
u'¡\\s+'),

The error is:

calibre, version 4.9.1

Traceback (most recent call last):
File "site-packages\calibre\gui2\preferences\tweaks.py", line 535, in apply_tweak
File "<string>", line 93
u'¿\\s+'),
^
SyntaxError: invalid syntax

The arrow points the + symbol after the s.

Of course someone would think of removing such caracters from the title but we are talking about a few thousand books. Any help would be welcome. Thanks.

did you add that single ' at the end because it is part of the article? (English only speaker here ) ?
You might need to escape it (removes special meanings):
\'
As to removing anything from any field
Metadata edit Bulk mode (2 or more items selected before entering the MDE), Search and replace tab
backup your metadata.db, you goof, and a lot of data could go south.
Create a practice library of a few COPIES, you can even SAVE the S&R while practicing. It will be available when you switch back to the main Library (assumes both have the same columns involved)

The problem is actually the right parenthesis. The error dialog uses a proportional font, and the characters in the line do not line up properly. I have wrapped the error in code tags to show this.

You should be using just:

 u'¿\\s+',
 u'¡\\s+',

The last comma is should be OK.

Solved, thank you! The problem was the closing parenthesis.
