I'm working with a library that enters their LCC call numbers in the format "PN6728 .B36" rather than "PN 6728 .B36." This means that the default LCC splitting rule doesn't insert a line break between PN and 6728. So I wrote a regex splitting rule that does that fine. However, the regex splitting is only applied when using the full label creator. When printing via the quick spine label creator it appears to still be splitting based on the default LCC splitting rule.
Hi Andrew, the quick spine label creator and the label creator work quite differently. If you take a look at the source of the quick labels you might be able to achieve something with CSS/jQuery to get your labels to split like you want. Practically every character has its own class/id.
