Is there a character limit to GREP expressions with a certain paragraph style? I implemented a number of nested GREP styles in my company’s templates a few years ago. One is a long list of alternations to catch certain source material that is always italicized in copyright lines. i.e. (?:source 1|source 2|source 3|etc). I use a script to update this list from a text file that we update when new sources are added. That GREP expression is now over 5000 characters long. It still works flawlessly in conjunction with the other nested styles on that paragraph style. However, I am unable to manually create any more nested GREP styles without a lot of buggy behavior. I can create a new style, but when I select the character style or enter a GREP expression, they revert to the defaults (“[no style] and “\d+” respectively). When I reduce the list of 5000 down to 3000 or so, I don’t have any issues. I tried splitting that list into two expressions of 2500 each, but the same behavior persists. Any insights?
