Is there a great text editor for iPhone and/or iPad with BBEdit-style text filters and PCRE search/replace?
Solution 1:
The iOS Text Editor roundup is an interactive table with about 70 current text editors for iPad and/or iPhone. You may click on the features you desire at the top of the table and only the editors that have your selected features will be displayed. The table also lists the cost of each editor. If you don't see the feature you're looking for, download a free editor from your list and give it a try.
