The best text editor ever!

Ever since I've had a mac, I've used this app. Hands down, best text editor. Also, support is outstanding.

Single Purpose Tool

If you are looking for a text editor with very few bells and whistles, this is it. I live in a world where I regulary use three text editors and this is one of them. I have used SubEthaEdit since the time it was “free” and have paid for it a couple of times now. I do not use it for collboration, I use its Block Edit functionality. I can honestly say that the time this one feature has saved me over the years is well worth the money I spent. My one complaint about this product is the lack of documentation. I am sure that there are gems hidden under the covers, but frankly the documentation is non-existent.

Great product, but there’s a bug in this version

I’ve been using this editor for many years and am happy to see it back in active development.

There’s a small bug when using regular expression search with windows line endings. It doesn’t count the \r character as part of the line ending. So if you want to find all the lines ending in ‘a’ for instance, you would need to search for ‘a\r$’ as opposed to ‘a$’ if the file uses windows line endings.
