Just in case you haven’t heard.
TextWrangler will very soon be a thing of the past.
If you want a copy be sure to get one soon, and be aware that as 32-bit software it will no longer work on new versions of macOS after the next revision or two.
BBEdit has gone back to “Lite” and “Pro” versions, although they are now contained in the same software envelope.
When you first install BBEdit it will have all professional features enabled (for 30 days), and if you don’t register in that time it will revert to the BBEdit-Lite version.
BBEdit-Lite is significantly more powerful than TextWrangler, so it’s a net gain for unregistered users.
Everyone who works with and processes text on a Macintosh should have a copy of BBEdit on their system.
BBEdit is very powerful and is one of the most AppleScriptable applications available — it’s scriptability makes it particularly useful in conjunction with Keyboard Maestro.
