I read about BBEdit on HN a few months ago and realized it has one use-case where it excels: text transformation and regex search/replace across files. When it comes to this, no other editor I know can hold water: neither Sublime, nor VS Code, nor Vim. And forget about Emacs, as regexes need to be awkwardly double or triple backslashed.

Text transformations can be done via regex, predefined functions, or any scripting language, where the scripts will be listed in the menu.

Regex search/replace has a history of used patterns, so you can reuse them.

All in all, it is a very lightweight editor with excellent text transformation features that no other editor can offer.

I use VS Code for coding, Emacs as a Lisp machine and its macro recorder for repetitive tasks, and BBEdit for all other text transformation tasks.
