Emacs
What is it?
A very old text editor dating back to the 70's.
Emacs is less of a text editor and more of a text editing platform. You can:
- Use as a kind of IDE
- Check your email
- Organize TODO items
Why use it?
- Insanely configurable
- Habit
- Efficient if you know how to use it
- Especially useful if you edit a lot of plain text
- Large ecosystem, email, TODO, etc.
It's a bit circular. You use emacs because you edit a lot of text. But you arrange to edit a lot of text (choosing text formats, etc.) because editing text can be done so effectively in Emacs.
