# Ze ed

Like deez, but backwards.

Ze is a terminal [vim](https://www.vim.org/)-like text editor.

It uses a *treap* data structure to represent file by lines and remembers versions with added *semi-persistence*.

## Dependencies

* `ncurses` c library

## Build

Described in the `Makefile`

## Usage

`ze <filename>`

## Modes

Ze has three modes within which you can edit a file - *normal*, *insert* and *select*.
Those represent what the user is currently doing:
* *insert* mode: Writing text
* *select* mode: Operations on a selection
* *normal* mode: Everything else
