# red - A Rust Editor

*red* is a line-oriented text editor, based on the popular [*ed* utility](http://pubs.opengroup.org/onlinepubs/009604599/utilities/ed.html).

It has two modes: *command mode* and *input mode*. In command mode the input characters are interpreted as commands, and in input mode they are interpreted as text.

Some of the history of *ed* is discussed in the article ["Where Vim Came From"](https://twobithistory.org/2018/08/05/where-vim-came-from.html).

## Installation

```

cargo install red-editor

```

## Usage

```

$ red file.txt

a

Hello World!

.

w

13

1,$p

Hello World!

q

```

## Available commands

* `q` - Quit the editor. If the buffer has changed since the last time it was written, a warning is saved and the editor is not quit. A successive `q` command will exit.

* `Q` - Quit the editor without checking whether changes are unsaved.

* `(.,.)p` - Print the addressed lines to standard output.

* `(.,.)n` - Print the addressed lines to standard output, preceding each line by its line number and a <tab>.

* `(.,.)d` - Delete the addressed lines from the buffer.

* `(.,.)w [file]` - Write the addressed lines to the named file. The pathname is remembered for following writes.

* `(.)a` - Append text after the addressed line. End text input with a single `.` in a line.

* `(.)i` - Insert text before the addressed line. End text input with a single `.` in a line.

* `h` - Write a short message to standard output that explains the reason for the most recent `?`.

* `e [file]` - Delete the entire contents of the buffer and read the specified file into the buffer.

* `(.,.)c` - Delete the addressed line, then accept input text to replace these lines.

* `(.)r [file]` - Read contents of another file and insert into the buffer.

* `(.,.)maddress` - Move the addressed lines after the line addressed by `address`.

* `(.,.)s/RE/replacement/flags` - Search the addressed lines for an occurence of `RE` and substitute either the first or all matched strings with `replacement`. Supported flags: **g** to globally substitute instances of `RE`.

## Not (yet) implemented

* `/` - Addressing lines by search.

* `(.,.)g/RE/command` - Global regular expression search.

* `'x` - Marking lines with a name.
