# redraw

An interactive terminal tool to filter and redraw output continuously.

[![asciicast](https://asciinema.org/a/478249.svg)](https://asciinema.org/a/478249)

I was frustrated with terminal commands like `column`, `sort`, `wc` not

showing any output until they encounter an EOF. So I wrote `redraw` to run

those commands on every new line and redraw the terminal output with 

terminal escape sequences.

With `redraw` you can provide a updates to terminal commands before the input

reaches EOF, resulting in a more interactive experience.

Example usage:

You'd want to format output with `column -t` but the lines are arriving 

slowly. Instead of staring at a blank screen for minutes, you can appreciate

the formatted output as the results are coming in.

Instead of this:

```bash

your_command | column -t

```

Write this:

```bash

your_command | redraw column -t

```

If your downstream pipeline consists of multiple piped commands:

Instead of this:

```bash

your_command | command_a | command_b | command_c

```

You could write this:

```bash

your_command | redraw bash -c 'command_a | command_b | command_c'

```

TODO: we could have a line editor script performing the back and forth conversion.
