rest.

# Why?

You can [cook](https://ratatui.rs/) a terminal. But can you **deep fry** a terminal?
*YES!* You can **cook *and* fry** your `tty`! ~~Run before it's too late!~~

> The terminal is usually in "cooked" mode, or canonical mode.
> With `ratatui`🐁, it's in raw mode, but it "cooks" for you.

Markdown can obviously be rendered pretty well in terminals, but one key aspect is missing: 
Big Headers™ make text more readable, and rendering images inline is very convenient.

# How?

By rendering the headers as [images with ratatui](https://sw.kovidgoyal.net/kitty/text-sizing-protocol/),
and using one of several terminal graphics protocols: Sixels, Kitty, or iTerm2.
The Kitty terminal also implements a [Text Sizing Protocol](https://sw.kovidgoyal.net/kitty/text-sizing-protocol/)
to directly scale text without needing to render as images!

See [ratatui-image](https://github.com/benjajaja/ratatui-image?tab=readme-ov-file#compatibility-matrix)
to see if your terminal does even have graphics support, and for further details.

In general, Kitty, WezTerm, iTerm2, Ghostty, Foot, `xterm -ti vt340`, *should* work.

On terminals without graphics whatsoever, like Alactritty, images are rendered with Chafa.

# Usage

### Running

```
mdfried ./path/to.md
```

Unless you're using Kitty version 0.40 or greater, or a terminal that does not support any graphics
protocol, the first time you run `mdfried` you will have to pick a font.
You should pick the same font that your terminal is using, but you could pick any.
The font-setup screen lets you search the system fonts - you will want to pick the same font that
your terminal is using.
The font is rendered directly as a preview.
Once confirmed, the choice is written into the configuration file.

Use `--setup` to force the font-setup again if the font is not right.

You can also pipe markdown into it:

```
