Following along with [Web Browser Engineering](https://browser.engineering/), in Go.

You will need to download the PNG Color 72x72 emoji pack from [OpenMoji](https://openmoji.org/) and

place it in `assets/openmoji` to render emoji.

To run tests:

```shell

$ go test ./internal

```

## Structure

1. The **URL fetcher** resolves the URL (`http://`, `https://`, `file:///`, etc.) and fetches the resource. (`urlfetcher.go`)

2. The resource is passed to the **GUI** to be shown. (`gui.go`)

3. The GUI calls the **layout engine** to compute the position of elements. (`layoutengine.go`)

4. The GUI draws the elements from the layout engine on the screen.

### URL fetcher

- HTTP request encoding

- HTTP request decoding

- TLS support (using the standard library)

- Other resources (`file:///`, `data:`, etc.)

### GUI

- Using SDL2 to draw things on the screen

- Handling user interaction: scrolling, resizing

### Layout engine

- Laying out text and elements

- Breaking long lines

- Positioning text based on font metrics
