OpenStreetMap but as terminal user interface (TUI) program and [Bubble
Tea](https://github.com/charmbracelet/bubbletea) Bubble.

## Build

```sh
$ go get
$ go build .
```

The binary is called `mercator`

## Usage

`mercator` accepts latitude and longitude as arguments, e.g.:

```sh
$ mercator 25.0782266 -77.3383438
```

It also accepts a location name or address, e.g.:

```sh
$ mercator miami
```

### Style

`mercator` accepts the `-style` flag with an integer value representing one of
the options [listed as
`Style`](https://github.com/mrusme/mercator/blob/master/mapview/mapview.go#L24),
e.g.:

```sh
$ mercator -style 4 new york
```

### Navigation

- `arrow up`/`k`: Move north
- `arrow right`/`l`: Move east
- `arrow down`/`j`: Move south
- `arrow left`/`h`: Move west
- `-`/`_`: Zoom out
- `+`/`=`: Zoom in

## Bubble

You can embed the `mapview` into your Bubble Tea application:

```go
package main

import (
tea "github.com/charmbracelet/bubbletea"
"github.com/mrusme/mercator/mapview"
)

type model struct {
mv mapview.Model
}

func main() {
m := NewModel()
m.mv.SetLocation("jamaica", 15)

p := tea.NewProgram(m, tea.WithAltScreen())
if _, err := p.Run(); err != nil {
panic(err)
}
}

func NewModel() model {
m := model{}
m.mv = mapview.New(80, 24)
return m
}

func (m model) Init() tea.Cmd {
return tea.Batch(tea.EnterAltScreen)
}

func (m model) Update(msg tea.Msg) (tea.Model, tea.Cmd) {
switch mt := msg.(type) {
case tea.KeyMsg:
switch mt.String() {
case "q", "esc", "ctrl+c":
return m, tea.Quit
}

case tea.WindowSizeMsg:
m.mv.Width = mt.Width
m.mv.Height = mt.Height
return m, nil

}

var cmd tea.Cmd
m.mv, cmd = m.mv.Update(msg)
return m, cmd
}

func (m model) View() string {
return m.mv.View()
}
```
