##### ISS spotting with `--level`, `--soon` & `--prediction`

Just a note about what `--level` does and how it interacts with the optional arguments in `--soon` and `--prediction`:

With `--level` you set what you get:

| Level       | When?                        | Format             | Example          |
|-------------|------------------------------|--------------------|------------------|
| `watch`     | only if currently visible    | `🛰+`*duration*    | `🛰+03:12`      |
| `soon`      | only if visible within *soon*| `🛰-`*duration*    | `🛰-12:34`      |
| `rise`      | when there is any prediction | `🛰`*[date] time*  | `🛰12:15`      |
| `far`       | prediction time in days if no prediction available | `🛰>`*days*   | `🛰>16`      |

Levels are inclusive backwards. So if you set the level to `rise` you will see `soon` and `watch` events too.

An event is "soon" if it happens within the number of minutes you set with option `--soon`.

The value given by argument `--prediction` sets the number of spotting events that will be fetched from *api.open-notify.org*. So this value somehow limits the time of prediction. A maximum of 100 events is given by *api.open-notify.org*.

### Display Format

#### Available Properties

Choose your display format by inserting the following properties keys into your format string:

| Key               | Description | Example |
|-------------------|-------------|---------|
| `{city}`          |  City name | `Berlin` |
| `{main}`          |  Group of weather parameters | `Clouds` |
| `{description}`   |  Weather condition within the group | `scattered clouds` |
| `{icon}`          |  Weather icon | `🌞`,`🌛`, `🌤`, `⛅`, `🌧`,`🌦`,`🌩`,`❄`,`🌫` |
| `{pressure}`      |  Atmospheric pressure (sea level or ground level), hPa | `1010` |
| `{humidity}`      |  Humidity, % | `45` |
| `{wind}`          |  Wind direction | `N`, `NO`, `O`, `SO`, `S`, `SW`, `W`, `NW` |
| `{wind_icon}`     |  Wind direction as arrow icon | `↓`, `↙`, `←`, `↖`, `↑`, `↗`, `→`, `↘` |
| `{wind_speed}`    |  Wind speed | `m/s`, `mi/h` |
| `{wind_deg}`      |  Wind direction, degrees (meteorological) | `56` |
| `{deg_unit}`      |  Direction unit | `°` |
| `{visibility}`    |  Visibility, meter | `10000` |
| `{visibility_km}` |  Visibility, kilometer | `10` |
| `{rain.1h}`       |  Rain volume for the last 1 hour, mm | `12` |
| `{rain.3h}`       |  Rain volume for the last 3 hours, mm | `32` |
| `{snow.1h}`       |  Snow volume for the last 1 hour, mm | `11` |
| `{snow.3h}`       |  Snow volume for the last 3 hours, mm | `24` |
| `{temp_min}`      |  Minimum temperature at the moment | `-8` |
| `{temp_max}`      |  Maximum temperature at the moment | `10` |
| `{feels_like}`    |  Temperature for the human perception of weather | `8` |
| `{temp}`          |  Temperature | `15` |
| `{temp_unit}`     |  Temperature | `°C`, `°F`, `K` |
| `{speed_unit}`    |  Wind speed unit | `m/s` |
| `{update}`        |  Local time of last update | `12:45` |
| `{iss}`           |  ISS spotting time, latency or duration | `+01:15` , `-02:21`, `12:10`, `>16` |
| `{iss_icon}`      |  show icon if ISS is visible | `🛰` |  
| `{iss_space}`     |  inserts space (`' '`) if any ISS information is displayed | ` ` |

#### Testing your Display Format

To make testing easy *i3owm* has an option `-t` (or `--test`) which disables processing of input from i3status and just produces the *i3owm* related output string.
We use that option to test some examples without *i3status*.

##### Weather

To get the weather we could use the following command line:

```
i3owm -t -k <key> -c Berlin,DE -f '{icon} {temp}{temp_unit} 💧{humidity}%'
```

###### Output

```
loading...
⛅ 11°C 💧55%
```

##### ISS Spotting Events

To get ISS spotting events we could use the following parameters:

```
i3owm -t -Lrise -k <key> -c Berlin,DE -f 'before {iss_icon}{iss}{iss_space}after'
```

This example would show the satellite icon, a time for ISS spotting and a space ` ` separator if any prediction can be made:

###### Output

```
loading...
before 🛰+03:12 after
```
...or...

```
loading...
before after
```

...if no ISS status is available.

This would mean that ISS is already visible for 3:12 minutes.

##### Complex Example

In this complex example we use the following parameters:

```
i3owm -tnb -Lrise -C100 -k <key> -cBerlin -f'{iss_icon}{iss}{iss_space}{icon} {temp}{temp_unit} 💧{humidity}% {wind_icon}{wind_speed}{speed_unit} ({update})'
```

###### Output

```
loading...
⛅ 14°C 💧70% ↑2m/s (13:47)
🛰16:37 ⛅ 14°C 💧70% ↑2m/s (13:47)
```

### Integration into i3status

To use your *i3owm* command line in your i3 configuration you need to remove option `-t` and append a pipe symbol `|` and your command line to your it (usually at `.config/i3/config`).

```
bar {
  status_command i3status | i3owm <your options>
}
```
