Geo::TAF

I recently had the opportunity to test out Geo::TAF, a useful Perl module designed to decode METAR and TAF weather forecast code strings into English, or other programmed languages (if subclassed).

The SYNOPSIS provided in the documentation was fairly straightforward, allowing me to quickly start using the module.

One useful feature was the ability to decode either METAR or TAF strings using the following functions:

- `$t->metar("EGSH 311420Z 29010KT 1600 SHSN SCT004 BKN006 01/M00 Q1021");`
- `$t->taf("EGSH 311205Z 311322 04010KT 9999 SCT020 TEMPO 1319 3000 SHSN BKN008 PROB30 TEMPO 1318 0700 +SHSN VV/// BECMG 1619 22005KT");`
- `$t->decode("METAR EGSH 311420Z 29010KT 1600 SHSN SCT004 BKN006 01/M00 Q1021");`
- `$t->decode("TAF EGSH 311205Z 311322 04010KT 9999 SCT020 TEMPO 1319 3000 SHSN BKN008 PROB30 TEMPO 1318 0700 +SHSN VV/// BECMG 1619 22005KT");`

The ability to loop through the different chunks of weather data using `foreach` was a helpful feature. The following code can be used to display the raw chunk data:

```
foreach my $c ($t->chunks) {
print $c->as_string, ' ';
}
```

Alternatively, the decoded chunk string data can be displayed using:

```
print $self->as_string;
```

Users can also retrieve the chunks and chunk strings if needed, using:

```
foreach my $c ($t->chunks) {
print $c->as_chunk, ' ';
}

print $self->as_chunk_string;
```

Lastly, the `is_weather` function was a helpful tool for identifying whether a given string of data was weather-related or not. The following code can be used to determine whether a line is weather-related:

```
print Geo::TAF::is_weather($line) ? 1 : 0;
```

Overall, I found Geo::TAF to be a useful Perl module for decoding weather forecast code strings. It was easy to use and provided useful functions for interpreting weather data.
