`abrg download` command

Downloads the necessary dataset for geocoding from the Address Base Registry and builds the database using SQLite.

abrg download [options]

You can specify a particular prefecture or municipality to build a localized database, reducing the data size and speeding up database construction.
Use the National Local Government Codes to specify the region(s). Separate multiple regions with spaces.
```
# Download data for Tokyo
abrg download -c 130001

# Download data for Tokyo and Kanagawa
abrg download -c 130001 140007

# Download data for Chiyoda ward
abrg download -c 131016
```
You can change the directory to download the dataset files and save the database. The default is $HOME/.abr-geocoder.
```
abrg download -d (path to directory to save data)
```
```
abrg download --silent
```
```
abrg download --debug
```

`abrg update-check` command

Checks for data updates. If there is local data, it checks for updates in the municipalities contained in the database. If new data is available, it can be downloaded.

abrg update-check [options]

# Continue downloading
abrg update-check --yes

# Do not continue downloading
abrg update-check --no

```
abrg update-check --silent
```
Specifies the directory to save the database. The default is $HOME/.abr-geocoder.
```
abrg update-check -d (path to directory to save data)
```
```
abrg update-check --debug
```

`abrg` command

Geocodes the input address string with the database and outputs normalized address strings, town IDs, latitude, longitude, etc.

$ abrg <inputFile> [<outputFile>] [options]

<inputFile>

Specifies how to input data into the command.

Example:

abrg ./sample.txt

sample.txt:

東京都千代田区紀尾井町1-3   // 1-3 Kioicho, Chiyoda-ku, Tokyo

...
東京都千代田区永田町一丁目7番1号  // 1-7-1 Nagatacho, Chiyoda-ku, Tokyo

Example:

echo "東京都千代田区紀尾井町1-3　東京ガーデンテラス紀尾井町 19階、20階" | abrg -

<outputFile>
Specifies where to output the processing results. If omitted, outputs to standard output (stdout).
- Example:
```
abrg ./input.txt ./output.json
```
- Example:
```
cat ./sample.txt | abrg - | jq
```

You can change the output format with the -f, --format option. The default is json.

format	Description
csv	Outputs results in comma-separated csv format
simplified	Outputs results in comma-separated csv format with limited fields
json	Outputs results in JSON format
ndjson	Outputs results in NDJSON format
geojson	Outputs results in GeoJSON format
ndgeojson	Outputs results in NDGeoJSON format

Example:

echo "東京都町●市森野2-2-22" | abrg - --fuzzy "●"

```
abrg ./input.txt ./output.txt --silent
```
Specifies the directory to save the database. The default is $HOME/.abr-geocoder.
```
abrg ./input.txt ./output.txt  -d (path to directory to save data)
```
```
abrg ./input.txt ./output.txt --debug
```

`abrg serve` command

Starts the geocoder as a REST API server.

abrg serve [options]

Changes the port number for the REST API server. The default is 3000.
```
abrg serve -p 8080
```
Specifies the directory to save the database. The default is $HOME/.abr-geocoder.
```
abrg serve  -d (path to directory to save data)
```
