print(str(ExpressionDescriptor("* 2 3 * *")))
```

```python
# Advanced
# Consult Options.py/CasingTypeEnum.py/DescriptionTypeEnum.py for more info
from cron_descriptor import Options, CasingTypeEnum, DescriptionTypeEnum, ExpressionDescriptor

descripter = ExpressionDescriptor("*/10 * * * *", throw_exception_on_parse_error = True, casing_type = CasingTypeEnum.Sentence, use_24hour_time_format = True)
# GetDescription uses DescriptionTypeEnum.FULL by default:
print(descripter.get_description())
print("{}".format(descripter))

#or passing Options class as second argument:

options = Options()
options.throw_exception_on_parse_error = True
options.casing_type = CasingTypeEnum.Sentence

## Translating
cron-descriptor is using [Gettext](https://www.gnu.org/software/gettext/) for translations.

> To create new translation or edit existing one, i suggest using [Poedit](https://poedit.net/).

You can copy/rename and translate any file from `locale` directory:
```bash
cp ./cron_descriptor/locale/de_DE.po ./cron_descriptor/locale/YOUR_LOCALE_CODE.po
poedit ./cron_descriptor/locale/YOUR_LOCALE_CODE.po
```
or you can generate new untranslated *.po file from sources by running in `cron_descriptor` directory:
```bash
cd cron_descriptor
xgettext *.py -o locale/YOUR_LOCALE_CODE.po
```

Generating *.mo file from *.po file. In root directory run command:
```bash
msgfmt -o cron_descriptor/locale/YOUR_LOCALE_CODE.mo cron_descriptor/locale/YOUR_LOCALE_CODE.po
```
