```python

from cron_descriptor import Options, CasingTypeEnum, DescriptionTypeEnum, ExpressionDescriptor

descriptor = ExpressionDescriptor(
    expression = "*/10 * * * *",

print(descriptor.get_description())
print(f"{descriptor = }")

# Or passing Options class as second argument:

options = Options()
options.casing_type = CasingTypeEnum.Sentence
options.use_24hour_time_format = True

## Running Unit Tests

```bash
python setup.py test
```

## 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
```
