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

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

descripter = ExpressionDescriptor(
    expression = "*/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
options.use_24hour_time_format = True
descripter = ExpressionDescriptor("*/10 * * * *", options)
print(descripter.get_description(DescriptionTypeEnum.FULL))

Translating

cron-descriptor is using Gettext for translations.

To create new translation or edit existing one, i suggest using Poedit.

You can copy/rename and translate any file from locale directory:

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:

cd cron_descriptor
xgettext *.py -o locale/YOUR_LOCALE_CODE.po

Generating *.mo file from *.po file. In root directory run command:

msgfmt -o cron_descriptor/locale/YOUR_LOCALE_CODE.mo cron_descriptor/locale/YOUR_LOCALE_CODE.po
