Project description

humanize

:target: http://travis-ci.org/jmoiron/humanize

This modest package contains various common humanization utilities, like turning
a number into a fuzzy human readable duration ('3 minutes ago') or into a human
readable size or throughput. It works with python 2.7 and 3.3 and is localized
to Russian, French, and Korean.

usage
-----

Integer humanization::

>>> import humanize
>>> humanize.intcomma(12345)
'12,345'
>>> humanize.intword(123455913)
'123.5 million'
>>> humanize.intword(12345591313)
'12.3 billion'
>>> humanize.apnumber(4)
'four'
>>> humanize.apnumber(41)
'41'

Date & time humanization::

>>> import datetime
>>> humanize.naturalday(datetime.datetime.now())
'today'
>>> humanize.naturalday(datetime.datetime.now() - datetime.timedelta(days=1))
'yesterday'
>>> humanize.naturalday(datetime.date(2007, 6, 5))
'Jun 05'
>>> humanize.naturaldate(datetime.date(2007, 6, 5))
'Jun 05 2007'
>>> humanize.naturaltime(datetime.datetime.now() - datetime.timedelta(seconds=1))
'a second ago'
>>> humanize.naturaltime(datetime.datetime.now() - datetime.timedelta(seconds=3600))
'an hour ago'

Filesize humanization::

>>> humanize.naturalsize(1000000)
'1.0 MB'
>>> humanize.naturalsize(1000000, binary=True)
'976.6 KiB'
>>> humanize.naturalsize(1000000, gnu=True)
'976.6K'


Human readable floating point numbers::

>>> humanize.fractional(1/3)
'1/3'
>>> humanize.fractional(1.5)
'1 1/2'
>>> humanize.fractional(0.3)
'3/10'
>>> humanize.fractional(0.333)
'1/3'
>>> humanize.fractional(1)
'1'

Localization
------------

How to change locale in runtime ::

>>> print humanize.naturaltime(datetime.timedelta(seconds=3))
3 seconds ago
>>> _t = humanize.i18n.activate('ru_RU')
>>> print humanize.naturaltime(datetime.timedelta(seconds=3))
3 секунды назад
>>> humanize.i18n.deactivate()
>>> print humanize.naturaltime(datetime.timedelta(seconds=3))
3 seconds ago

You can pass additional parameter *path* to :func:`activate` to specify a path to
search locales in. ::

>>> humanize.i18n.activate('pt_BR')
IOError: [Errno 2] No translation file found for domain: 'humanize'
>>> humanize.i18n.activate('pt_BR', path='path/to/my/portuguese/translation/')
<gettext.GNUTranslations instance ...>

How to add new phrases to existing locale files ::

$ pybabel extract -o messages.pot -k _ -k N_ humanize # extract new phrases
$ pybabel update -i messages.pot -D humanize -d humanize/locale/

How to add new locale ::

$ pybabel init -i messages.pot -d humanize/locale/ -D humanize -l <lang abbreviation, eg 'en_GB'>
