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 is localized to:
* Brazilian Portuguese
* Dutch
* Finnish
* French
* German
* Indonesian
* Italian
* Japanese
* Korean
* Persian
* Russian
* Simplified Chinese
* Slovak
* Spanish
* Turkish
* Vietnamese
## Usage
### Integer humanization
```pycon
>>> 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
```pycon
>>> import humanize
>>> import datetime as dt
>>> humanize.naturalday(dt.datetime.now())
'today'
>>> humanize.naturaldelta(dt.timedelta(seconds=1001))
'16 minutes'
>>> humanize.naturalday(dt.datetime.now() - dt.timedelta(days=1))
'yesterday'
>>> humanize.naturalday(dt.date(2007, 6, 5))
'Jun 05'
>>> humanize.naturaldate(dt.date(2007, 6, 5))
'Jun 05 2007'
>>> humanize.naturaltime(dt.datetime.now() - dt.timedelta(seconds=1))
'a second ago'
>>> humanize.naturaltime(dt.datetime.now() - dt.timedelta(seconds=3600))
'an hour ago'
```
#### Smaller units
If seconds are too large, set `minimum_unit` to milliseconds or microseconds:
```pycon
>>> import humanize
>>> import datetime as dt
>>> humanize.naturaldelta(dt.timedelta(seconds=2))
'2 seconds'
```
```pycon
>>> delta = dt.timedelta(milliseconds=4)
>>> humanize.naturaldelta(delta)
'a moment'
>>> humanize.naturaldelta(delta, minimum_unit="milliseconds")
'4 milliseconds'
>>> humanize.naturaldelta(delta, minimum_unit="microseconds")
'4000 microseconds'
```
```pycon
>>> humanize.naturaltime(delta)
'now'
>>> humanize.naturaltime(delta, minimum_unit="milliseconds")
'4 milliseconds ago'
>>> humanize.naturaltime(delta, minimum_unit="microseconds")
'4000 microseconds ago'
```
### File size humanization
```pycon
>>> import humanize
>>> 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
```pycon
>>> import humanize
>>> 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'
```
### Scientific notation
```pycon
>>> import humanize
>>> humanize.scientific(0.3)
'3.00 x 10⁻¹'
>>> humanize.scientific(500)
'5.00 x 10²'
>>> humanize.scientific("20000")
'2.00 x 10⁴'
>>> humanize.scientific(1**10)
'1.00 x 10⁰'
>>> humanize.scientific(1**10, precision=1)
'1.0 x 10⁰'
>>> humanize.scientific(1**10, precision=0)
'1 x 10⁰'
```
## Localization
How to change locale at runtime:
```pycon
>>> import humanize
>>> import datetime as dt
>>> humanize.naturaltime(dt.timedelta(seconds=3))
3 seconds ago
>>> _t = humanize.i18n.activate("ru_RU")
>>> humanize.naturaltime(dt.timedelta(seconds=3))
3 секунды назад
>>> humanize.i18n.deactivate()
>>> humanize.naturaltime(dt.timedelta(seconds=3))
3 seconds ago
```
You can pass additional parameter `path` to `activate` to specify a path to search
locales in.
```pycon
>>> import humanize
>>> 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:
```console
$ xgettext --from-code=UTF-8 -o humanize.pot -k'_' -k'N_' -k'P_:1c,2' -l python src/humanize/*.py # extract new phrases
$ msgmerge -U src/humanize/locale/ru_RU/LC_MESSAGES/humanize.po humanize.pot # add them to locale files
$ msgfmt --check -o src/humanize/locale/ru_RU/LC_MESSAGES/humanize{.mo,.po} # compile to binary .mo
```
How to add a new locale:
```console
$ msginit -i humanize.pot -o humanize/locale/<locale name>/LC_MESSAGES/humanize.po --locale <locale name>
```
Where `<locale name>` is a locale abbreviation, eg. `en_GB`, `pt_BR` or just `ru`, `fr`
etc.
