local-lang 0.0.17

A small package to localise your python application

LocalLang

Installation

pip install local-lang

Description

LocalLang is a simple library to manage localization in your python program. It allows you to create a json file for each language you want to support. You can use placeholders in your translation and specify the type of the placeholder. You can also specify the format for the datetime and time type.

This package converts your json file to a Python class with all your translation. You can then use this class to get your translation.

Usage

locallang --help  # Show help
locallang --default-lang en  # Reload localisation
locallang  # Reload localisation but the default language is en_us
locallang --version  # Show version

Json file structure

placeholders is optional

no_f_string is optional

• This parameter is used to disable the use of f-string in the localization if you use {} in your translation.

format is only for datetime and time type

{
  "key": "value {placeholder_name}",
  "@key": {
    "no_f_string": "bool",
    "placeholders": {
      "placeholder_name": {
        "type": "str|int|float|bool|datetime|time",
        "format": "format"
      }
    }
  }
}

Example

test.py

from locallang import LangInit, getLocalisation
import datetime

localisation = LangInit()

local = getLocalisation(local="en_us")

print(local.hey())
print(local.hello_world())
print(local.toDay(date=datetime.datetime.now()))
print(local.thisTime(time=datetime.datetime.now().time()))
print(local.testStr(strText="Hello world!"))
print(local.testInt(intNum=1))
print(local.testFloat(floatNum=1.5))
print(local.testBool(boolValue=True))
print(local.test(test=1.5))

local = getLocalisation(local="fr")

print(local.hey())
print(local.hello_world())
print(local.toDay(date=datetime.datetime.now()))
print(local.thisTime(time=datetime.datetime.now().time()))
print(local.testStr(strText="Bonjour tout le monde !"))
print(local.testInt(intNum=2))
print(local.testFloat(floatNum=2.5))
print(local.testBool(boolValue=False))
print(local.test(test="coucou"))
