vtrans

GitHub license PyPI version

vtrans is a self-updating, free, and unlimited language translating library. It works with the googletrans library.

*Wait, but this is not like googletrans. googletrans can't update its languages, so you can only use limited languages. However, vtrans is different. It updates itself every time you import it.

Features

Different from googletrans

  • update it self
  • You can use exatra langauges like sansrit,bhojpuri ect....... .
  • but googletrans have not this languages
  • When the google update their google translator it automatically update it self
  • you can use extra languages compare to other translating library
  • what langauges are avaiable in google translator,you can use all the languages by this library

Similarities with googletrans

  • Fast and reliable: It uses the same servers as translate.google.com.
  • Auto language detection
  • Bulk translations
  • HTTP/2 support
  • Similar structure

How it works

vtrans is essentially a language-updatable version of googletrans. It modifies the LANGUAGES dictionary in constants.py of googletrans by scraping the table from google translator supported langauges. It retrieves the values from the table and creates a new dictionary, which replaces the existing LANGUAGES dictionary.

Installing

To install the vtrans package, use the following command:

$ pip install vtrans==3.0.0

How to use this library (simple)

from vtrans import Translator

translator = Translator()
output = translator.translate("This library can translate languages", "ta")

Find available languages

To find what languages are available in vtrans:

import vtrans

langs = vtrans.LANGUAGES
print(langs)  # It will give you a dictionary

# To find the number of available languages
print(len(langs))

First importing of vtrans

If you import this library for the first time, it will take some time to complete the configurations. It changes the LANGUAGES variable in constants.py of googletrans to match the current version of Google Translator. The first import will display the following:

import vtrans

# Setup config file
# Checking for updates (auto-updating). If you want to stop auto-updating, use this code: `vtrans.config(auto_updating=False)`
# Please wait for a few seconds, the update is in progress...
# Update finished. Now you can use extra languages.
# Ready to translate

Once you have imported vtrans for the first time, you do not need to use auto-updating. Auto-updating slows down the library, as it searches for updates whenever you import vtrans. Enabling or disabling auto-updating is based on your needs and choice.

How to disable auto-update

If you want to disable auto-updating:

import vtrans

vtrans.config(auto_updating=False)

Now vtrans will not update whenever you import it.

How to update manually

If you want to update manually, make sure you have disabled auto-updating:

import vtrans

vtrans.update()

Now the languages are updated manually.

How to disable unwanted printing

Whenever vtrans is initialized and ready to translate, it prints "Ready to translate". If you want to disable this:

import vtrans

vtrans.remove_unwanted_printing()

You don't need to do this every time. Once you have changed the value, it will make changes in the config.txt file.

HTTP/2 support

This library uses httpx for HTTP requests, so HTTP/2 is supported by default. You can check if HTTP/2 is enabled and working by accessing the ._response.http_version attribute of the Translated or Detected object:

translator.translate('테스트')._response.http_version
# 'HTTP/2'

Basic Usage

If the source language is not given, Google Translate attempts to detect the source language.

from vtrans import Translator

translator = Translator()
translator.translate('안녕하세요.')
# <Translated src=ko dest=en text=Good evening. pronunciation=Good evening.>
translator.translate('안녕하세요.', dest='ja')
# <Translated src=ko dest=ja text=こんにちは。 pronunciation=Kon'nichiwa.>
translator.translate('veritas lux mea', src='la')
# <Translated src=la dest=en text=The truth is my light pronunciation=The truth is my light>

Customize service URL

You can use a different Google Translate domain for translation. If multiple URLs are provided, it randomly chooses a domain.

from vtrans import Translator

translator = Translator(service_urls=[
    'translate.google.com',
    'translate.google.co.kr',
])

Advanced Usage (Bulk)

Arrays can be used to translate a batch of strings in a single method call and a single HTTP session. The same method shown above also works for arrays.

translations = translator.translate(['The quick brown fox', 'jumps over', 'the lazy dog'], dest='ko')
for translation in translations:
    print(translation.origin, ' -> ', translation.text)
# The quick brown fox  ->  빠른 갈색 여우
# jumps over  ->  이상 점프
# the lazy dog  ->  게으른 개

Language detection

The detect method identifies the language used in a given sentence.

from vtrans import Translator

translator = Translator()
translator.detect('이 문장은 한글로 쓰여졌습니다.')
# <Detected lang=ko confidence=0.27041003>
translator.detect('この文章は日本語で書かれました。')
# <Detected lang=ja confidence=0.64889508>
translator.detect('This sentence is written in English.')
# <Detected lang=en confidence=0.22348526>
translator.detect('Tiu frazo estas skribita en Esperanto.')
# <Detected lang=eo confidence=0.10538048>

Note on library usage

DISCLAIMER: Yes, I am aware that most of the functions are similar to googletrans because I worked with the base of googletrans. However, vtrans can update its languages, allowing you to use more languages. This is an unofficial library that uses the web API of translate.google.com and is not associated with Google.

  • The maximum character limit on a single text is 15k.
  • Due to limitations of the web version of Google Translate, this API does not guarantee stability at all times. Please use this library if you don't require stability.
  • If you encounter HTTP 5xx errors or errors like #6, it is likely because Google has banned your client IP address.
