py-translate¶

Features¶

• Made for Python 3 but still works on Python 2
• Fast and easy to install, easy to use
• Supports translation from any language
• Highly composable interface, the power of Unix pipes and filters.
• Simple API and documentation

Installation¶

$ pip install py-translate

$ git clone https://github.com/jjangsangy/py-translate.git

$ python setup.py install

Usage¶

Examples¶

Hello World from English to Traditional Chinese

$ translate en zh-TW <<< 'Hello World!'
你好世界！

Hello World

• Just as easily specify a source language by providing it as first argument

# Translate Hello from French to English
$ translate fr en <<< 'Bonjour, comment allez-vous!'
Hello, how are you?

$ translate fr <<< 'I think therefore I am'
Je pense donc je suis

$ translate --translit en ko <<< 'Want to fight!'
ssaugo sip-eo!

$ translate --translit en zh-TW <<< 'Kidding, we should be friends'
Kāiwánxiào, wǒmen yīnggāi shì péngyǒu

$ translate zh-TW < 'alice.txt'

阿麗思道：「你不是說你要告訴你的歷史嗎？告訴我你為甚麼恨—那個—那些—C和D，」
她末了兩個字母輕輕兒地說的，怕回來又得罪了牠。

那老鼠對著阿麗思嘆了一口氣道，「唉﹗我的身世說來可真是又長又苦又委屈呀—」

阿麗思聽了，瞧著那老鼠的尾巴說，「你這尾是曲啊﹗可是為甚麼又叫它苦呢﹗」
她就一頭聽著那老鼠說話，一頭在在心上納悶，所以她聽的那老鼠講的「尾曲」
的歷史是差不多像這個樣了的

What is love?

Arguments¶

Requires at least one command line argument for the destination language. If no command line arguments are passed, an error message will be passed.

$ translate | "Error! No Arguments"

usage: translate [-h] [-v] [-l [code]] [source] dest

translate: error: the following arguments are required: dest

See Usage section for usage information

Language Codes¶

Use the -l option to see all the possible language codes.

$ translate -l

Specify the output format by language code

$ translate -l zh-TW

From PyPI¶

• To install py-translate, simply:

$ pip install py-translate

From Source¶

• Installation from the Git source repository.

$ git clone https://github.com/jjangsangy/py-translate.git

• Use setup.py

$ python setup.py install

OS X Installation¶

For full installation instructions for OS X, please visit Mac OS X Full Installation

1. Installing XCode or Command Line Tools¶

By default, Apple does not package OS X with it’s own C Compiler.

The default way would be to download and install XCode. which is free to anyone with an apple account and can be installed through the App Store.

Another option for Lion, Mountain Lion and Mavericks users, Apple now provides an official Command Line Tools for Xcode package that you can install without needing to install Xcode itself!

You can download it from Apple’s developer site (free registration required) and search for “Command Line Tools”.

2. Install Homebrew¶

Once we have installed GCC and/or command line tools installing homebrew is very straightforward.

Open up a terminal window and enter

$ ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

This will install the homebrew package manager in you /usr/local/.

Any packages that you will install, including python can be found in this directory.

We also need to make sure that /usr/local/ is in our $PATH enviornment before the /bin. In order to do that, run this command.

echo export PATH="/usr/local/bin:$PATH" >> ~/.profile

Now we’re all set to start installing some packages!

3. Install Python¶

First make sure that homebrew is up to date

$ brew update && brew upgrade

Already up-to-date.

Now we are ready to install python.

$ brew install python

To install the latest version of Python 3.

$ brew install python3

This will also include pip your python package manager.

First we need to make sure that everything is up to date.

$ pip install --upgrade setuptools
$ pip install --upgrade distribute
$ pip install --upgrade pip
$ pip install --upgrade wheel

Now we’re all ready, we can install py-translate directly from PyPI

$ pip install py-translate

And we’re done!

translate [-h] [-V] [-l [code]] [source] dest¶

py-translate

CLI Tool for Google Translate written in Python!

positional arguments¶

source¶

Source language code

dest¶

Destination language code

If only 1 positional argument is specified, it will be assumed to be dest and source will default to english

optional arguments¶

-h, --help¶

displays this help message and exit

-v, --version¶

show program’s version number and exit

-l, --lang [code]¶

List out available language codes [can output in different languages]

Translator Co-Routine¶

translate.translator(source, target, phrase, version='0.0 test', charset='utf-8')[source]¶

Returns the url encoded string that will be pushed to the translation server for parsing.

List of acceptable language codes for source and target languages can be found as a JSON file in the etc directory.

Some source languages are limited in scope of the possible target languages that are available.

>>> from translate import translator
>>> translator('en', 'zh-TW', 'Hello World!')
    '你好世界！'

Parameters:	source (String) – Language code for translation source target (String) – Language code that source will be translate into phrase (String) – Text body string that will be url encoded and translated
Returns:	Request Interface
Return type:	Dictionary

translate.coroutine(func)[source]¶

Initializes coroutine essentially priming it to the yield statement. Used as a decorator over functions that generate coroutines.

# Basic coroutine producer/consumer pattern
from translate import coroutine

@coroutine
def coroutine_foo(bar):
    try:
        while True:
            baz = (yield)
            bar.send(baz)

    except GeneratorExit:
        bar.close()

Parameters:	func (Function) – Unprimed Generator
Returns:	Initialized Coroutine
Return type:	Function

HTTP Delegation¶

translate.push_url(interface)[source]¶

Decorates a function returning the url of translation API. Creates and maintains HTTP connection state

Returns a dict response object from the server containing the translated text and metadata of the request body

Parameters:	interface (Function) – Callable Request Interface

Stream Caching¶

translate.source(target, inputstream=<_io.TextIOWrapper name='<stdin>' mode='r' encoding='ANSI_X3.4-1968'>)[source]¶

Coroutine starting point. Produces text stream and forwards to consumers

Parameters:	target (Coroutine) – Target coroutine consumer inputstream (BufferedTextIO Object) – Input Source

translate.spool(iterable, maxlen=1250)[source]¶

Consumes text streams and spools them together for more io efficient processes.

Parameters:	iterable (Coroutine) – Sends text stream for further processing maxlen (Integer) – Maximum query string size

translate.set_task(translator, translit=False)[source]¶

Task Setter Coroutine

End point destination coroutine of a purely consumer type. Delegates Text IO to the write_stream function.

Parameters:	translation_function (Function) – Translator translit (Boolean) – Transliteration Switch

translate.write_stream(script, output='trans')[source]¶

Parameters:	script (Iterable) – Translated Text output (String) – Output Type (either ‘trans’ or ‘translit’)

translate.accumulator(init, update)[source]¶

Generic accumulator function.

# Simplest Form
>>> a = 'this' + ' '
>>> b = 'that'
>>> c = functools.reduce(accumulator, a, b)
>>> c
'this that'

# The type of the initial value determines output type.
>>> a = 5
>>> b = Hello
>>> c = functools.reduce(accumulator, a, b)
>>> c
10

Parameters:	init – Initial Value update – Value to accumulate
Returns:	Combined Values

Multitasking¶

translate.set_task(translator, translit=False)[source]

Task Setter Coroutine

End point destination coroutine of a purely consumer type. Delegates Text IO to the write_stream function.

Parameters:	translation_function (Function) – Translator translit (Boolean) – Transliteration Switch

Writer¶

translate.write_stream(script, output='trans')[source]

Parameters:	script (Iterable) – Translated Text output (String) – Output Type (either ‘trans’ or ‘translit’)

Language Code Generation¶

translate.translation_table(language, filepath='supported_translations.json')[source]¶

Opens up file located under the etc directory containing language codes and prints them out.

Parameters:	file (str) – Path to location of json file
Returns:	language codes
Return type:	dict

translate.print_table(language)[source]¶

Generates a formatted table of language codes

translate

Access to library is done primarily through the application called translate which will be installed and accessed through a directory under users $PATH envar.
