Welcome to Repack!

Repack is a collection of well known utilities nicely packed together. To illustrate the idea, imagine, you need to pass an object via URL query string, with Repack it looks like:

import repack

token1 = (repack
            .json_encode()
            .bytify()
            .deflate()
            .base64_encode()
            .url_encode()
            .converter()
            .send({'id': 10001, 'desc':'this is a token' }))

But normally, you would do:

import json
import zlib
import base64
import urllib.parse

string = json.dumps({'id': 10001, 'desc':'this is a token' })
stream = bytes(string, 'utf-8')
stream = zlib.compress(stream)
string = base64.b64encode(stream)
token1 = urllib.parse.quote(string)

Feel the difference :) Also you want it to be lasy, so you can make a converter once and use it later:

urlit = (repack
            .json_encode()
            .bytify()
            .deflate()
            .base64_encode()
            .url_encode()
            .converter())

Like this:

token1 = urlit.send({'id': 10001, 'desc':'this is a token' })

Or like this:

token2 = urlit.send('another token lol')
token3 = urlit.send('one more yay')
token4 = urlit.send('yay!!!')

You can chain the utilities as filter, meaning, values interpreted as False will not pass:

with (repack
        .reverse()
        .printout()
        .filter()) as f:

    f.send('olleH')
    f.send(None)
    f.send('!dlroW')
    f.send(None)

Prints:

Hello
World!

Another example is iterator, which allows to set source later:

with (repack
        .trim()
        .integer()
        .iterator()) as iterator:

    results = []
    for v in iterator.send(iter(['1 ','\t2', '\n3'])):
        results.append(v)

Results in:

[1, 2, 3]

Or vice versa, using accumulator:

with (repack
        .trim()
        .integer()
        .accumulator()) as acc:

    acc.send('1 ')
    acc.send('\t2')
    acc.send('\n3')

    results = []
    for v in acc:
        results.append(v)

The package is under development. Everyone is welcome to contribute. For TODOs, please see the current TODO list in the root folder.

Requirements

• Python 3.4.2

Install

sudo pip install repack

Extension

As easy as adding more filters to filters/__init__.py or more flows to flows/__init__.py.
