======

A collection of useful Python functions.

Feel free to cut and paste into your own projects.

All functions are written to work with Python 2 and 3.

Examples

--------

Contextmanagers tmpdir() and chdir()::

    >>> import os

    >>> from lib import tmpdir, chdir

    >>>

    >>> with tmpdir() as t:

    ...     with chdir(t):

    ...             print(t)

    /tmp/tmpdRzm2V

    ...             print(os.getcwd())

    /tmp/tmpdRzm2V

    ...             os.mkdir('these')

    ...             os.mkdir('temporary')

    ...             os.mkdir('dirs')

    ...             os.mkdir('will')

    ...             os.mkdir('be')

    ...             os.mkdir('deleted')

    ...

    >>>

    >>> os.chdir('/tmp/tmpdRzm2V')

    Traceback (most recent call last):

      File "", line 1, in 

    OSError: [Errno 2] No such file or directory: '/tmp/tmpdRzm2V'

inpipe() and stripped()::

    >>> import os

    >>> from lib import inpipe, stripped

    >>>

    >>> for line in stripped(inpipe(['ls'])):

    ...     print(repr(line))

    ...

    'LICENSE'

    'olelib.py'

    'olelib.pyc'

    'README.rst'

    >>> 

outpipe()::

    >>> from lib import outpipe

    >>> 

    >>> args = ['vorbiscomment', '-w', '-c', '-', '.ogg']

    >>> with outpipe(args, nl=True) as write:

    ...     write('artist=Kepa Junkera')

    ...     write('album=Bilbao 00:00h')

    ...     write('title=Arin Qubec')

    ...     write('tracknumber=1')

    ...    

    

Inpipe and outpipe will encode/decode the data. The default encoding

is 'utf-8', but this can be overriden by calling inpipe(args,

encoding='latin1') etc.

env()::

    >>> from lib import env

    >>>

    >>> env('$USER lives in $HOME')

    'olemb lives in /home/olemb'

    >>>
