otherstuf 0.651

Attributes-accessible mappings chainstuf (like ChainMap) & counterstuf (like Counter)

Attribute-accesible collections inspired by stuf. Implements chainstuf and counterstuf: versions of ChainMap and Counter that expose their keys as attributes.

The ultimate goal of this module is to have these functions available in the stuf module, and this sidecar to be retired.

Usage

Use these just like you would ChainMap and Counter, except that you get attribute-style access as well.

For chainstuf:

from chainstuf import chainstuf

d1 = dict(this=1, that=2)
d2 = dict(roger=99, that=100)

# test simple attribute equivalence
c = chainstuf(d1, d2)

assert c.this == 1
assert c.roger == 99

c.roger = 'wilco'
assert c.roger
print "roger", c.roger

d1.update(feeling='fancypants!')
print "i'm feeling", c.feeling     # passed through, since d2 lacks 'feeling'

For counterstuf:

from counterstuf import counterstuf

c = counterstuf()
c.update("this and this is this but that isn't this".split())
c.total = sum(c.values())

print "everything:", c.total
print "'this' mentioned", c.this, "times"
print "'bozo' mentioned", c.bozo, "times"
print c

NB counterstuf does not yet function under Python 2.6, since it does not have a collections.Counter. It doesn’t have a ChainMap, either, but we have a workaround for that (piggyback stuf.ChainMap). Will have to acquire a suitable Counter workaround for 2.6.

Notes

• Commenced automated multi-version testing with pytest and tox.

• Now successfully packaged for, and tested against, Python 2.6, 2.7, 3.2, and 3.3. (With the exception of counterstuf under 2.6, as described above.)

• The author, Jonathan Eunice or @jeunice on Twitter welcomes your comments and suggestions.

Installation

pip install otherstuf

To easy_install under a specific Python version (3.3 in this example):

python3.3 -m easy_install otherstuf

(You may need to prefix these with “sudo “ to authorize installation.)
