DAWG
This package provides DAWG(DAFSA)-based dictionary-like read-only objects for Python (2.x and 3.x).
String data in a DAWG may take 200x less memory than in a standard Python dict and the raw lookup speed is comparable; it also provides fast advanced methods like prefix search.

has_keys_with_prefix(prefix) method (thanks Matt Hickford)

0.7 (2013-04-05)
IntCompletionDAWG
0.6.1 (2013-03-23)
Installation issues in environments with LC_ALL=C are fixed;
PyPy is officially unsupported now (use DAWG-Python with PyPy).
0.6 (2013-03-22)
many thread-safety bugs are fixed (at the cost of slowing library down).
0.5.5 (2013-02-19)
fix installation under PyPy (note: DAWG is slow under PyPy and may have bugs).
0.5.4 (2013-02-14)
small tweaks for docstrings;
the extension is rebuilt using Cython 0.18.
0.5.3 (2013-01-03)
small improvements to .compile_replaces method;
benchmarks for .similar_items method;
the extension is rebuilt with Cython pre-0.18; this made .prefixes and .iterprefixes methods faster (up to 6x in some cases).
0.5.2 (2013-01-02)
tests are included in source distribution;
benchmark results in README was nonrepresentative because of my broken (slow) Python 3.2 install;
installation is fixed under Python 3.x with LC_ALL=C (thanks Jakub Wilk).
0.5.1 (2012-10-11)
better error reporting while building DAWGs;
__contains__ is fixed for keys with zero bytes;
dawg.Error exception class;
building of BytesDAWG and RecordDAWG fails instead of producing incorrect results if some of the keys has unsupported characters.
0.5 (2012-10-08)
The storage scheme of BytesDAWG and RecordDAWG is changed in this release in order to provide the alphabetical ordering of items.
This is a backwards-incompatible release. In order to read BytesDAWG or RecordDAWG created with previous versions of DAWG use payload_separator constructor argument:
>>> BytesDAWG(payload_separator=b'\xff').load('old.dawg')
0.4.1 (2012-10-01)
Segfaults with empty DAWGs are fixed by updating dawgdic to latest svn.
0.4 (2012-09-26)
iterkeys, iteritems and iterprefixes methods (thanks Dan Blanchard).
0.3.2 (2012-09-24)
prefixes method for finding all prefixes of a given key.
0.3.1 (2012-09-20)
bundled dawgdic C++ library is updated to the latest version.
0.3 (2012-09-13)
similar_keys, similar_items and similar_item_values methods for more permissive lookups (they may be useful e.g. for umlaut handling);
load method returns self;
Python 3.3 support.
0.2 (2012-09-08)
Greatly improved memory usage for DAWGs loaded with load method.
There is currently a bug somewhere in a wrapper so DAWGs loaded with read() method or unpickled DAWGs uses 3x-4x memory compared to DAWGs loaded with load() method. load() is fixed in this release but other methods are not.
0.1 (2012-09-08)
Initial release.
