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.

Changes
0.7.1 (2013-05-25)
- Extension is rebuilt with Cython 0.19.1;
- fixed segfault that happened on lookup from incorrectly loaded DAWG (thanks Alex Moiseenko).
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.
