memory debugging of all tests with a simple command:
VALGRIND=memcheck make check
* lots of other improvements and bug fixes (see ChangeLog)
2005-08-26: Hunspell 1.0.9 release
* improved related character map suggestion
* improved ngram suggestion
------ examples for ngram improvement (O=old, N = new ngram suggestions) --
1. Permenant (instead of Permanent)
O: Endangerment, Ferment, Fermented, Deferment's, Empowerment,
Ferment's, Ferments, Fermenting, Countermen, Weathermen
N: Permanent, Supermen, Preferment
Note: Ngram suggestions was case sensitive.
2. permenant (instead of permanent)
O: supermen, newspapermen, empowerment, endangerment, preferments,
preferment, permanent, preferment's, permanently, impermanent
N: permanent, supermen, preferment
Note: new suggestions are also weighted with longest common subsequence,
first letter and common character positions
3. pernemant (instead of permanent)
O: pimpernel's, pimpernel, pimpernels, permanently, permanents, permanent,
supernatant, impermanent, semipermanent, impermanently
N: permanent, supernatant, pimpernel
Note: new method also prefers root word instead of not
relevant affixes ('s, s and ly)
4. pernament (instead of permanent)
O: tournaments, tournament, ornaments, ornament's, ornamenting, ornamented,
ornament, ornamentals, ornamental, ornamentally
N: ornamental, ornament, tournament
Note: Both ngram methods misses here.
5. obvus (instad of obvious):
O: obvious, Corvus, obverse, obviously, Jacobus, obtuser, obtuse,
obviates, obviate, Travus
N: obvious, obtuse, obverse
Note: new method also prefers common first letters.
6. unambigus (instead of unambiguous)
O: unambiguous, unambiguity, unambiguously, ambiguously, ambiguous,
unambitious, ambiguities, ambiguousness
N: unambiguous, unambiguity, unambitious
7. consecvence (instead of consequence)
O: consecutive, consecutively, consecutiveness, nonconsecutive, consequence,
consecutiveness's, convenience's, consistences, consistence
N: consequence, consecutive, consecrates
An example in a language with rich morphology:
8. Misisipiben (instead of Mississippiben [`in Mississippi' in Hungarian]):
O: Misikédéiben, Pisisedéiben, Misikéiéiben, Pisisekéiben, Misikéiben,
Misikéidéiben, Misikékéiben, Misikéikéiben, Misikéiméiben, Mississippiiben
N: Mississippiben, Mississippiiben, Misiiben
Note: Suggesting not relevant affixes was the biggest fault in ngram
suggestion for languages with a lot of affixes.
--------------- end of examples --------------------
* support twofold prefix cutting
* lots of other improvements and bug fixes (see ChangeLog)
* test Hunspell with 54 OpenOffice.org dictionaries:

In en_AU dictionary, there is an abbrevation with two dots (`eqn..'), but
`eqn.' is missing. Presumably it is a dictionary bug. Myspell also
haven't accepted it.
Hungarian dictionary contains pseudoroots and forbidden words.
Unmunch haven't supported these features yet, and generates bad words, too.
* check affix rules and OOo dictionaries. Detected bugs in cs_CZ,
es_ES, es_NEW, es_MX, lt_LT, nn_NO, pt_PT, ro_RO, sk_SK and sv_SE dictionaries).
