Raw Blame History

- fix library versioning
- improved manual
2011-02-02: Hunspell 1.3.1 release:
- bug fixes
2011-01-26: Hunspell 1.2.15/1.3 release:
- new features: MAXDIFF, ONLYMAXDIFF, MAXCPDSUGS, FORBIDWARN, see manual
- bug fixes
2011-01-21:
- new features: FORCEUCASE and WARN, see manual
- new options: -r to filter potential mistakes (rare words
signed by flag WARN in the dictionary)
- limited and optimized suggestions
2011-01-06: Hunspell 1.2.14 release:
- bug fix
2011-01-03: Hunspell 1.2.13 release:
- bug fixes
- improved compound handling and
other improvements supported by OpenTaal Foundation, Netherlands
2010-07-15: Hunspell 1.2.12 release
2010-05-06: Hunspell 1.2.11 release:
- Maintenance release bug fixes
2010-04-30: Hunspell 1.2.10 release:
- Maintenance release bug fixes
2010-03-03: Hunspell 1.2.9 release:
- Maintenance release bug fixes and warnings
- MAP support for composed characters or character sequences
2008-11-01: Hunspell 1.2.8 release:
- Default BREAK feature and better hyphenated word suggestion to accept
and fix (compound) words with hyphen characters by spell checker
instead of by work breaking code of OpenOffice.org. With this feature
it's possible to accept hyphenated compound words, such as "scot-free",
where "scot" is not a correct English word.
- ICONV & OCONV: input and output conversion tables for optional character
handling or using special inner format. Example:
# Accepting de facto replacements of the Romanian comma acuted letters
SET UTF-8
ICONV 4
ICONV ş ș
ICONV ţ ț
ICONV Ş Ș
ICONV Ţ Ț
Typical usage of ICONV/OCONV is to manage an inner format for a segmental
writing system, like the Ethiopic script of the Amharic language.
- Extended CHECKCOMPOUNDPATTERN to handle conpound word alternations, like
sandhi feature of Telugu and other writing systems.
- SIMPLIFIEDTRIPLE compound word feature: allow simplified Swedish and
Norwegian compound word forms, like tillåta (till|låta) and
bussjåfør (buss|sjåfør)
- wordforms: word generator script for dictionary developers (Hunspell
version of unmunch).
- bug fixes
2008-08-15: Hunspell 1.2.7 release:
- FULLSTRIP: new option for affix handling. With FULLSTRIP, affix rules can
strip full words, not only one less characters.
- COMPOUNDRULE works with all flag types. (COMPOUNDRULE is for pattern
matching. For example, en_US dictionary of OpenOffice.org uses COMPOUNDRULE
for ordinal number recognition: 1st, 2nd, 11th, 12th, 22nd, 112th, 1000122nd
etc.).
- optimized suggestions:
- modified 1-character distance suggestion algorithms: search a TRY character
in all position instead of all TRY characters in a character position
(it can give more readable suggestion order, also better suggestions
in the first positions, when TRY characters are sorted by frequency.)
For example, suggestions for "moze":
ooze, doze, Roze, maze, more etc. (Hunspell 1.2.6),
maze, more, mote, ooze, mole etc. (Hunspell 1.2.7).
- extended compound word checking for better COMPOUNDRULE related
suggestions, for example English ordinal numbers: 121323th -> 121323rd
(it needs also a th->rd REP definition).
- bug fixes

iconv support in stemming and morphological analysis of the Hunspell

2008-04-12: Hunspell 1.2.2 release:
- extended dictionary (dic file) support to use multiple base and
special dictionaries.

-m: morphological analysis or flag debug mode (without affix
rule data it signs the flag of the affix rules)

suggestion for languages with a lot of affixes.
--------------- end of examples --------------------

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).
