-Until now, my works in GSoc2011 including four parts as following:
-*1*．*Hyphenation module in Enchant***
-Ø  Read and get totally understand the source code of Enchant
-Ø  Reuse the abstract layer of Enchant and add Hyphenation function in Enchant, so that we can add more language easily
-Ø  Deal with more languages
-Ø  Add five backend implementation, including ispell, myspell, zemberek, voikko, uspell
-Ø  Deal with the spelling-checking module
-*2**．**Call the Hyphenation function in Abiword. *
-Ø  Find split info using enchant_dict_hyphenate
-Ø  Split Text_Run to split word pass the line width and keep their format
-Ø  Deal with user's operation(select, delete, cut, paste)
-Ø  User can select weather to enable the hyphenation function
-*3. Simple Implementation of Chinese Spell-Checking in Enchant*
-Ø  Add a simple spell-check framework for Chinese in Enchant
-Ø  Add library to support
-Ø  Some survey about Chinese Spell-checking
-*4. Code Re-factor and debug*
-Ø  Code Re-factor, include keep the code flexible
-Ø  Debug coding problem
-*5. User interface to manage hyphenation*
-Ø  Windows, Linux, and Cocoa
-*6. How to Support more languages*
-Ø  How to support more languages in ISpell
-Ø  How to support more languages in mySepll
-*7. How to extend the enchant function*
-The detail things:
-h2. [1 Hyphenation module in Enchant|]
-h3. [1.1 Add hyphenation function in Enchant|]
-Firstly, I add hyphenation method in Enchant:
-================the code===========
-I think we can combine the hyphenation with spell-checking together, So that we can make the code more flexible. In my opinion, the hyphenation function defines as following:
-*EnchantDict* enchant_broker_request_dict (EnchantBroker* broker, const***
-*char *const lang); //same as spell-checking***
-*char *enchant_dict_hyphenate(EnchantDict *dict, const char *const word,size_t len);*
-In order to achieve the function and implement in abstract layer, we need to add hyphenation function in EnchantDict. something like, just as a function pointer:
-*char* (*hyphenate) (struct str_enchant_dict * me,*
-*                          const char *const word, size_t len,*
-*                          size_t * out_n_suggs);*
-and the function is implement by the backend. Take “ispell” as example:
-*static char * ispell_dict_hyphenate (EnchantDict * me, const char *const word,*
-*                    size_t len, size_t * out_n_suggs)*
-*{*
-*       ISpellChecker * checker;*
-*       checker = (ISpellChecker *) me->user_data;*
-*       return checker->hyphenate (word, len, out_n_suggs);*
-*}*
-Finally, we set the connetion
-*dict->hyphenate = ispell_dict_hyphenate;*
-* dict->suggest = hspell_dict_hyphenate;*
-*dict->suggest = zemberek_dict_hyphenate;*
-h3. [1.2 Add five backends to support hyphenation|]
-including ispell, myspell, zemberek, voikko, uspell
-Ø  *Hunspell: using seperated dictionary: such as hyph_en_us.dic.  we can download dic from internet***
-Ø  *Libhyphenaiton: the dictionary is provided by author, sometimes limited***
-Ø  *Zemberek: for Turkis***
-Ø  *Voikko: for Finnish***
-the changes:
-deleted the unneed connection, such as HSpell
-add hunspell(myspell) hyphenation code
-implement hyphenation using hunspell
-implement hyphenation using Zemberek
-======1 deleted the unneed connection, such as HSpell===========
-Hebrew don’t need any hyphenation
-Yiddish don’t need any hyphenation
-=======2 Implement hyphenation using hunspell
-In order to use libhyphenation. We need to add files:
-*hyphen/hnjalloc.h***
-*hyphen/hnjalloc.c***
-*hyphen/hyph_en_US.dic***
-*hyphen/hyphen.c***
-*hyphen/hyphen.gyp***
-*hyphen/hyphen.h***
-*hyphen/hyphen.patch***
-*hyphen/hyphen.tex***
-========3 Implement hyphenation using Zemberek
-just using dbus_g_proxy_call the same as Spell-Check in Zemberek:
-the hyphenation is as following
-* char* Zemberek::hyphenate(const char* word)***
-*{***
-*       char* result;***
-*       GError *Error = NULL;***
-*       if (!dbus_g_proxy_call (proxy, "hecele", &Error,***
-*               G_TYPE_STRING,word,G_TYPE_INVALID,***
-*               G_TYPE_STRV, &result,G_TYPE_INVALID)) {***
-*                       g_error_free (Error);***
-*                       return NULL;***
-*       }***
-*       char*result=0;***
-*       return result;***
-*}***
-h3. [1.3 ISpell|]
-I used Libhyphenation in ISpell. The simple code is just like this:
-*static char **
-*ispell_dict_hyphenate (EnchantDict * me, const char *const word)*
-*{*
-*       ISpellChecker * checker;*
-* *
-*       checker = (ISpellChecker *) me->user_data;*
-*       if(me->tag!="")*
-*         return checker->hyphenate (word,me->tag);*
-*    return checker->hyphenate (word,"en_us");*
-*}*
-*The concrete code in ISpellChecker is :*
-*char **
-*ISpellChecker::hyphenate(const char * const utf8Word, const char *const tag)*
-*{  //we must choose the right language tag*
-*       char* param_value = enchant_broker_get_param (m_broker, "enchant.ispell.hyphenation.dictionary.path");*
-*       if(languageMap[tag]!="")*
-*       {*
-*              string result=Hyphenator(RFC_3066::Language(languageMap[tag]),param_value).hyphenate(utf8Word).c_str();*
-* *
-*              char* temp=new char[result.length()];*
-*              strcpy(temp,result.c_str());*
-*              return temp;*
-*       }*
-*       return NULL;*
-*}*
-h3. [1.4 MySpell|]
-I used Libhyphenate in ISpell. The simple code is just like this:
-*char**
-*MySpellChecker::hyphenate (const char* const word, size_t len,char* tag)*
-*{*
-*       if(len==-1) len=strlen(word);*
-*       if (len > MAXWORDLEN *
-*              || !g_iconv_is_valid(m_translate_in)*
-*              || !g_iconv_is_valid(m_translate_out))*
-*              return 0;*
-*       char* result=0;*
-*       myspell->hyphenate(word,result,tag);*
-*       return result;*
-*}*
-*The concrete code in MySpellChecker is :*
-*void Hunspell::hyphenate( const char* const word, char* result, char* tag )*
-*{*
-*       HyphenDict *dict;    *
-*       char buf[BUFSIZE + 1];  *
-*       char *hyphens=new char[BUFSIZE + 1]; *
-*       char ** rep;*
-*       int * pos;*
-*       int * cut;*
-*       /* load the hyphenation dictionary */  *
-*       string filePath="hyph_";*
-*       filePath+=tag;*
-*       filePath+=".dic";*
-*       if ((dict = hnj_hyphen_load(filePath.c_str())) == NULL) {*
-*              fprintf(stderr, "Couldn't find file %s\n",tag);*
-*              fflush(stderr);*
-*              exit(1);*
-*       }*
-*     int len=strlen(word);*
-*     if (hnj_hyphen_hyphenate2(dict, word, len-1, hyphens, NULL, &rep, &pos, &cut)) {*
-*                            free(hyphens);*
-*                            fprintf(stderr, "hyphenation error\n");*
-*                            exit(1);*
-*              }*
-* *
-*       hnj_hyphen_free(dict);*
-*       result=hyphens;       *
-*}*
-h3. [1.5 zemberek|]
-The way in Zemberek is same with the two above:

-h2. [3 Simple Implementation of Chinese Spell-Check in Enchant|]
-After GSoc2011, I would like to add Chinese Spell-Check in Enchant. Chinese Spell-Check is also a very important issue in Word-Processor. I found some lib to support; I just build a simple framework since time is limit.
-The main function:
-h2. [4 Code Re-factor and debug|]
-I have finish the code re-factor both in Enchant and Abiword. Code Re-factor works:
-deal with some ugly code
-deal with the exception
-h2. [5. |]User interface to manage hyphenation
-Doing now, user can enable or disable hyphenation function in user interface (GUI).
-Ø  I have finished GUI in Windows, Linux, and Cocoa.
-Ø  Most languages have been translated for the globalization.
-Take Windows GUI for example, user can check the checkbox for enable or disable hyphenation function.
-Linux and Cocoa need more tests.
-h2. [6. |]How to Support more languages
-As mentioned before, we use Enchant to support more languages. So we have five backend to support more language. Take ISpell and mySpell for example.
-In the folder “abiword\msvc2008\Debug\” there are the folder for hyphenation: Spell and mySpell. And there is two folder for their dictionary.
-h3. [6.1|] How to support more languages in ISpell
-Go into the ISpell, you will see the folder language; you can just copy your languages’ hyphenation dictionary into it. So that our abiword will support your language’s hyphenation.
-Now we support de, en, es, and fr.
-h3. [6.2|] How to support more languages in mySepll
-The same as ISpell, to support more languages in mySpell, we can refer to the myspell folder.
-h2. [7. How to extend the enchant function|]
-I have read much codes in enchant. So I think enchant is a very useful framework for you to support dictionary-need function, such as spell-check, hyphenation. To extend the function in Enchant, we need to do the following things:
-*1 In order to achieve this, we need to add concreate function in EnchantDict firstly. Something like:*
-char **(*hyphenate) (struct str_enchant_dict * me,
-const char *const word, size_t len,
-size_t * out_n_suggs);
-*2 the function is implement by the backend.*
-static char **
-ispell_dict_hyphenate (EnchantDict * me, const char *const word,
-size_t len, size_t * out_n_suggs)
-{
-ISpellChecker * checker;
-checker = (ISpellChecker *) me->user_data;
-return checker->hyphenate (word, len, out_n_suggs);
-}
-*3 we set the connetion with dic*
-dict->hyphenate = ispell_dict_hyphenate;
-dict->suggest = hspell_dict_hyphenate;
-dict->suggest = zemberek_dict_hyphenate;
