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 works in Enchant

1 add hyphenation function in Enchant
what I have done:
Firstly, I add hyphenation module in Enchant:
================about the code===========
I think we can combine the hyphenation with spell-checking together.
so that we can make the code more flexsible.
In my opinion, we can make code like this:
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);

===================== 1
In order to achieve this, we need to add  hyphenation function in
EnchantDict. something like:
char **(*hyphenate) (struct str_enchant_dict * me,
                          const char *const word, size_t len,
                          size_t * out_n_suggs);

======================== 2
and 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
 finally, we set the connetion

 dict->hyphenate = ispell_dict_hyphenate;
 dict->suggest = hspell_dict_hyphenate;
dict->suggest = zemberek_dict_hyphenate;

2 add five backends to support hyphenation
  including ispell, myspell, zemberek, voikko, uspell

we all know that Enchant has eight types of backend to support multi-language.
USpell
HSpell
ASpell
MySpell....

but I found that in Abiword. we only use two backends:
libenchant_ispell.dll  libenchant_myspell.dll

another surprising thing is that in the dictionary\ispell I can only
find one dic: american.hash(En_US)
and the hunspell dic is empty~~


the changes:
1 deleted the unneed connection, such as HSpell
2 add hunspell(myspell) hyphenation code
3 implement hyphenation using hunspell
4 implement hyphenation using Zemberek

================1 deleted the unneed connection, such as HSpell===========
Hebrew dont need any hyphenation
Yiddish dont need any hyphenation

====================2  implement hyphenation using hunspell
added 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

need more tests

==================== 3 implement hyphenation using Zemberek
 just using dbus_g_proxy_call:

 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;
}


The attachment is the updated version today. Now we have four backends
of hyphenantion
1 hunspell: using seperated dic: such as hyph_en_us.dic.
  we can download dic from internet
2 libhyphenaiton: the dic is provided by author, sometimes limited
3 zemberek: for Turkis
4 Voikko: for Finnish


3 the depot of enchant
I just copy the bulid result of enchant:
enchant\bin\Debug\libenchant_myspell.dll ---->
abiword\msvc2008\Debug\lib\enchant\libenchant_myspell.dll
enchant\bin\Debug\libenchant_ispell.dll ---->
abiword\msvc2008\Debug\lib\enchant\libenchant_ispell.dll
enchant\bin\Debug\libenchant.dll ---->abiword\msvc2008\Debug\bin\ibenchant.dll

3 the implementation of the five backends
4 call hyphenation module of enchant to display the hyphenation-result
in abiword
5 after user's operation, refresh the hyphenation-result accordingly
  include user adding new word, delete word, copy word, cut word


6 test in Linux
todo:
1 Fully support hyphenation in Abiword
2 Support more language besides En_us
3 Some tests in Linux(Unix)


Still to improve:
1 code re-factor
2 deal with more language
3 include more user's operation(such as operate with picture may
influence the hyphenation result)

the summary about What I have done in GSoc2011

my works in GSoc2011 including two parts.
1 the hyphenation module in Enchant
 Key: to reuse the abstract layer of Enchant and add Hyphenation function
         we can add more language easy
         Deal with more languages




2  call in Abiword. including:
   split run
   find split info
   deal with user's operation

new version, but a lot of question~confusing

Hi, All.

I am working on GSoc Abiword this summer to implement the hyphenation support in Abiword. Before I implement the function, I find some code  in Abiword for spell-checking. so I follow the code to implement hyphenation function using enchant. And I have some questiones about enchant. thanks

I want to use enchant to implement hyphenation to keep the dictionary seperately.

 

the attachment1 is the main class diagram

the attachment2 is the code I implement the hyphenation follow spell-checking code

 

 

My question is:

1. Is there some funcition for hyphenation like enchant_dict_hyphenate in Enchant? 

2. how the enchant achieve the function? I can track in the code in enchant~

3. give some suggestion to me about my codes, thanks

 

 

 

Thanks very much~

Start coding about Hyphenation in ABiword now. One week I can make it a preliminary result~~~

wait for me~

patch file_Implement progress bar in windows

The patch file I have modified in the following spaces, to keep same with the source code:
==================1 ap_usb_ProgressListener======
create a class to deal with ProgressListener(the same as the gtk code). seperate from the statusBarListener
class ap_usb_ProgressListener : public AP_StatusBarFieldListener
{
public:
.............
virtual void notify();   //deal with progressbar update
protected:
HWND m_ProgressWND;
};
==================2======
and in the notify function deal with the update:   and i find the place to add pulse process bar
void ap_usb_ProgressListener::notify()
{  
if(pProgress->isDefinate())
{
double fraction = pProgress->getFraction();
SendMessage(m_ProgressWND,PBM_SETPOS,fraction*100,0);
}
else
{   //here pulse process bar  <--------------pulse process bar
}
}
===========================3============
In this situation, I need to build the connection between ap_usb_ProgressListener and ProcessBar in the createWindow()    in this place, your code have one error(the elseif is in the wrong place)
else if(pf->getFillMethod() == PROGRESS_BAR)
{
pf->setListener((AP_StatusBarFieldListener *)(new ap_usb_ProgressListener(pf, m_hwndProgressBar)));
}
===========================4============
Remove unused function and variables
