When I try to edit a text file which contains some Chinese words, I see that the wrap word feature is ugly.
See the original view (no wrap enabled)

Now, when wrap word enabled, you can see the long Chinese sentence was treated as a single word, so there will be long empty spaces after the word "efg".


As I see the Scintilla component support "wrap char" feature, I just enabled it, and now it looks better.


The document said in http://www.scintilla.org/ScintillaDoc.html#LineWrapping
Quote
SCI_SETWRAPMODE(int wrapMode)
SCI_GETWRAPMODE
Set wrapMode to SC_WRAP_WORD (1) to enable wrapping on word boundaries, SC_WRAP_CHAR (2) to enable wrapping between any characters, and to SC_WRAP_NONE (0) to disable line wrapping. SC_WRAP_CHAR is preferred to SC_WRAP_WORD for Asian languages where there is no white space between words.

Patch is below:

Calling ed->GetControl() at every line is plain ugly. Please save it in a variable and use it instead.

No, I did not do that. Wrap mode is set once for the whole editor, no need for each lines.

OK, the function name cause confusion. :)
This function is a menu click handler. There was a function named "OnWordWrap", so I add this one named "OnCharWrap".

Hm, it seems that I'm not clear enough.
In the snippet I've posted you have 4 calls to ed->GetControl(), instead of just doing "Control *control=ed->GetControl();" and then just use control.

This is sort of my fault, not just his patch, because the whole plugin is full of ed->GetControl()s. I say "sort of" because ed->GetControl() is a reasonably frequent occurrence throughout the C::B codebase, though in this particularly plugin it's grown to be egregious due to the sheer number of options.

As dmoore said, there are a lot of code like:
Code Select

void EditorTweaks::OnXXXXXXX(wxCommandEvent &/*event*/)
{
   cbEditor* ed = Manager::Get()->GetEditorManager()->GetBuiltinActiveEditor();
   if (!ed || !ed->GetControl() || m_isUpdatingUI)
       return;

   ed->GetControl()->XXXXXX();
   ....
   ed->GetControl()->YYYYYY();
}

Can you give a much better way?
I think we can extract a common code to a member function, like:
Code Select

cbStyledTextCtrl* EditorTweaks::GetSafeControl()
{
   cbEditor* ed = Manager::Get()->GetEditorManager()->GetBuiltinActiveEditor();
   if (!ed || m_isUpdatingUI)
       return nullptr;
   return ed->GetControl();
}


Then in the function body, we can have:
Code Select

void EditorTweaks::OnXXXXXXX(wxCommandEvent &/*event*/)
{
   cbStyledTextCtrl* control = GetSafeControl();
   if (!control || m_isUpdatingUI)
       return;

   control->XXXXXX();
   ....
   control->YYYYYY();
}

Comments?

EDIT: Check the m_isUpdatingUI in the GetSafeControl function?

If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

You can go the EditorTweaks::GetSafeControl() path if you know that you'll use the function a lot.

I'm on the way, thanks.

@dmoore
I have a question:
What does the member variable "m_isUpdatingUI" used for?
I see the only time it was set to true is in the function:

Code Select

void EditorTweaks::UpdateUI()
{
    if (!m_tweakmenu)
    return;

    cbEditor* ed = Manager::Get()->GetEditorManager()->GetBuiltinActiveEditor();
    if (!ed || !ed->GetControl())
    {
        m_tweakmenuitem->Enable(false);
        return;
    }
    m_tweakmenuitem->Enable(true);

    wxMenu *submenu = m_tweakmenu; //_("Editor Tweaks") TODO: Retrieve actual menu

    m_isUpdatingUI = true; // ignore events the following can trigger
    submenu->Check(id_et_WordWrap,ed->GetControl()->GetWrapMode()==wxSCI_WRAP_WORD); // FIXME (ollydbg#1#09/26/13): Dose this Check function cause an menu event handler call?
    submenu->Check(id_et_CharWrap,ed->GetControl()->GetWrapMode()==wxSCI_WRAP_CHAR);
    submenu->Check(id_et_ShowLineNumbers,ed->GetControl()->GetMarginWidth(0)>0);
    submenu->Check(id_et_TabChar,ed->GetControl()->GetUseTabs());
    submenu->Check(id_et_TabIndent,ed->GetControl()->GetTabIndents());
    submenu->Check(id_et_TabSize2,ed->GetControl()->GetTabWidth()==2);
    submenu->Check(id_et_TabSize4,ed->GetControl()->GetTabWidth()==4);
    submenu->Check(id_et_TabSize6,ed->GetControl()->GetTabWidth()==6);
    submenu->Check(id_et_TabSize8,ed->GetControl()->GetTabWidth()==8);
    submenu->Check(id_et_EOLCRLF,ed->GetControl()->GetEOLMode()==wxSCI_EOL_CRLF);
    submenu->Check(id_et_EOLCR,ed->GetControl()->GetEOLMode()==wxSCI_EOL_CR);
    submenu->Check(id_et_EOLLF,ed->GetControl()->GetEOLMode()==wxSCI_EOL_LF);
    submenu->Check(id_et_ShowEOL,ed->GetControl()->GetViewEOL());
    submenu->Check(id_et_SuppressInsertKey, m_suppress_insert);
    submenu->Check(id_et_ConvertBraces,     m_convert_braces);
    m_isUpdatingUI = false; // done
}


But you have many checks in the event function handler, like: ( I have wrap the check in function GetSafeControl())
Code Select

void EditorTweaks::OnCharWrap(wxCommandEvent &/*event*/)
{
    cbStyledTextCtrl* control = GetSafeControl();
    if (!control)
        return;

    bool enabled = control->GetWrapMode() == wxSCI_WRAP_CHAR;

    if (enabled)
        control->SetWrapMode(wxSCI_WRAP_NONE);
    else
        control->SetWrapMode(wxSCI_WRAP_CHAR);
}
....
cbStyledTextCtrl* EditorTweaks::GetSafeControl()
{
    cbEditor* ed = Manager::Get()->GetEditorManager()->GetBuiltinActiveEditor();
    if (!ed || m_isUpdatingUI)
        return nullptr;
    return ed->GetControl();
}


Does this means you have some chance that
Code Select

submenu->Check(id_et_TabChar,ed->GetControl()->GetUseTabs());

will internally call
Code Select

void EditorTweaks::OnCharWrap(wxCommandEvent &/*event*/)

?

In case this does change the status of id_et_TabChar (from check to unchecked or inverse), does this cause some error?
Thanks.

I think that was my reasoning for including that check. Presumably there are nicer ways of handling this.

Does this means you have some chance that
Code Select

submenu->Check(id_et_TabChar,ed->GetControl()->GetUseTabs());

will internally call
Code Select

void EditorTweaks::OnCharWrap(wxCommandEvent &/*event*/)

?

In case this does change the status of id_et_TabChar (from check to unchecked or inverse), does this cause some error?
Thanks.

I think that was my reasoning for including that check. Presumably there are nicer ways of handling this.
From my research of wx's source, I think that manually runing the functions
Code Select
void wxMenuBase::Check( int id, bool enable )
does not cause event handler to be called, so I simply think the member variable m_isUpdatingUI is not needed here.

If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

This is often a problem with GTK so I assumed it would also be a problem with wxGTK. If you are sure it isn't then go ahead and remove it.

Ok, I asked this question on wx forums, and some one give me the reply, Re: wxMenu Check() cause event handler to be called?, now I need some one help to give me the result on Linux. BTW: I do have have a Linux system.

Ping, any one can test this on Linux, thanks.
