source insight中文显示和处理

浏览网页的时候突然看到一篇介绍关于source insight中文显示修正的方法，感觉非常好，也比较全面，于是在自己的source insight中又重新设置了一下。

1、首先设置中文的显示，使中文能像英文或中文在vc中的显示一样比较紧凑，便于浏览，不过在进行实际的设置前说先要做一下说明：在代码中使用中文较多的主要有两个地方一个是函数或语句前的“/**/“注释，另一个就是语句右面的“//”注释。因此为了尽量的减少对配置的修改，我们只需要对这两处稍作修改就行了：

”/**/“修改（把文字改为中文字体，斜体关掉），选项-->样式属性：

”//“修改（把字体选为中文，斜体关闭），选项-->样式属性：

基本上来说，修改了这两处后我们所使用的中文就可以正常显示了，如果那里还存在问题，基本上都可以同样的方式进行修改。

不过做到这里只是能是中文正常显示了，但是左移光标、右移光标、左选一个字、右选一个字、回退和删除等却只能对汉字进行半个字的操作，因此还需要进一步处理，使之操作类似如下：

a、打开base项目中的utils.em文件，添加如下代码：

macro SuperBackspace()
{
    hwnd = GetCurrentWnd();
    hbuf = GetCurrentBuf();

    ipos = GetWndSelIchFirst(hwnd);
    // get current line number
    ln = GetBufLnCur(hbuf);
    if ((GetBufSelText(hbuf) != "") || (GetWndSelLnFirst(hwnd) != GetWndSelLnLast(hwnd))) {
        // sth. was selected, del selection
        SetBufSelText(hbuf, " ");  // stupid & buggy sourceinsight 
        // del the " "
        SuperBackspace(1);
        stop;
    }

            if ((count / 2 * 2 != count) && (ipos < len))
                ipos = ipos + 1;    // adjust cursor position

保存后，打开选项-->键分配，将新添加的宏依次与相应按键绑定，需要绑定的宏如下：

  Marco: SuperBackspace绑定到BackSpace键；
  Marco: SuperCursorLeft绑定到<-键，
  Marco: SuperCursorRight绑定到->键，
  Marco: SuperShiftCursorLeft绑定到Shift+<-，
  Macro: SuperShiftCursorRight绑定到shift+->，
  Macro: SuperDelete绑定到del。

过程结束后重新打开source insight打开新的项目，就可以对里面的中文进行正常的操作了。
