我如何调试Squeak源代码？(How do I debug Squeak source code?)

 以下是Squeak 4.1中的划分方法：  
/t1
| t2 |
t1 isInteger
    ifTrue: [t2 := self digitDiv: t1 abs neg: self negative ~~ t1 negative.
        (t2 at: 2)
                = 0
            ifTrue: [^ (t2 at: 1) normalize].
        ^ (Fraction numerator: self denominator: t1) reduced].
^ t1 adaptToInteger: self andSend: #/
 
 我不明白代码。 你能给我一些关于如何调试代码的提示，所以我可以跟踪代码行为吗？ 就像打开一个工作区，键入4/3，我可以检查到Fraction。 有自己的对象，分子，分母等。我怎么能进入4/3，看看Smalltalk如何实现分割？ 

Here is the division method in Squeak 4.1: 
/t1
| t2 |
t1 isInteger
    ifTrue: [t2 := self digitDiv: t1 abs neg: self negative ~~ t1 negative.
        (t2 at: 2)
                = 0
            ifTrue: [^ (t2 at: 1) normalize].
        ^ (Fraction numerator: self denominator: t1) reduced].
^ t1 adaptToInteger: self andSend: #/
 
I do not understand the code. Can you give me some hints on how to debug the code, so I can trace the code behavior? Like open a workspace, type 4/3, I can inspect into Fraction. There are objects self, numerator, denominator and etc. How can I step into 4/3, and see how Smalltalk implemented division?

 我能够使它在chrome中工作。 我做的是我使用\_layouts\15\CORE.js和\_layouts\15\INIT.js  
<div ctxname="ctx1" app="ms-word">
    <a id="OfficeUrl" onclick="g_varSkipRefreshOnFocus = 0;fromOffice = true;if(isIE){window.onfocus = RefreshOnFocus;browseris.ie=true;}DispEx(this, event, 'TRUE', 'FALSE', 'FALSE', 'SharePoint.OpenDocuments.3', '1', 'SharePoint.OpenDocuments', '', '', $('[id$=CheckedOutUserHidden]').val(), $('[id$=UserIdHidden]').val(), '0', '0', '0x7fffffffffffffff', '', '');if(!isIE){window.onfocus = RefreshOnFocus;}g_varSkipRefreshOnFocus = 0;return false;" href="" style="display: none;"></a>
</div>
 
 希望它可以帮到某人 

 我现在需要知道如何为firefox做这个（看起来像sharepoint不支持它？因为它不能从sharepoint打开）。 

I was able to make it work in chrome. What I did is that I used the \_layouts\15\CORE.js and \_layouts\15\INIT.js and I surrounded the a tag with  
<div ctxname="ctx1" app="ms-word">
    <a id="OfficeUrl" onclick="g_varSkipRefreshOnFocus = 0;fromOffice = true;if(isIE){window.onfocus = RefreshOnFocus;browseris.ie=true;}DispEx(this, event, 'TRUE', 'FALSE', 'FALSE', 'SharePoint.OpenDocuments.3', '1', 'SharePoint.OpenDocuments', '', '', $('[id$=CheckedOutUserHidden]').val(), $('[id$=UserIdHidden]').val(), '0', '0', '0x7fffffffffffffff', '', '');if(!isIE){window.onfocus = RefreshOnFocus;}g_varSkipRefreshOnFocus = 0;return false;" href="" style="display: none;"></a>
</div>
 
Hope it helps someone

 I now need to know how to do it for firefox (looks like sharepoint does not support it? because it does not open from sharepoint).
