Subject Re: whitespace cleanup and efficiency drive
Date Wed, 12 Nov 2003 01:21:33 GMT
The result of this thread: let's care only about white spaces.

It's my opinion too. But the editor should do this automatically, not by 
running a task by hand. IDEA does it pretty good: Removes trailing 
spaces when saving a file, replaces existing tabs with spaces on save, 
when using the key TAB it adds spaces to the file. But unfortunately 
IDEA is not for free.

The editors I use at the moment are Eclipse and jEdit. Both can insert 
spaces instead of TAB when using the key. But both do not handle the 
other two things. And even worse for XML with Eclipse and SunBow: it 
does not even handle the TAB => spaces issue.

Even if this leads not to additional results my conclusion:
Having the right tools we would not have such problems.
