How do I avoid expanding folded regions when I invoke the code formatter?

Question

As you know, Delphi 2010 has built-in code formatting. However, formatting unfolds all folded code blocks. Any ideas how to fix it? This \"feature\" is particularly annoying for

Answer 1

Well, this question is really old, but as it was mentioned here:

How to preserve code folding when formatting source

and there is no answer, I thought I could answer both, here is the answer I posted there:

What you can do is create regions and disable code folding, format code and then reenable the code folding.

To create code regions do:

{$REGION 'Optional text that appears when the code block is folded'} 
// code 
{$ENDREGION}

To toggle code folding option, press Ctrl+Shift K+O.

so, put your code into regions, fold what you want, press Ctrl+Shift K+O to disable the folding, format by pressing Ctrl+D then press Ctrl+Shift K+O again to re enable the folding.

When you re enable the folding, what was folded with a region is going to stay folded.

I hope this helps you.

One way to work around it is to not format the entire file at once, but to select a portion, and format that.

As long as you don't select a region, the expand-state of all regions remains untouched.

Formatting an entire file at once is usually not really a good idea anyway, because the formatter doesn't "understand" what it's doing. I always inspect all changes that it makes, and that's easier when there are no changes outside of the area that's visible.
