The code folding for Clipper has been implemented and the new xFolder.dll can be found here:

http://www.zeusedit.com/z300/xfolder.zip

To install the new dll make a backup copy of the current xFolder.dll file, located in the Zeus installation directory and replace it with one from the zip file above.

You will also need to create a new Clipper Document Type and enable the Display line folds margin option.

There is one issue with this new folder. The .h extension is used by the c/c++ folder so naturally any clipper .h files will be folded incorrectly using the c/c++ folder

If you find any other problems with this new dll just post a reply to this topic.

It works. Thanks

How easy is it for the end user to add items to these?

I'd like to see class/endclass, method/return, static/return, function/return

The folding is easy enough to change but at present it is hard coded into the folding dll, so the changes are not user configurable

But I am more than happy add your changes to the current folding dll so watch this space for a new dll coming soon

But I do have a question. The class/endclass is straight forward enough as is the method/return and I think the function/return is already in the folder dll. But I don't understand the static/return case

I did a bit of a search and found this link:

http://www.clipx/ng/clguide/ngbbed3.php

This page seems to suggest the static is an optional qualifier for a function, so would not this fold already be covered by by the function/return case

The above changes (other than the static change) have been made and the new xFolder.dll can be found here:

http://www.zeusedit.com/z300/xfolder.zip

To install the new dll make a backup copy of the current xFolder.dll file, located in the Zeus installation directory and replace it with one from the zip file above.

Thanks, I'll try it out.

I'll check on the static part as well

Hi,

It seems there's a problem with the class/endclass collapse. Clicking on the - next to class collapses the whole file.

But a few things to release is when any start of fold folds up the entire file it means that the number of start folds does not match the number of end folds.

So the folding might in fact be working, or alternatively your coding style might have confused the folding logic.

Could you please post a short snippet of sample code that highlights this problem.

Cheers Jussi
PS: The folder also has a Lines Containing Multiple End of Fold Markers limitation.

Hi,

Sample below

CLASS MyClass

DATA cTitle

Method New Constructor
Method Activate

ENDCLASS
//--------------------------------
Method New() CLASS MyClass

::cTitle := "My class"

return self
//--------------------------------
Method Activate

// Do something

return nil
//--------------------------------

This sample code definitely highlights a few problems.

For example the definition of the Method New Constructor within the class is identical to implementation of that method, so naturally they both look like start of folds, where in fact only the later is a fold

Similarly the CLASS MyClass definition text is also found in the implementation of the method and hence both these lines look like fold points, where in fact only the former line is a fold

So the folder in it's current state will definitely not work

Unless there is a way to distinguish the real fold points from the other non-fold points the folding can not possibly work.

The only way I can see that the two can be distinguished is the fact that the real folds will more likely than not occur at the start of line. Is this a valid assumption for most xBase code

So the new xfolder.dll implements this rule and provided the class, function, method and procedure are at the start of line the folding seems to now work fine.

That's perfect, thanks.
