Custom folding in text mode (addFold, session,unfold)

[Fogel]

Hi guys,

For a build system application we created a logviewer and we are using it to display our build logs and so far everything work perfectly.

Now I'm trying to implement a feature that fold part of the log depending the section a user wants to look into.

I can easily addFold to the editor session :

 for (var i = 0; i < value.Sections.Section.length; i++) {

                            var rangeFold = new range(parseInt(value.Sections.Section[i].LineNumber), 0, parseInt(value.Sections.Section[i].LineNumber) + parseInt(value.Sections.Section[i].Length), Infinity);

                            ace.edit("editor").getSession().addFold(value.Name, rangeFold);

 }

And the code is folded but when I unfold, the log  I can't fold it back and it seem the folddata disapear from the session.

In the end all the custom folding I'm adding , I would like it to be persistent much like  when fold/unfolding comment in any programming language. (having the +/- on the margin , to fold/unfold)

I'm getting a bit frustrasted trying to figure this out so how I would do that ?

Any help would be appreciated.

thank you very much.

you need to implement cusotm folding with getFoldWidget method see  https://github.com/ajaxorg/ace/blob/master/lib/ace/mode/folding/cstyle.js#L75

Ok I see thank you, once I implement my custom folding mode.

How do I use it ? Call this.$setFolding with it ?

either call setFolding or if you have a custom mode set foldingRules property on it similar to https://github.com/ajaxorg/ace/blob/master/lib/ace/mode/javascript.js#L48

probably you are returning invalid range object, i can't know what exactly you are doing wrong without seeing your code.
