So the code folding needs load / save routines to serialize and deserialize.

In progress...

BUG: 56958

Automatic folding (remember folding from last sesion) was implemented

M  +11   -0    part/document/katedocument.cpp
M  +2    -1    ktexteditor/sessionconfiginterface.h

Again open since KDE 4.11: Implement in KateView::read/writeSessionConfig()

Created attachment 87390 [details]
minimal java file

Created attachment 87391 [details]
minimal php file

remembering code folding from previous session does work for some files (e.g php) and not for some others (e.g java) whereas session file contains correct folding informations for both :

[Document 0]
...
FoldedColumns=0,3
FoldedLines=3,7
...
URL=file:///tmp/file.php


[Document 1]
...
FoldedColumns=0,3
FoldedLines=2,6
...
URL=file:///tmp/file.java

Cannot reproduce this difference java/php today.
Still folding info seems to be saved but not loaded.

Qt: 4.8.6
KDE Development Platform: 4.13.1
Kate: 3.13.1

I made a mistake with the version (I use two different ones)
In latest kate (Qt: 4.8.6/KDE Development Platform: 4.13.1/Kate: 3.13.1) code folding information is NOT stored in the session file.
In an earlier 3.11.3 version of kate, code folding information was stored. But not loaded...

building from the latest source and trying to implement the feature 

looks like "TextFolding" info moved in the session file from [Document] to [Viewspace], must have something to do with http://kate-editor.org/2013/03/27/new-text-folding-in-kate-git-master/

but only commas written here for now as "TextFolding=" info in session file

trying to figure out how to output/input the code folding data : "QVariant(QVariantMap, QMap(("endColumn", QVariant(int, 0) ) ( "endLine" ,  QVariant(int, 56) ) ( "flags" ,  QVariant(int, 2) ) ( "startColumn" ,  QVariant(int, 1) ) ( "startLine" ,  QVariant(int, 46) ) )  )"

data successfully saved/loaded as list "TextFolding=1420,1,1425,1,2" (start line, start column, end line, end column, flags)

code folding state seems functionnal again (maybe more tests needed)

Cool, Phil! Can you post a diff of you patch (git diff on the command line) on reviewboard.kde.org ? This is the standard way to do a review request in KDE/Kate. Thanks!

done

...as I wrote Christoph a few years ago: 
For me it would be enough to fold all stuff in the same level using mouse_right or mouse_middle. So a class would look before/after folding:

class foo{
  function foo_1(){
     ...
  }
  function foo_2(){
     ...
  }
  function foo_3(){
     ...
  }
}

class foo{
  function foo_1(){
  function foo_2(){
  function foo_3(){
}

This should not be so hard to program and it would also make files, that never had been opend by kate before, easy to handle.
