RJ TextEd

With a script (look third script is this post) i delete all until the rest of nearly 10 lines from 1100 lines in one step.

With 'Edit -> Undo' (same in 'Edit -> Undo/Redo History...') there only ~100 are restored. The rest is missing !

You should change the size of the undo buffer in settings. It is probably set to 100.

But... Between BeginUndo and EndUndo should it be one single change !? And not > 100

If a script make 10 000 changes in a document - it will create 10 000 undo actions that is stored in memory. I've made a temporary fix that will increase the undo list limit, when running a script.

Adding those 10 000 undo actions as one item to the list would probably be more elegant. And maybe it should be done that way in a later version...

The temporary fix in V10.50 stable isn't the best solution !

While the script and undo now works, the 1000 Delete.Line-commands need < 1s and the undo of the same actions need ~5s !
Possibly the updating of the RJTED-window is the problem (the slider is flicker while undo) !
