Screencast too large for bugs.kde.org Can be found here: http://imageshack.us/clip/my-videos/232/81uaydhtyyqpiyudruyfco.mp4/ Wow, that is quite a nice bug report! If all of them were like this, it would almost be a pleasure to fix bugs ;) I've tried it out now, but I couldn't experience any noticeable lag. Could you try out the latest KatePart/Okular as well and check whether that helps? http://kate-editor.org/get-it/ For KatePart, you would have to "mix" the installation instructions described above with the ones on the Kile wiki (for testing live preview). Alternatively, we could only trigger a sync whenever the line of the cursor changes. Currently, this is done on every key stroke, and this might make everything less responsive. I feel honoured ^^ Michel Ludwig wrote: "Alternatively, we could only trigger a sync whenever the line of the cursor changes. Currently, this is done on every key stroke, and this might make everything less responsive." Is this a suggestion or is it already implemented? But that might do the trick. Synctex anyway only works for paragraphs, doesn't it? I will compile when I have time and see if it makes any difference. (In reply to comment #3) > Is this a suggestion or is it already implemented?

If I remember correctly, Synctex would even work for line + column cursor positions, but OkularPart only considers the lines at the moment. Git commit 8346295484bd489f752593c171f1a15c47d02053 by Michel Ludwig. Committed on 18/09/2012 at 21:58. Pushed by mludwig into branch 'master'. Only synchronize the cursor position when the cursor line has changed This only applies to actual changes in the cursor position and not when re-synchronizing after a compilation, for example. M +20 -3 src/livepreview.cpp M +3 -1 src/livepreview.h http://commits.kde.org/kile/8346295484bd489f752593c171f1a15c47d02053 How is the performance on your machine now? I just compiled and opened my large document. I could not reproduce the performance lags described in the video. As long as I stay in the same line, KATE is very responsive. I will work again with large documents in two weeks and will re-open in case I notice any performance issues I did not notice now. Thank you for the fix! |
